Synopsis: Trying to access local web development server connected by WiFi to Android tether. Everything seems to be connected and operating correctly, but phone's web browser times out when accessing local server. Context: I've got an Android device running android-wifi-tether . It works as advertised. I connect to it from my Ubuntu 12.04 laptop running Apache 2.2.22. The laptop is manually configured to IP 192.168.2.100 in the hosts file. It can ping itself and access it's own web server through that address. The WiFi tether hotspot gives the laptop the same 192.168.2.100 address(Laptop was configured to match the hotspot address as a troubleshooting step, and could be wrong.) Using ping I can ping the laptop from the phone using the 192.168.2.100 address. Using portscan the phone shows port 80 open on the 192.168.2.100 address. So, everything looks like it's in place, but any attempt to browse to <code> http://192.168.2.100 </code> fails after a few moments with a 504(Gateway time out) Any help would certainly be help. Update: I've install SSH and migrated to Nginx on the server. Portscan now shows ports 22 and 80 open. Using ConnectBot I can login and get my own shell on the server machine by IP address. This should indicate that the network is functioning properly. I've also install the Dolphin browser on the phone to help verify that it's not an issue with the browser. Still I am curious if the browser is actually looking for the address first within the hotspot's IP space, or if it's looking to the internet, where that address will always time out. I am very new to the Android scene. I would really appreciate some feedback as to how to get my phone browsing a tethered server. The workflow I'm looking for makes connection to a local server critical. Thanks again. Solution As I assumed, due to HTTP Proxy settings the web request was bypassing local addresses. I found that if I changed the tether network to 10.* IP range my provider responded with "access to this url has been blocked." That made it evident that something was blocking some requests, and more than likely also leaving the others to die out in the unroutable nether-net. Used HTTP Proxy Settings to clear out HTTP Proxy address.

Problem may be caused by HTTP Proxy server. Proxies help to manage web traffic on the providers end, but can and probably will disrupt access to local addresses. Proxy options may be available in your network settings, but on many phones these options are hidden. An app such as HTTP Proxy Settings will give access to the hidden settings. Simply clear out the hostname and port for un-proxied access. Make sure to write down original values so changes can be undone.

Why does the stock Galaxy / Android app only keep the latest 25 emails? Its pretty annoying and lame for me who receive well over 50 emails per day in my work email. That means I cant even see a whole day's email without "loading more" and I don't always have Internet connection where I am. Is there any way to work around this issue? Edit: I am on ICS
|
The stock email application and many other I've tested present a list of 25 emails per page. The user can however load older emails on demand. This is done due to two main reasons: to prevent large transfers of data that end up using the device communication thus leading to a faster battery drain; to preserve memory consumption that in turn would leave your device slow and inefficient. I haven't found any option on all the applications I've tested that allows the user to define how much emails should be presented each time. I did find that the Gmail app auto-loads a new emails list when we reach the scroll limit, thus kinda facilitating the users trouble, but even with this scenario, the user needs to scroll all the way down to get the new list, and yet again, the Gmail app like the others, doesn't have a setting to define the number of emails to be loaded each time. Essentially, this is a status-by-design conception used by Android and app developers. You may come across with an app that allows you to go around this issue, unlikely it may be, but for the stock app, the reason as to why it loads only 25 emails at a time are the ones explained that sum up as performance issues.

Here is the point there is a secured WiFi connection - which password I don't know - but there is an device - Galaxy Nexus smartphone which is already connected to that WiFi and my Galaxy Tab tablet. There is any change to set GN as Bluetooth modem, to tether WiFi connection, for Galaxy Tab?

Android 4.0+ officially supports bluetooth tethering in both directions (and allows bridging to whatever the internet connection is (wifi/usb/3G)). You need: 1x device as tether host running Android 4.0+ that has wifi/3g/usb internet 1x client device running Android 4.0+ both devices are bluetooth paired enabled 'bluetooth tethering' setting on the host device: settings => wireless & networks: more => tethering & portable hotspot => bluetooth tethering You then can connect to the tethering profile: settings => bluetooth => paired devices/GN => profiles/Internet Access The GNexus fulfills all of that, however your P1000 cannot officially upgraded to Android 4.0 though, so you're out of luck or you have to install an aftermarket firmware (e.g. CyanogenMod9 , which is based on Android 4.0.4)

My Snow Leopard Mac doesn't recognize my Samsung Galaxy S2 for file transfer over USB, and it's starting to drive me nuts. I've tried the following: Connect Storage to PC <code> Settings > Wireless and Networks > USB Utilities > Connect Storage to PC </code> I've tried this several times on my phone, following the procedure stating that I should only connect after the phone asks me to, but it does not work. There is no "attach-button" in the pull down menu, like some claim there should be. Yet it seems that the phone notices that the USB-cable is connected. However OS X does not. No external storage pops up in Finder. I've also tried waiting for several minutes as I know this sometimes can take a while, but to no avail. USB Debugging <code> Settings > Applications > Development > USB debugging </code> When set to on, nothing happens. When set to off, nothing happens either. (It is automatically shut off when using <code> Connect Storage to PC </code> .) Android File Transfer I've also downloaded Android File Transfer, and while the phone finally recognized something by stating <code> MTP-Connected </code> in the pull-down menu, nothing happens in OS X, nor the Android File Transfer program itself. It just continues to demand that I attach the USB cable. I've also tried it in conjunction with both USB Debugging on and off, to no avail. When it's on, the phone doesn't detect any MTP. When it's off, the phone detects MTP. Either way, it seems that OS X doesn't detect jack... USB Prober The USB Prober on my Mac does detect something when I connect the USB to my phone, but I do not understand the message after the timestamp, that is: <code> [1] AppleUSBOHCI[0x56f9800]::SuspendUSBBus Processing WDH before suspending </code> . USB Cable I've tried with two different brand new cables. Made no difference. Please do not post answers suggesting the use of Kies, Bluetooth, Wireless, and the like. I want my phone to work over USB for a reason (speed and convenience).

tested on mac osx snow leopard and Mountain Lion: with your device unplugged go to settings-> developer options disable usb debugging; Go to Settings, in wireless and network section, go to "more"-> usb utilities Tap on "Connect storage to PC". Plug in your device to your mac and the tap on "Turn on USB storage" and OK. You should see your device just like an USB pen.

I have a Huawei u8160 running Psyke83's Cyanogenmod 7.2 14/8/2012 which had a package with it to apply usb-host mode kernel called usbhost1-cm-7-20120814-MADTEAM-u8160.zip . So I flashed the zip using clockwork mod recovery (from Rom Manager ) and was successful although when I started my phone and connected an USB mouse it didn't light(the mouse) and it wasn't working. I want to ask here,what's wrong? EDIT #1: I downloaded the app USB host controller and when I opened it it told me that "S3C USB Host driver NOT found!" EDIT #2: I've found this blog (it's in Hungarian so I translated it using Google) talking about exactly my state and it says that I need a Y-Cable to feed the usb peripheral with power, so I'm going to try that and then I'll report here. USB Y-Cable :
|
I've found it, I needed a Y-Cable and I needed to activate the usb host mode by using this command in the terminal emulator : <code> su insmod /system/lib/modules/ehci-hcd.ko </code> that activates the usb host mode. and the phone doesn't mount the flash drives so I have to mount it manually : <code> cd /dev/block ls </code> the terminal emulator should turn out something like uba,uba1 then create a folder in your sdcard called data (or whatever you like) and then type the one ending with 1 (i.e uba1) like this : <code> mount /dev/block/ub*1 /mnt/sdcard/data </code> (*) stands for the changed letter because it always starts with ub and ends in 1 but the third character changes between a,b,c,.... then open any file explorer and do whatever you want with data folder in your sdcard and then just unplug it, no need to unmount safely.

I am trying to help my Father debug an issue he has on the TF300 since it upgraded to Jelly Bean. We are both unable to open a vCard file from email or from Astro file explorer. It appears to the user that nothing happens when he hits view in Gmail. He receives vCard emails all of the time from his work. I can save it, open "people" and then import it, but I cannot import it from Gmail view it. We can open it from Gmail on Jelly Bean on both my Galaxy Nexus and my Nexus 7. This sounds like a file association issue, but there are no defaults under Contacts. Does anyone have any ideas on how to debug this? Is there an easy way without USB debugging to determine what program gets called? Edit: What is the easiest way to log every process opened after a file is clicked on? I am happy to use USB debugging at this point.

In this case an OS upgrade solved the issue. For someone in a similar situation without an OS upgrade (or other fix) in sight, it might be worth taking a look at VCard Manager (which claims to be able to open all types of VCards) or Contacts VCF , which says to open any <code> .vcf </code> file: VCard Manager and Contacts VCF (source: Google Play; click images for larger variants)

What is the fastest way to transfer huge files (e.g. 500MB) between two android powered devices? Bluetooth? WiFi direct? Beam? or maybe USB on-the-go?
|
There are many variables that affect the performance of each method you've mentioned. Additionally there's also the necessary configuration and requirements that each device must have in order to have solutions like this working. As requested, lets summarize and compare possible performances between USB; Wi-Fi and Bluetooth: USB: USB performance can be extremely low or very high, depending on the available USB version, which in turn, combined with the SDcard reading/writing speed on each device allows us to accurately measure and ascertain the transfer speed. There's also the physical limitation of the USB cable length that for some scenarios becomes a limitation. USB 1.0 : 1.5 Mbit/s (Low-Bandwidth) and 12 Mbit/s (Full-Bandwidth) USB 2.0 : 480 Mbit/s (effective throughput up to 35 MB/s) USB 3.0 : 5 Gbit/s (625 MB/s) which is more than 10 times as fast as USB 2 Wi-Fi Wi-Fi loses limitations like cable length, but then again we need to account for the 802.11 protocol being used, the signal strength and range to accurately measure results: <code> ┌────────────┬─────────────────────────────────┬──────────────────────────┐ │ Protocol │ Data rate per stream (Mbit/s) │ Approximate range (m) │ │ | ├────────────┬─────────────┤ │ | Bandwidth of 20 MHz | indoor | outdoor │ ├────────────┼─────────────────────────────────┼────────────┼─────────────┤ │ 802.11a │ 6, 9, 12, 18, 24, 36, 48, 54 │ 35 │ 120 │ ├────────────┼─────────────────────────────────┼────────────┼─────────────┤ │ 802.11b │ 1, 2, 5.5, 11 │ 35 │ 140 │ ├────────────┼─────────────────────────────────┼────────────┼─────────────┤ │ 802.11g │ 6, 9, 12, 18, 24, 36, 48, 54 │ 38 │ 140 │ ├────────────┼─────────────────────────────────┼────────────┼─────────────┤ │ 802.11n │ 7.2, 14.4, 21.7, 28.9, 43.3, │ 70 │ 250 │ │ │ 57.8, 65, 72.2, │ │ │ │ │ │ │ │ │ │ With Bandwidth of 40 MHz: │ │ │ │ │ 15, 30, 45, 60, 90, 120, │ │ │ │ │ 135, 150 │ │ │ └────────────┴─────────────────────────────────┴────────────┴─────────────┘ </code> More about Wi-Fi protocols from Wikipedia . Wi-Fi Direct Wi-Fi Direct, initially called Wi-Fi P2P, is a Wi-Fi standard that enables devices to connect easily with each other without requiring a wireless access point. Here the communication is performed at typical Wi-Fi speeds for everything from file transfer to Internet connectivity. Essentially, Wi-Fi Direct falls under the same values presented at the Wi-Fi table (yet again keeping in mind that signal strength and range are the key factors for a good performance). More about Wi-Fi Direct from Wikipedia . Bluetooth While we need to ascertain several influencing factors to determine if Wi-Fi is faster than USB, Bluetooth is with no doubt in last place when we speak about transfer speed. Designed as a proprietary open wireless technology standard for exchanging data over short distances, the maximum speeds are below the two concurrent options: <code> ┌─────────────┬─────────────┬─────────────────────────────────────────┐ │ Version │ Data rate │ Maximum application throughput │ ├─────────────┼─────────────┼─────────────────────────────────────────┤ │ 1.2 │ 1 Mbit/s │ 0.7 Mbit/s │ ├─────────────┼─────────────┼─────────────────────────────────────────┤ │ 2.0 + EDR │ 3 Mbit/s │ 2.1 Mbit/s │ ├─────────────┼─────────────┴─────────────────────────────────────────┤ │ 3.0 + HS │ │ ├─────────────┤ theoretical data transfer speeds of up to 24 Mbit/s │ │ 4.0 │ │ └─────────────┴───────────────────────────────────────────────────────┘ </code> More about Bluetooth from Wikipedia . Android Beam Being a fairly recent technology, Android Beam allows users to transfer data between devices with Near Field Communication (NFC) capabilities. NFC is even slower than Bluetooth (both short-range communication technologies) and is limited to about 20cm of range getting up to 424 kbit/s. On a positive note, NFC sets up more quickly than standard Bluetooth and the connection between two NFC devices is automatically established: Technical comparison: <code> ┌──────────────┬────────────────┬────────────────┬──────────────────────┐ │ Aspect │ NFC │ Bluetooth │ Bluetooth Low Energy │ ├──────────────┼────────────────┼────────────────┼──────────────────────┤ │ Network Type │ Point-to-point │ WPAN │ WPAN | ├──────────────┼────────────────┼────────────────┼──────────────────────┤ │ Range │ < 0.2 m │ ~100m (class1) │ ~50 m │ ├──────────────┼────────────────┼────────────────┼──────────────────────┤ │ Bit rate │ 424 kbit/s │ 2.1 Mbit/s │ ~1.0 Mbit/s │ ├──────────────┼────────────────┼────────────────┼──────────────────────┤ │ Set-up time │ < 0.1 s │ < 6 s │ < 0.006 s │ └──────────────┴────────────────┴────────────────┴──────────────────────┘ </code> Only relevant aspects to this answer, for full table see Wikipedia . Summary Based on the specifications for each method and their respective version, my classification ordered by fastest-to-lowest would be: USB assuming version 2.0, since 1.0 is way slow and outdated Wi-Fi / Wi-Fi Direct Bluetooth Android Beam

