I have intermittent issues with multiple apps forcing closing. This has happened on both my current ROM (Miui) and every version of Cyanogenmod I've tried. Usually this problem crops up again a few months after a fresh ROM install or factory reset. I'll switch from 3G to Wifi, or vise versa, and then everything on my phone that uses background data will start force closing. The most usual suspects are Google Services Framework (com.google.process.gapps) and Facebook (com.facebook.katana), but almost any app seems to force close including ScoreCenter, Docs, and Smooth Calendar. In addition to the force closes, the other big symptom is that I can't turn off or on airplane mode, mobile network data (3G), wifi, or background data syncing - but usually not all at the same time. Sometimes I'll be able to turn on Wifi but not airplane mode, or other times I'll be able to turn 3G off but Wifi won't turn off. Sometimes I'll be able to turn a service off or on after a reboot, other times not. Sometimes when I reboot a service that I turned off before will be back on again, other times not. Incredibly, utterly frustrating. Neither rebooting, fixing permissions, nor wiping dalvik cache seem to help. I've only ever gotten my phone to work again by fiddling around with the radio settings and pulling the battery for hours before something magically starts working again. This most recent time I've even removed my Google account from the phone but that hasn't helped either. I know a factory reset would make this problem go away (for a little while, at least) but it always returns - I want to find the root cause and change whatever is making it happen in the first place (especially if it's something I'm doing!). I know that this issue involves the interaction between app syncing and the wifi/3G radios but I have no idea what or why. I've uploaded a logcat here - I hope you all can make heads or tails of it. I saw <code> E/ACRA ( 1296): java.io.IOException: No space left on device </code> and presumed it might be a partition storage space issue but all the partitions I could see (including those that require root) still have space. Thanks in advance, I'm super frustrated with this one.
|
After investigating further and looking at the partitions again, it turns out that I did have a totally full /data/data (as described stackexchange-url ("in a previous question")). For posterity, here's what I did: Because DiskUsage , the app I normally use to investigate partition usage, had locked up as well I fired up Terminal Emulator (luckily it was still working) and followed this advice I found in an XDA thread : You can check [the partition utilization] by running this command as root: <code> df /data/data </code> If you see % used = 100 then this is your problem. It was, in fact, 100% full. As soon as I moved some apps to my SD card my phone immediately started working again. I must've misread the free space of the partition when I first looked into it (doh!). The radio issues I was sure were involved ended up being a red herring.

I have a stackexchange-url ("rooted A500 with HC3.2") and I strongly believe that the stackexchange-url ("focus problem") is hardware. Since I'm under warranty I don't think I'll waste my time and send the tablet to repair. Two questions: How do I fully backup my device (let's say "snapshot") in order to easily restore all apps, wallpapers, settings, etc (possibly accounts too) when it returns? I can easily backup programs, but I don't know about their data. I also have a Bitcoin wallet there, so I need to back my private keys up in order to receive coins at the same address later. How do I un-root and downgrade the firmware to Acer's original stock 3.0? When I updated Recovery I did a backup, so I believe the final step is to restore that backup. By the way, does Acer consider rooting a warranty breach for hardware problems? I know many manufacturers don't care if you change their firmware when you send them a device with clear hardware problems, but they eventually restore everything to stock. Thanks.
|
I could have found the solution by myself. Not sure because I haven't tested it yet. For the backup/restore: Titanium Backup ( tutorial ) For the downgrade/unroot thing: first I could restore Acer's original recovery via Acer recovery installer, then I could downgrade to HC3.0.1 with this I'll give it a try It works perfectly!!!

As you know, Galaxy Nexus supports only MTP protocol for USB connection, which is not greatly supported under Linux. As a workaround, I have tried to upload my music to Galaxy Nexus through WiFi. I have installed "WebDAV server" (The Olive Tree) from Market and uploaded a couple of tracks to Music folder. But, Music app on the phone does not see any music, shows just "ways to add music..." message. Is there a way to force a rescan?
|
Specific solution for my problem is to install Rescan SD application from Market and launch it after uploading music through WebDAV.

For about the past month or so, whenever I pull my HTC Evo 3d off the charger (wall primarily, haven't tested against USB yet) the phone is unresponsive for anywhere between 15-60 seconds, and it's getting worse. If I pull the phone off with the display turned on, it will stay turned on in a frozen state; it does the same if I pull it off with the display off, just frozen with the display turned off. The battery is frequently incredibly warm but not quite hot. The unit is running stock Android (after a couple of updates; 2.3.4 Gingerbread, Sense 3.0). What could be causing this? To me it sounds like some kind of power regulation problem, perhaps from it switching from AC to battery power. How can I diagnose what is going on that is causing the overheat (is overheating a regularly reported defect of the Evo 3D)? I am becoming more worried about long-term damage not only from the freezing, but from just charging my phone. So, most importantly, what steps should I take to fix it?
|
I have minimized the impact of this problem by disabling the <code> [Stay Awake] </code> setting (Settings | Applications | Development). This setting had been enabled and once I had turned it back off the screen display became responsive sooner after unplugging. Apparently this setting on the HTC-Evo 3D is problematic.

I somehow cannot use the music app in android without linking it to my google account first. So - against my will - I linked it to my google account. I did this because I was hoping to remove that link later from within the app. As it turns out, this is not possible. I do not use google music and want to avoid granting access to private data when it's not necessary. Question Can I use the default music app in ICS without linking it to my google account?
|
I'd guess this isn't CM9 specific, but based on a quick test on my Kindle Fire you can just hit the <code> Back </code> button on the account select screen the first time you launch Music and it will simply skip it. Also, you can unlink your account by clearing the Music app's data in your settings ( <code> Settings->Applications->Music->Clear Data </code> ).

I need to encrypt my full file system on Android device. From this link, I understand that Android provides support to enable full file system encryption based on a password but that need to be enabled explicitly. However, this link doesn't give complete details about the implementation (particularly for new users). Has any one enabled this kind of encryption so far? Do people think that this is safe to do or it has some other drawbacks?
|
In Honeycomb the option is in <code> Settings -> Location and security </code> . In Ice Cream Sandwich it's at <code> Settings -> Personal -> Security -> Encryption </code> . If you're wondering about how Android does encryption, take a look at this: http://source.android.com/tech/encryption/android_crypto_implementation.html Naturally encrypting and decrypting requires some overhead, but I wouldn't expect it to be too bad. Undoing encryption does require a factory reset, so if you're doing it "just to try" you may want to do a backup first. If you're worried about security then I would definitely advise you to use it.

I have this working well for the Skype client on Ubuntu Linux, but I don't see any option to do this in the Android client. I would like to configure the Skype client for Android to automatically answer calls from contacts. Is this possible? Thanks!

Currently and sadly, there's no such option to allow the action of auto-answer an incoming Skype call. You can keep an eye out on this threads, maybe in a nearby feature such solution will arrive: Skype Support Network: Auto answer incoming call on Android OS XDA Developers forum thread: [RQ] Skype auto answer XDA Developers forum thread: [Q] Skype Auto Answer Additionally, 3rd party solutions aren't possible to this end, since Skype uses a proprietary protocol with no available API as explained on this stackexchange-url ("Stackoverflow answer").

Got a galaxy tab 7 SCHI800BKV verizon wireless tab. It has no rim/sim port. Question is if I root the device will it be possible to set my country's CDMA operator in the device? Thanks for your help.
|
The device may have to be unlocked first. Rooting will not Unlock the device. You will also need information from the network you want to run the device on. Like if the device is supported on their network, if they are able to active the device (they will be able to tell you if they support it if you give them the ESN/MEID) and what their mobile carrier code is (SID/NID/MCC). I did find this info that may help once it is unlocked: From here, I will walk you through programming the tablet for ota activation with that carrier. If its the verizon galaxy tab, to get to the programming menu go to the notepad and type **772 to get to the manual programming. the spc code will always be 000000 from here touch down 3 times clear out the directory number with 10 0's then hit down then clear out the msin with 10 0's from here touch down here you will change the system id to what is necessary for that carrier. then you will hit left or right and then enter then hit down 4 times and you should see mcc, put the mcc number here then hit down 4 times, and the home sid should match the one you input, then you will change the NID for that carrier as well then you will hit down 64 times, and make sure cdma homesys reg is yes then hit down 6 times to where it says slot cycle index, change this to 1 by hitting touch here and clear it and hit 1 then exit service

Is there any way to trigger the behavior that usually occurs when a mouse is hovered over an element (for example, hovering over your username at the top of a Stack Overflow site) using the Chrome Beta browser?
|
One way to trigger the hover on links is to long-press the link, wait for the menu to appear, and the press the back button to cancel the menu. This also works in some other browsers. Note that this doesn't work on all links. Just tried on the example you mentioned, doesn't work, probably because there's a slight delay between the onMouseOver event and showing the menu. But on other pages, where it's a simple onMouseOver trigger this method works.

I'm running version 4.1.511 of the Google Music app. When it downloads songs for offline use they are stored in /sdcard/Android/data/com.google.android.music/cache/music This folder has a .nomedia file in it which prevents the media scanner from scanning the files. This means other music apps that I run don't see the songs? Is there any problem with removing the .nomedia file from this directory so that the files can be scanned and picked up by other media players?
|
The .nomedia file is for the reason you stated. You can safely remove the file and other apps will be able to pick up the medias in that folder. In any case, if there is any problem you can easily create that file again. It can be a empty file with the name .nomedia. You can use programs like ES File explorer to explore to that directory and create the file. EDIT: As per the comments below which contains very useful information: Your Music apps may recreate the .nomedia file when you launch it. Other players will only be able to play the music if only the musics are DRM free.

