In the Amazon Appstore settings, there is a preference to enable <code> Parental Controls </code> . When set, this causes all apps (that are installed via amazon appstore) to require the amazon password before being able to make an in-app purchase. You can also specify an optional PIN to use in lieu of the full amazon password. According to the details, this only affects in-app purchases, and it does not hide 'mature' apps or enable any filtering. Another setting is <code> In-App Purchasing </code> . This preference is active by default, but it can be disabled to completely remove the possibility of in-app purchases. By default, no password is needed for in-app purchases, and the in-app purchasing ability is active. For both of these permissions, you are required to enter your amazon password to change the permission. My question is this: If I disable in-app purchasing completely, is there a need to also enable parental controls? Since the preference itself cannot be altered without typing in the password, I feel like the Parental Control preference is redundant for my purposes.
|
In short, you are correct. Disabling in-app purchasing completely via <code> In App Purchasing </code> option makes password-protecting under the <code> Parental Controls </code> settings redundant. It's definitely confusing, and could have been better accomplished by having just one setting with 3 options: Disable, Allow, Allow with a Password. It's possible that these two settings used to work differently on older versions of this app, and developers decided that keeping the settings separate would be less confusing to existing users than combining them.

So obviously I can't just "swap the SD card" as neither the old phone nor the new phone have an SD card slot. Similarly I don't really want to copy everything across from the old phone, so I don't want to use titanium backup and root. I just want the "standard" stuff transfered: mainly images, but maybe text messages and such as well. Is there any way to do this short of literally plugging the phone into a computer and transferring them manually? Thanks.

Sync should take care of contacts and most settings on your phone. Download SMS Backup and Restore on both phones, backup on Nexus S and send the backup xml file to N4 (via Bluetooth or wifi hotspot) for restoration. For transferring files between the devices, you can use the wifi hotspot functionality. Works real fast. I'm not sure if it is available on Nexus 4 (being a newer, better phone, I presume it is), but I have it on my Nexus S and have used it to transfer files from a Galaxy S2. Update: AnySend seems like a useful app to send files between two devices. The only requirement is that both have to be connected to the same wifi network.

Most of the mobile manufacturers include a hidden service menu in their mobile handsets. These menus allow users (or developers) to access some technical information and service personnel to access service details etc. Is there a similar service menu for android devices and What can I do with that menu?
|
Well, there is a menu available for handsets running android OS. To get the menu, go to your stock phone app and type the following. <code> **#*#7378423#*#* </code> It is simply <code> *#*#SERVICE#*#* </code> There are many things you can do in this menu. View service information Check service settings Carryout service tests Reset customization settings Some of these items may differ from handset to handset. These are the typical menu items available. This menu comes handy when checking the total call timer (in <code> service tests </code> ), Rooting status check (in <code> Service info -> Configuration </code> ), etc.

I'm using Jelly Bean on a tablet and a phone on the same account. After logging into a particular wifi network on one device, I noticed that sometime later (weeks) the other device had some acquired the settings (including password) and logged into the wifi automatically. I was unaware that android had a form of wifi profile sync. Is there any information out there about this functionality? How does it work? What other data is sync'd between devices?
|
If you go to <code> Settings -> Backup & reset </code> there is a <code> Back up my data </code> option which states: Back up application data, Wi-Fi passwords , and other settings to Google servers In addition to this on the Android OS support site it says: a wide variety of your personal data is backed up autonmatically, including your Wi-Fi passwords, Browser bookmarks, a list of the apps you’ve installed on Google Play, the words you’ve added to the dictionary used by the onscreen keyboard, and most of your customized settings. Some third-party apps may also take advantage of this feature, so you can restore your data if you reinstall an app. If you uncheck this option, your data stops getting backed up, and any existing backups are deleted from Google servers. As for the security concerns although I assume they must be sending plain-text WiFi passwords according to the Backup Service developer guide they're at least using a secure connection to do it over.

What is the difference between a "managed in-app product" and an in-app product that is not managed?
|
The short answer is that managed items are items that can only be purchased once per user and that Google Play keeps track of their purchase, unmanaged items aren't tracked by Google Play and they can be purchased multiple times. A fuller description is given in Google's In-app Billing Version 2 : Managed per user account — Items that can be purchased only once per user account on Google Play. When a user purchases an item that uses the "managed per user account" product type, Google Play permanently stores the transaction information for each item on a per-user basis. This enables you to later query Google Play to restore the state of the items a specific user has purchased. If a user attempts to purchase a managed item that has already been purchased, Google Play prevents the user from purchasing the item again and displays an "Item already purchased" error. The "managed" product type is useful if you are selling items such as game levels or application features. These items are not transient and usually need to be restored whenever a user reinstalls your application, wipes the data on their device, or installs your application on a new device. Unmanaged — Items that do not have their transaction information stored on Google Play. This means that you cannot later query Google Play to retrieve transaction information for those items. For "unmanaged" purchases, you are responsible for managing the transaction information. Also, Google Play does not attempt to prevent the user from purchasing an item multiple times if it uses the "unmanaged" product type. It's up to you to control how many times an unmanaged item can be purchased. The "unmanaged" product type is useful if you are selling consumable items, such as fuel or magic spells. These items are consumed within your application and are usually purchased multiple times. Note that only version 2 of the in-app billing deals with both managed and unmanaged, version 3 only deals with the managed in-app product type .

I'm attempting to install the exynos fix after downloading the .apk file. When I open the file to run, the system tells me that I cannot install apps that did not originate from Google Play. After some googling I found an article that shows a workaround , however when I go to: <code> Home → Settings → Applications </code> I see a list of applications and memory usage.

I have a Samsung Galaxy S3 and was wondering if it's possible (like on Blackberry) to setup a schedule for automatic device shutdown. For example, on my previous phone, I could indicate for the phone to auto shutdown at 12AM and auto turn on at 7AM. Is it possible on Android without download third-party app?
|
Natively, there is no way to schedule shutdowns and boot ups of the Android system. If you do decide to root there are applications in the Play store that can shedule a shutdown (you may even be able to make your own busybox script instead). However booting up will never be possible the way Android handles shut downs because when Android shuts down, it is not running.And so, there is nothing in memory to initiate any sort of startup process.

I keep my media files (such as music) on my home server. When I add a new album to the home server, and want to copy it to my Android 4.0.4 phone, I use a Samba client (such as AndSMB or X-plore) to copy the files to the phone. So far, so good. The problem is that the images in subdirectories that I copy over (such as album art) automatically get added to the gallery during the copy, although the root directory I'm copying into has a <code> .nomedia </code> file in it. If I start the copy, then check the Gallery app mid-copy, I see the images start to appear before I run any other apps. I don't want the images to appear in the gallery. If I "clear data" for the Media Storage app, then reboot, the gallery is rebuilt without the album art images, so the <code> .nomedia </code> file does seem to be doing its job some of the time. Is there a way I can copy media files to my phone over a network, without them automatically getting added to the gallery? Clearing the data in Media Storage and rebooting the phone works, but is tiresome and has other unwanted side effects like resetting my ringtones.