I got a very long list of free hotspots and friends/family networks on my phone. Recently I bought a tablet and I'm trying to find a way to copy the wireless manager list to this new device. Any idea how to do that? Both devices are rooted and running ICS.
|
As you are rooted: Wireless network data are stored in <code> data/misc/wifi/wpa_supplicant.conf </code> -- so you could basically copy all its <code> network </code> entries from one device and insert them on the other. The entries look like <code> network={ ssid="Telekom" key_mgmt=NONE priority=42 } </code> An easier way would be using the App Wlan Backup & Recovery (root): Backup all entries on one device, and restore them on the other. As you can see in below screenshot, the tool can even send the backup by mail -- so transfer to the other device should be easy: But reading the comments on this app suggests it does not always work as expected: Users even recommend to use the manual way I described above. Another option is using Titanium Backup, and restore the Wifi data on the other device. I did that successfully a couple of times, also cross-device and cross-ROM. Third option is offered by the app Wifi Passwords (about USD 1), which allows you to share networks.

I have a Galaxy S2 with NFC (GT-I9100P) and I wish to have root access to properly administrate my phone. I've been looking at various forum posts on different sites and I've just been getting more and more confused as to what I need to do. From what I understand, I need to flash an unsecure kernel to the phone (with ODIN) to get root access, then I can flash the stock firmware back onto the phone and retain root access. Is this correct? Further information: My baseband version is <code> I9100PBVLP7 </code> kernel version: <code> 3.0.15-I9100PBVLPA-CL364024dpi@DELL169 #3 </code> and my operator is Orange UK. I've managed to obtain the firmware version that is on my phone already through sammobile.com, I just have no idea what I need to do next. Reward If anyone can help me to get root access on my stock firmware I will give them as much bounty as I can when the question is eligible for it.

If all you need is root access, try flashing the Siyah kernel via ODIN. Ensure you get the S2 version, as the dev has one for the S3 as well. Also, you will need the TAR version as you will flash it via ODIN (at least for the first time). Later instances, you can get the ZIP format and flash it via CWM (ClockworkMod recovery, which is built into the kernel). Apart from features like more processor steps, you can also overclock/underclock, adjust various parameters and have features like Backlight Notifications. Since you will flash this kernel, you DO NOT need to flash the firmware. You can keep the stock firmware and your data intact. This kernel automatically installs root access so your primary requirement is also fulfilled. As with all operations, ensure you have an off-site backup of all your data. As an aside, once you install the kernel, get the ExTweaks app from the market which is designed especially for this kernel and offers a GUI/frontend to access many under-the-hood features. Assuming you have all the drivers installed, here's how you go about it: Download the TAR file of the Siyah kernel. Note that the latest series is for ICS, in case you're running Gingerbread, search for and download the appropriate older version of the kernel. Start ODIN and connect your phone via the USB cable AFTER you enter DOWNLOAD MODE (Press Vol down + HOME + POWER button simultaneously for a few seconds after completely shutting down phone. At the warning screen hit Vol UP to confirm entry to download mode). Once connected, you should see a COM port number with a yellow background. In the ODIN program, press the PDA button and point to the TAR file. make sure ONLY Auto-reboot is ticked and then click START. If all goes well, you should see a green box with PASS! shown after which your phone will boot up. It may take a minute or two, so don't panic. Refer to the FAQ and the respective threads on XDA-Forums for more info.

Everyone knows that start Android camera sometimes is a pain, specially if you wish to take a picture of something that lasts only some seconds. What I want to know is: is there a way or an app that makes the camera start faster? Note that I'm not asking about picture shot, though this is important too. I think that as soon as the camera is started, this is not a big deal.

Try InstaCamera Pro from Google Play Store. It starts very fast and has preferences to start camera and takes photo just by a single touch from home screen of your phone: InstaCamera is the quickest way to take a photo with your phone. There's no long process: just press the widget and it takes a photo, then closes just as quickly. The paid PRO version is supposed to be faster than the free version .

I have rooted my MT11a with UnlockRoot v2.4.2 and the "superuser" app has appeared. The tutorial said my phone should be requesting to upgrade 4.0.2.A.0.42 to another number ending in .62, but the Update Center says the phone is completely up to date. I should be getting the BusyBox after this update, but the update is not happening. Have I missed a step? The phone is working just fine.

If it doesn't work out of the box, which is the case with many Android phones, then you have a few different options: A launcher replacement which adds this feature (may not work with all ROMs) stackexchange-url ("A custom ROM like cyanogen mod, which has this feature built in.")

I am used to from cyanogen mod to be able to toggle on/off wi-fi, gps, data, plane mode etc Also I was able to configure what is going to be available to toggle. Now in HTC Sense version 4.0 that runs on Android 4.0.3 I cannot find anything like that. Do I have to install (and probably pay) for a widget or I missed this a must feature in the Sense? Could you recommend a widget that would allow me to do so?

There are a lot of toggle switches available. Some even come pre-installed -- just check it out: go to your homescreen long-press on an empty space select to add a widget scroll through the list of available widgets select the one you want to use Usually, there are a lot of separate widgets to toggle either Wifi, GPS, ... -- but also a "power-widget" (or "energy-widget") should be available, which is a combination of several widgets. If you are still not satisfied with what you find there, the playstore is full of alternatives: Elixir 2 with its Elixir 2 - Widgets being the most famous and high-rated 1 , and can even be integrated into the notification area Power Toggles being another alternative 2 -- also can be integrated with the notification area Just to give you two examples -- as said, the playstore has many more. Below you find a screenshot from Elixir 1 and Power Toggles 2 , to give you an idea of what they can do.

I have a lot of music encoded in Apple Lossless (ALAC), but Google Play Music doesn’t seem to support it. Instead Google Play Music supports FLAC , but iTunes doesn’t support it. I don’t care how encoded my music are, but want to encode these without any loss. How do you guys manage your lossless music using iTunes + Google Play Music? I believe it’s not only my problem. Edit : Okay, I finally gave up, and encoded my all files encoded in ALAC/FLAC to normal AAC. There seems no way to use both at a time as of now.
|
First are you talking about storing the music on your Android device or on the Google servers? If you are planning on streaming music to your device from the Google Music Play servers then you can't store your music in a lossless format see this page about formats on Google Play Music, and notice this line: FLAC, ogg, and aac files are transcoded to 320kbps mp3 However, if you want to store the music locally on your device then your question makes more sense. There are a few ways to put ALAC music on your Android device in FLAC Keep your library in ALAC and convert songs to FLAC as you want them. Then move the new FLAC files to your device. A program like Max should be able to handle the conversion for you. Convert all of your ALAC files to FLAC in place and then use fluke to enable FLAC playback support in itunes. What option you select depends on how much you like to keep your OS free of plugins like fluke and how ofter you are moving music to and from your device.

To get a privileged shell you need to modify the following lines to the given values in the default.prop file ro.secure=0 ro.debuggable=1 persist.service.adb.enable=1 I have the extracted the recovery image of my phone model : So is it possible to modify the following values in the default.prop file, repack the image and flash it using fastboot(bootloader is unlocked) to get a privileged shell, and then copy the su binary after remounting system as read/write? Do I need to change any other values in any of the files? And will it work, theoretically at least?
|
This approach will work (provided there are no proprietary funny locks in place anywhere), but the recovery partition is no party to it from the very beginning. The default.prop is overwritten on bootup, copied from the boot partition, which is not a directly accessible file system. You need an image of the boot partition, which you will then unpack, make the change, and repack. Assuming you know how to go about doing all that (since you say you tried it with the recovery), I must warn ahead that often times it is necessary to include the base address when making the image with mkbootimg. There is no way to know when it is required, so it is safe to always include a base address. You can follow a tutorial here: www.freeyourandroid.com/guide/extract-edit-repack-boot-img-windows The script includes the od command with which you can get the base address, in case you want to make your own script. For more on the manual steps (for reproducing on GNU/Linux): android-dls.com/wiki/index.php?title=HOWTO:_Unpack%2C_Edit%2C_and_Re-Pack_Boot_Images I do not recommend use of the unpack/repack scripts, as they have hardcoded lines not portable across cases. Use split_bootimg.pl, then gunzip and cpio extract it, after which you will again use cpio and gzip it, followed by the mkbootimg command. The only exception is for MTK65xx devices, where you will need the relevant unpack/repack tools (because they have very different offsets; you will also skip the mkbootimg as the repack script does it for you): github.com/bgcngm/mtk-tools And here is an on-going example of a Chinese rebranded phone going through the same thing to finally get root: forum.xda-developers.com/showthread.php?t=1818146&page=5 I'm sorry I have to strip off proper links, but I am apparently considered potential spam. Also, I've not been rather thorough because I'm not really sure you'd want more verbosity.

I installed Apex Launcher on my S3. It takes some configuring before it is useful, so I didn't assign it to the default action of my home key.

You can also run Apex Launcher from the app drawer of your default "stock" launcher. Navigate to Apex settings > ADVANCED > SET DEFAULT LAUNCHER which will do the same thing - clear the default action and display the popup menu allowing you to choose from the launcher apps currently installed on your device.

I've read ways but they don't block/disable ads.
|
Free applications usually come with ads, since they are used by the developer to monetize its work : Advertising is one of the means to monetize (make money with) mobile applications. Two methods to disable ads: Unrooted device: Buy the donate version It's getting common among developers to have two versions of their application, one free filled with ads, and one "donate" version where you pay a extra-small-amount and get rid of the ads while helping the developer. Additionally, there are other forms of donate to help the developer and get rid of the ads, since they vary alot, best is to read the application summary. Rooted phones: There are several applications available from Google Play Store with the sole purpose of blocking ads from the device and applications. Essentially, they nullifying requests to known host names in the system hosts file. AdFree Android by BigTinCan.com is amazing for this end. Personally I don't like the idea of blocking ads since we are essentially preventing developers from earning their day-to-day bread.

I used to have an app on my Desire HD that I think was called Something Dog. When launched, it would list all the installed apps and whether they were the latest versions. My Desire HD crashed a while ago, and all my data was lost. I've since bought a One X and I'd like to have this app again. Does anyone know what it's called?
|
The "dog" you are talking about is aTrackdog. :) It queries your installed apps and compares them to the latest known versions.

How can I check if installed apps are latest versions?