I have a Android tablet for which I want to do a factory reset, and then install some pre-defined applications. This has to be carried out by someone who has no computer experience and no Android experience at all . All I get this person to do is connect the device to a computer by cable, and interact with a very simple interface with a couple of buttons. All this has to be performed on a well known device and only for that model. Is it possible to connect a device to a computer and with a couple clicks do all that? If so, are there any suitable applications which do that already? Would it be necessary to create software for that? Rooting is no problem.
|
Possible solutions, in descending order of idealism and difficulty: Create a custom ROM, with the apps you want on it, which you can flash onto these devices. stackexchange-url ("This question") is a good starting place for that. Write your own app, which automatically installs the other apps. The first answer to stackexchange-url ("this thread") provides the code to install apps programmatically. The easiest solution, if it suits your needs, would to be to use one of many "installer" apps. If you can drop the apps on the tablets after installing your stock ROM (ideally on an SD card), you could then install an "installer" app. Then either run it yourself, or instruct your users to run it and install the listed apps. In any of these solutions, you will have to write the desktop computer application which has the few-button interface for users, which does the flashing and installing. Whether you do a custom ROM or a stock one, you will have to automate its install. This thread has some help on automating ROM installation.

What does the <code> modify/delete USB storage contents </code> permission really mean? Does it grant access for the application to read, modify and write all the data on my USB storage? Maybe it is this only limited to a subset of that data (e.g. only data written by the application itself)? Or does it mean something else entirely?
|
If you are familiar with the concepts of read and write permissions on various PC platforms, that is pretty much the same as what is going on here. You are giving the application write access to your "external storage" Which could be an SD card, or some storage space that comes with your device. That permission indicates that the application is able to create, modify, or delete any files that reside on the SD card (or the non-removable storage space that the the OS treats most like an SD card). So it could download a file from online and manually save it to your SD card. It could generate its own image, text, audio etc.. file and save it to your SD card. It could delete any file on your SD card. It could find a file that already exists on your SD (even one with nothing to do with the app) and make changes to it.

I want to remote control Google Doc Presentations. Is there an app for this? Bonus point if it can connect via Bluetooth to my Linux-based PC.
|
You could simply use a bluetooth/wifi mouse app like PRemoteDroid . There are a bunch of others , and generally speaking they just allow your device to be used as a mouse/keyboard input. If you can pair with your PC it should work, although I've never tried it myself (I do use PRemoteDroid to pair with and remotely control my Xoom, though; works great). Another option would be some kind of VNC or remote desktop client , but that's not as lightweight and some of them don't support Linux (Splashtop, for example, doesn't have a Linux server, IIRC).

I have some apps installed on my device and I want to perform a factory reset. Is there a simpler way to re-install my applications after the reset (with the least possible number of user interventions), without having to search them all in the Market and re-install them again one by one? Rooting is not a problem. Thank you in advance.

If you have a 4.x device, the automatic backup/restore found under <code> Settings -> Backup & reset -> Back up my data </code> and <code> Automatic restore </code> options work fine. It uses Google's own servers to save a list of apps installed on your phone. After a factory reset once you sign in with the same Google account, it gives you an option to restore those apps. Keep in mind that if the goal of factory reset is to change the default Google account, you'll need to first add that account to the phone, and change the <code> Backup account </code> to the secondary one you've just added. On older Android versions the automatic backup/restore was not very reliable, but there are some 3rd-party apps in the Market that can help depending on what exactly your goal is. If you want to simply re-install apps, then AppBrain along with Fast Web Installer are great. AppBrain allows you to save the list of your installed apps to their online site, and after a factory reset you would only need to re-install these two apps, sign in, pick the list you created earlier, and it allows you to kick off a process that automatically installs the "missing" apps directly from Market. If you also need to restore the settings and data associated with those apps, Titanium backup (rooting required) is a better choice. This app backs up all installed apps and their settings/data to your SD Card. After a factory reset you install Titanium from Market, and then do a restore. It can also backup/restore system apps and settings, which can help after a factory reset, but it's generally not recommended to do so, especially if you are planning to install a custom ROM.

Android tracks events that affect battery usage and stores this information in batterystats.bin file. Some examples: length of time screen was on with a specific brithness setting which application (or non Android app process) and how long held a wake lock (prevents device from sleeping) CPU usage per process (Android app or other process) phone signal strength GPS usage etc. Android computes how much power each Application or component (e.g. screen) uses based on configuration information included on the device by the manufacturer. Not everything is measured so the statistics can be sometimes misleading, but it gets better with every Android Platform release. Battery statistics can be dumped from the device using: <code> adb shell dumpsys batteryinfo </code> Here is interesting fragment of a post by Diane Hackborn with more details about wake locks power consumption: There are two ways power from wake locks is computed. On some chipsets, simply holding a wake lock needs to prevent the CPU from going to a full deep sleep. In the reported battery usage, this extra power use will be distributed across all apps holding wake locks. Even if the wake lock itself doesn't cause power use, holding a wake lock in one app can allow other applications to run and CPU when they wouldn't otherwise. (For example, some app may have a { sleep(1); do something; } loop that wouldn't run if no wake locks are held.) To address this, half of the CPU usage of applications is distributed to be blamed on the ones holding wake locks.

I'd like to have all the text displayed in English (US), but use the Polish (Poland) formatting for numbers, dates etc. On a desktop Linux system, I'd set LANG to pl_PL and LC_MESSAGES to en_US.

Note: I am not asking about the keyboard, I know can set it to use a language different from the language+locale setting without problems.
|
I've set my phone to English (United States), but then I also customized Date & Time to use Italian format (DD/MM/YYYY). Numbers don't seem to be customizable, plus some apps ignore Date & Time settings and use the ones from the main language, or allow to specify a format.

I'm having a problem with music playback stutter on my Galaxy Nexus, and after searching about it for a while it seems the problem was fixed on update 4.0.4. Unfortunately, my phone is still on 4.0.2 and no OTA Update is currently available. From past experiences with my Milestone, updating or using a ROM that was not originally from my country (Brazil) resulted in various problems, including no 3G connection and very poor GPS signal. Is it possible to actually update the Galaxy Nexus manually from 4.0.2 to 4.0.4? If yes, is there a way to know which "version" of the system would be compatible with mine? Here's the "About Phone" tab on settings: http://i.stack.imgur.com/0VZhk.png
|
AFAIK, the 4.0.4 is currently only available for the CDMA/LTE, but someone over at Modaco has a modified version of the 4.0.4 working for GSM. It looks like everything is working on the GSM version with this modified release. I have also read that 4.0.5 will be released next month, so you may want to just wait.

I followed the instructions on the source.android.com website to download, build, and install Android OS v4.0.3 on a Nexus S. Everything seemed fine, I could take pictures, access WiFi to surf the web, etc. The problem is that there is no Market app and I have been unable to install anything via the Market over the web. The apps I had on the phone prior to loading ICS all show as "installed" on the website but they will not sync with the device. Any time I try to install a new app, everything seems to go ok and then it says the download will begin shortly but it never does. I have tried many different things described on posts such as resetting to factory defaults, clearing cache, etc but nothing works. Does anyone know how I can load the Market app or somehow download apps from the Market to manually install?
|
If you built the image yourself then Google's proprietary apps would not have been included as they are not open source. The easiest way to get them is probably to just use the CyanogenMod9 gapps package, which can be downloaded here (top of the table). If you have a custom recovery image then you can simply install the .zip file from your recovery, otherwise you'll have to manually install each of the files in the .zip (they have a folder structure that mimics your device). The reason why the web Market isn't working is because it tries to use C2DM to push the app to the device, but this requires the Market app to be installed on the device. You cannot download the .apk from the Market manually.

Android got a brand new camera app with ICS. The old camera app from previous android versions didn't play a sound when the phone is in silent mode, the new one does. Obviously this can be somewhat anoying in some situations. Can this sound be muted? Note: I'm asking for an answer that doesn't require a rooted device . I'm aware that I can rename/delete the sound files from the system (as documented in stackexchange-url ("this question")), but I'd rather not root a device just for this.
|
Alright, I went through the sourcecode and the answer is surprisingly obvious: Yes, this can often be muted by simply using the volume keys while using the app or adjusting the volume of the media audio channel in the preferences. The media volume is used, regardless if the device is in normal, silent or vibrate mode. But it depends on where you bought your device if this works (I guess) , some devices enforce audio over a channel that can't be muted. More (technical) details: The camera app checks the device configuration (system property <code> ro.camera.sound.forced </code> ) whether it should play the camera sounds over a system-enforced audio channel that can't be muted. If this setting is off, it uses the media and music channel instead. In case that it uses the music channel, it ignores when the device is in silent mode though. This might be a bug/small oversight by the authors. This is why you have to adjust the channel volume instead. I guess the property mentioned above is set depending on where you buy your device, since the sound is required by law in some places/countries as explained by eldarerathis in the comments.