Is there a way I can copy media files to my phone over a network, without them automatically getting added to the gallery? I don't think it's possible. After some googling I found this info: 1) Hide Album Art from Gallery And the provided solution: I have all of my photos named folder.jpg/jpeg (I forget which extension) and they don't show up in the gallery. 2) [HOWTO] Make gallery remove album covers So I did this: Add .nomedia in my music directory, eg. "Music" (only on top directory). Rename "Music" directory to "Musicc" Run Gallery, exit. Rename "Musicc" back to "Music" Run gallery and thebthumbnails no longer appear. Also works with other directories that has thumbnails in gallery and adding .nomedia later. In my case the thumbs are still displayed. Also take a look at this post: How to Exclude Unwanted Images from Phone Gallery on Android Gallery Excluder is a dedicated Android application which removes the folders that you want to exclude its showing in the default Android stock version. This application is quite simple and does the job what it says with the application name. So if you have folders which you don’t wants to show it on your Gallery then install this application, select the folder which you want to show and done.

I need to run a <code> configure </code> file into my android phone so I think the best way to do this is to use the <code> adb shell </code> command. I'm running an Android emulator onto a Windows-7 platform, and there I'm running the <code> adb shell </code> command into a DOS window. Using the <code> cd </code> command I'm changing to the directory where my <code> configure </code> file is, and then I'm executing the following command: <code> ./configure </code> . I'm getting the following error : <code> ./configure: permission denied </code> So I try to run adb in root mode with <code> adb root </code> -- but apparently my adb is already in root mode (Moreover I have the "#" character before each line of my adb shell). I have also tried to use <code> chmod </code> but I don't see any difference before and after executing this command ( <code> ls -la </code> ), so maybe the problem is here (How can I run the <code> chmod </code> command?). Maybe someone here can help me with my issue, and if you have also an explanation about why I don't have the permission to run my <code> configure </code> file it will be great. Thanks. PS: My goal here is to use the net-snmp package on an Android platform by compiling the sources of this project directly onto the platform.
|
This is due to 2 things: The file does not have execute permissions [AND] The file cannot gain executable permissions as it is on the SD Card. The SD Card's filesystem can accept file permissions, however it is mounted with the <code> noexec </code> flag, as stated in a comment. This stops files being executed. Solution: Copy the <code> net-snmp-5.7.2 </code> directory to the <code> /data/local/tmp </code> directory as root. Set the <code> configure </code> file to be executable by running <code> chmod 0777 /data/local/tmp/net-snmp-5.7.2/configure </code> as root. You should now be able to execute the configure script by typing <code> /data/local/tmp/net-snmp-5.7.2/configure </code> and pressing enter. Note This should all be done as the root user :)

I use Android 4.0.4 (Cyanogenmod) and I have the habit of disabling automatic updates for all my apps. I have noticed the Google Play app seems to update itself automatically -- when there are updates for any other app, I'm shown a notification mesage from the Google Play app, and I have to use it in order to update the app. But when there are updates for Google Play, it seems to autoupdate itself. Is it true? Is there a way to disable this?

According to the Section 3 of the Google Play Terms of Service you consent to Automatic Updates: Updates. You may need to install updates to Google Play or related Google software that we introduce from time to time to use Google Play and to access or download Products. Products originating from Google may communicate with Google servers from time to time to check for available updates to the Products and to the functionality of Google Play, such as bug fixes, patches, enhanced functions, missing plug-ins and new versions (collectively, "Updates"). By using the Google Play store and installing these Products, you agree to such automatically requested and received Updates. *Bolding added for emphasis.

I'm trying to partition my external SD card (32GB SDHC), so I can link application to the second partition with link2sd. Now the problem is that, no matter what filesystem I use, link2sd can't create the mount script/fails to mount. I tried FAT32, FAT16, ext2, ext3 and ext4. Same result everytime, I tried formatting it with MiniTool Partition Wizard and ClockworkMod Recovery. I made the first Partition a FAT32 primary and the second partition an put in filesystem here primary partition. I also tried diffrent sizes between 256MB and 4GB. I'm on Cyanogenmod 10 running on an Samsung Galaxy Ace (I-5380).

Ok the problem was simple and stupid. SuperSU had denied link2sd its root access permanently, I must have clicked on denied once... Enabled root access for link2sd and everything was working fine.

So I'm on a Galaxy Nexus. Still on 4.1. I tried the 'hack' where you clear data on the Google Services Framework, then check update, but no luck. I shrugged and got on with my day. Now I'm noticing that I have several updates in the play store. And if I choose "update" all I get is an instant "Update for [app name] could not be downloaded". Repeatedly. I've tried clearing data for the play store, rebooting, but nothing. Yay. Any theories?

On Samsung Galaxy 2 is there a way to set volumes for the radio and incoming calls separately from each other? What's too laud for the radio (for me anything above 3) is not loud enough for the incoming calls, which results in me missing calls.

If everything else fails (and your comment above says you cannot set the volumes separately as needed), you could take a look at Volume Ace , which not only allows you to set all volumes separately 1 , but even lets you create profiles 3 switchable via widgets 2 : This enables you to always have the right volume settings according to the situation.

I recently bought a Nexus 4 and I would like to transfer my photos of my previous device to it. My previous Android phone used the standard USB mass storage which gave 0 problems to copy back and forth stuff, but the Nexus 4, like many other modern Android phones I suppose, uses MTP instead, which has the interesting feature of refusing to copy the original dates/timestamps of the files, using instead the date at which the files are being copied. This is obviously a huge bummer when it comes to photos; not only because one cannot check the original date at which the picture was taken while browsing on the phone, but also because they end up completely unsorted. Is there a way to transfer photos to a Jelly Bean Android phone that doesn't support USB mass storage preserving the original timestamps? Things I've tried so far: Transferring via USB MTP ADB push (both full folders and individual files) Transferring via SSH (using SSHDroid + WinSCP) Uploading and downloading from Dropbox Transferring a ZIP file via MTP and uncompress the file on the phone Transferring from the other phone via bluetooth QuickPic "fix date" function Local Sync Photo Date Correction FTPSyncX Smoke signals Yelling at the phone None of them preserved the timestamp, and this is driving me insane. (Also, I am not rooted yet, but if the only viable way requires root I would welcome that answer as well.)
|
You can't, this is a current permission problem (bugreport here) of Android 4.0+'s /sdcard folder if it's not using FAT32 (but FUSE). Reason: There's a transition away from FAT32 to unified user storage for both apps and media data (using ext4) on a single file system. We got tired of seeing OEMs include many GB of internal storage for music, while users were still running out of space for apps and data. This approach lets us merge everything on one volume, which is way better. -- Dan Morrill, Android engineer at Google The old FAT32 properties are emulated using a FUSE layer to be compatible with existing apps. Also: /data/ and /sdcard on Google devices starting with the Nexus 7 use a single partition only (/data/media represents the "sdcard" content and is exposed using the FUSE layer to apps). Here's CyanogenMod's implementation of the FUSE driver if you're interested in seeing the source. Looks like setting timestamp attributes is implemented, though. EDIT: It only works with root. Exact reason: All files are owned by root.sdcard_rw (see here). A caller withouth uid=0 can't call the utimensat() syscall, it fails in the VFS layer already (EPERM) for timestamps other than current: the caller's effective user ID must match the owner of the file; or the caller must have appropriate privileges. To make any change other than setting both timestamps to the current time (i.e., times is not NULL, and both tv_nsec fields are not UTIME_NOW and both tv_nsec fields are not UTIME_OMIT), either condition 2 or 3 above must apply.