I'm using a custom ROM of CyanogenMod 7 (Android 2.3.5) on ZTE Racer. The ROM came with some default system apps like Gmail, Google Translate, Youtube and Adobe Reader. The old version of these apps are kept in internal storage even if you update them, so to save space I uninstalled the updates and them removed them using Root Manager . The problem is that when I installed the updated versions from Market, they force close during opening (I found out later that Google Translate force close only when trying to translate something). I had backed up everything before uninstall, and I noticed that if I install the backed up version manually and then update it through Google Play, they work fine. Checking the storage space left, I can say that the old versions were this way deleted, so I suppose the result should be the same. Since I did not notice that Google Translate wasn't working, I deleted the backed up apk file, so I can't put it to work again. My question is: anyone knows why does this happen? And if so, how could I make the updated version of Google Translate to work now that I do not have the old default apk anymore? Edit: I tried installed again to trace the exact error message and it is now working, though I have done anything explicitly.
|
I cannot say for all apps you listed -- but for some, the following applies: Some system apps (as e.g. the market/playstore app) have to be present in <code> /system </code> in order to work. For the Playstore app, the reason is: The permission to install other "packages" is only granted if one of the following two conditions is met: it is signed with the same certificate as the system (ROM) itself -- which does NOT apply in your case, due to the custom ROM used it is installed as "system app" (i.e. below <code> /system </code> ) -- which did no longer apply in your case, since you uninstalled the app from there Expecting the pre-conditions given, developers might have forgotten to include a check and implement appropriate exception handling -- which then may lead to the described force-close. Similar constellations might apply to other apps/packages as well -- though I'm not sure what should make the Google Translate app so special (maybe it has some special hooks I missed). You could try to find out by following Roxan's advice, to integrate the app as "system app" again using e.g. Titanium backup , and see if it still force-closes.

I want to know what happens to the battery (does it charge/discharge/stay constant?) when the device is in bootloader or recovery mode. In both of these modes, a USB may or may not be connected. If the battery does charge, could that possibly be a feature that could be a result of the installed recovery/bootloader, or could the charging feature be hardware dependant?
|
Charging control is done via hardware to prevent ruining the battery in case of software errors. That is why (most?) devices charge even when powered off. The status display that is then shown is just a "minimal OS" that queries the current status from the battery charger hardware.

I downloaded Tweetdeck for my new Galaxy S 3 and when it is not running in the task list or in the <code> app manager | running apps </code> it still notifies me of new tweets. How can I see this task running and how to disable it? I don't see it in services or in the Tweetdeck options to disable background services.
|
In Tweetdeck, each column has separate notification and update settings. Tap the menu key, then Column Settings. Switch notify off, and set your desired update interval, or move the slider all the way to the right to select "Manual".

Every day I get a notification on my Inc2 that there are app updates available in the market. Is there a way to change the frequency of these update checks? I see no reason to be prompted to update my apps on a daily basis and this is a little annoying. I would like to be able to only have it check for updates weekly.
|
You can turn off automatic update checking by pressing menu and than settings in the play store. You can then manually go to my apps to update them. This will not greatly increase the work you have to do, because even if there is a notification once a week it would still require you to confirm the updates. There is no option however to change the frequency of the automatic updates.

The audio jack is busted so I want to stream the internal sound to my Android phone and use my headset on that phone instead. No, not just music files. I mean the whole internal sound coming from the laptop. That includes error sounds, clicking sounds (if any) the recycle bin being emptied, etc. Isn't there anything other than Airfoil that can do this?
|
SoundWire Free appears to do this...but the free version has limitations: The free version of the application identifies itself by voice every 30 minutes and displays ads. The full version can handle up to 10 connections at the same time, and has no ads or voice identification. Please consider purchasing the full version of SoundWire if you'd like to support the developer. Edit to add: That page has SpeakerShare in the "others viewed" links, which appears to be an open source app to do the same thing. The lone comment mentions it's delayed (likely due to buffering/network latency), but things like videos can be worked around (VLC offers an audio synchronization option, for example).

I have Samsung Galaxy S II with Android 4 . If I configure my phone to GSM/WCDMA (automatic) mode, I have problems when I receive or make a call. Usually I lost the call or the other person cannot hear me. In my city 3G network is not very good. I solve this problem changing the mode to GSM only (manually) and then make the call. Is there a way to configure my phone to change from WCDMA to GSM automatically when I make or receive a call? I've installed 2G/3G OFF application, but it is still manual.
|
If you constantly get a poor 3G signal, you may want to switch the signal preference to favor 2G instead of 3G. Here's a way to do it on ICS: In dialer, press <code> *#*#4636#*#* </code> Go to 'Phone Information' Swipe to this 'Set preferred network type' Assuming it is 'WCDMA preferred', change it to 'GSM Auto (PRL)' This setting will change its signal quality threshold, allowing it to switch from 3G to 2G 'earlier'. Use at your own risk though... To address your question of automatically switching signal when you make a call , you might be able to hammer something out on Tasker if you are so inclined (I may give it a try later to satisfy my own curiosity xD). One problem is forsee though, is that I believe it takes a bit of time to switch signals, so it might affect your call (or its quality).

I'm looking for a "find my phone" app that can be activated from another app instead of a webpage. The scenario is simple, my wife misplaces her android phone frequently. I'd like to be able to quickly launch an app from my android phone or tablet and activate a find me siren on her device. So far all of the apps I've found require you to long into a bloated webpage first. Edit: It should work in reverse too, so I can find my tablet (which does not have a phone number of course) from her phone.

"Find My Phone Siren" does what I was looking for (app to app siren). It also uses google to sign in so you don't need yet another account. Only drawback is that it costs $1.97.

I need information about which applications or hardware features discharge the battery. Built-in Android option for this doesn't fit because not all devices have it. Also it would be a great advantage if the solution would send statistics via email.
|
You could take a look at SystemPanel 1 or System Tuner 2 . Both let you monitor your ressource consumption (not only battery), and (at least in their respective Pro versions) also offer to do so in background, collecting data for later evaluation. System Tuner 2 also offers a bunch of nice widgets 3 for your homescreen, if you need to watch things for a while. EDIT: After seeing Mihic's comment above, I noticed I missed another important point: While up to Froyo, "dialing" the magic number <code> *#*#4636#*#* </code> brought up a nice system menu (it still does that part) including many battery stats, the latter (battery stats) have been removed since Gingerbread. If your device is rooted, BetterBatteryStats can bring those back -- and do a great deal to help you identifying battery hogs: These two screenshots show you the most important information BetterBatteryStats provides: Which apps used the most battery power while the device tried to sleep 3 -- and those who kept the device awake 4 , preventing DeepSleep and such "PowerSave Mode". Just helped me getting 20% more battery out of my device ;)

I'm currently using a Google Nexus tablet tethered via Bluetooth to a Samsung S3 for internet. Two things are annoying me. First, if I take the phone away from the tablet (go out for lunch), the tablet disconnects and has to be manually reconnected. Is there a way to have that happen automatically? Second, Bluetooth tethering, i.e. the internet sharing part needs to be switched on each time the bluetooth is switched on (or perhaps just after power cycling) on the S3. Is there no way to have that default to on? Thanks
|
I'm doing the exact same thing, except with my Captivate, and I ran into the same problems. To solve them, I use three apps across the two devices. On my N7, I use Tasker to detect when I lose wifi connection and use Bluetooth Auto Connect as a Tasker plugin to automatically connect to my phone. On my phone, I use Bluetooth Auto Tethering , which automatically turns on Bluetooth tethering when you start your phone. As a bonus here is a link to my Tasker profile/tasks which does all this stuff. I think you can just import it into your Tasker.

Having spent some time researching what actually goes behind rooting an Android phone, the main reason that leads to the ability root is an inherent vulnerability on the Linux kernel that leads to the exploit and getting the 'su' binary to be installed. My question is: How come the OS is not hardened yet? Who is responsible? This is a Linux OS we're talking about, which is considered "secure". Yet, people always find a way to get in and root devices.
|
it's not really the "linux OS", it is the linux kernel. The vulnerability is not necessarily in the OS, or the kernel. There are different exploits that are used. I remember some device being able to load any zip file in the recovery if it was "pre-pended" by a signed zip file. So they used a signed zip and added an unsigned zip to the end of the file. I think this exploit was for the Original Droid. No software is 100% bug free. if it was, then even a mature product like Windows would not have to do security patch releases every month. No matter how smart the developer is, or thinks he is, more likely than not, there is probably someone smarter (or at least they may know more about exploiting code). When exploits are discovered, Google (or the manufacturer) has (usually) patched them. But since a lot of the devices don't receive updates very often, the exploit remains available.

One thing I have noticed about almost all android-powered smartphones is that they find it so difficult to connect to ad hoc wireless hotspots. I can connect most wifi enabled devices to this ad hoc connection(created with an iPhone 3G app, MyWi) but not android phones. Is there a fix for this situation?
|
As far as I know, this is something inherent to Android itself. I'd go further to say that if you've ever used an Android device that could access ad hoc WiFi it's something the manufacturer added. I would love it if someone could prove me wrong on that though. So as for why, I suppose only Google knows.

I have an stackexchange-url ("issue with inconsistent UIDs"). I would like to know how to manually find out the ID of a folder (specifically the /data partition). I think that it should be the same concept of an usual unix/linux filesystem but... I'm evidently getting older for this stuff :-) From the Astro app I can see the details of the /data partition but it only tells me <code> d-- </code> and I cannot find any user id. Actually, I have not set up any account on this phone, so there should be (I guess) only one UID present (the default one) apart from the system daemons etc. Maybe for this reason it doesn't show up? Is there another, more powerful/informative app to be used? A file manager of some sort, a terminal console would be ideal for me.
|
I'd personally recommend using a terminal emulator or <code> adb shell </code> and then using the <code> ls </code> command. You can get the UID's listed by name if you use the <code> -l </code> flag and listed by number with the <code> -n </code> flag. Note that in the <code> /data </code> directory you'll need root permission in order to index the files/directories, so <code> ls </code> will fail with a normal user: <code> root@android:/data # ls -l drwxrwxr-x system system 2012-08-27 14:29 anr drwxrwx--x system system 2012-08-29 17:46 app drwx------ root root 2012-08-27 00:54 app-asec drwxrwx--x system system 2012-08-27 00:54 app-private drwx------ system system 2012-08-27 00:55 backup drwxrwx--x system system 2012-08-29 17:46 dalvik-cache drwxrwx--x system system 2012-08-29 17:34 data drwxr-x--- root log 2012-08-27 00:54 dontpanic drwxrwx--- drm drm 2012-08-27 00:55 drm drwxrwx--- gps system 2012-08-27 10:29 gps drwxr-x--x system system 2012-08-27 00:54 lightsensor drwxr-x--x root root 2012-08-27 00:54 local drwxrwx--- root root 1969-12-31 19:00 lost+found drwxrwx--- media_rw media_rw 2012-08-27 14:10 media drwxrwx--t system misc 2012-08-27 00:54 misc drwx------ root root 2012-08-27 10:30 property drwxrwx--x system system 2012-08-27 00:54 resource-cache drwxr-x--x system system 2012-08-27 00:54 sensors drwxr-x--- root shell 2012-08-27 00:54 ssh drwxrwxr-x system system 2012-08-30 11:05 system drwxr-xr-x root root 2012-08-27 00:55 tf drwx--x--x system system 2012-08-27 00:54 user root@android:/data # ls -n drwxrwxr-x 1000 1000 2012-08-27 14:29 anr drwxrwx--x 1000 1000 2012-08-29 17:46 app drwx------ 0 0 2012-08-27 00:54 app-asec drwxrwx--x 1000 1000 2012-08-27 00:54 app-private drwx------ 1000 1000 2012-08-27 00:55 backup drwxrwx--x 1000 1000 2012-08-29 17:46 dalvik-cache drwxrwx--x 1000 1000 2012-08-29 17:34 data drwxr-x--- 0 1007 2012-08-27 00:54 dontpanic drwxrwx--- 1019 1019 2012-08-27 00:55 drm drwxrwx--- 1021 1000 2012-08-27 10:29 gps drwxr-x--x 1000 1000 2012-08-27 00:54 lightsensor drwxr-x--x 0 0 2012-08-27 00:54 local drwxrwx--- 0 0 1969-12-31 19:00 lost+found drwxrwx--- 1023 1023 2012-08-27 14:10 media drwxrwx--t 1000 9998 2012-08-27 00:54 misc drwx------ 0 0 2012-08-27 10:30 property drwxrwx--x 1000 1000 2012-08-27 00:54 resource-cache drwxr-x--x 1000 1000 2012-08-27 00:54 sensors drwxr-x--- 0 2000 2012-08-27 00:54 ssh drwxrwxr-x 1000 1000 2012-08-30 11:05 system drwxr-xr-x 0 0 2012-08-27 00:55 tf drwx--x--x 1000 1000 2012-08-27 00:54 user root@android:/data # </code>

I am at home and I would like to be sure that the data connection is always going through the Wi-Fi rather than the (expensive) data connection. Is it enough to simply turn on Wi-Fi and connect to the (password protected) network? How can I control that the download is happening through the right connection? Can sleep (or other events) disable/change/toggle this setting?
|
In Android, AFAIK, when you connect to an active Wi-Fi network, mobile data (GPRS, 3G, etc) will be disabled (even if are turned on) temporary. So it would be OK to just connect to the Wi-Fi network. But, if you want to be sure about disabling mobile data, you should go to Settings -> Wi-Fi and Networks -> Mobile Data and uncheck the option to disable mobile data. (in ICS it's in Settings -> Wireless and Networks -> More -> Mobile Networks)

You can export the contacts from gmail, than edit in whatever editor you want and than import back to google. Your phone should then update the changes. How to export from gmail: http://support.google.com/mail/bin/answer.py?hl=en&answer=24911 and how to edit the CSV files: http://support.google.com/mail/bin/answer.py?hl=en&answer=12119&topic=1669027&ctx=topic There are also related links on the left (for import and other questions) If importing them back to google makes duplicates, remove all google contacts and then import from CSV. If your phone does not currently use google contacts sync for it's contacts you can try a similar "hack" by exporting contacts to the SD card and then importing them back.