If my Android device is stolen, will the person who ends up with it be able to get my data by plugging it into a PC and using some trick? Is there anything I can do to prevent this or make it harder?
|
If you used full-disk encryption, then your data will be accessible until the device unmounted the encrypted disk (e.g. by rebooting) and discarded the decryption key. If you store your sensitive data in encrypted container, then your data will be accessible until the application closes the container and discarded the decryption key. If you don't use any encryption, then your data is naked in the wild. Many thiefs are simply interested to sell the phone to make a quick buck and so will simply reformat the phone; but if the thief has a specific intent to steal your data (e.g. corporate espionage, identity thief, etc), then you can assume that they can read all your unencrypted data. If your phone uses SD card (instead of internal memory), then getting to your data in the SD card is trivial. Getting data in internal memory took a little bit more effort, but is still relatively easy. A turned off device with full-disk-encryption is -- for all practical purpose -- a useless brick for your adversary.

I like to leave GPS enabled so that it's ready to go when I open Maps or certain other location based apps. However, one app that I don't want to access GPS is Facebook. There is, as far as I can tell, no option within the Facebook app to prevent it from trying to access GPS whenever it starts. Is there another app or setting I can use which will allow me to leave my GPS enabled, but block specific apps, like Facebook, from accessing it? Note: I took a look at stackexchange-url ("this question"), which suggested using Tasker to essentially whitelist certain apps. I have Tasker installed, but I can't get it to do what I want, which is essentially blacklist specific apps. Note 2: My phone is not rooted, and I hope to find a solution that does not require rooting. Note 3: I have Android 2.3.6

The stock contacts app of Android 2.3. (and older versions) had a filter that displays only contacts with a phone number, accessible under <code> Menu -> Display Options -> Only contacts with phones </code> . This seems to be gone in android 4. The other display options moved to <code> Menu -> Settings </code> , but this one is missing. It's also not under <code> Menu -> Contacts to display </code> . Does anybody know if this option still exists and where it is if thats the case?
|
In Ice Cream Sandwich, the old Contacts app was now replaced with the People app. This new app is meant to keep you connected with all of your contacts, not just people you call, and it does so in different ways then the old contacts app, by hooking in to social networks and things like that. The option to only show contacts with a phone number is not an option in the new People app. But I agree that it should be there, especially when you are searching for a contact when you want to make a phone call.

The required part of a kernel .zip file looks like this: <code> META-INF com google android update-binary updater-script </code> You'll also want to have the kernel <code> zImage </code> file somewhere else, easiest if you just have it in the root of the archive. <code> updater-script </code> contains the following at minimum (assumes <code> zImage </code> in the root): <code> assert(package_extract_file("zImage", "/tmp/zImage"); write_raw_image("/tmp/zImage", "/dev/block/mmcblk0p8"); delete("/tmp/zImage") ); </code> You can also do things like show a progress bar, print messages, wipe <code> /cache </code> , and so on. You'll want to grab <code> update-binary </code> from another kernel package for the SGS2. One at random is attached to this XDA post . I tested this method on my SGS Vibrant without issue, using a kernel from an Odin package and an <code> update-binary </code> from another Vibrant kernel .zip. Note that this is perfectly safe as long as you're writing to the correct partition -- for the Vibrant it was <code> bml17 </code> , for the SGS2 it appears to be <code> mmcblk0p5 </code> (based on the kernel from XDA I linked above) or <code> mmcblk0p8 </code> if you're flashing an entire boot image (see comments below). You'll want to verify it for sure. Worst case your kernel doesn't work and you flash a known good one.

I am using the Sony Xperia Arc phone. I came to know that,The Official Mobile Update OHLA(open handset alliances) will be delaying the release of Android OS(ICS 4.0). I have a little confusion about updating Android OS.I have seen some mobile OS update forums and they mentioned that we can update our Android phone easily to higher version i.e. Android OS(ICS 4.0) by rooting the device.But it seems the mobile warranty will be broken,the data will be lost and even we can find the bugs as well while updating through custom OS though we can update easily. So I want clear solution for this confusion so could any one help me for this problem. What would be my further steps for updating it to 4.0?
|
According to Sony's official statement , Ice Cream Sandwich (a.k.a. "ICS", a.k.a. Android 4.0) is coming to Xperia Arc at end of April or beginning of March of 2012. If you are worried about the cons of rooting (i.e. voiding warranty, possibly breaking the handset, etc.) I would suggest that you wait for the official update from Sony and/or your carrier.

Lately I've noticed some weird behavior with my Galaxy Nexus. I am rooted, but running stock ICS. Here is what it's doing wrong: Phone sometimes will not charge, I must turn it off for it to start charging Taking phone off the charger doesn't remove the lightning bolt [charging icon] from the notification bar. Phone begins alerting constantly at 14% battery. Battery life seems shorter Is this likely to be an app doing this? I don't want to wipe my phone if possible, so is there a way to track down the cause?

According to the official bug report here, starting at about post 26, it seems the sentiment is that this is a hardware issue. I have contacted Verizon and they are shipping me a replacement. I will update the question again if this does not permanently resolve the issue. http://code.google.com/p/android/issues/detail?id=23789&q=label%3APriority-Medium&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars

What I'm looking for: Is there a way to make the device claim to be a keyboard/HID when plugged into a USB port and "type in" the contents of the clipboard? More accurately; What would it take to make it happen? Motivating use case: I have a password keeper program on my phone but it's annoying to have to read the password off the device and try to type it into another computer. Background: I have an Android device that was built before MTP was supported for transferring file but, with recent upgrades, now supports it. Based on this, the USB class that it claims to be can't be hardware defined and must be defined in software. IIRC, this project has Android devices (with what I think is a stock kernel) talking as some USB class that was definitively not built in. This indicate to me that you might be able to control what USB classes it support without kernel work but I don't know for sure. As for the Host side (i.e. the PC), I've never seen a PC, Mac or Linux box need special drives for keyboards, even for some rather esoteric devices that claim to be keyboards (bar-code scanners, credit card and smart card readers, etc.) so the generic drivers should be good enough for what I'm wanting. All that argues that what I'm looking for can be done from a hardware point of view , but says very little about what software support exists and nothing about if there is an app for it.
|
Yes. This is definitely possible, requiring no modifications or drivers on the PC. As the OP mentions, the USB identification on the phone end is ultimately done in software (in this file https://github.com/android/kernel_msm/blob/android-msm-2.6.35/drivers/usb/gadget/composite.c), and it could be modified to identify itself as a standard USB keyboard. This change would require a couple of things. A modified kernel with a patched USB driver An Android app that could talk to some interface exposed by the modified USB driver. There was a paper published a couple of years ago (titled Exploiting smart-phone USB connectivity for fun and profit ) that described using a phone to brute-force desktop login screens. The method they used involved making the phone appear as a USB keyboard.

Vibrant support was dropped from CyanogenMod after 7.1 (Gingerbread) due to issues with failed 911 calls . I flashed 7.1 a bit before this was made known, and have since reverted to my stock-based ROM. This is obviously a bit concerning and I have a few remaining questions: Did flashing CM damage anything? (I.e., will emergency calls work now that I'm on a different ROM?) Can this happen with stock-based ROMs? Was it all emergency calls, or just 911? Is it related to Gingerbread? Has it been fixed in CM? I've seen a few things both ways.
|
The official announcement on the CM forums states: The issue was in the RIL code, which is just typical code and libraries packaged in the ROM (e.g. <code> /system/lib/libril.so </code> , for example). The CM team recommended installing a Samsung ROM noting that any Samsung ROM is fine and any AOSP ROM would have issues. There's no permanent damage since the RIL code was replaced when you reflashed. They specifically cited the issue was related to closed-source RIL code, so this wouldn't happen with a stock ROM unless Samsung severely borked their RIL code. Only 911 was listed as a problem, but I don't know (and neither have the CM team ever stated) if other emergency numbers were affected. Official support for the Vibrant didn't occur until 7.1, which was Gingerbread. It's really hard to say if older versions were affected, but I would assume yes (if they exist somewhere still). The announcement states that the issue was fixed and the Vibrant is officially supported at this point.

Being that ICS is the merging of the phone and tablet versions of Android, what is different in ICS when it is used on a phone from when it is used on a tablet? ** Clarification:** This is referring to vanilla ICS
|
Assuming just vanilla ICS, with no custom UI from a manufacturer/carrier or anything: A phone has a status bar at the top and soft buttons (or hardware buttons) at the bottom. A tablet will only have the bottom bar, with soft buttons on the left and clock/notifications on the right. The notification pane pulls down from the top status bar like in previous versions on a phone, but it pops up from the bottom-right corner on a tablet. The default launchers and home screen layout are visibly different. The app drawer on a phone is in the center bottom, on a tablet it's top right, and phones have a sort of "dock" at the bottom that is visible on all home screens (tablets do not). Also, the Google search bar collapses on a tablet but is persistent across the top on a phone. The home screen transition animation is also different. Apps that use the Action Bar will display a bit differently. On a phone the bar will almost always be split between the top and bottom of the screen, with some options on each portion of the bar (possibly unless they use very few icons/actions). On a tablet it just uses the top of the screen because there's plenty of room. Google Music is a good example of this.