I know multi-user functionality is available in Android 4.2 JellyBean: I have gone through THIS and THIS . But I want to test this feature on my emulator and not on the actual device. My Questions: Is it possible to test multi-user feature on an emulator? If yes, how it can be?
|
The Android emulator doesn't currently support this, unfortunately. There is a configuration file in the build system that determines whether or not to enable the user accounts feature, and it is disabled in the emulator images distributed by Google. You can star this issue on the bug tracker in the meantime. However there are two alternatives you can look at: You can alter the configuration file and build a new emulator image from the AOSP source and use that in place of the system image that the AVD uses by default. The file in question is in <code> /frameworks/base/core/res/res/values/config.xml </code> within the Android source. There should be an option named <code> config_multiuserMaximumUsers </code> which needs to be set to a value greater than 1. You can try the Jar of Beans emulator package. It has experimental support for multiple user accounts. Note, however, that this is an x86 emulator, not an ARM one.

I have some items in my ubuntu 12.04 desktop. I want to transfer them into the Sdcard of one of the avds in my android emulator (android-sdk-linux) which I have installed on the same system. Like to know how to do the above.
|
1. Using command line: Here's how you can copy files to an SD card image . You have to use <code> adb push </code> to copy files from Desktop to Emulator and <code> adb pull </code> for the reverse. Here's the syntax to copy files to or from an Emulator/Device Instance : Copy from desktop to emulator: <code> adb push <local> <remote> </code> Copy from emulator to desktop: <code> adb pull <remote> <local> </code> Here <code> <local> </code> is path of file / folder on your desktop and <code> <remote> </code> is path of file / folder on your emulator. Here is an example: <code> adb push foo.txt /sdcard/foo.txt </code> foo.txt will be pushed (copied) to the emulator. 2. Using DDMS UI: Here's how to work with emulator's file system using DDMS . In the Devices tab, select the emulator that you want to view the file system for. To copy a file from the device, locate the file in the File Explorer and click the Pull file button. To copy a file to the device, click the Push file button on the File Explorer tab. I personally prefer the adb pull and adb push commands as you can copy multiple files (in a single directory) with just one line command, using DDMS you can copy only one file at a time (no directory).

I have a 32 GB Nexus 7 (idVendor = 18d1, idProduct = 4e41, if that helps...), and my laptop runs Ubuntu 12.10, and have tried connecting using K.K. Patel's answer here, to almost no avail. What happens is that the "GalaxyNexus" folder is created, and then when I try to navigate to it, it has two sub-folders "Playlists", and "Internal Storage" (I cannot add a file or folder here, which is the first point of concern). When I navigate to "Playlists", the folder opens to a nice blank screen and I guess that's to be expected (I haven't been able to put music onto it yet). When I try to open the "Internal Storage" folder, it opens a new window that is the same as the first ("Playlists", "Internal Storage"). So I tried going in through the terminal to a similar fate. Anyone experienced this problem and/or know what to do to fix it? I really just want to be able to transfer files to the device.

Jelly Bean devices do not use USB Mass Storage to mount themselves on PCs. They use the more secure MTP method, and Ubuntu does not natively support MTP. The method you have linked to is the only official way to do what you want. I own a Nexus 7, but I am using a custom ROM, and as such, USB Mass Storage is hacked into my build. However, I believe on the stock ROM, if you check in Storage and you press Menu, you should have an option to set the USB connection type, and there is a Picture Transfer mode. It won't let you see all of the files on your Nexus, but it will allow you to copy and it shouldn't need any extra help inside Ubuntu. For an extremely detailed explanation on MTP and why it exists, and why on the stock ROM you will never be able to use it as a flash drive, I highly recommend you check this StackExchange question: stackexchange-url ("How can I use my Galaxy Nexus as an external USB storage drive?")

I am getting rather low battery life when using auto-sync on 3G. I have wifi in college and at home, so I'm looking for a way to enable auto sync only when connected to those 2 specific wifi networks.

That's easily accomplished using Tasker . If you don't know, Tasker is the most complete automation solution for Android. It doesn't come for free (5 Euro -- but you can get a free trial on their homepage), but is definitly worth the price. Just take a look at the Tasker UserGuide for a full description. Tasker combines conditions and tasks to profiles. In your case, the Task would be something like: Task AutoSync: Auto-Sync: On You will have two Conditions , one for each profile ( Tasker always connects conditions by AND, so you need two different profiles: Profile Home: Condition: Wifi Connected (add your home network's details) Task: AutoSync Profile College: Condition: Wifi Connected (add your college's network's details) Task: AutoSync Now, when you're not connected to any of these networks, switch off AutoSync manually once (you won't have to repeat this). Next time you connect to one of the two networks, Tasker turns AutoSync on -- and resets it to the previous state (off) as soon as you are disconnected. If Tasker is too heavy for you, I'm pretty sure there are other automating tools which can accomplish this simple task ( Llama - Location Profiles for example). But now that you've got the idea, you will find the related app fitting you.

I was wondering, if I have an app that is available on the Play Store, is it "safe" to provide a direct download of the apk file to someone (either signed with the proper keys, or just debug-version)? "safe" in the sense of does the marketplace do anything special to the apk to protect the source code, signing keys, etc.? Reason I ask is a user of my app has said that their Marketplace/Play Store is no longer working and therefore can not upgrade the app - so asked me to email them the apk file. The app is a free app, so on the surface I can't see any issues - though just wanted to double check. Although this raises the question - the apks of the apps you download from the marketplace (paid and unpaid) are on your phone. Are these apks (on the phone) somehow unique to the phone/google account? Otherwise, what stops one from buying an app and passing that apk on to others?
|
There is nothing dangerous about it, and this is done occasionally when the store isn't accessible. In response to your second question, apks are not unique - and can be easily transferred to another device, or the internet. This is the base of android app piracy. When you upload the APK to Google Play, GPlay does nothing to it. It is up to the developer to obfuscate the code, to prevent decompilation.

I've never seen this before so I'm assuming that it happened when I upgraded to 4.2: I'm fairly certain that <code> /sdcard/ </code> used to take me straight to my sdcard, but now when I go to that path (in CWM recovery for example) I need to go to <code> /sdcard/0 </code> , there's also <code> /sdcard/legacy </code> knocking about suddenly. What are these folders and why have they appeared?
|
That has to do with the Multi-User feature enabled with JellyBean 4.2 (not 4.1). In order to handle separate accounts, parts of the directory structure had to be changed. <code> /sdcard/legacy </code> e.g. always points to the currently logged-in user's sd card directory. I currently cannot find the document where I read the details, so I cannot link any source. But with the above in mind, it's easy to guess that <code> /sdcard/0 </code> will most-likely be the device owners (or "first users" -- the "first user" always becomed the "device owner", only this user can create additional accounts) sd card, and so on. I will add a link to a source as soon as I can find it. EDIT: One of the pages I got that idea from is AndroidNext. 1droid gives a different explanation when it comes to sd card: With Android 4.2, Google introduced multiple users as a new feature. In order to accommodate multiple users, Google is now giving each user a their own folder for storage. If you upgraded to 4.2 from 4.1, then the 4.2 ROM will look for a certain file in /data to determine whether it needs to migrate all of your files to the new multi-user data structure. By default, 4.2 migrates all of /data/media to /data/media/0. A problem arose though with custom recoveries. A custom recovery retains the /data/media folder during a factory reset. When you factory reset and then boot a 4.2 ROM again, the 4.2 ROM will migrate everything in /data/media again. It will migrate your files every time you factory reset. This multiple migration is what resulted in some people having their files moved to /sdcard/0 or even /sdcard/0/0 etc. So it has in fact to do with the new Multi-User feature -- one way or the other.