I am an HTC Wildfire user. I have successfully installed CyanogenMod 7.2 on my device, but after over a year of use I want to bring it back to the original HTC rom, if possibile. In order to do that I have tried to follow a few tutorials that promised to do just that. Needless to say they all failed. My HTC has mounted HBoot 0.80.007 and it is in S-On state and, maybe I am wrong, but I figured I should update the HBoot to 1.01.001 at least and in order to do that I need to acquire the S-Off. So I tried to download the Revolutionary utility but I had no luck in providing my Wildfire serial number. As a result I am clueless about what to do. Can anyone please illustrate what I need to do to bring my device back to the original rom?
|
In one of my attempts to I was trying to upgrade the hboot from 0.80.0007 to 1.01 and luckily flashing the device with RUU_Buzz_Froyo_HTC_WWE_2.22.405.1_Radio_13.55.55.24H_3.35.20.10_release_160191_signed.exe it also brought my Wildfire to the stock rom.

Will Dropbox delete a file from my cloud storage after I upload it? So if I upload a photo with the Dropbox app, then delete it from the phone, will it remain in my Dropbox storage?
|
If you delete a file from your mobile device, the file remains on your Online storage. To have the file permanently deleted, you need to delete it from your online Dropbox account, accessing it via their website. I've just run this exercise (to prove the theory) : Take photos; Sync Dropbox; Delete photos from my device; Access laptop; Photos were downloaded; Access Dropbox website and login to your personal account; Delete photos; Photos were automatically removed from Laptop and a notification was presented asking if I wanted to undo the operation.

Better something than nothing. However, with Ace 2 the story is worse -- all I see is sequence of dots, and I have real difficulties to type anything correctly.

I do not have your phone model on hand to try, but you can give this link a shot. Generally, just go to Settings > Security > check Make passwords visible. This is true for my phone (HTC Desire, BCM 4.0.4). Hope it works for you.

Is there a way to make my tablet understand that an app downloaded or upgraded through my OEM is just as safe as something downloaded through Google?

You should go to Settings -> Security and check the option: Unknown Sources (or something like that). then your tablet would allow you to install apps from everywhere.

I want to remove a bunch of images and it is extremely slow in Android. I want to edit things directly in Desktop, maybe such services with something like Google Picasa (?). In other words, how can I edit my images on the memory card of the Android device on Desktop? The Desktop and the Android are linked with the same Google account.
|
You can do this via WiFi, using a remote management app like e.g. AirDroid or, when on Windows, MyPhoneExplorer . There are a lot more apps like this, and they give you the added benefit of being able to manage a lot of other things remotely -- as e.g. reading/writing SMS, managing apps/contacts/ringtones, copying files between your device and your computer, and sometimes even backup stuff. Most of them (like the mentioned AirDroid 1 ) start a web service on your device, which you then can access with your browser. This often looks like a "virtual PC" (see screenshot below). Others (like here MyPhoneExplorer 2 ) have a native PC-Client, which can even do more (like here: synchronizing with Outlook and others). AirDroid managing pictures MyPhoneExplorer Windows Client

I use ASUS Transformer with the keyboard attached. In Google Chrome for Android, I would like to use Ctrl +Click to open up a new tab which contains the website where the link is pointing to, just as I would on my desktop computer. But somehow this does not work on my Android device? I can use for example, Ctrl + tab to open new window. BTW I click with my touchscreen, maybe this matters?
|
For now, AFAIK, every action associated with a mouse click can be accessed using a touch or a long-touch. Combo using a key-press and a touch aren't well supported (if supported at all) . Long-Touch over a link, gives you a popup with: Open in new Tap; Open in incognito mode; Copy link address; Save link as.

Samsung Galaxy Ace 2. Let's say I have 3 desktops, I can scroll from 1 to 2, from 2 to 3 and... from 3 to 1. The last one is undesired by me, so how I can disable this effect?
|
It is likely that the option does not exist on your stock phone launcher (can't confirm that, I have a different phone), but if it does, it should have the keywords "looping", "wrap around", "circular scrolling" in the settings. I would recommend installing one of the following 3rd party launcher instead, which do not wrap around by default, and provide other useful functionality: Go Launcher Ex ADW.Launcher LauncherPro Go Launcher Ex appears to be in active development though so you'll probably have better support going with it. There are other launchers as well but these 3 are the ones I have used before.

I have been backing up my Nexus 7 with <code> adb backup </code> to back up all files into an encrypted backup. I see that you can restore from a backup with <code> adb restore </code> , but that would wipe all my existing data on the device. How exactly would I extract one App's data from this encrypted backup file?
|
Just for reference of others, here is some background on the .ab file format. The Android Backup (*.ab) file is a compressed TAR file. It is compressed using the DEFLATE algorithm. On top of that, there can be AES encryption used. This is determined when you create the backup, if you enter a password then the backup is encrypted, otherwise; there is no encryption, it is only compressed. The HEADER of the file is a little different then a normal DELFATE archive. It contains information about the backup and looks like the following: <code> ANDROID BACKUP 1 1 none </code> The first line is the "Magic" line. The next line is the version of the Android Backup file format. The next line is a boolean (true or false, 1 or 0) indicating if the file is compressed. The last line is the type of encryption. This example is not using any encryption. If there was a password, the line would read "AES-256". After that is the encryption cypher. If no password, then the DEFLATE "archive" starts. It is compressed using the Java Deflater. Which, from a developers perspective, causes issues if you want to use anything besides Java to extract it. I haven't been able to find anything that can deflate it using the same algorithm, even though all that I have found (for like C#) are supposed to follow the "SPEC". With that said, there is an open source project under the Apache 2.0 license, written by Nikolay Elenkov that will allow you to extract the .ab in to a tar file. Usage: <code> java -jar abe.jar unpack <backup.ab> <backup.tar> <password> </code> If you are not sure how to really use that (which is beyond the scope of this answer) the next version of Droid Explorer v0.8.8.7 (available here) will allow you to do exactly this, and more, right from Explorer. You can read more about the features on my blog (yes, i know, shameless plug. I do that when it fits the question)

There are at least a dozen "Faster GPS Fix" apps in the Play Store -- one is even a $5 paid app -- and they remind me of those RAM Booster/Optimizer utilities of the 1990s. What do they do -- and the better question is: why doesn't Android do this by itself?
|
One of the apps you have a picture of, the venerable GPS Status & Toolbox, describes this claim in the app description: Keep your GPS fast: reset it or download A-GPS data regularly for faster fixes Wikipedia does a great job defining the basic concepts behind Assisted-GPS: Standalone GPS provides first position in approximately 30–40 seconds. A Standalone GPS system needs orbital information of the satellites to calculate the current position. The data rate of the satellite signal is only 50 bit/s, so downloading orbital information like ephemeris and almanac directly from satellites typically takes a long time, and if the satellite signals are lost during the acquisition of this information, it is discarded and the standalone system has to start from scratch. In AGPS, the Network Operator deploys an AGPS server. These AGPS servers download the orbital information from the satellite and store it in the database. An AGPS capable device can connect to these servers and download this information using Mobile Network radio bearers such as GSM, CDMA, WCDMA, LTE or even using other wireless radio bearers such as Wi-Fi. Usually the data rate of these bearers is high, hence downloading orbital information takes less time. If your phone's A-GPS cache is corrupt or stale, forcing a refresh can be beneficial. Normally, Android does in fact take care of maintaining this cache automatically. I've personally only used this app to help diagnose and solve GPS problems, something it does very well. In normal usage I wouldn't bother with the A-GPS cache until you find it needs intervention.

Things like sharing photos come to mind. When I view a photo and click Share, the list can get pretty bloated depending on what apps I have installed. Is it possible to trim the list of apps down or disable them from appearing on this list? Annoyingly, many of my most useful and frequented apps have been bumped down on the list and I now have to scroll to select an app.

You might want to take a look at Andmade Share -- an app that claims to replace your share list with a completely customizable one, as the following screenshots show: As you see, you not only can get rid of unwanted entries -- but also re-organize the order of those left, so you can have your most-used on top.

I recently upgraded my clockworkmod recovery image to version 6.x and noticed that there's now a new blobs folder in the /sdcard/clockworkmod/ directory: <code> /sdcard/clockworkmod # ls -l drwxrwxrwx 3 root root 4096 Aug 27 14:46 backup drwxrwxrwx 2329 root root 131072 Aug 27 14:49 blobs /sdcard/clockworkmod # ls -l blobs/ drwxrwxrwx 2 root root 4096 Aug 27 14:48 000 drwxrwxrwx 2 root root 4096 Aug 27 14:48 001 [... 2322 folders omitted] drwxrwxrwx 2 root root 4096 Aug 27 14:48 ffc drwxrwxrwx 2 root root 4096 Aug 27 14:49 ffd </code> What are those blobs good for?
|
Starting with version 6, deduplication support has been built into clockworkmod recovery. The blobs directory folder contains a hashed directory structure that holds the deduplicated files across all backups. See the developer's Google+ post for more, in short: TL;DR: ClockworkMod Recovery now deduplicates files between builds. This results in way smaller backups. Don't delete /sdcard/clockworkmod/blobs

At the moment, I am using the standard video recording app for video recording. I have found that the recording automatically stops after just 1 hour. Is this a deliberate limitation placed on the app, or is this an android limitation? I have a 32Gb sd-card, so I don't think storage is a problem. I am using Android 2.2. I understand that this particular version of android has a 2.1Gb file size limit, but the videos I am recording are no where near 2.1Gb in file size. So what is causing the video to stop after just one hour is my real question.
|
Most video recording apps are IMHO limited to 1h non-stop recording, as you can find with a simple Google search, which is probably a safety measure to not let you run out of battery -- as video recording is the biggest consumer (see stackexchange-url ("What can I do to increase battery life on my Android device?")). However, a developer can have his app overriding this limit (see stackexchange-url ("Max duration for capture video on android") on Stack Overflow) -- so you might just have to find a video recording app which has this setting increased (as e.g. One Eye Browser in this linked pro-version).

They're most of the time baked right into the monolithic Linux kernel (or sometimes available as loadable .ko kernel modules located in /system/lib/modules/). Note: Linux kernel modules are build-specific and cannot be interchanged across devices, different firmware versions. See the Wikipedia entry for Linux kernel modules

As I have mentioned in the question, I want to transfer files (pics) from samsung galaxy S3 to HTC one x via NFC. I have switched on android beam on both the devices. When I bring the phones close, I am getting the "touch to beam" message on S3. When I touch it, I am getting a message that S beam is switched off, please switch it on. But I dont want Sbeam (as one x doesnt have it), instead I want the transfer to happen via Android beam.
|
As far as I know, you can't transfer files over Android beam, just URLs/locations etc. This is because Android Beam doesn't use Bluetooth or WiFi Direct in addition to the NFC transfer, which means that an average photo would take 30+ seconds to beam. In Android 4.1+ (Jelly Bean) you can transfer files with NFC+BT, and S Beam uses NFC+WiFi Direct.

While Android Enthusiasts is nice, it's still a very small site.

We'll reliable is somewhat subjective. But I can recommend App Brain ( Play Store App ) and App Aware ( Play Store App ). App Brain provides some additional features compared to the Play Store and App Aware allows you to follow app streams based on a topic (games, sw development, etc.). Both try to suggest you apps based on the apps that you have installed. And both are not a new app market, they just redirect you to the Play Store if you want to install a app.