I have a Samsung Galaxy S (AT&T Captivate) that is rooted. I have various ways to tweak the amount of free RAM the OS leaves on the phone. The default is 48 MB, but I was wondering if I could actually go lower without impacting phone performance. Are there guidelines posted anywhere, or that can be deduced based on knowledge of the Android platform? Or should I trust that the default settings are appropriate? I understand that when it comes to free RAM, more isn't necessarily better, but I understand that there is still a threshold that I don't want to dip below. I'm running a 2.3.6 Gingerbread based ROM. For what it's worth, I'm running the Zeam launcher.
|
In the "linux world", what android is at its core, free RAM is wasted RAM. The system will attempt to use up as much RAM as needed. If more is needed, and there are applications that are no longer requiring the RAM it has allocated, the system will free up the RAM from that application an allocate it to the new application that needs it. Having less RAM available will not necessarily affect the performance. What will affect it is if it frequently needs to free up RAM on the system for other applications. meaning if there a lot of running applications that are Active, and require the RAM, then you can see performance issues. This is because the the system needs to save the state of the application, free up the RAM and then allocate the freed RAM to a new application. As for what a "low point" might be, I can't say. I have NEVER watched my available RAM, and never really experienced any performance issues because of RAM. for the record, I have the same device (but the T-Mobile version).

I am new to this flashing business for the Android tablets. I did some of those flashing on a PanDigital tablet previously, but it's been a while. My tablet is the standard 32G WiFi tablet, and it's been rooted. How can I get the cyanogenmod ROM installed, and how does this fastboot thing work ? I also have the recovery.img file. BTW: How can I backup the existing ROM, so I can restore if something goes wrong ? Thanks :-)
|
If it is a supported device, then this should basically be the process as it is the same for every supported device I have experienced. Put the cyanogenmod update zip file on the device sdcard (or internal storage) Also put the google apps update package that corresponds to the CM version on the sdcard Boot the device in to recovery mode You can create a backup in the Recovery image (probably clockworkMod recovery) clear the cache and wipe the data install zip from sdcard (selecting the cyanogenmod zip) install zip from sdcard (selecting the google apps zip) reboot the device. If you have ROM Manager, a lot of this process may even be easier. With ROM Manager, which can also install ClockWorkMod Recovery if it is supported on the device, you can download CyanogenMod, the google apps package, clear the cache and user data, and perform the backup. It will then reboot the device and perform all those steps. Now, as I said, I am not 100% sure that CM is supported on this device, so there may be other steps required to get an unofficial version working on the device. With that said, Samsung devices are usually pretty easy to get back to the Stock version if something goes wrong (soft brick). It is pretty hard to brick these devices, I have had a couple scares, but I have always been able to revert back to original stock ROM by using ODIN.

If you install a completely original ROM for the device, it will be unrooted. flashing the correct Stock ROM for your device will revert it back to its original factory state.

I changed the system font (by Font Changer) to Ubuntu font (0.8). This font has Latin-Extended support and can display Vietnamese just fine (I tested this on http://font.ubuntu.com/ ). However, after I changed to this font, Vietnamese chars are replaced by boxes. Can anyone explain this for me? Any idea on how to fix this?
|
I'm not sure about Vietnamese, but for example in Finnish, there are some extended characters that are problematic. This is because some pages are encoded as ISO-8859-15 and some are UTF-8. If autodetection in the browser fails, they will be displayed as boxes or garbage. The same thing happens if the font only supports one encoding and the page uses the other. I'd recommend to check the encoding of the font and the encoding of the pages you tried, and change the font if necessary.

I'm running ICS on a Galaxy Nexus and my data plan is grandfathered in from the days of unlimited data with my carrier- so I don't need any warning or notification for the amount of data I'm using. However, ICS on this phone has an annoying warning and notification when I hit either 2 or 4 gb before the month is over. The notification persists in the background and will not close. How do I disable this?
|
In <code> Settings -> Wireless & Networks -> Data Usage </code> you should be able to uncheck the "set mobile data limit". The limit will stop data usage when you reach the limit. (You probably have this unchecked already). On this screen is where you can move the "warning" levels up so you will not reach them and you will not receive the notification. One thing to note: If you have mobile data disabled, the checkbox to set the limits will not be visible. Re-enable it temporarily and you can dispatch the annoying notifications for good.

I've tried three different folder widgets for Android 2.3, but I noticed none of them supports adding applications via drag & drop, like the native folders do. Is that even possible to do? I guess it isn't, or those application would be pretty stupid not to support it, but you never know.
|
The only interactions presently supported by app widgets on the home screen are simple click events. So the answer to your question is no, drag & drop isn't available with widgets. The reason the native folders can do this is because they are just part of the launcher activity so can be programmed to do more complex things than the widgets can

Most of the information is available in <code> Settings -> About Phone -> Status </code> but you can also use an app from the market called Battery Info (i am sure there are others as well) and it will show you all the information on the battery. This app also has a widget that can display some information too. At the time of me writing this it is not possible in the android SDK to get the stackexchange-url ("raw mAH") value so you wont find any apps that can display the exact mAH, only how charged the battery is in percent, and what is drained.

The recent apps list in Ice Cream Sandwich added the ability to swipe apps out of the list, thereby dismissing them permanently (and as far as I know this is a vanilla function, not a CM/custom ROM one). The documentation and platform highlights don't appear to cover the under-the-hood workings of this functionality, but I'm curious to know what the system is actually doing. Further adding to my curiosity, I decided to do a quick test: I started up Music on a CM9 install, then backed out of it. I then checked the recent apps list and saw it was indeed there (and in the proper state, based on the thumbnail). I then went into <code> Settings->Applications </code> and force stopped the Music app, but it was still listed in the recent list, leading me to believe it's not connected to processes lingering in the background. Realizing now that Music may have been a poor choice, I also tested with the USA Today app. This exhibited basically the same behavior, and it seemed like it was forced to "relaunch" after the force stop (which makes sense) though the thumbnail in the recent apps list didn't reflect this (cached, I'm guessing?). So, what actually happens at the OS level when you swipe an app out of the recent list? Does it simply clear the app's data out of RAM and garbage collect it, destroying its saved state?
|
Swiping apps out of the recent apps list is vanilla, and yes, not well documented. This has been the topic of a decent amount of discussion on various Android forums... the consensus seems to be best described here in some comments : that the behavior is similar to but not exactly the same as closing an app -- in general (for apps that don't define explicit back button handling) it's the same thing as hitting back enough times from within an application that you exit out of it. The link has some more details on the specifics, but overall you can think of it as quitting the application. Specific to the Music app, I believe it starts a service, so while the task itself (the Music app/UI) may be closed, the service continues to run in the background so that your music doesn't suddenly stop just because the task got cleared out for memory management reasons. That may have affected what you saw.

I know that one of the new features is WiFi-direct for ICS (noted at the very bottom of the page in the link). Is there a way to leverage this new feature to transmit files from one ICS device to another? This would be useful because the WiFi speeds would be greater than bluetooth, and you wouldn't need to be connected to a WiFi network or create a hotspot. The Samsung Galaxy S II apparently has this feature built in pre-ICS (go Samsung!). Is this same method available in ICS? Or is there an app for it? EDIT: Because the galaxy nexus is made by Samsung, and is the only device out with ICS right now, I'm not sure if this "WiFi Direct" sharing (per the link and Ryan's answer below) is built in to ICS vanilla (Samsung did have WiFi Direct sharing pre-ICS, after all). As such, I've added a vanilla tag, so I'm asking, is in the vanilla source code to allow a way for users to share files using WiFi Direct? If not, is there an app for it in the market? I want to know how to do this on all ICS phones, not necessarily just the galaxy nexus.
|
Android 4.0 introduces WiFi Direct in to the core of android. it basically creates an adhoc connection between one device and another using WiFi by creating what I guess could be considered an Access Point. You do not need a wifi access point to use WiFi Direct, and actually, if you are connected to wifi when turning on WiFi direct, it will disconnect you. You cannot be connected to both an Access Point and enable wifi direct. The host device acts as an access point for other devices to connect to, then through other pieces of software, files and other data can be shared or streamed to the client device(s). To use Wifi Direct, in <code> settings -> wireless & networks </code> you have to enable it. Then you should have an option to "share" via wifi. This works a lot like bluetooth sharing, where the other device has to be "ready to accept" your files. You will only be able to do wifi direct with devices that have explicit support for wifi direct. Android 4.0 is the the first version of the OS to have built in support for wifi direct. The Samsung Galaxy S II does have support for wifi direct as well. This was an added feature Samsung put in to their TouchWiz version of Android. While the settings for it are a little different then in Android 4.0, they basically work the same. There are other devices, like some TVs by Sony, that also have wifi direct support. Wifi Direct is not hardware specific, its part of the OS. If the device supports wifi then it supports this. It is part of the CORE OS in Android 4.0. Any device that has Wifi and is running ICS, this will work with. Some Samsung devices (I think only the Galaxy S 2) have support for wifi direct even though they are not running ICS. This is because Samsung added the support for it in to their version of Android. While the Galaxy Nexus is manufactured by Samsung, it does not run the Samsung modified version of Android. It runs a completely "Google Experience" version of Android. The WiFi direct that exists on the Samsung Galaxy S II is different then the one built in to Android 4.0. Here is the android SDK docs that talks about support. Wi-Fi Direct allows Android 4.0 (API level 14) or later devices with the appropriate hardware to connect directly to each other via Wi-Fi without an intermediate access point. Using these APIs, you can discover and connect to other devices when each device supports Wi-Fi Direct, then communicate over a speedy connection across distances much longer than a Bluetooth connection. This is useful for applications that share data among users, such as a multiplayer game or a photo sharing application. Here is a screen shot (taken from this video) showing wifi direct setting available on a Nook Color running CM9. The video is at the location where it shows wifi direct working. Here are 2 screenshots from my viewsonic g-tablet that is running ICS (this is not a CM9 Kang, it is vanilla AOSP android). The first shows the setting, the second shows that i turned it on. To show that WiFi Direct is actually part of the core of android and not just CM9, here is the source code for the WiFi direct settings. This is the github mirror of the AOSP. You can compare it to CM9 source too.