Why did /sdcard/ turn into /sdcard/0/ with 4.2?

When clicking on Phone -> Logs, I have hundreds of contacts presumably from Gmail. Is there a way to hide all google contacts, and only show ones I've manually entered (SIM or other storage)? I'd like to only see contacts with phone numbers when using the Phone. My phone is a S2 (Tmobile), if it matters.
|
You have not mentioned your Android version, if it is Android 4.0+, I fear you cannot do this. There's no option to show contacts with phone numbers only in <code> People </code> app that is included in 4.0+. If you are on GingerBread or earlier versions, you have a setting something like this: <code> Contacts app - > Menu -> Display Options -> Only contacts with phone numbers </code> I am talking about stock Android apps, your manufacturer / ROM builder may have a tweak depending on what ROM are you running. I don't see a chance, but still a possibility. See this stackexchange-url ("similar question").

I've installed a task manager widget that shows me the amount of free memory I currently have in the icon of the widget. When I look at it it updates every ~3 seconds, so it definitely drains some battery and consumes some memory when it's active and updating. I want to make sure it doesn't update when the widget is invisible: When screen is turned off. When another app is running. When widget is placed on another (invisible) home screen tab. How can I check whether the widget updates only when it's visible or even when it's invisible?
|
It doesn't update only when it's visible. Because all widgets are drawn by the host (i.e. the home screen or lock screen), there's no way for the widget provider to tell whether the widget is visible or not. It would be possible for the service that keeps changing the widget to find out when the screen is turned off. In recent Android versions, you could verify that using the Battery screen in Settings . Add the widget to your home screen, then (while the phone/tablet isn't plugged in) leave the screen turned off for some time. Turn it back on, and see if your task manager app is listed on the Battery screen. Regardless of the result, your task manager app is probably doing more harm than good. Android isn't like Windows: it's designed to keep as much memory in use as it can, and only frees memory when it has to. See stackexchange-url ("Do I really need to install a task manager?") for more info.

So first, when I go to Settings -> Apps this is what is shown: (Click image to enlarge) After some time ~20 seconds, the amount of space left is this: (Click image to enlarge) Why does this happen? What does this mean? And when installing any Android app I always get the insufficient storage space error. Why? When determining the amount of space that is free, which of the two screenshots' storage space does the Android OS consider? Anyhow, in both the cases the minimum that I had was 40MB and the app that I wanted to install was 12MB , yet I got the error. I am running on HTC Legend, Android 4.1 Please clear this confusion. Thanks!
|
Your confusion is most likely caused by the way the Playstore handles installs/updates. They are first downloaded and stored in internal storage (not on sdcard, but <code> /data/local </code> ), then the app is to be installed on the same partition ( <code> /data/data/app.package.name </code> ) -- only after that the download can be deleted. In your case, this would mean a 12M download, which then needs to be unpacked (at least another 12M, or rather more) -- which could sum up to 30M or more. A safety margin needs to be kept to keep the device from crashing -- so you get the "insufficient storage" error. See also: stackexchange-url ("Package Install via Market sometimes fails and gives seemingly random error message")

Ever since I upgraded my Google+ app on Friday (3.3.0.40049528) one of my favorite features, Image Instant Upload, is not working. One of the big changes in this release was that instant upload could now upload full size images, rather than limiting them to 2048px. I have plenty of available storage (4GB out of 5GB available) I have force stopped the Google+ app as well as cleared the data at least once The phone (Verizon Galaxy Nexus) has been restarted a couple of times I am using the stock camera app for my testing The settings were not changed when I updated Google+, but I have confirmed that Instant Upload is set to allow photo uploads on wifi as well as mobile data. I do not have "upload only when charging" turned on, and there is plenty of battery available. Any ideas? Have I got a bug that needs an update?
|
In <code> Settings->Accounts and Sync->Your Google Account </code> make sure Google Photos is selected This is in <code> Settings->Google </code> in 4.x. EDIT: I just checked, and reinstalling the Google+ all fixed this. Uninstall the app, then install it again. You then need to go into the settings menu and enable instant upload.

I can't take screenshots on my rooted Android 4.0.3 tablet. It's a Genesis GT-1230 running some modified ROM, and apparently the power + volume down combination is disabled. The screen is 10.1", 1024 x 600 pixels. I have GoLauncher installed on it, and its screenshot feature produces a result like this: (resolution 600 x 988, not resized or edited in any way) However, if I deny root permissions for GoLauncher, the screenshot result goes like this: (resolution 249 x 410, not resized or edited in any way) I installed this screenshot app , it requires root, I give root permission, and it displays an error message, something along the lines of " error on fb0 ".
|
I was able to take screenshots after rebooting the device and running the same screenshot app with root permissions. The GoLauncher screenshot feature gives the same results, corrupt image when ran as root and very small image when ran as non-root.

I used to use - and loved - LBE Privacy Guard which allowed you to revoke specific permissions from specific apps. Ever since AT&T finally pushed out Jelly Bean for the S3 though, it no longer works, and puts my phone into a endless reboot loop. Searching in the market, I couldn't find any other app that does this (though the are plenty that just let you SEE the permissions of all your apps). Anyone know of another app that does the same thing as LBE?
|
LBE works on JellyBean -- just not the version you install from the Playstore. The boot-loop problem is a known issue (so nobody can understand why the developer did not even place a note on the app's playstore page). On XDA you can find multiple threads discussing this issue, and at least one of them also holds modified versions of LBE to download. Take e.g. a look at: [APP] LBE Security Manager v4.3.2738 (this is a new version only released in Chinese -- but some XDA members provide a translated version here) [APP][ROOT] LBE Privacy Guard - Most Powerful privacy protection app for Android [APP] LBE Privacy Guard v2 is now available Alternatives to LBE would include: PDroid Privacy Protection PDroid Manager (Open-Source alternative to it)

I want to get a call from somebody and after talking with him redirect that person to another number, on my charge, like call-centers do. Is that possible and if that's so, there is any application that can do that? Thanks
|
I guess you could do this using the " Conference Call " trick on android (natively!). The screenshots below are for vanilla Froyo (Android 2.2) and may vary with your version/dialer app. During your call (Don't hang up the call), after talking to that person, press the "Menu" button on your android. Press "Add Call" from the menu. Dial and call the number you wish to "redirect" for him. (on your charge! (which is what you asked for right?) Means you will lose money for this call as if you are calling it) Now press menu button again when call connects. Press on "merge call". Finally, Press the menu button again and click on "mute" to make them think you have terminated your call. (you mute yourself but you can hear the conversation between him and the "redirected" call) Remember, while doing these, you will be charged for 2 calls simultaneously!