I have a two-week-old Google/Asus Nexus 7 tablet, unrooted and otherwise standard. Yesterday it ran out of charge a lot faster than it usually does, and wouldn't seem to recharge. When it finally ran completely out of juice it shut down. Now when I turn it on, it gets stuck in an endless boot loop. I contacted Google's support and they're looking to send out a new item. However if I go that road, I'll lose the data on there. Has anyone experienced this issue? Is there anything else I could try? Thanks!

(EDIT) This answer is only really helpful for unlocked tablets.. Look after this paragraph if that is already the case. Otherwise read on. "fastboot oem unlock" also does a factory reset, you need to have it unlocked before you need it, alas. This is both good for privacy and bad for recovery from half-bricked devices... The factory reset does In fact a secure erase which nullifies all your data. According to Android: Building for devices : $ fastboot oem unlock The procedure must be confirmed on-screen, and deletes the user data for privacy reasons. It only needs to be run once. <code> $ fastboot boot recovery-clockwork-6.0.1.0-grouper.img downloading 'boot.img'... FAILED (remote: Bootloader is locked.) finished. total time: 0.020s $ fastboot oem unlock ... (bootloader) erasing userdata... (bootloader) erasing userdata done (bootloader) erasing cache... (bootloader) erasing cache done (bootloader) unlocking... (bootloader) Bootloader is unlocked now. OKAY [ 12.704s] finished. total time: 12.704s $ fastboot flash recovery recovery-clockwork-6.0.1.0-grouper.img sending 'recovery' (6480 KB)... OKAY [ 0.785s] writing 'recovery'... OKAY [ 0.225s] finished. total time: 1.010s # after that boot into the recovery (don't boot normal! it overwrites valuable data...) $ adb shell cat /dev/block/platform/sdhci-tegra.3/by-name/UDA \| gzip -1 -c \| uuencode bla | uudecode -o - | gunzip -dc | bar > /media/qnap/backup/n7.data.formatted.img </code> (END EDIT) You can boot a temporary custom recovery and create a backup of your device. It should also be possible to wipe it afterwards and recover from your problem without having to send it back at all (provided it's not a hardware issue). Steps: install the SDK (if not already done) and have working adb + fastboot executables ready Download a CWM recovery image from here unlock your Nexus 7's bootloader: <code> fastboot oem unlock </code> Here's how to enter the fastboot mode (the Nexus 7's codename is grouper ): Press Power for a second, and press Volume Down when the bootloader logo appears boot into a temporary CWM recovery: <code> fastboot boot recovery-clockwork-6.0.1.0-grouper.img </code> Create a nandroid/CWM backup from your broken installation (backup&restore-> backup) after the backup is complete, try to pull all data from your device: adb shell mount (should list something like /dev/block/mmcblk0p1 on /sdcard or so (not really sure however) adb pull /sdcard backup/ (replace /sdcard with the above noticed directory, this should extract all your data to backup/) check if everything is transmitted correctly) you can buy TitaniumBackup+ProKey afterwards (it allows extracting data from Nandroid backups quite easily) If that fails you can alternatively leech everything manually with adb: I assume you use Linux. . <code> #list available devices: adb shell ls /dev/block adb shell cat /proc/partitions #create images for each mtdblock #uuencoding is needed because the shell interferes with the stream (adds linefeeds or so): adb shell cat /dev/block/mtdblockX \| uuencode foo | uudecode -o mtdblockX.img adb shell cat /dev/block/mmcblkXXX \| uuencode foo | uudecode -o mmcblkXXX #compare md5sums: adb shell md5sum /dev/block/* md5sum mtdblock* mmcblk* # Look for reasonably sized images and what file system they are: ls -lh mtdblock* mmcblk* file mtdblock* mmcblk* # You should be able to mount those images now (if you happen to use linux): mount -t ext4 -oloop,ro mtdblockX /media/mtdblockX # Now use some file-explorer to access your saved data </code> Final step: If you are really sure that you got all your data back, boot back into the CWM recovery (see step above) and issue a wipe data/factory reset command. Then reboot and re-setup your tablet (hopefully you don't have a hardware issue). Optional step: relock your bootloader via <code> fastboot oem lock </code>

How can I get a wider LogCat output than the one from the terminal window? I also want to be able to pause the output so I can actually read something. My OS is Windows 7 X64.
|
Windows Its easier, what you can do is this, from the cmd window, <code> adb logcat > my_logcat.txt </code> and just let it run, now, you can pause, resume the scrolling, in that cmd window, same keystrokes for Linux terminal, IIRC, now launch an editor and open the file 'my_logcat.txt' and there the results will show, had there not being a pause/resume in the cmd window, the file will get updated, such as using ' notepad2 ', ' Notepad++ ' or similar, the in-built Windows's version of Notepad would do very little justice. Linux From a Linux terminal under a GUI such as KDE/Gnome, using the two utilities combined, found on most distributions, multitail , which is like a <code> tail </code> unix utility, only more powerful! <code> adb logcat # want to see the logcat on the screen </code> Using Ctrl+S to suspend, then Ctrl+Q to resume the display, and simply mouse scroll the terminal to back-track seeing the logcat output. The other way is this... <code> adb logcat > my_logcat.txt 2>&1 & multitail my_logcat.txt </code> The first line above creates a background process by using the <code> & </code> at the end of the command, redirecting any errors to <code> /dev/null </code> hence <code> 2>&1 </code> . As the process is forked into the background, using <code> multitail </code> can perform, scroll-back on the logcat.

I know I'm asking for the close-to-impossible -- as a real full-backup certainly requires root permissions. But still there are many folks around not wanting to root their devices -- afraid of voiding their warranties or bricking their devices, or just not having their devices supported by any rooting method. I also know there were a lot of questions asked already on this topic, and I checked all of them having the backup tag -- none covers the entire topic, all just have pieces, and especially people new to Android (but other non-power-users as well) would have a hard time figuring out the best way. So I want a detailed canonical answer to the question: Not involving root-solutions, how to achieve a backup as close as possible to a full backup ? Please do not give simple one-liner answers like "Use app xyz [full-stop]." If mentioning an app (and I doubt a single app would be the answer here), include what parts are covered by it -- as well as ideas on how to fill the gaps it leaves. (And to make it absolutely clear: I know the first thing coming to mind is Titanium Backup -- I use it myself, but this does not apply here: This question is strictly about methods for non-rooted devices! ) Moreover, the answer should be as generic as possible in terms of applying to a wide range of devices (i.e. it should not be resticted to one device or manufacturer). I already mentioned having investigated all questions here tagged backup . These will certainly be helpful providing details for answers here, so I will list up the topmost ones concerning my question: stackexchange-url ("How to backup an Android device?") stackexchange-url ("How do I perform a full pre-rooting backup of an Android phone?") stackexchange-url ("What info does Google backup?") stackexchange-url ("How can data on an unrooted phone be backed up?") stackexchange-url ("Could a non-root Android 4.0.3 smartphone's rom be backup?") stackexchange-url ("How do I back up (and restore) my phone before installing a custom ROM?") stackexchange-url ("Backup my Android without my Apps, Settings, Config's, etc.") All these provide some details for my question (so feel free to get inspired by them) -- but I feel there are still details missing. Also it would be helpful to have a summary -- say, an answer including the full description of "the maximum possible". A last criterium: While I'd consider cloud-based solutions ligit, I'd favour local solutions. If you can provide both: all the better. But some people value privacy quite high (I'm one of them), and thus would not trust their data to some cloud service. Thanks to Ryan, we now have a solution for a really complete backup of all apps and their data -- which I didn't dare to hope for! The only disadvantage: His solution only works for less than 10% of all Android users; namely those whose devices are running at least with Android 4.x . So again, I ask the close-to-impossible: Any solutions applyable at least on Gingerbread (2.3.x) or, better, even Froyo (2.2.x) -- so they cover the majority of current devices? These solutions may involve multiple tools (try to keep it as simple as possible though; think of your mother to follow your instructions ;) And keep in mind: NO ROOT! To further motivate high-quality answers (and hopefully avoid low-quality ones), I will be a harsh one here: As I rarely do, I will down-vote answers not fitting the mentioned criteria on one end -- but on the other end, I will setup a bounty for the best answer (which cannot be done immediately, but earliest after 2 days).

Solution Available for 4.x Devices: For 4.x devices there is a solution called "adb backup". This makes use of adb so you have to have the Android Software Development Kit (SDK) installed on your computer. NOTE: This solution will not back up and restore contact, SMS or calendar information The options for the adb command are: <code> adb backup [-f <file>] [-apk|-noapk] [-shared|-noshared] [-all] [-system|nosystem] [<packages...>] </code> -f : the path of the *.ab file that will be saved on your computer. This file is a compressed file that contains an archive of the data/apks from your device. -apk|-noapk : indicates if the *.apk files should be backed up (default is -noapk) -shared|-noshared: enable/disable backup of the device's shared storage / SD card contents (default is -noshared) -all : indicates that you want the entire system backed up. you can use the packages filter to just backup specific packages, or use -all for a full system backup. -system|-nosystem: indicates if all the system applications and data are included when backing up. (default is -system) <packages> : this is where you can list specific packages to backup. Use these if you want to back up only specific applications. If using -all, you do not need to specify packages. How to backup your device: From the command prompt you will need to be able to locate both the adb command and your backup file. The easiest way to do this is to run the adb command from the directory where adb is located. In Windows Explorer navigate to where you installed the Android SDK and <code> SHIFT+RIGHT CLICK </code> on the <code> platform-tools </code> folder. This will open a command prompt (your window will look different than mine). In Mac's Terminal you can type <code> cd </code> and then drag the folder platform-tools folder from finder to the terminal window and the path will be inserted. Hit and you will be in the right place. In Linux, I hope you know how to locate and cd to the parent directory of the adb command. You are using Linux after all. From here type the following command: Windows: <code> adb backup -apk -shared -all -system -f backup08262012.ab </code> Linux & Mac <code> ./adb backup -apk -shared -all -system -f backup08262012.ab ## Notice that -all doesn't mean ALL. See the big bold NOTE at the top of this answer. </code> (if you want to store the backup in a different directory, include a path for the ".ab" file as shown in the screenshot below.) You will then be prompted on your device for a password (this is used to encrypt the backup): To restore, it works almost the same way. Windows: <code> adb restore backup08262012.ab </code> Linux & Mac <code> ./adb restore backup08262012.ab </code> Then you will be prompted for your password to restore on the device: Now for the shameless self promotion: Droid Explorer (v0.8.8.7+) will be able to handle this for 4.x devices. While Droid Explorer is currently optimized for Rooted devices, this functionality will work for non-rooted devices as well. Droid Explorer will do full backups of the device and save them in <code> %USERPROFILE%\Android Backups\ </code> . Within that folder is a folder named for the device, and inside that folder are the backups. Double clicking on the Android Backup file will allow you to restore your device from the backup file.

I know you can turn off notifications from the native email client , but is there a way to turn them off for Gmail, Google+, and other Google apps? I have my Google account set up on my phone, which is useful, but if I can't specifically turn off Google notifications I'm going to have to unsync it, because as it stands I have to either silence all notifications and miss important text messages, or get woken up by G+ comments and NYT emails at 4 AM.
|
To turn off notifications for Google+, open the Google+ app, press Menu-> Settings-> Notifications , then press the ON/OFF toggle in the top right. To turn off notifications for Gmail/Google Apps Mail, open the Gmail app, press Menu-> Settings , select the account you wish to disable notifications for, uncheck the checkbox that says: Email notifications To turn off notifications for Google Talk, open the Google Talk app, press Menu-> Settings , select the account you wish to disable notifications for, press IM notifications and select off , and the same for Video chat notifications To turn off notifications for Google Voice, open the Google Voice app, press Menu-> Settings-> Sync and notifications , and uncheck the boxes for text and voicemail notifications. NOTE: This is based on Android 4.0+, some of these apps (especially Google Talk) may function differently on pre-ICS.

I am a new Android user, and recently I have upgraded the default ROM of Samsung Galaxy S 3 to Jelly Bean MIUI ROM using the steps mentioned at the International Business Times . Now I want to revert it back to default ROM but I am unable to do so. Although the blog says If you want to return to your previous ROM for some reason, boot into recovery (using the procedure explained in step 3), choose backup and restore, then restore your previous ROM by selecting it from the list. But I didn't find anything within the list. I tried wipe data / factory reset but still not getting the default ROM. What do I need to do to get back the default firmware?
|
I found a workaround, Downloaded a firmware from http://www.sammobile.com/firmware/ and updated my galaxy s3 with that using odin. Upon first reboot my phone hangs showing only boot screen with samsung logo for about 2 hours, then I restarted phone in clockworkmod recovery did a wipe data / factory reset and then restarted the phone again, I got the default firmware back. Then connected the phone to pc using kies and upgraded the firmware.