I use the amazon downloader to buy mp3s with my android device. My problem now is that I cannot change the download folder but want the files to be moved to my sdcard. I already found a cron tool to run scripts from time to time. All I need now is a shell script to move all folders (including subfolders and files) from internalmemory\amazonmp3 to sdcard\Music to be honest my knowledge is just good enough to do a "mv" but not good enough to go through all subfolders. I also am not sure about the directory structure of android devices. (pathes to sdcard and so on)
|
If you use <code> mv </code> on a directory containing files and subdirectories, it will move all of them. But in this case you may not want to move the <code> amazonmp3 </code> directory itself, so the command would be <code> mv internalmemory/amazonmp3/* /sdcard/music/ </code> , assuming the internalmemory directory is correct. The actual names for the internal memory and sd-card depend on the device, for example on my old Galaxy S they were <code> /sdcard </code> and <code> /sdcard/external_sd/ </code> .

Android Market has just updated an app in my device. I liked the update, but its fully different from last version which was also my favorite. So, I want to keep last version too. I have last version's apk thanks to Titanium Backup. But, I can't install it without replacing current one (Android architecture sucks). Is there any way to do this? Hacks etc.. Note: I want to keep current version which must be connected with Market to receive future updates.
|
It can be done, but not simple for the reasons stackexchange-url ("eldarerathis") mentioned. You need apktool . Refer to this guide on how to use it. And this on signing the apk after you're done. You need to modify the AndroidManifest.xml file. Find the line that looks like this: <code> manifest package="com.example.app" </code> and change it to something like: <code> "com.example.app.foo" </code> After you're finished, recompile then resign. To restore your data, try the following via adb: <code> adb rm /data/data/com.example.app.foo adb push /data/data/com.example.app /data/data/com.example.app.foo </code> Where <code> com.example.app </code> is the package name of the original and <code> com.example.app.foo </code> is the modified. There's always a slight chance that the app will break, or depending on the way the app is structured you may receive a dialog every time you change the screen prompting you to choose which app you want to launch, but it's definitely worth a try if you want it badly enough. Of course, the two apps will not share the same settings and data.

Some time ago I installed a custom firmware ( YAR28 ) on my Archos 7HT. This worked fine for a while, until some day when I switched it on it showed the initial startup screen, and after that all my installed apps were gone. So I re-installed the stock firmware from Archos. But then I found out I could no longer access the sd-card. It was not mounted when I inserted it. But when I connected the device to my PC using USB it did show up as drive F: and G:. I could access F:, which was obviously my sd-card, but G: (which should be the internal flash) could not be accessed, and Windows even asked if this should be formatted. When I open the Files on my tablet, and select 'SD Card' it gives the 'SD card is unmounted' error. And when I select 'Internal Memory' it is completely empty. So it looks like the file system is still working, but the internal flash part somehow is no longer accessible. I have a feeling that some low level setting has changed and that I could somehow solve it if I could get access to the underlying Linux system, but I do not have a clue how to proceed.
|
Indeed the internal filesystem somehow got damaged. To fix this you need access to the filesystem itself, which can be done using ADB. (Android Debugging Bridge) Instructions for connecting to the Archos Tablets using ADB can be found here: http://www.archos.com/support/support_tech/updates_adb.html?country=er&lang=en Although the description is complete this still sometimes can be hard. You might have to restart your computer a few times, but eventually it is possible. Open a command window in the directory containing the ADB.exe program (it is in the 'platform-tools' directory under the androis-sdk-windows folder) Type: ADB SHELL If the connection is OK, it will start a server and after e few seconds show the ' $ ' prompt. this means you are connected to the tablet and have direct access to the linux shell. If you type ' ls ' you will see a list of folders that contain the operating system and all supporting files that make your tablet work. Now navigate to the folder containing the Flash file system by typing: cd ./dev/block/vold If you now type ' ls ' again you should see three or four folders that have numbered names. One of them is '31:8'. This is the folder that points to the internal flash. Now we can fix our problem by recreating the MS-DOS (FAT32) file system on this partition. Type the following: mkdosfs -F 32 /dev/block/vold/31:8/ This will fix the FAT32 filesystem. Now leave the shell by typing ' exit ', disconnect the USB and restart your tablet.

My Eee Pad TF101 auto-updated to ICS today. After the update, all fonts in Firefox changed to some dreadful-looking Times Roman-like font, in which the accented characters don't show right. Stock browser and Opera look fine and use the newfangled ICS sans serif font. Deleting data and reinstalling Firefox didn't help. Maybe it expects the old 3.2 font? Is there a way I can install the old fonts in 4.0?
|
Got same problem. Here's a fix. Go to the advanced settings by typing "about:config" in the url string, filter settings by "font" substring and change the values of font names corresponding to your codepage from "sans..." (NOT mono) to "Roboto". Restart firefox

How can I configure my 2.3.5 phone so that I don't get a notification for automatic upload of images and videos in google+?
|
If you're talking about when your phone uploads to Google+ automatically using the built-in Instant Upload, then you can just switch that off in the Google+ notifications. In fact I think that you must have switched that on at some point because I'm sure it was off by default for me. Open the Google+ app, press Menu , select Settings , press Notification Settings , and then scroll down to the Photos category and take the tick out of "Photos added from Instant Upload". You'll still get the red notification box at the top inside the Google+ app, but won't get notified in the standard Android notifications bar any more. The other notification settings are there too, if you want to tune any of the others.

I have a Chinese tablet, so I cannot install apps from Android Market (at least directly). How can I see flv, swf and other kind of flash data using Dolphin web browser?
|
You can try side-loading a Flash Player apk file. There are a whole lot of them floating around on XDA, such as this thread which has a download for Flash 11. Whether or not it works will also depend on other factors, such as the version of Android on the device and the processor it has (Flash requires an ARMv7 processor and Android 2.2 or later).

I'm trying to configure my phone to sync with my work email account. I'm accessing it through OWA (Outlook Web Access). With the default settings, when the phone attempts to retrieve incoming mail, I get an error stating that there is an 'Invalid Server Certificate'. This persists even if I disable the Verify Certificate setting. Why is that? How do I avoid the 'Invalid Server Certificate' error? I do not receive the error if I set 'Use secure password' to Never. But, that doesn't seem too safe. Would that mean my password is sent in plain text? I'm running Android 2.3.3 on a Droid X.
|
This seems like an issue that has been reported to the android development team. I am not sure if it is specific to the droid x, but even the work item relates to the droid x. If that is the case, I don't know if that is technically an android issue, but a MotoBLUR issue, as the Droid X runs the MotoBLUR version of android. Also, Yes, that is what "Never use secure password" means.

I am going to connect a USB device to Android mobile phone, using Android ICS 4.0 USB OTG. Can I connect this device to smartphone through USB hub and connect the phone through USB hub to PC in order to deploy apps at the same time (using a male-male USB cable)? Will it be safe solution for both phone and my device?
|
I think you're saying you want the PC to be the host for the USB hub (so that it can connect to your phone) but for the phone to also be the host for the USB hub (so that it can connect to this other device). No, that won't work. USB connections are based on a tree structure. Given this: <code> PC----Hub----OtherDevice | | Phone </code> <code> Phone </code> can't be the parent of <code> OtherDevice </code> unless it is also the parent of <code> Hub </code> and therefore the <code> PC </code> . You should connect the phone directly to the other device, and access the phone over the network from the PC as Ryan says in his answer.

My HTC G2 running Android Gingerbread 2.3 randomly turns off while running applications such as the camera with full battery. After the random turn off I try to turn the phone on again and it won't turn on. I have to physically remove the battery, wait 30 seconds, put it back in, and turn on the phone to finally get it to work. Is there an app to prevent this or software update or do I need a new battery? PS: My previous phone, the Motorola Cliq w/ Android 2.1 and Motoblur also had this problem.

There is a known hardware issue with the HTC G2. Mine used to be hung at a black screen randomly when I tried to turn the screen on and unlock it. If your warranty hasn't already expired, start the process to get a replacement. The replacement I got hasn't experienced any of those issues.

How can I disassociate a device I don't have anymore from my Google Market account? This is a device that I used to have working but it's not anymore, so I don't want it to show up in my Google Market account.
|
There's currently no way to do this. It has been suggested numerous times on Google's forums, but has never been acted on. The best you can do for now is "hide" devices that you don't want to appear in the menus. You do this by logging into the Android Market website, then going to your account settings by clicking the gear icon and selecting "My Market Account" and then the "Settings" tab. On this page you should see a list of devices associated with your account. If you click the "Edit" button to the right of a device's name you can then select "Hidden in menus".