This is in reference to my stackexchange-url ("other question.") My phone was not working so I showed it to service center guy and he said the motherboard is broken and needs to be replaced. I can flash custom ROMs to the phone but they are not also booting up. So I just want to confirm does that really mean my motherboard is broken and needs to be replaced?
|
If it starts to boot (goes to the boot logo/animation) or Recovery/Download mode at least tries to load, then the motherboard is NOT damaged. Your device is soft-bricked, and just needs to have a compatible ROM flashed, and your userdata erased for your device to be fully functional again. The person is the service centre doesn't know what hey is talking about (I wouldn't trust those people - they just want your money).

Can we connect a normal earphone / headphone (those that we connect to the Desktop PC) to the Android phone or devices? This is because I notice that the one on the left (the original one that come with the phone) have 4 connector but the one we use on Desktop PC have 3 connector. Was wondering if it will short-circuit and damage the phone or the port itself.
|
The typical audio only jack has 3 rings, usually call Tip, Ring, Sleeve ( TRS ). These typically map to Left , Right , and Ground . Phone manufactures wanted to make this jack work with existing headphone so they used a connector with 4 rings, called Tip, Ring, Ring, Sleeve ( TRRS ). These map to Left , Right , and Ground just like the 3 ring, but the final connector maps to a microphone . This makes it so that if you plug an audio only cable into it, the microphone input gets connected to ground so nothing is hurt . It also means that if a headset with microphone is connected to an audio only device, the microphone is connected to ground, also hurting nothing.

Total Available Internal storage on my Sony Ericsson is ~412MB. This is really low but many apps apparently need to be installed there and others still need a footprint even after being shifted to SD card. What's the best way around this if I want to install more apps? It's a shocking bit of design to be honest, unless I'm derping and completely missing out on something easy.
|
There are many "*2SD" methods, and they generally involve root access. My personal favorite is Link2SD. It uses symlinks, which take up (practically) no space. The actual program, data, libraries, etc are stored on a second partition on your SD card. This comes with the downside of actually having to create two partitions on your SD card (meaning it will have to be formatted). If you have root, you likely have a custom recovery installed that can automatically partition your SD card. The upside of multiple partitions is that you can mount your sd card when plugged into a computer without causing the apps to disappear from your device. This is because only one partition is actually unmounted from android and mounted on the computer, and the other partition holding your apps is never unmounted.

Everything was working fine for a long time. But suddenly the device is getting slower than usual (e.g. apps react slowly when starting an action -- like the RSS reader takes "ages" to open an article). Also, several apps start crashing: force-closes as well as unexpected restarts. Sometimes this even involves some automatic reboot of the device. Is there anything I can do, besides doing a factory-reset? Preferably it should work on un-rooted devices. Remark: not all described problems may occur together, so on one device e.g. there might be no automatic reboot involved. Question remains the same, nonetheless.
|
A behavour as described above in most cases indicates something's messed up in the system. The most likely candidates here are: Application Cache Dalvik Cache As you might have guessed already, different solutions are available for rooted devices -- but only few for non-rooted devices, which cannot directly access the Dalvik Cache . So read on below examples until you hit something working for you, or continue to the very end for all options. rooted and non-rooted devices: remove obsolete apps Cause of a slow-down might be some app, hogging all resources. Those apps usually can be identified via the "battery consumption" page in Settings. But even if you cannot find it there, it cannot hurt to remove apps you once installed but no longer need (see e.g. stackexchange-url ("Alix' answer")). You can also disable some system apps you don't need (keyword: bloatware ). To do so, go to Settings → Applications , select the "All" tab, and walk the list to find those apps. Tap their entry, and you should find a "disable" button. It might be grayed out: if so, you first have to "force stop" the app, and maybe to "uninstall updates", before the "disable" button becomes accessible. Note however, that this possibility will not exist for all system apps. For rooted devices, there are several tools available allowing you to "freeze" or even remove system apps (be very careful with the latter); one famous example is Titanium Backup. rooted and non-rooted devices: Clear the Application Cache If you're lucky, it's simply that: the Application Cache got filled/messed up. This can be easily resolved, even on non-rooted devices: With methods available by default on each Android system: From your homescreen, go to Settings → Apps → Manage Apps . Make sure to view All Apps , not Downloaded only Walk the list, open each app, and hit the Clear Cache button Easier method using helper apps: There are several apps available on the Playstore which allow to clean all application's caches at once, so you don't have to walk a long list and do it manually. One example for such an app is 1Tap Cleaner, which also can clean up several other histories like e.g. the browser history rooted devices: Clear Application Cache and Dalvik Cache Even more likely for the described case is a messed-up Dalvik Cache -- especially if you tested a lot of apps, permanently installing/uninstalling different ones. So a cleanup of the Dalvik Cache most certainly will solve the situation. As a side effect, it will certainly speed-up things. No negative side-effects are to be expected. Via Custom Recovery This is the most effective way and sure to really do the job. This example is based on the ClockworkMod Recovery , which is most widely spread. It should be equivalent with AmonRa Recovery . Boot into recovery mode (how to do this often depends on the device/ROM used. For CyanogenMod users it's most easy: Long-Press the power button, select "Reboot", select "Recovery") Using the Volume controls, select Wipe Cache and approve it using the power button. On the next screen, approve the action the same way. This way you easily clear the Application Cache as described above, all at once, without the need of an extra app. Go to the Advanced menu, select to Clear Dalvik Cache the same way with the Volume and Power keys and approve it. Go back to the main menu, and select Reboot . The next reboot will take longer as usual, so don't worry: Android needs to rebuild the Dalvik Cache , that's completely normal behaviour. Helper apps: Several apps offer options to cleanup the Dalvik Cache (e.g. SystemCleanup and Titanium Backup PRO Key ★ root). You can try those; but I'm not sure if one of them really "wipes" the Dalvik Cache . At least for Titanium Backup I know it only removes remains from uninstalled apps (i.e. obsolete Dalvik files). rooted and non-rooted devices last resort: Factory Reset If none of the above does solve your problem, there's always the Factory Reset . Basically, this does all the above (wiping Application Cache and Dalvik Cache ) -- but it also wipes the <code> /data </code> partition. This means: All your settings and data (except those stored on your sd card) as well as all apps you installed yourself are gone. So be sure to have a good backup before doing this (see e.g. stackexchange-url ("Full Backup of non-rooted devices") for how to achieve this). rooted devices: fstrim Another reason for slowing things down lies in the storage. A little background for understanding: On the flash memory used in our devices, each cell can only be written so many times. To prevent capacity loss and wear-out, the flash controller applies an algorithm called "wear leveling" to evenly spread writes across the medium. Of course, to prevent data loss you want to write to "empty places" only (except when explicitly overwriting a file). And here comes the culprit: To speed things up, the file system in most cases only marks files deleted, but doesn't tell the controller about the "freed blocks" -- so it becomes inefficient with time. Android 4.3 addresses this issue with appropriate <code> fstrim </code> calls, telling the controller once a day which blocks to consider freed. Some ROMs integrated a comparable feature also in earlier versions of Android, mounting file systems with the <code> discard </code> option (so the controller is informed at once on deletes), but this slows down deletes a little. For devices not having addressed this in either of the two ways, it might be worth to take a look at the Lagfix App, which calls <code> fstrim </code> in a user-friendly way for selected partitions. Running that once on a long-used device may speed up writes by a factor of up to 30, and even reads get a little faster.