I've created 2 folders on the root of the SD card, Ringtones Notifications and placed one mp3 file within each. When I disconnect the DroidX from the USB cable and navigate to either "Settings" > "Sound"> "Phone ringtone", or "Settings" > "Sound" > "Notification ringtone", neither mp3 file shows up. What am I doing wrong?
|
You don't need to make your own folders. The proper file to put the mp3s is /system/media/audio/ - where you will find folders for /alarms , /notifications , and /ringtones There are two things to keep in mind when doing this: If you are using full-sized .mp3's , you will put considerable strain on the system when it comes time to load one. In my experience, two minutes of mp3 works fine for an alarm, but such a file takes a few seconds to load, and will not make for a suitable ringtone, unless you trim the file first. You will have to re-do this every time you flash a new ROM. An alternative to this -- is to have them in /sdcard/media/ -- But if you have an older device, having them in the root directory allows for better performance. HTH!

I have thousands upon thousands of text/picture messages on my Samsung Galaxy S 2, ice cream sandwich. When I go to open a conversation, the phone stops for a good 30 seconds, even after a fresh reboot. I don't want to delete my messages, but I'm sure if I could somehow limit it to, say, the last 100 messages by default, it would load much quicker. Again, I don't want to delete them, and I still need access to most of the messages, but only on demand
|
Try using an alternative to the stock SMS app like Handcent SMS. A cautionary note - turn off the auto delete option (the option to auto delete messages older than X days). An additional note - since your SMS store seems quite precious to you, I'd also recommend SMS Backup & Restore . It can backup your SMS at scheduled intervals and also email / upload them to Dropbox if need be.

I haven't found any good solution for managing files on my Galaxy S2 from Win7. I've tested Kies and some other software but I'd like to be able to move files, create directories etc. through file explorer in Windows. There was some talks about installing a server also but it feels like using nukes on a mosquito. Preferably a free software that I can install? Frankly, I was expecting that a simple connection via BT would suffice in this era of Plug & Play but, apparently, in my case, it's Plug & Prey, instead...

I have powered down my new Nexus on a couple of occasions now, but it will not boot up subsequently UNLESS it is plugged into the charger. Is this by design? I've also had it go into this unresponsive state after being charged overnight; in that case, I turned the charger off and on again and it was OK. Anyone had this happen to them? Do I have a faulty unit?

When the phone's battery reaches ~20%, I get the message to connect my charger on the lock screen. Is there a way to lower the threshold for the notification -- similar to the setting for a laptop? For clarity, I want to change the settings so that the "Connect your charger" message appears when my battery is at 5%, instead of its current threshold, ~20%. I should mention that I'm looking for a setting that's on the phone, without the need to modify back-end files. Also, I've actually gone through the whole settings section looking for the option and didn't find anything. Hopefully, I didn't overlook it.
|
There is no setting available in any Android ROM that has the battery threshold setting. From the previous stackexchange-url ("answer") given, it is built in. Only course of option is to roll your own Android build, with the hard-coded value adjusted, but, and is a big but indeed, it is not the recommended route to take, as the code behind Android to handle the battery mechanism varies from chip-set to chip-set and to each and their own manufacturer. By adjusting it, there could be invariable damage to the battery as a result, since the threshold is specified, by "tweaking" it could affect the battery in the long run and possibly end up shortening the battery life also.

What happens is that every time I reboot the phone, the rightmost app shortcut / widget / icon that I place in the app drawer keeps disappearing. I can replace the icon and it stays there, but only as long as I don't reboot the phone. Why is this happening and / or how can I solve it?

It seems there is a further update to the Xperia Mini Pro, probably 9.1 is way to go, might fix up that known issue. Check on the CyanogenMod page for Xperia Mini Pro .

Currently Google Now notifies me 10 minutes before I need to leave the house for an appointment (taking traffic into consideration). How do I change the notification time to some other value?
|
The default reminder time is actually based on your calendar. If you open your calendar, open Settings, and select General settings, "Default reminder time" is near the bottom (I'm working from Cyanogenmod 10, but AOSP/Nexus devices should be similar). This controls the general notification time. The Now functionality is separate, and (from what I understand) is based entirely on travel time. If your appointment has a destination that Google recognizes, it will calculate travel time and pop up a card far enough ahead to allow you to meet that travel time and arrive on time. I'm not positive if it factors in your reminder time into this or not, but it's possible that it is. If that's the case, it will notify you 10 minutes + travel time currently, and if you modify the calendar notification time, it should modify the Now notification time. Again, this is speculation based on how I understand Now to function, but I believe it's fairly accurate based on my experience.

Background Android has specific rules regarding the installation of applications and their physical location. It works like and hierarchical structure: If the app has a specified location by the developer, this takes priority. If it is not specified in the app, then the default install location is used. Android has 3 identifiers for app storage location: that may be mentioned on the application manifest android:installLocation : "internalOnly": The application must be installed on the internal device storage only. If this is set, the application will never be installed on the external storage. If the internal storage is full, then the system will not install the application. "auto": The application may be installed on the external storage, but the system will install the application on the internal storage by default. If the internal storage is full, then the system will install it on the external storage. "preferExternal": The application prefers to be installed on the external storage (SD card). There is no guarantee that the system will honor this request. The application might be installed on internal storage if the external media is unavailable or full, or if the application uses the forward-locking mechanism (not supported on external storage). Old applications may have no choice but to install on the internal storage, as per the Google Documentation : The ability for your application to install on the external storage is a feature available only on devices running API Level 8 (Android 2.2) or greater. Existing applications that were built prior to API Level 8 will always install on the internal storage and cannot be moved to the external storage (even on devices with API Level 8). What can I do? You can manage the installed applications and set their storage location, all from one place: Tap "home" to return to your device home screen; Tap your device "menu" button; Depending on your device, you either have to: Tap "Manage apps"; Tap "Settings" > "Applications" > "Manage applications". Now access the third tab where it reads "USB Storage" or "On SD card" (again, varies with the device); Here are listed all the applications that are allowed to be moved to your External Storage, tab over one to bring up more options about it; When the application details panel opens, you have a button "Move to SD card", use it to move that application to your External Storage; Press "back" to return to the list. If you've moved the app to the external memory, you will notice that a green tick is present on the right side on the list, to let you know that the application file is currently on your External Storage. This is a safe guide to have your OS managing the applications and moving then from Internal Storage to External Storage without hacks or tricks. You can read all about it on the Google Official Documentation .

So recently bought an Android tablet, having first had an iPhone. So with Apple's strategy, apps seem quite restricted. They can really only do a couple of minor things outside of the app (like notifications etc.) and they're also reviewed by Apple. Android seems to allow a lot more freedom. You have apps that change the keyboard, or change the start up screen or allow you to share across apps etc. So my question is... if I install something from Play Store, do I know that it will always uninstall properly? Do app developers actually need to write an uninstall program or is this done automatically in the OS?
|
Short answer Generally, apps are cleanly uninstalled, and most if not all of their data will be removed along. Some exceptions may however apply to their data stored on sdcard, if any. Detailed answer Android uses a data structure which is defined by the developers API, and developers should stick to it. There are also not too many ways they could deviate, as e.g. file system permissions prevent this. Aside from the <code> .apk </code> (the app itself) installed at a defined place, there are also defined places for the apps data: All these can only go below <code> /data/data/<package_name> </code> on internal storage (rare chances an app can access other places in internal storage to place its data, except from some "temporary" or cache locations. As for the sdcard, the API strongly recommends to use <code> Android/data/<package_name> </code> as corresponding place (see API documentation). As long as developers stick to these rules, uninstalling the app will also remove all its data (as the system takes care for all those locations defined by the developer documentation, since these are easily identified via the package name). However, on the sdcard there are almost no restrictions which places an app can access (which is due to the FAT file system used for these cards), and some apps go wild here.

I read a lot about rooting android, that it is risky, that I can mess all and get my device completely dead and nothing can be done about it. So my question -- why all these phones can't be just mounted? If I mess up my system with root, I always can boot with live-cd or write disk image directly to <code> /dev/sda </code> . After all, I can just mount broken system and repair it. Why android to not support it? Is it some real technical restriction, related to flash memory or something, that differs between phone and PC/Notebook?
|
The only reason you need to root phones in the first place is that the manufacturer has tried to prevent software choice on the phone platform. The PC design is pretty unique in that it has had a choice of software platform for so long that it's an ingrained feature, although with Secure Boot on Windows 8 devices this is likely on the way out.

When I plug a headphone into my Nexus' audio port, the headphones simply don't play any sounds or music. The device seems to detect them, because the built-in sound output stops working. I tried it with another headphone and it didn't work either. There is no error log output. It really sucks, because I can't hear any music. How can I solve it? (Galaxy Nexus with stock Jelly Bean)
|
I own an OG Droid and a Droid Bionic and both phones eventually had similar audio jack problems. On one phone I found the issue to be a wad of dust crammed in the jack which I had to fish out with a [enter your choice of small pointy tool]. It could be a result of the internal contact points being pushed back from repeated tension. This would weaken the contact with the audio cable. In your particular case I don't think this is true however. Other things you can try: Pull the audio cable in and out several times wiggling it and testing it. (Ideally you'd want to test it with something that plays audio continuously so you don't have to keep hitting play) Getting a different and potentially better quality audio cable to test with. You can also try resetting to factory default which may help if the problem is software related. (As long as you have a google account synced with your phone, all your apps will be automatically re-downloaded) If all else fails, take it back to the phone manufacturer or your phone service provider. They should be able to fix it for a reasonable price. There is the option of trying to fix it yourself but that isn't recommended if you are uncomfortable working with small/delicate electronics, not to mention voiding your warranty.

The device has a direct connection and does not requires insertion of a SIM card. I can connect it to my Laptop and use the internet service, but it is not possible to connect it to the mobile phone.

I just upgraded to Android 4.1.1 Jelly Bean and I was wondering if syncing my Facebook contacts could mess up my Google Contacts ( which are very well organized compared to facebook ), or if both services do keep isolated from each other.
|
No, they are run completely separate and exclusive from each other, not something that'll completely replace the data within your existing contacts... Although they can be merged so that it displays one contact instead of two (again, it still won't physically combine the data). That way, you can have their profile pic as a contact icon and even their birthday, phone number, email in one place if they have it on their profile. It'll try to merge automatically if the name + phone number or email from your Google contact matches what they have in Facebook, but it'll have to be manually merged if it doesn't.

In the Google Play Store, when an app is too large in size, a "WiFi" tag is mentioned next to the app name. That way the user can know that the download is heavy. At what application size does Android add the WiFi tag to apps ?
|
Good question. I believe the answer has been recently changing, because while I was initially under the same impression as SaintWacko (thinking the cutoff was 25 MB) I have been unable to find any Google documentation defining such a limit. What I have found is that the maximum APK (app) size is 50 MB. Developers can also choose to use up to two APK expansion files to be downloaded along with with the app's APK, each of which can be up to 2 GB. Even for these larger expansion files, though, I could find no mention of Wi-Fi only download restrictions (unless explicitly required by the developer). I remember seeing the Wi-Fi download flag you mention on some larger apps that I use personally, but today I've gone back to those same apps and don't see that flag. As best I can tell this policy has changed.

My HTC One V (on 4.0 ICS) seems to be continuously downloading something even when it's inactive, and it's using the battery abnormally fast. My data usage graph: (click to enlarge) On the first picture, the brown line is for the "Android OS" element, which as you can see is responsible for at least 60% of the data consumption. I don't know what Android is downloading, but it does it continuously and it has a big effect on my battery's life. When I disable mobile data, the battery usage line becomes flat (see second picture). How can I check what exactly "Android OS" is doing? And how can I disable this activity? Here is the battery usage graph. As you can see, the line became flat when I've disabled mobile data. (click to enlarge)

I just released my first app not too long ago. To test it in the Play store, I installed my own app. After discovering some bugs, I uninstalled it, and installed the one I would code to fix from Eclipse. After fixing the bug, I post an update and re-install my own app from the store to test it out again. If I keep repeating this process (uninstalling and re-installing my own app from Google Play every time I release a new version), will my app's rating be degraded? Should I strictly stick to using my own app by installing the raw version (not the one on Google Play, but the one I built in Eclipse)? Thanks.
|
As far as I know, this should in no affect your app's rating. This is something I do myself constantly with testing of my own apps. The only thing that will ultimately affect your rating are the number of stars your users give you. Yes, you can rate your own app, but you can only do it once. Uninstalling/re-installing shouldn't change your own rating to your own app either.