I have recently bought a used HTC Evo 3D from the internet. The phone itself is in perfectly working condition and the software is in its original state; that means it's not rooted, it's not running any custom rom and it's not branded. However, the previous owner seems to have installed many apps from the market, the launchers are kinda different and generally the phone is very 'customized and seems sloppy.' My question is: How do I get the device to its original, fresh, stock state? I don't want to install a custom ROM, I want to have the original android provided by the device manufacturer. I know the device has the "factory reset" option in the menus, however I don't know what it really does and how thorough it is. Wiping the phone and installing the system from scratch would be the best option for me, however, I don't know whether it's possible. What are my options here? Notes: I know what rooting is I know what custom ROMS are I can root the device if necessary, but I don't plan on doing so if not necessary Android 4.0 gets an official release for HTC Evo 3D soon - does this change anything related to what I need/want to do?
|
If it's not rooted and not running a custom ROM, a factory reset will reset everything back to stock and wipe the internal SD card. If you also wipe the external SD card, you will have a clean slate. Checkout Chapter Update and Reset , Section Resetting HTC EVO 3D , (Page 209) of the manual: http://www.htc.com/managed-assets/support/user-guide/user-manual/htc-evo-3d/110803_ShooterU_HTC_WWE_UM.pdf Quoting the manual: Resetting HTC EVO 3D Do a factory reset to return HTC EVO 3D to its original state before the first time you turned it on. If you’re passing HTC EVO 3D on to someone else or HTC EVO 3D has a persistent problem that cannot be solved, you can perform a factory reset (also called a hard reset). Factory reset is not a step to be taken lightly. It’ll permanently delete all your data and customized settings, and will remove any applications you’ve downloaded and installed. Be sure to back up any data and files you want to keep before you do a factory reset.

I've installed a malicious app that is posting ads over my notification bar, but can't find it. I know the java package name for it: <code> com.letang.game103.en </code> using the command: <code> adb shell dumpsys notification </code> . As you see the name of the app is not obvious from the package name. I want to find which app it is, that uses this package name. I also want to report them to Android Market, after leaving a nice feedback for them there! I've looked at different dumpsys commands: <code> adb shell dumpsys [something] </code> But so far wasn't able to get apps based on their package names. Is there any way to do this?
|
The easiest way, without using any specialised tools is just to visit that app's page in the Android Market. All apps in the Market have their package name as part of their URL, so you can just take your package name and prefix it with <code> https://market.android.com/details?id= </code> to get https://market.android.com/details?id=com.letang.game103.en Which will take you to the page for King Fighter Ⅱ by LeTang, Inc.

The rivalry between Google and Facebook seems to have gotten in the way of a really useful feature from Gingerbread: Facebook contact sync. Currently my Verizon Galaxy Nexus has the ability to add accounts for Google, Twitter, LinkedIn. There is even a Facebook entry in the add account list. However, clicking that does nothing. I see that in 4.0.3 there are new social contacts APIs that will let 3rd parties extend this feature with checkins and posts. Is there a way to enable Facebook contact syncing in ICS (with or without 4.0.3)?

I brought a new Samsung Galaxy Y inbuilt with Android 2.3.5 some month ago and sold it recently. But after selling I noticed that in that Android I left my email ID (email ID that is used to log in to android for the first time). I don't worry about the my email ID as I have changed its password but Can I locate my android device with that email? or by any other way? on any Google Maps like service?
|
No, you would need an application like " Where's My Droid " installed on the device and know the phone number for the device. If you sold the device, the new owner probably did a factory reset on the device so your information is no longer associated to the device. In the future, before you sell your device, you should go in and do a factory reset so you are not giving the device away with any of your information. I want to add my opinion on these apps that claim to help you find your device (including "Where's My Droid") if it is lost or stolen. They are great if you lost your phone in your house (or somewhere "safe") but if you lost it at like a bar or if someone actually stole it, chances are you will not even be able to use this software. A factory reset can be done on any device rather quickly, which would remove your "locating software" and remove any "tie" that your accounts may have to the device. Also, they require the device be ON, so if someone does steal your phone, all they have to do is turn it off, and when they have a chance, do a factory reset. My best advice I can give you is to remember that these are ~$600 devices (what you will pay off contract, or for a replacement) so treat it like it is a ~$600 device and don't leave it laying around. I am not saying that I would ever take someones phone or anything, but I could have the device factory reset by the time I got to the door to leave. It is as easy as <code> Menu -> Settings -> Privacy -> Factory Data Reset </code> .

I've got an HTC Evo Design 4G (Android 2.3.4), and I can't figure out how to clear localStorage in the browser. Clearing the cache, history, form data and everything else doesn't do it. Resetting the browser to default settings doesn't do it. The website (served from the local network) doesn't show up in Website settings either. The only thing that does work is deleting ALL data from the phone by resetting it to factory defaults. Is there an easier option, and how come this isn't done as part of clearing cache which should "clear locally cached content and databases"?
|
Try: <code> Settings </code> → <code> Applications </code> → <code> Manage Applications </code> → Select <code> Browser </code> (" <code> All apps </code> " tab) → <code> Clear Data </code> . This would delete all the data belonging to the app. Quite like a factory reset, but just for that app. Be careful while using this. Make sure you select the correct application (Its called ' <code> Browser </code> ' some phones and ' <code> Internet </code> ' on some) in the <code> All apps </code> list. You can accidentally delete your contacts and other important stuff if you are not careful

Let's say I buy an "un-rooted" Samsung Galaxy S2 via eBay that's still under warranty: Is there a way I can tell whether it has been rooted before (with or without rooting it myself)? Is there a way Samsung can tell me whether it has been rooted before?
|
Most Samsung Android phones and tablets can be restored back to "stock" firmware via Odin or Heimdal tools. This wipes all traces of rooting or any other kind of system alterations, and in most cases is sufficient for sending the device in for in-warranty servicing to the carrier of manufacturer. However, with the Galaxy S2 series of devices Samsung introduced a hidden "flash counter" which keeps track of how many times such a tool has been used. A community developer actually found where this information is stored and created an app that allows you to reset the counter. Unfortunately the app only works on ICS (Android 4.x) right now. See this thread on XDA-Developers forum for more details.

I have noticed a lot of vehicles that do not recognize any android devices but they do recognize iphones/ipods. This is something the manufacture has to add support for. These manufacturers usually use a proprietary system in the vehicle and they don't seem to think anyone uses anything besides an iphone or ipod. You may be able to use bluetooth to transmit the audio from your device to your vehicles stereo.

I'm having a problem with Picture Gallery not refreshing and loading too slowly on Android 2.3.4 Gingerbread (HTC G2). After I take a picture and then go to add it on foursquare or facebook from picture gallery, the last couple pictures taken aren't there. Sometimes the last 20 pictures taken aren't there or an entire directory of pictures isn't showing up. A lot of times it takes a long time to load the picture thumbnails and directories. Is there a way to refresh or fix the Picture Gallery or is there a better 3rd party picture gallery that you can recommend? Should I reformat or replace my micro SD card to make it work faster?

Sounds like the contents of your SD Card have not been scanned since taking the photos. Try the SDrescan app from Market. This should help in such situations. Alternatively, you can manually un-mount the SD Card (via <code> Menu -> Settings -> Storage -> Unmount SD Card </code> ) and re-mount it again. This should trigger the media scanner to refresh the card's contents.

I am having an issue with the time stamps of incoming SMS messages when backing up messages. The time stamps of the messages I send out are correct. The time stamps of the incoming messages in the backup files are 8 hours before the correct time. I read elsewhere that this can happen when you are roaming. I have a Motorola XPRT on Sprint and I live in California. I downloaded and used about 5 different SMS backup applications (both free and paid) to try to archive my messages. They all have this problem. Now here's the interesting part. The time stamps rendered in the stock SMS application are correct . I tried 2 third-party SMS applications with different results. Handcent SMS shows the time stamps correctly. Go SMS Pro show the incoming messages with the same incorrect time stamps as the backup files. This leads me to a point of reevaluation. The database that stores the messages on the phone is storing multiple time stamps. I'm guessing they have sent time (the time that is 8 hours behind what it should be) and received time fields. The backup applications and Go SMS Pro are probably using the sent times. The default SMS application and Handcent SMS are probably using the received times. Ok so now I need a way to solve this issue. To do that I need answers to some questions: Does Android use SQLite to store SMS messages? Where is the SMS database is located? How and where are MMS messages stored? How can I copy the database to my computer? Do I have to root my phone? How do I do that? Does doing this affect my warranty with Sprint? UPDATE: It looks this is a known problem where the time zone offset is applied 2 times instead of 1. There is a ticket for it here http://code.google.com/p/android/issues/detail?id=1305 . This ticket is more than 3 years old and is still open.
|
What timezone are you in? It sounds like when you back them up, it is saving them in a different Timezone (maybe UTC). to answer your other questions: Yes, SQLite is used for the messages <code> /data/data/com.android.providers.telephony/databases/mmssms.db </code> Same way as SMS messages : <code> /data/data/com.android.providers.telephony/databases/mmssms.db </code> You can use ADB from the android SDK and copy it to your PC by doing: <code> c:/android-sdk/tools/> adb pull /data/data/com.android.providers.telephony/databases/mmssms.db c:/users/my-account/desktop/mmssms.db </code> Yes, you will have to stackexchange-url ("root your phone") to get access to that directory. maybe check out SMS Backup + in the android market. It will backup your sms messages (doesn't do MMS yet) to your GMail account and put them in an SMS label. It will also restore them too.