I've had my Galaxy S3 for a few months now, and have always been able to connect to my PC via USB. A few days ago, it suddenly stopped working. I've found stackexchange-url ("many") stackexchange-url ("other") stackexchange-url ("Android.SE") stackexchange-url ("threads"), but none have been able to answer my question. Symptoms: when I plug the phone in via USB, the phone beeps, I get a lightning bolt on my battery, but that's it. There are no USB options in the pull-down status bar, and the PC does not recognize that a device has been plugged in. Click screenshot for full size. PC System: Windows 7 x64 with the latest drivers and Kies software from Samsung. Phone info: Samsung SGH-i747 Android version 4.0.4 Baseband version I747UCLG1 Kernel Version 3.0.8-704434-user Build number IMM76D.I747UCALG1 What I've tried: My wife has an identical Galaxy S3--I plugged her S3 into the same cable, and it was recognized immediately. So I know the PC and cable are both working correctly. Uninstalled and reinstalled the drivers several times anyway -- alone AND with the Kies software. Every USB port on the box Factory data reset--both from the setup menu, and the diagnostic bootup menu USB debugging mode, both on and off. Changing the UART and USB settings in the *#7284# PhoneUtil. After my last factory reset, it's set to PDA/MTP+ADB. Anything else I should try? Is there a way to determine if the USB plug on the phone is bad? Edit: screenshot from my wife's phone, using the same computer, same cable:

Update: Try cleanup and reinstall of drivers as mentioned here. Seems to have worked for others. This seems to be a known issue, and many have had success by using a different cable, connecting to a USB 3 port etc, but clearly, those won't work in your case. Not sure what your usual usage is, but for file transfers, you can use Airdroid, which connects through wifi.

Since quite some time I've been getting a file <code> /sdcard/logfile.log </code> which gets really big quickly, last time I checked it was about 2MB. That file seems a general system log since I remember seeing references to several applications, and lines like <code> beginning of /dev/log/system </code> and such. So it looks like some app is redirecting global system logs to SD card, possibly because I have moved almost all applications from internal storage to SD card. So how can I find out which app is doing this, and if that's not the cause, how to find out? Below is the beginning of a sample log, most part of which refers to the On{X} application. Note however that, as I said, I have seen references to several apps, for example initially I remember stuff from Google+, which then was moved back to internal storage without success on preventing the log file to appear. As I said, this seems rather a global log file, and the question is how to find out which app is redirecting it to sd card. <code> --------- beginning of /dev/log/system 12-13 04:20:51.205 E/MobileDataStateTracker( 280): default: Ignoring feature request because could not acquire PhoneService 12-13 04:20:51.205 E/MobileDataStateTracker( 280): default: Could not enable APN type "default" --------- beginning of /dev/log/main 12-13 04:20:55.335 E/wpa_supplicant( 347): Unsupported command: BTCOEXMODE 1 12-13 04:20:56.875 E/CMarlinMediator( 128): Error : MarlinMediator Failed to get TrustedTime 12-13 04:20:57.055 E/CMarlinMediator( 128): Error : MarlinMediator Failed to get TrustedTime 12-13 04:20:57.125 E/CMarlinMediator( 128): Error : MarlinMediator Failed to get TrustedTime 12-13 04:20:57.215 E/CMarlinMediator( 128): Error : MarlinMediator Failed to get TrustedTime 12-13 04:20:57.325 E/CMarlinMediator( 128): Error : MarlinMediator Failed to get TrustedTime 12-13 04:20:57.335 E/wpa_supplicant( 347): Unsupported command: BTCOEXMODE 2 12-13 04:20:57.915 E/socialphonebook( 674): SettingsParser: key not found. key=[account-types] 12-13 04:20:59.905 E/ResourceLoader( 563): Error loading resource ... </code>

Recently I switched my custom ROM installed on my HTC Desire to a 4.1.2 based ROM (PARANOIDANDROID based). The ROM works fine but sometimes the device has serious lag of several seconds. I assume that this may be caused by a SWAP partition I created once on my SD-card but that was never used by my previous ROMs. How can I find out if the SWAP partition is used or not?
|
Simply get yourself a terminal app (a good choice would be Android Terminal Emulator ), start it, and enter the command <code> free </code> . The output then should look like this: <code> total used free shared buffers Mem: 487344 474312 13032 0 42224 -/+ buffers: 432088 55256 Swap: 0 0 0 </code> This example is from my Motorola Milestone 2 , and you can see: it does not use any swap: "total" available swap space is "0". If your device would use swap, at least the numbers for "totals" and one of "used" or "free" should be > 0.

Not sure why, but today the voice on Google Now has changed from a male to a female. I'm in the UK and before I had a male with a British accent but now that's changed to an American female. I can live it, although I would prefer to have the male one back. It sounded more human IMO. Anyone know how I can get it back? I've tried changing the language setting but it didn't make any difference. EDIT: A while ago Google changed the voice to a female with a British accent and AFAIK there's no way to get the male British voice back. Not really a problem for me anymore as the new voice seems to have improved a lot.

Not sure if this question can be answered any more, because I have had the English UK male voice back for a while now. Turns out it was Google changing things - not me. Just one day it reverted back to the male voice. Thanks to the guys who answered though! :)

My wife got a new phone with a new service, so I get to have her old phone to play around with. Since the old phone no longer has cell phone service, I want to completely disable the cell phone or radio portion of the phone so that it doesn't eat up battery. This is a CDMA phone, so there's no SIM card I can just take out. Enabling Airplane mode works just fine, except that also turns of WIFI, which I have to manually turn on. And if I reboot, the phone stays in Airplane mode, but it turns WIFI back off. Is there a way to modify the phone to turn off the cell portion completely and permanently, at least to be able to withstand a reboot (not necessarily a factory reset)?
|
You could use some automation app to do this, having two steps in its task: Switch to airplane mode, and then enable WiFi. Tasker is one app that can handle this, but I'm pretty sure some of the free profile-switchers are also capable of this. With Tasker you could place this with a profile executing as soon as Tasker is started -- other apps might provide "default/base profiles" for this (like Locale does), or you might have to add it to each profile you create to make sure it always works. Depending on your device, you could also use Dazzle Configurable Switcher (which comes free). As the name suggests, it offers a bar with "toggle switches" which you can configure freely. One of the toggles is for the (cell) Radio. But not all devices support this: it worked fine on my HTC Wildfire , but my Motorola Milestone 2 won't let me switch that separately. Here the state should be remembered even after reboot -- but again that might depend on the device.

Is there a way to check if an APK file hosts native code? There are many reverse engineering tools (e.g. apktool , androguard ) from which you can reproduce the source files of an Android app but I'm not sure if there is a de facto solution which you can use to assure that an APK contains native code. Maybe someone can search for ARM binary files in the source files of an app. But how to know which directories to check? Is there a more standard way to do this?
|
I think stackexchange-url ("this StackOverflow answer") should point you in the right direction: All of the native code for an app is stored in the libs/ directory in the root of the apk. It's compiled ARM or x86 code, or both. You can find it in libs/architecture_type/lib_name.so. You can dissemble the code with objdump or gdb. Decompiling is a much harder task, but you can find some software that might work for you.