I would like to take an installed app, including its data, from a rooted Android device and produce from it an APK suitable for installing on a non-rooted Android device. Is this possible? Edit: Existing answers/comments seem to reinforce the idea that existing apps do not support embedding an app's data within an APK. Perhaps the more fundamental question is, can an APK embed files destined for <code> /data/data/[appname] </code> , or are they restricted to being self-contained when installed? Notes: I assumed that, if it were possible, this functionality would be built into an app such as Titanium Backup. Titanium Backup can back up app+data to a single file, but that file is not an APK and can only be restored by Titanium Backup itself - which is no help for me as the destination device is not rooted and so cannot run TB. Solutions that require use of the terminal on the phone or ADB are fine. Thanks.
|
Having now read more about the APK file format, I think I can now safely answer my own question with "it's impossible". An APK file does not contain a data structure which is "unpacked" on install like the packages used by, for example, most Linux distributions. Instead, an APK is simply a self-contained, rebadged JAR file that contains the application's bytecode, manifest and certificate and nothing else. The contents of <code> /data/data/[appname] </code> are presumably created by the application code when it is first run (or at some future point), and there is no way of embedding such data into an APK so that the system automatically moves it to the correct destination at install time.

As an owner of a Nexus One running Gingerbread, I'm continually fighting to keep free space in my phone's Internal Storage. Today, I noticed something odd. The bottom of Andorid's "Manage applications" screen shows a bar graph that reports the phone's "Internal storage" (I have 29M free). When I click into an app, I can see storage for the "Application", and for the app's "Data". The application, in most cases, is stored on the SD Card. The application's "data" is stored on the phone (I presume). What I'm finding is that I'm not seeing the whole picture of what is taking up Internal Storage. For example, I have 29M free in Internal Storage. The Angry Birds app, which is stored on the SD card, is 3.14M. It's Data is 4.0K. I then delete the Angry Birds (gasp!), and my free Internal Storage jumps up to 31M. So it looks like it's freed up 2M, when I only would have expected it to free up 4.0K. Any idea what's going on here?

The free space difference can be accounted by three relevant factors that may end up giving you some misleading information about the real space available on your internal storage: The Free space reported The free space reported at the end of the "Manage Applications" screen is rounded to MB, and it gives you a general free space estimation based on the moment you opened said screen, and it gets updated from time to time (by my tests about every minute). I've mentioned "rounded" because if you access the "Storage Settings" panel, you'll get a clear picture regarding the free space available, down to KB. The App Allocation As already mentioned by t0mm13b, an application may be entirely moved to the SDCard or leave a portion behind, this issue is more related with the development of the application itself and there's no standard rules to follow. I've performed an exercise with "Angry Birds", and while the download mentioned 20MB, after installed it consumed 24MB. After moving it to the SDCard using the option for this end under "Manage Applications" screen, 1.85MB were left behind on the Internal Storage, plus 4KB of data. Temporary System Files from other applications or running services While I was writing this answer, the free space reported varied between 2MB, this tells us that the OS is constantly creating and freeing up space depending on the stuff running. There may exist other factors that concern the ext4 File System specifications used by Gingerbread , but I don't believe they better account for the 2MB difference. By the three points mentioned above, while performing an exercise with the application you've mentioned using a device with a stock Gingerbread ROM, I've managed to account for 2MB of difference, just like the space you've mentioned. Determine Internal and External Space Occupied Following up on the comments, regarding a way to accurately know how much an app occupies on the device, and being able to view it by external or internal storage, the most accurate application I'm currently using is SanDisk Memory Zone by SanDisk Corp. available for free from Google Play Store. Open the application Select the desired storage Check the details about it

I'm trying to restore a new device with apps from my old device, but neither Android Market nor AppBrain seems to automatically bulk install them? When I use the Execute method in AppBrain it seems to only send me to manual install of all apps, which probably would take a long time since I use a number of apps. Is there some way to make AppBrain bulk install a list in a batch or is it possible to move the apps from my old device to the new one?
|
Assuming you've previously installed AppBrain and synced your device, you can do the following: From Google Play Market download and install AppBrain and Fast Web Installer apps. Open the Fast Web Installer and sign in with your Google account (same one you are using on Play Store). Open the AppBrain app, and sign in with your AppBrain account. Go to Preferences, and then use the "Enable Fast Web Install" option. Under Menu go to "More lists..." option, select the previously synced list, tap the "Add all apps" button, and tap the back button. Tap the "Execute" button, and after reviewing the permissions tap the "Install" button. This should download and install apps in batch, without having to confirm each one separately. You can also create lists of apps via AppBrain's site, and these lists should show up in the app.

I want to learn a language or prepare for an exam with the help of my Android phone or tablet. Are there any efficient and fun methods out there to do so?
|
I could list up a bunch of stuff here now, but that would get quite long. So let's better organize it by groups: Covering multiple topics First, of course, there are mentioned Flashcard apps (best-rated here are probably Learn Easy and AnyMemo -- a longer List can be found at my AndroidPIT overview Vokabeln & FlashCards (Google Translate version here). These are not only restricted to languages, as mentioned AnyMemo shows 1 : being able to also use images, you can use it for everything -- think e.g. of images of molecules, electronic wiring examples, and others. Languages Second, there are the "big language guides " -- again I can refer to an overview at AndroidPIT: Sprachführer (and the Google Translate variant here). Though this latter mainly addresses German native speakers, the end of the list has some generic hints. While FlashCards & Co focus on learning words, the more complex language guides also cover grammar and complete phrases. I guess best is to use a combination. As for the FlashCards, any solution should do: they are mostly not language specific. Other with the language guides, where it lies in the nature of this type that it has to be specific at least to the target language you want to learn. Examples here include French Class Demo 3 and Italian in a Month Free 4 . A third category should not be forgotten to mention here: Get yourself a good eBook Reader , and add some books to it which are written in the language you want to learn. I recommend Moon+ Reader 5 here, which already includes a huge Online Library list for multiple languages (which actually is sorted by languages even), so the reader immediately has some ressources at hand. Having trouble with some words while reading? Simply long-tap the word to open a dictionary -- either online translation, or an offline dictionary like Fora or ColorDict 6 , which both can deal with StarDict files saved on the sd card. Being able to mark and even annotate with Moon+ Reader (see the picture 5 ), one could also use this app for other subjects/classes. Number four now should be obvious: There's that Youtube app one could check some language specific movie[clip]s with. Or get some other movie player (MoboPlayer probably being a good choice), plus some videos in the targeted language. Guess number 5? Right: Music . There are plenty of music players around, and songs to pick. Repeating them over and over is baking some phrases to ones brains :) Beside this fact, there are also some audio books and language-learning audio files around. Science So far on language-learning -- but your question was not restricted to that, as I just notice. So let's go for some more possibilities -- pointed out in the AP overview Formelsammlungen & Referenzen (Google Translate: formulas & references ). There are tons of references for chemistry, like e.g. the very famous Merck PTE HD (periodic table) 7 , mathematics calculation helpers and references like e.g. Mathematics 8 , physics references, electronics, stuff for engineers... So learning is clearly not restricted to languages. School Organizers Learning for school or study? Multiple subjects to cover, and courses to keep track of? This also can be covered using your Android smartphone or tablet. The AP overview dealing with this would be Stundenpläne und Schul-Organizer (Google Translate: school organizers ). From simple timetables like School Schedule 9 to just keep track of what subject is running when and where, to apps also keeping track of related tasks and even silence the device during classes (e.g. My Class Schedule -- note the tiny numbered boxes on the blue items in the screenshot 10 , which indicate connected tasks), you can find many solutions. Summary To sum up: There's a lot of stuff you can pre-load to your tablet -- and then use to learn on-the-go.

My Nexus 7 seems to have poorer Wi-Fi reception than my iPad (1st generation). At home it is always able to reach the router, so not an issue. Occasionally when I am out the iPad will have reception when the Nexus 7 doesn't. I was looking inside the back cover, and it appears there are a few antenna built into the cover. I am curious if the Wi-Fi antena is in the back cover, and if there is some way I could boost it by attaching an external perhaps.
|
iFixit has a Teardown that shows the Wi-Fi antenna is on the back. Interestingly, when I took it off and looked I saw that it was nicely labeled too. Also, the Wi-Fi reception seems much better after reattaching the cover. Maybe my Antenna wasn't connected very well. It appears a simple mod could be done to attach an external Wi-Fi antenna if I needed to do that. A mod may be in my future.

In most cases where the keyboard is needed, it pops up automatically. However, I am trying to play Dungeon Crawl Stone Soup Webtiles on my tablet, and it does not bring up the keyboard. Is there any way to bring it up manually? I'm on a Nexus 7, running Jelly Bean. Ideally, there would be something that did not show up on the status bar, but sat in the notification drawer, and I could tap that to bring up the keyboard. Actually, even better would be something that sat down in the bottom, next to the navigation controls, but I don't believe that's possible without modifying the framework.
|
As I see an alternative keyboard may solve your issue, and this seems to be an acceptable solution, and you even mention something you cannot find -- hereby I proudly present: Hacker's Keyboard Checking its Guide, there's in fact a section suggesting such a feature: You can configure the gesture used for this in the keyboard's "Gesture and key actions" settings menu. If the swipe action is too hard to trigger, try binding the "close keyboard" action to the "Volume down" hardware key. This won't interfere with normal use of the volume button while the keyboard is closed. Though this applies to "close": If there are gestures you can configure, it might as well be able to have one for "open". The FAQ may reveal some more clues. SaintWacko notes in the comments: To be able to open it anywhere, you go into the settings for the keyboard and check the box for 'permanent notification'. It will then keep an entry in the notifications which you can tap to bring up the keyboard at any point. So this would be an alternative possibility -- the hook being it is hooked to this special keyboard.

I keep getting "phone storage is getting low" constantly even though I've removed almost all the apps I've installed. Is there a way to look in the phone storage to see what are the contents? Google Talk and Facebook fail to function because of this. I have a Sony Ericsson Xperia Arc running Android 2.3 (Build 4.0.2.A.0.62)
|
Maybe because you haven't removed only the small apps that doesn't take significant space. Go to settings -> Apps -> Select "All" on apps tab -> Click menu and click sort by size. You'll see the apps sorted by the size it takes on your phone. Check if the top apps in this list are taking most of your space.

I have recently rooted my Samsung Galaxy Y phone and installed the Titanium Backup (free version). Anyhow, I am not satisfied with it as many of the features are unavailable and I am asked to get the paid version. My Question is: Are there any free alternatives to the services offered in Titanium Backup Pro? I am in particular looking for the "Convert to user app" and "Enable 'multiple profiles' for this app" features.
|
I'm not aware of a full-blown replacement for Titanium Backup, but there are solutions for the specific functions you're after: Recent versions of Link2SD can convert user apps to system apps and vice versa (available on Google Play). SwitchMe offers a solution for switching among multiple user profiles (available on Google Play). The free version is limited to two profiles and "no security features".

I cannot check you image (corporate proxy forbids), but I take it you mean those "toggle buttons" to switch on/off things like Wifi, Bluetooth, etc. In this case, you can do so e.g. with Elixier (first picture 1 ) or Notification Toggle (second picture 2 ) Some Custom ROMs also come with something similar pre-installed, as e.g. CyanogenMod does.

I have a TV that runs android 2.2. It can take a USB mouse and keyboard, and I'm running the dolphin web browser on an auto-refreshed page for digital signage. Only thing is, I can't get it to zoom in or out - there is no touch (so multitouch doesn't work), and there are no +/- buttons as tehre are on some stock browsers. The stock browser doesn't work on the site in questions, and firefox won't load onto the device (it has a MIPS processor, so any app using the native SDK won't work). Any ideas?
|
Purchase a mouse which supports multitouch gestures (using which you zoom in or out). e.g. PadKite If you don't want to purchase anything, just go to Dolphin's <code> Settings </code> , tap <code> Lab </code> and turn ON <code> pinch-Zoom Button </code> . Then, you'll find +/- clickable buttons to zoom in or out.