Is there a way to use other lock-screens on the htc sensation then the one that is provided by htc sense without installing a custom rom? (rooting is fine) I would love to use the standard android lock-screens, is that possible? (I don't care if it is achieved with an app or by modifying the settings)
|
There are some "lock screens" like Go Locker , but they are not "real" lock screens. Lock screens are just about the only part of the android OS that cannot be replaced by 3rd party applications. These other lock screens attempt to override the real lock screen. Some of them work fairly well, but I always notice some type of lag when turning on the device or unlocking the device.

I don't have a lot of space on my phone (an HTC Aria). When I download an app from the market, I usually move it to SD immediately, but I've noticed that the "Internal space" amount doesn't change for a little while. I'm assuming that before installing the apk, it keeps a copy of it in a location on the internal drive, then garbage collects or cleans up the space sometime later. My question is, is there any way to force this cleanup?
|
You are completely right with your assumption: Whenever an app is installed, it is first copied to <code> /data/local </code> . You can check that directory if either you've got a file manager permitting you to go there, or have the Android SDK installed. No root needed, as this directory is readable and writable for the shell user. But to your last question: No, I'm not aware of any mechanism to control that delay (never saw a corresponding setting). If it can be configured (and is not hardcoded in some place), this will most likely involve root privileges.

The two ways I see to secure an Android phone is through a PIN lock screen or through an app lock program (Password is too inconvenient and pattern is insecure for stackexchange-url ("various reasons")). The lock screen has the advantage of keeping someone from the phone altogether, but an app lock program can allow me to use basic functionality while locking the apps that I choose such as Email or Package Installer. Is one option easier to hack/bypass than another? Let's assume that the App Lock program has a helper app that prevents it from being killed (although how well such an app works is worthy of being discussed in an answer - point being it takes a little more work than simply going to task manager and killing it). I am primarily concerned about data on the phone. I know that ultimately I cannot rely on either method to secure the phone indefinitely, but to only secure it long enough for me take various actions such as remote wipe, change Google password, Exchange password, etc... I'm running Gingerbread 2.3.6. For what it's worth it is rooted and has ClockWordMod recovery.
|
The app locker gives you more access, and is working against the system rather than with it. Almost by definition, it's much less secure. An app locker might keep out the casual user, but not anyone who knows what they're doing. Unless it blocks new apps by default, sideloading would be a problem. Depending on the device that may be enough to root it (if you're not already) and then they can more or less bypass/remove anything on the device. adb access is a risk in both cases but the ability to interact with the device may provide some other options. I agree with admartian that encryption is the way to go. Using a lock screen plus an app locker is better than using only one of them, as well.

I do not think you can view a log of some kind in the ui, however you can always manually sync and the icons show if it was successful. <code> Settings > Accounts & sync > Manage accounts > your account > OPTION BUTTON > Sync Now </code> this is in android gingerbread version You will see the spinning icons appear then disappear when synced, then you know :) I think I remember seeing widgets that sync your accounts in one click so it may be worth exploring the app markets.

I have allotted 1GB of space to my second <code> ext3 </code> partition, I have 2 doubts: Whenever I link my application, those space does not gets deducted from internal memory, I checked in Settings → Manage Application When I move the application to SD card, still I have some space occupied in internal memory I don't understand the exact use of Link2SD: if I allotted 1GB of space for the apps, then why my internal space is being used -- and if Link2SD does work like this only, then I would better use force move application using <code> adb shell </code> , which even does not require rooting. Can anyone please clarify my doubts, and let me know how can I use Link2SD , so that everything is moved to SD Card and nothing remains in internal memory?
|
An application files consist of apk, dex, lib and data files. Link2sd can only move the first three types of files to your SD card. Program like Google+ has huge data files so even after using link2sd they take up precious space of internal memory. When you move app to sd, only the apk file(in Android 2.2) and only the apk and lib files (in Android 2.3) are moved.

Google Talk is available for most Android versions, and in fact is pre-installed on all Google-authorised Android devices that have the Android Market and GMail installed (because both of those apps rely on Talk to do their authentication and communication). It may just be called "Talk" on your device rather than "Google Talk" or "Gtalk". If you're talking about Google Voice , then that app is available to all devices using Android 1.6 and higher, but you can currently only use the service within the US.

I would like to lock my phone with a pin for additional security. Also, I try to minimize my phone usage in the car, but in the event that I do need to call someone, I would like to be able to do so without having to enter a pin. I would like to do this by automated means if possible. I see two possible directions, but there could be others Use some third-party lockscreen app that supports pin/password/pattern while containing shortcuts to a few apps. I've seen lockscreens that have shortcuts to certain apps, but they don't provide a pin lock. Have a Car Home app that automatically launches when I plug in the headphones. Car Widget launches on headphone plugin, but it provides access to other screens as well, which I don't want. It has to be headphones though, I don't have a car dock or bluetooth or even a car power cable.

There are apps available that allow you to distinguish between locking your phone and it idling out . For example, it is a good security practice to have your phone lock whenever you hit the lock button, but understandable that you don't want it locking 10 seconds after you place it on the passenger seat. You can have the screen timeout after 20 seconds, but wait 120 seconds (or more, if you prefer) before it auto- locks . I know that Juice Defender provides such options. Some apps (such as the music app) have the ability of adding 'widgets' to your lock screen. This is even more apparent on custom ROMS (such as CyanogenMod ), which allow apps to respond to 'gestures' on the lockscreen.

|
I found this thread on xda-developers. If you have jail broken iPhone and rooted Android phone, you can transfer your progress. Basically you have to copy two files, highscores.lua and settings.lua from /private/var/mobile/Applications/(very long string)/Documents from iPhone and replace them on Android phone in /data/data/com.rovio.angrybirds/files/. You also have to fix permission and make sure you've completed at least 1 level in Android phone before replacing the two files. If you trust yourself you can also use programs like Angry birds unlock all level in Android and unlock only up to the level you've completed in iPhone. But you won't have exact score and hidden star collections. So though little troublesome the earlier way might be what you want.

I have about 8 gigs of music stored within Google Music, and I recently got sick of streaming (and risking data charges), so I painstakingly allowed it to be stored offline. So my fresh 16 gig SD card now only had 8 gigs left. Then, I flashed a new rom, thinking that all my music would still be there cached (or however it works), but I was wrong. When I click "show offline tracks only" within the Google Music app, it shows nothing, yet my SD card still only has 8 gigs of space left. So, my question is, where are these offline tracks stored on my SD card so I can go in and delete them, to free up space so I can back them all up again? Thanks! And also, why won't the app recognize that there is offline music stored on my SD card after a new rom is flashed? I figured that data would be untouched across roms.

The reason they don't appear when you install a new ROM is because the folder they're stored in contains a <code> .nomedia </code> file, which excludes it from the media scanner. Google Music is able to keep track of them because it puts entries into its database (which is at <code> /data/data/com.google.android.music/databases/music.db </code> ) which point to the file. Specifically, anything in the <code> MUSIC </code> table with a <code> LocalCopyType </code> value of 200 is a song on Google's servers which you've downloaded so it will be "available offline". This disappears if you wipe your <code> /data </code> partition when flashing a new ROM. If you have a <code> sqlite3 </code> binary on your device you can use the following to get a list of all songs that are available offline: <code> # sqlite3 /data/data/com.google.android.music/databases/music.db sqlite> select * from music where localcopytype = 200; </code> If you want to have your music stored locally across ROM installs, the easiest thing to do is just to create a folder at the root of your SD card named <code> Music </code> (or similar) and put the files in it. The media scanner will pick it up that way. Alternatively, you can try removing the <code> .nomedia </code> file from the Google Music cache folder. That should allow it be scanned, too, but I don't know if Google Music will try to re-create the file on subsequent launches of the app.

Yes many people experienced problems.

How do apps/games become featured in the Android Market?

As far as I know, they're simply picked by Google's staff. I'd assume they look for the general indicators of a quality app (good ratings, lots of active installs, etc) but popular or otherwise well-known developers probably have a leg up regardless. Google has never really come out and said "follow these guidelines", possibly to reduce people trying to game the system, similar to how they don't release their full page rank algorithm. However, I can definitely say that it is not possible to purchase your way into the featured list. Google's Android Market developer help page notes specifically: Featured and Editor's Choice apps are chosen by the Android Market editorial team. There is no paid promotional spots or advertisements on Android Market. Technically speaking, the only restriction I've seen is that your app must have a properly sized "featured" image to be used on the "Featured Apps" area. Aside from that, Google has been very mum about the process.