I accidentally let the battery on my Nexus 7 run completely empty, and now it won't start up anymore even after charging overnight. How can I make it work again? This is what happened in detail: My battery ran low, and I had no time to recharge it. I forgot about it, and found my tablet powered off. I attached it to a charger (the official wall-plug adaptor), waited a few minutes, and then turned it on. I expected it to be able to run from the cable like my phone, but it reported 0% battery and shut itself down immediately. I retried it after a slightly longer time. This time I didn't get to the home screen, but was shown a black and white animated battery icon. I pressed the power button, and the animation froze, and only disappeard after a long time (I put it away and discovered it was gone after a few hours). Since then I've been loading it for > 12 hours, but I haven't been able to get any response. The charger gets warm, but the tablet doesn't. I've heard that once the battery is competely discharged, it only charges in "trickle mode" (that is normally used to top off a 98% loaded battery safely), and can take a very long time to become operative again. This would explain why the adapter gets warm but not the tablet. If this is true, is there any way to speed up charging?
|
Try pressing the power button for > 30 seconds. If it does not work, try to alternate power sources (PC/laptop USB port, and AC adapter) while repeating step #1. Still no go? You may have to remove back cover and reconnect battery. Warranty case. ( source )

I've got a Galaxy S3, and I love it, but it drives me crazy at night sometimes. GMail will get a new message and it'll ring. The LED sometimes flashes all night long, etc. I've seen a couple of apps that purport to solve these problems, but they've got some bad reviews. Can anyone recommend a good way to solve my problem? Thanks!

People might expect me to recomment Tasker including a profile -- so I will do this first. But I will include another, free solution as well this time. First, how to solve this with Tasker? Quite easy: Condition: Time (10pm to 7 am, for example) Task: Airplane On (optionally, so no incoming calls) WiFi On (so weather-updates and streaming music for my alarm clock still make it) Silent Mode On (that's the important one: everything off except for media volume) This is just an example of what can be done. Many more options are available, but Tasker costs you about 5 Euro (it's really worth it, as other answers here tell you as well -- you can let hell freeze with it!). If that's too much for you, you have two options: First check with the free 7 day trial from the Tasker homepage -- or look for an alternative. Well, to be honest: nothing can get near Tasker , but for your case there are some options left: Timeriffic is a very good scheduler (can deal well with time based events, like the above described) Llama - Location Profiles can do with location based, time based (don't be fooled by the name of the app), and more I know I repeat myself: Tasker can do all this and much, much more. And if you feel there's something missing: there are so many addons available (all Locale addons fit). And so many apps interface with it...

In /dev/socket directory, if runs "ls -al" in adb, there is no file size information. I would like to know why there is no such information, in the condition that in other directories can show file size information? Thanks.

Sockets and pipes represent Unix' way of inter process communication, and a communication channel has no point in having a size. Sockets are thus not seekable as in go to position x in the file . Linux (which Android makes use of) has 7 file types: Regular Files Directories Character Device Files Block Device Files Local Domain Sockets Named Pipes Symbolic Links See more here

When I started with a fresh SD card, there were only very few folders in it. As time passed by when I tried many apps, I could see the folder list in my SD card seems to grow. It is understandable that while an app is being uninstalled, it leaves behind its folder where it would have kept few files, which may be the settings file or game scores etc. Is there any way I can remove all those orphaned folders in a batch or short operations? I have seen the question "stackexchange-url ("How do one know which folder is created by which android apps")" and can manually do it, but I am interested in kind of automatic solution. My phone info: LG Optimus One (P500) running stock 2.3.3 V20D (rooted).
|
Unfortunately, as the comments state, there is currently no way to automate this - and I for one wish there was, as I find myself deleting loads of folders as well. You should do it manually - but methodically, and it starts to seem to take a lot less time, as you start to think about it. One thing to look out for is folders for game apps that you installed, as they may contain the downloaded game data - which can be quite large, which you may wish to keep incase you want to install and play the game again. Like Izzy mentioned, SD Maid finds some of the orphan files for you - but not all.

I've been taking pictures with a Nexus 4 for a few days now, and noticed that the colors are off on many pictures. Finally today, I decided to do a Nexus 4 vs. iPhone comparison, with the same scenes, and it seems to me that: The auto white balance on the Nexus 4 / Android 4.2 isn't always working; in particular, with incandescent lights, in Auto mode, at times whites are greenish. Forcing the incandescent light mode fixes this. In all cases (incandescent or fluorescent, Auto mode or correct mode specified), the image lacks contrasts: whites are grayish and dark areas lack details. Just walking around with a Nexus 4 and an iPhone while pointing are things around makes this very clear. Is there a way to improve this, or should I just resign myself to the iPhone camera (lens, sensor, DSP, software?) being overall better than the of the Nexus 4? (And my apologies if this sounds a bit provocative, as I seriously hope this is not the case!)
|
This isn't a miracle solution, but: When taking pictures indoor, keep in mind that Android's auto white-balance might make the wrong choice. Look at the image on the screen, and if it feels unnatural, try manually selecting the incandescent or fluorescent settings. Be aware that, at least currently, the Nexus 4 camera doesn't compare favorably to the iPhone 5 camera: on the Nexus 4, pictures tend to lack details, colors are washed out, and images lack contrast with both white and black leaning towards the grey. If you own a Nexus 4 and find this disappointing, let me try to reassure you: first, it isn't as bad as it sounds; second, there is still a chance this can be improved with software; third, don't forget your unlocked Nexus 4 costs almost half the price of an unlocked iPhone 5. Below are some pictures of the same scene I took with an iPhone 5 and Nexus 4, so we can compare them side-by-side. This first shot was done indoor, in a low light, without a flash. Left: iPhone 5 ( original ), right: Nexus 4 ( original ). This second shot was done outdoor. Top: iPhone 5 ( original ), bottom: Nexus 4 ( original ).

I am coming from the iPhone, and there was using an app called Camera+ , which worked well for my workflow. On Android, I am now looking for a way to: On the go, take pictures , and store them somewhere. (I don't care where they are stored, they could very well be in a private store specific to the app.) Allow me to go through the picture I took, delete the one I don't like, and for the others, enter a description , and upload them to a combination of Flickr, Facebook, and Twitter. I want to just enter the description once , click on checkboxes for Flickr, Facebook, and Twitter to select where the picture will go. I could do this with the standard Camera/Gallery, with the Flickr and Facebook apps installed, but it requires way to many steps. I'm looking for something simple, that allows for a fast workflow, not for an editing workhouse. Is there any solution out there that would allow me to do this?
|
This solution doesn't require any app: Upload pictures by email to Flickr. As a one-time setup, find your private Flickr email address and I recommend you add it as a contact in Gmail. Then, from the Gallery, share by email, and send it to your Flickr email, optionally typing a description in the email subject. Setup an IFTTT rule to upload to Facebook pictures you send to Flickr. To make it simpler, you can reuse this recipe . Benefits: You're not relying on any third-party app, and can use the standard Android tools. You can queue images for upload (sorting, entering descriptions, deleting locally), even if you are offline, say abroad with no WiFi or data connectivity. The pictures will be queued in your email outbox and will be sent when you're back on the grid.