I have been following this guide to root my Samsung Galaxy S smartphone. I've followed it to the letter, but after I load the new kernel to the phone, the phone gets stuck in a boot loop. The phone restarts after the kernel is loaded, it gets to the "Galaxy S" splashscreen, and then it goes off and restarts. Nothing else happens. I have tried to get in to the recovery mode by holding the power, home and volume up button, and all this seems to do is hang the phone when it displays the same splashscreen. It does nothing else. I'm really stuck, I've tried reloading the kernel several times since but nothing happens (I can get in to Download mode). I've also read on another forum that you can press the power button and the volume up and down buttons, but these don't do anything. Many thanks for the help!
|
Edit Honestly, I am not 100% sure that this was really a problem related to the kernel. I think that the "problem" could be also caused by the fact that pressing the home key in recovery mode results in a reboot. The correct way to select a recovery item is to press the power button. Original post I had the same issue two days ago. The problem was the kernel. After switching to the kernel that was mentioned a few wiki changes before it worked like a charm. Kernel: http://cmw.22aaf3.com/aries/gt-i9000/root/Hardcore-speedmod-i9000.zip MD5: afccda1f4efb560398dd5bc107bb7a69 I even (re-)added this information but it was again reverted. :-(

I have a rooted Nexus 7 Jelly Bean tablet and whenever I attempt to run an application from a terminal emulator app after chmod 777ing it and using the syntax ("./applicationName") it insists that I do not have permission to execute even though I granted my self superUser privs using ("su"). After that I did a little research and I learnt that if you copy the file to the (/data/local/temp/) directory you should be able to execute the application. So when I tried that it said that the file does not exist even though it shows up when listing the directory contents using ("ls") I have no idea what steps to take, if it helps I am tried to run (scp) as a test but I wish to be able to run a custom compiled version of dns2tcp. I know I could have used better applications such as a hello world compiled natively onthe device but i couldnt get my hands on a C compiler for android such as gcc. Thanks for any advice

In this case I'm looking to restore SMS messages from Titanium. I have made a backup of all SMS. Then I started on a new ROM without restoring SMS. I then made a new backup of the current SMS. Is it possible to combine those two separate backups so that when I restore I will get my SMS from both backups? As I understand, if I restore one backup, then I restore another backup it will not combine them but rather write one over the other.
|
This is more like a manual job, but can be done. With Titanium Backup PRO/Donate version, you have this feature (compare versions here): Backup/restore SMS, MMS, call log, bookmarks and Wi-Fi networks in the portable XML format! You can combine both SMS backups into a single XML file format and restore it to your phone all in one. Afterwards, perform a backup like you usually do, to have it all together. Ps: Will probably require you to go back and forward, but here's a guide: Backup to XML the existent SMS on your device; Restore the old SMS to the device; backup the old SMS to XML; Edit both XML files to merge them; Restore all back to your device. You can refer to Titanium Backup website to collect more information or to request support from the developers.

I need to make international landline/mobile calls. My laptop with Debian is failing me here and iPad failing stackexchange-url ("here"). I want to use Google Voice because it is far cheaper than my local carriers. I tried to use their marketed Google Voice -mobile but for some reason it seems to turn into my carrier -version of "phone" or actually I am not sure whether it is the right version. I am looking for the same Google Voice as in Desktop: you open up Gmail and then there type the number to make cheap calls to which you pay through your Google Wallet. So how can I call, using Google Voice and Google Wallet, in my Android -phone?
|
Yes you can! Check up this answer about Talkatone stackexchange-url ("here"), it is based on Google Voice. The sound -quality is not the best but I like the idea that I actually need just a WIFI to make cheap international calls. I have actually replaced my landline/mobile/local -phones vith Google-Voice because it is much more convenient to pay to it through credit card and much more convient than carrying a massive amount of PrePaid/Post-paid -cards when travelling-or-just-living-well-and-free-etc, highly recommended tool indeed! Talkatone in iPad is a killer, a bit like FaceTime but integrated to Facebook and probaly to other services in the future. Talkatone in Android is similar, good integration so saving time in toning all contacts from Google Contacts, FB Contacts, etc. If you are a buz, you can imagine how much time this will save -- you need less to worry about crazy international -phone charges and you can actually drop out mobile-phone -contracts altogether, just charge employers with Google Wallet/Voice! Talkatone has poor sound -quality because it wants to sell its Premium service but if ads and a bit poorer sound quality do not matter, it has worked for me, nicely (haven't tried the Premium -service). A good/bad side is that your number is some oddity but extremely good side is that you do not need to know the prefix with internatinal calls in using Google Voice, super convenient! -Sim-card? -Yes you don't need a SIM -card to make international calls, just WIFI. Phone does not require SIM -card, dot. Victory :)

My best guess as of now is "partition and mount point layout". But it feels like there's more to it, since the bootloader can identify the HBOOT by name. I've been flashing custom ROMs for quite a while now, but I still haven't quite grasped what HBOOT really is or means.
|
HBOOT is bootloader. It lives inside NAND's first partition, mtd0 (if partition map is MTD). It is loaded in memory (RAM) when device is switched ON. Its jobs are: Check the Hardware. Initialize the Hardware. Start the Operating System (Either Android or Recovery). HBOOT can also support doing more than this like flashing ROMs. Something More: Nandroid backup and restore don't touch HBOOT.

Someone suggested a pay-for app in another question and when I looked it up, it seemed it didn't have any trial version that has the feature for which I'd pay. Now, I will not pay for something I have never seen working, even if it's only 4€ and so I was wondering whether I missed something or whether it's usual for pay-for apps to charge before you even can try it? (This app, Moon+ Reader, does have a free version, but I'm specifically interested in a feature of the pay-for version, so the limited free version doesn't help.) It seems like a very long time (maybe never) that I payed for any software on my desktop where there wasn't a demo of some sort to try out the key features you payed for.
|
You get 15 minutes trial of all paid apps listed in Play Store. Its Google's policy to refund money if you aren't satisfied but you'll have to claim refund within 15 minutes. After purchasing an app, just look for <code> Refund </code> button on app page in Play Store app.

I've just bought a Nexus 7. When I plugged it into my laptop, it shows the media folder, I'd like to access the sdcard folder just like the other devices. How to transfer files? I think "adb push" is not a good choice.
|
Nexus 7 doesn't support UMS (USB Mass Storage) out of box. But, it supports file transfer by MTP (Media Transfer Protocol). MTP allows you to push and pull any type of files from sdcard, but it doesn't allow you to edit files directly on sdcard (like you do with UMS mode). From your screenshot, it looks like your Nexus 7 is connected with PTP (Photo Transfer Protocol), also known as Camera Mode. Switch to MTP mode and do whatever you want. Also make sure your PC OS supports MTP.

I've found an application called Silent Time, which allows me to schedule when my phone needs to go into silent mode, and when it needs to come out of it. It's a start, but I'm looking for something a bit more extended. This is what I'd like; Monday, tuesday, thursday 06:45 Airplane mode OFF Silent mode OFF Data traffic (3G) ON 08:20 Silent mode ON 11:55 Silent mode OFF 12:45 Silent mode ON 16:15 Silent mode OFF 17:00 Wifi ON Data traffic OFF 22:00 Wifi OFF Airplane mode ON Silent mode ON Wednesday 06:45 Airplane mode OFF Silent mode OFF Data traffic (3G) ON 08:20 Silent mode ON 11:55 Silent mode OFF 12:45 Wifi ON Data traffic OFF 22:00 Wifi OFF Airplane mode ON Silent mode ON Friday 06:45 Airplane mode OFF Silent mode OFF Data traffic (3G) ON 08:20 Silent mode ON 11:55 Silent mode OFF 12:45 Silent mode ON 16:15 Silent mode OFF 17:00 Wifi ON Data traffic OFF 22:00 Wifi OFF Silent mode ON 23:45 Airplane mode ON Saturday 09:30 Airplane mode OFF Silent mode OFF Wifi ON 23:45 Airplane mode ON Silent mode ON Sunday 09:30 Airplane mode OFF Silent mode OFF Wifi ON 22:00 Airplane mode ON Silent mode ON When I say OFF or ON it actually needs to do that, and not just switch it, so that I can switch manually without disturbing the schedule. I need to be able to pause the schedule at any time. Being able to add exceptions (days on which to interupt the schedule) in advance would be nice, but is not required. Is there any app or hidden feature for Android which would allow me to do this?

Phone Schedule <code> Switch network, modes, volume, WiFi, BT, Ringtone, Brightness, More on schedule! All-in-one scheduler for your phone: !NEW: Mobile Data On/Off - a feature everyone's been waiting for! (*read more below*) !NEW: Reminder. - Brightness! (Auto, Full, Custom, Dim Screen) - Launch an app. (launch your internet radio to make music alarm) - Silent mode, vibration mode, volumes(ringer, media, alarm) - Bluetooth and WiFi ON and OFF - Airplane Mode - Change Ringtone and notification tone, Silent Ringtone And more! Create a task once and it will execute automatically. Configure time and days of week when you want it to repeat. Morning, daytime, night, weekdays, weekends, you name it! Save battery by switching off unused functions when you don't need them. ***About Mobile Data*** Mobile data is available on all supported Android versions. I have tested it on Nexus One and Samsung Galaxy Nexus. However it may not work on some phone models, i.e. on HTC EVO 4G Mobile Data Off works, but On - doesn't. I'm very sorry if this function doesn't work on your device, very often manufacturers block this and there's nothing i can do about it :( Phone Schedule is a tool that allows you to create a list of tasks, which you want to automatically run at specific times. For example, you might want to switch your phone to silent mode when you go to bed, so you add a task, set time to 10pm, select desired days of week(say, Monday, Tuesday and Wednesday) and select action "Set silent mode". That's it! Your phone will automatically switch to silent mode at 10pm on every Monday, Tuesday and Wednesday. Here's an example: - Switch ringer off at night and switch it back on in the morning. - Wake up to your favorite music by launching your internet radio app. - Make your screen brighter during day time and keep it darker in the evening to save battery. - Switch WiFi on when you get home and switch it off when you're off to work. - Automatically turn off mobile data when you go to bed to save battery and turn it back on when you wake up Phone Schedule is highly configurable, supports multiple tasks at one time, lets you specify days of week when you want specific tasks to run. If you want every task to trigger a notification in your phone's notification bar, you can easily enable notifications on the Settings page. Disabling notifications is just as easy ;) "Pause Tasks" function, use it when you have unexpected business meeting, so scheduled tasks won't execute during a timeout which you set. Phone Schedule runs in background, so once you setup your tasks, you won't need to reschedule them manually, everything is done automatically. List of supported actions: - Silent mode - Vibration mode - Normal mode - Switch WiFi On - Switch WiFi Off - Switch Bluetooth On - Switch Bluetooth Off - Airplane Mode On - Airplane Mode Off - Change Ringer volume - Change Media volume - Change Alarm volume - Change Notification volume - Change Ringtone - Silent Ringtone - Change Notification Tone - Silent Notification Tone - Brightness - Auto - Brightness - Full - Brightness - Cutsom - Dim Screen - Launch an app - Mobile Data On (May not work on some devices) - Mobile Data Off (May not work on some devices) - Reminder The list of actions is continuously growing, stay tuned for updates! About permissions: * Access network state, Change network state - To enable/disable mobile data * Full internet access - for crash reports, this greatly helps to debug the app and prevent crashes * Change your audio settings - to set silent/vibration/normal modes and change volumes * Automatically start an boot - to start working on your tasks automatically on boot after you reboot your phone * create Bluetooth connections, Bluetooth administration, change WiFi state - to switch WiFi and Bluetooth On and Off(No data transmission!) * Modify global system settings - To enable/disable Airplane mode * Prevent phone from sleeping - to execute your tasks when your phone is sleeping </code>

When I select "Flash ClockwordMod Recovery" from the ROM Manager menu a list of devices is presented ("Confirm Phone Model" dialog). There I can choose e.g. between "Samsung GalaxyS i9000" and "Samsung GalaxyS i9000 (MTD)". What is the difference between the MTD and the non MTD versions? When would I choose what?
|
MTD (Memory Technology Device) is a type of Partition Map (configuration of partitions of NAND). Partition Map allows those who are using it control over how their partitions are sized and how much space is allocated here and how much space is taken away from there. A file system resides on the Partition Map and governs the data being read,wrote,moved etc by the OS (Android). Changing a file system of a partition is very easy, but changing overall Partition Mapping isn't. Plus, partition mapping decides which file system to support. So, its choice is very important. MTD is Open Source. MTD supports YAFFS2 as a file system residing on it governing how data is transferred and the speed of which it is done. EXT2 through 4 aren't possible with MTD. Due to Open Source nature, it gives you full control over partitions. Choose MTD if you use CyanogenMod or MIUI type custom ROMs. A Bit of Knowledge: Samsung's stock ROM uses BML partition map. BML is proprietary in nature. It's Close Source.