I am interested in learning how to write to (and if possible, read from) a rooted Android device's clipboard. I hope to do so using ADB over USB and I am not interested in installing any apps to help me do this, as this is something I plan on rarely doing. Any suggestions or help guiding me in the right direction would be greatly appreciated.
|
Yes, you actually can do this. It's kind of kludgy looking when you inspect the clipboard, but it works just fine. First off, you can inspect the current clipboard contents with <code> service call clipboard 1 </code> from an adb shell (or, without shelling in first, <code> adb shell service call clipboard 1 </code> ). It may start out initially blank after a reboot, for example: <code> # service call clipboard 1 Result: Parcel( 0x00000000: 00000000 00000001 00000000 00000000 '................' 0x00000010: 00000000 00000000 '........ ') # </code> You can put text into the clipboard using <code> service call clipboard 2 </code> , which basically takes 3 parameters - two ints and the string you want to put on the clipboard: <code> # service call clipboard 2 i32 1 i32 0 s16 "Hi there" Result: Parcel(00000000 '....') </code> To be honest, I'm not sure what the first two parameters are. stackexchange-url ("One answer on Stack Overflow") has suggested the first int is "number of items in the parcel" (one in this case) and that the second is the length of the string. However, I've used 0 for the second parameter and it works fine, and I can't find any documentation that matches up with this particular function...so take that for what it's worth. In any case, it's basically creating a Parcel object with 3 fields, then passing it into the clipboard. The clipboard then unpacks the Parcel and sets the string value passed in as the clipboard's contents. You can see this when you go to retrieve the value afterwards: <code> # service call clipboard 1 Result: Parcel( 0x00000000: 00000000 00000001 00000000 00000008 '................' 0x00000010: 00690048 00740020 00650068 00650072 'H.i. .t.h.e.r.e.' 0x00000020: 00000000 00000000 '........ ') # </code> Similarly, if you long-press on a text entry field and hit "Paste" after doing this, you will get the text that was set via the <code> call service clipboard 2 </code> line above (and it will look completely normal). (The above examples come from my HTC EVO, running CyanogenMod 7)

I've tried to plug my electric guitar into Toshiba Thrive tablet and record some music using the default Sound Recorder app. I found that the tablet recorded sounds as if the guitar is not attached to the tablet, there was a lot of noise and the guitar sound was not clear. When I plug my guitar to the sound card of the PC the sound produced is similar to what I hear when I plug the guitar to a real guitar amplifier; the sound is "clean" . I expected the same when plugging into the tablet. Is there a method to achieve the same clean sound on my Android tablet?
|
The info I'm finding suggests that you need a 4-ring TRRS connector to use a mic, and that the bundled Sound Recorder app will ignore this regardless and just use the internal mic, so you'll need a different recording app.

I've managed to get away with running my Galaxy S without every hooking it up to a Gmail account, but sometime in the last couple of weeks (I think following an OS update from Sprint) Maps started objecting that I'm not logged in. It's a little unnerving -- why do I need to be logged in to search for an address? I'd love any suggestions for getting around this. Happy to root my phone. I've got OSM installed, but it doesn't do address searches unless I'm missing something.
|
Your three options are probably: Downgrade Maps Use the browser-based Google maps (perhaps in incognito mode if you're paranoid) Use some other map application Regarding OSM, I think they don't have an official app, so you could also try to use an app that uses their data. The OSM web site allows address searches, so that may just not be implemented in the app you're using. There's a bunch of OSM compatible apps and their features listed here .

In Miui ROMs, there are four options for rebooting a phone from the power menu: What does "Hot Boot" mean, technically speaking? Are there any circumstances where a hot boot could cause harm? Are there any reasons for choosing to hot boot at all?
|
If it works like other "hot boot" apps and functions, then it basically restarts the Android GUI processes/threads. There was an XDA news post a while back after someone made an app for it where the app author described it as such: Hot reboot by rebooting only the graphical Android shell. From what I know it's sort of equivalent to restarting your X server in a Linux environment (like hitting CTRL + ALT + BACKSPACE , for example). I would definitely doubt that you'd cause any damage by restarting your graphical environment, especially considering other OSes do this pretty easily, but I suppose there's an outside chance if MIUI implements it strangely. Typically the reason people use a "hot boot" option is if the UI has somehow gotten sluggish and would benefit from a restart but they want to save time by not restarting the whole system (maybe a memory leak in the UI or something of that sort). It could also be useful if you need to restart the UI to apply some sort of change, like a theme perhaps.

I recently updated my Samsung GT-S5830 to Gingerbread via Kies. After the update my phone is displaying the kernel version as <code> 2.6.35.7-perf-CL5XXXXX root@DELL 142 #1 </code> . The <code> X </code> s are some 5 digit number. Im not sure if this is normal or if theres something wrong (because of the 'root'). Any clues?
|
I can see how you'd be confused by that. It doesn't indicate that your phone is rooted, just that the kernel was compiled by the root user (on a DELL build machine, apparently)! If you look at <code> /system/build.prop </code> (probably requires root to look, ha) you'll see some other similar information about the build. Mine says "jaeyoon.yoon@SEP-05" for the same info.

I am using connectify + proxy droid, yet only proxydroid seems to connect to the internet, while nothing else works. Proxydroid connects in the sense that, it loads ads. Nothing else works. I'm rooted. Is there any alternative way to set system wide proxy access? Nothing seems to be working. I tried autoproxy also. Help.

Hmmm. Did you definitely tick the 'Transparent Proxy' option? That tells it to make everything go through the proxy. Another thing I have noticed when using it is that it can be quite specific with a proxy - my school uses microsoft tmg, and has the proxy as 'tmg' in browsers, but proxydroid needs the full URL to the system (which is TMG.academy.(myschoolwebsiteurl).co.uk)

I am making application that is using .pls files to read shoutcasts' adresses from them. At one moment I noticed, that sometimes .pls file I was reading data from is disappearing after I have used it. After lots of testing, I noticed, that if I rename file to .txt, it won't get deleted. A little more testing, a voila - sometimes, if I read data from one .pls file (pathname provided in String), ALL .pls files on sdcard get deleted! And my doing anything with any of them - they just all get deleted. I am using HTC Desire Z, Android 2.3.3, not rooted, and I don't remember installing any applications that could be deleting files, especially without my knowledge. Any ideas? I can provide you with the app code I am using, but I don't really think it is connected in anyway to this problem.
|
Now, I am not 100% that this is the exact issue, as I do know that this is the stackexchange-url ("case with .m3u") playlists, but I have not tried using .pls files for a playlist. The problem sounds like it is with the Media Scanner. When it scans the directory that the .pls file is in, it sees the playlist file (the .pls) but if the directory does not have any other media files in there (like .mp3 for example) then it automatically assumes that the playlist is empty so it deletes it. You can create a file in the directory called <code> .nomedia </code> and the Media Scanner will not even scan the directory, leaving your .pls files alone. To test this, you could just drop some type of media file in the directory with the .pls and see if it is still deleted (or add the .nomedia file). If it is not deleted, then it is 100% the Media Scanner causing the files to delete. If it is still deleted, then I would check if in your application you are deleting them some how.

The procedure for porting a SIM card from a pay-as-you-go phone to an iPhone 4 is well documented ( example 1 , example 2 , config tool for iOS 5 ). This is a nice option for people mostly on WiFi who use a small number of minutes (or VoIP), because with AT&T GoPhone plans, you can keep network costs down toward $100/year. Is there a similar procedure for porting to a high-end Android phone? For example, can you buy a $3 GoPhone from Best Buy, buy an unlocked or AT&T Samsung Galaxy S II off eBay, move the SIM card into the Galaxy, and expect it to work? Other than ensuring the GoPhone plan has a data bundle feature, what other configuration is required?
|
If you have an unlocked phone, I don't think there should be any problem. The SIM card for GoPhone is apparently just a regular prepaid SIM card and is not tied to the phone it is sold with. If the phone doesn't recognize the APN for 3G, just go to <code> Settings > Wireless and Networks > Mobile Networks > Access point Names </code> and enter the appropriate access point settings manually.

I would like to run emacs on my android phone. Has anyone done this? If so, how can I? I've looked, and I haven't been able to find either an executable or instructions to compile emacs for android. I know cyanogenmod has some unix commands, but I haven't found a list or whether it includes emacs. I don't want to flash my phone without knowing. I've seen many pages on running emacs on "android" via installing Ubuntu. I don't mean running emacs on "android" hardware, I mean running emacs on the android operating system. I'm also aware I can use an app to SSH to a unix box, and that there are online emacs emulators. Again, not what I'm looking for. I'm looking for the standard command-line GNU emacs, and I'm aware I'll need to use a terminal emulator app to run it, as well as a bluetooth keyboard to do anything useful. I'm not looking for a GUI app, though that would be better than nothing. I'll accept either a link to a binary, or instructions to compile it.

Using the following diagram from developer.android.com you can see where it falls in the specs: It's 3 inches diagonally - it falls in the "small" category. It's 133ppi - which is definitely ldpi.

I don't know if this is standard ICS behavior or if it's due to my Cyanogenmod based ROM, but every time I open the soft keyboard by clicking on a text box/area a notification appears in the notification drawer that says "Select input method." I don't mind seeing this notification one time, but I'm already using the input method I want and I'd like to disable the notification. Is this standard behavior for Ice Cream Sandwich? Can it be disabled?
|
This is a standard 'feature' of ICS. Aside from the notification, changing input methods can be accomplished through the "language and input" section of the phone menu. If you disable and uninstall all keyboards except for one, so there is nothing else to switch to, the notification may disappear.

I have a handful of Galaxy Tab 10.1 (P7510) running Honeycomb, and a customer commercial application which runs beautifully on Froyo and Gingerbread, but has bugs on both Honeycomb and ICS. Before I chuck thousands of pounds worth of hardware away and settle for running my app on smaller tablets, is there a sane downgrade path to 2.2/2.3 for the P7510? I have some 7" Galaxy Tabs if these would be a useful source of ROM images, for instance.
|
No, the key parts of the ROM would be the kernel and all the drivers for the hardware. The boot image is likely different too. These devices are not the same so you would end up, at the very least, "soft bricking" your device. Even when a device is basically the same, take all of the Galaxy S devices (vibrant, captivate, facinate, epic, i9000), all are basically the same device, but you cannot "cross flash" the ROMs between them. This is because the smallest change in hardware or boot image prevents this.