Yesterday I installed Swype Keyboard to replace SlideIT. At first Swype was working but today it only lets me press the keys and not drag my finger. I think I briefly saw a message saying "dragging is not allowed in this mode" but it went away fast. I've tried disabling and enabling and selecting Swype again but not good. How can I fix this?
|
This happens when you use Link2SD or Apps2SD and move either the Swype App or the Swype installer App to your SD card. To fix it, move the installer and Swype back to the phone and reboot. I found some of this information on http://forum.xda-developers.com/showthread.php?t=1042241 the rest I figured out by trying things.

I've got a Nexus 4 on OS version 4.2.1 that suddenly started to drain it's battery very quickly. When looking in the battery usage I see "Mediaserver"eating 60% of the battery over time, with several minutes of CPU time logged and several hours of Keep Awake time. Typically the screen, phone idle or other services eat up the majority of battery life. I tried closing all apps and charging it up, and sure enough overnight it still drained significant battery, again Mediaserver was the culprit as reported in the Battery usage chart; it had kept the device awake all night and drained 10% of my battery despite zero use. I haven't added a large number of files and I'm not playing music/etc so Mediaserver shouldn't be doing very much on the drive. How can I stop Mediaserver from eating my battery life like this?
|
Killing all running apps didn't solve the problem, nor did disabling the automatic sync for Google account items like videos/photos (which I heard suggested for a similar battery issue). What did work was simply rebooting the device by holding the power button and picking shut down. After rebooting Mediaserver no longer appears to use much of my battery in the usage chart and my charge lasts like it always did. So if you get the same issue, just reboot.

The system bar (aka notification bar) on my new tablet (ASUS Transformer Pad) is always visible, even when watching YouTube "full-screen". The amount of space wasted is not insignificant, especially when watching a 4:3 video. Is there any way to reclaim it and watch videos/play games in real full-screen?
|
It is not intended to hide the system bar (combined soft button/notification bar) on tablets. Imagine the bar is hidden and the app you are currently using does not offer an option to exit. -> Your are stuck within this app. Some custom ROMs offer the option to hide the bar. General option would be to use some third-party-apps like Hide Bottom Bar or full!screen which can disable the bar somehow. Unfortunately these apps require root.

I've just bought a device commercially known as "Zelig Pad", which reports to be "XZPAD700" in settings screen. The device looks made by Hamlet but distributed with Exagerate brand. It carries Android 4.0.4. Anybody knows how to root that device? For sake of curiosity: the device goes in download mode by pressing VOL- + Power. Seeking for something to download into its ROM without bricking it.
|
Believe it or not, the device is already rooted, and it's not documented anywhere. I don't think that starting it in recovery mode for an odd number of times activates/deactivates root, so I just believe the system carries <code> su </code> on its own. If my unit of measure of "rooting" is ad-freeness then I simply tried to run AdFree from the device. No superuser warning appeared but AdFree not even didn't complain about absence of root, but updated the hosts file!! And the device was completely ad-free. I also tried to install ES File Manager, and found this magic file: <code> /system/xbin/su </code>

At the very bottom of my device (MT6577 + ICS + TouchWiz Launcher) are the default icons for "phone", "contacts", "web", and "applications". I want to replace them with my own apps in my custom ROM so that the custom apps appear by default on the dock. Now, the problem is for instance, I removed stock "phone" and "Contacts" apps from <code> /system/app </code> and copied new phone and contacts app in there. Then I created the build, flashed the ROM and rebooted. After reboot, the places for phone icon and contacts icon were empty. It's like: Before replacing the dock was - <code> phone - contacts - web - App </code> After replacing the doc is - <code> empty - empty - web - App </code> Is there any specific file I need to edit to do the trick ? Any help/suggestion would be immensely appreciated! Thanks.
|
You'll need to edit the apk for the default launcher, which in this case is TouchWiz launcher. You'll need to figure out how TouchWiz gets its default setting, my guess is it would be in some of the xml files in the /res/values/ folder for the launcher, which should make modding easier as you'll only need to extract the apk, edit the files you need, and recompress and probably resign the package but it may also be hardcoded into the code in which case you'll need to decompile, reverse engineer, and recompile the Dalvik class files in addition to the previous steps. These are some tools that might help you do these modifications: apktool: A tool for reverse engineering Android apk files smali/baksmali: An assembler/disassembler for Android's dex format jarsigner: tool to sign an apk (included in SDK)

For those people who are interested in flashing custom roms after rooting their android device: Does a website exist that provides a definitive, quick & up to date guide to the numerous and varied custom roms that are available for the android platform (obviously not the whole kaboosh, but something that gave a flavour). Generally I hear about CyanogenMod, MIUI & occasionally AOKP (if i'm not mistaken). Fair enough if you have the time in the day to watch various youtube channels and do searches on the countless android orientated websites, i'm sure most people don't. (I have seen similar questions asked here, generally people have named a few or just said see XDA)
|
There is no such site that lists all the available ROM's for all the devices - if there was, it would be huge. The best way to find a custom ROM, as well as ways to flash & guides, is to check the more popular forums - such as XDA-Developers or the Android Forums .

I thought that ICS, which is the underlying OS version for a Kindle Fire HD, supported a standard way of taking screenshots by holding down power button + volume down key. This does not work for me. Can someone confirm whether this is indeed the case or whether I'm just being slow in not holding down the buttons at the same time?

Similar to stackexchange-url ("Why does HTC Incredible S turn Wi-Fi on by itself?"), it seems my Samsung Galaxy Victory will turn on Wi-Fi at random times. It establishes a connection if certain networks are in range (i.e. any open Wi-Fi). I notice a Wi-Fi setting which allows this phone to keep its Wi-Fi on during sleep, but this is currently disabled. Is there a way to prevent the device from looking for Wi-Fi networks? If this is specific to Samsung devices, has anyone figured out how to take care of this issue?
|
After some searching, it turns out this feature is provided by the Sprint network (although that doesn't rule out that other carriers/devices may provide similar functionality). The Q&A at community.sprint.com points to the Sprint Connection Optimizer, AKA the "Intelligent Mobile Network and Wi-Fi Setting." This setting "will automatically connect you to Wi-Fi networks on your device's remembered list." This setting can be enabled/disabled by navigating to Settings > More settings > Mobile Networks > Sprint Connections Optimizer.

I have one "generic" Android tablet, and often when I come to install and app, Google Play says it's incompatible with my device. It happens even on popular apps such as Twitter, Instagram, Evernote, Foursquare and even Google Maps! I know it works, because if I copy the APK from my Motorola phone onto this tablet and install it manually, it runs fine (at least Instagram and Twitter do). I'm not trying to make Instagram work on my tablet. I'm trying to find a way to install the apps from the Play Store. How and where does Google Play performs a compatibility check on my device? I suspect said check is failing somehow. I want to be able to install apps that will work on my device and stop Google Play preventing me.
|
When developers make apps, they have to specify any hardware/software requirements in a file called the <code> androidmanifest.xml </code> file. These can be hardware or software requirements, such as if the app needs GPS, or telephony features - or if it will only work on a certain Android version. When you use Google Play, it sends your device's 'features' to the server, and then filters apps accordingly. The most likely reason it is deemed incompatible by Google Play is that it is set to require a certain screen resolution - or maybe portrait/landscape mode defaults. Some tablets have a low resolution, and also tell google play that they cannot go into portrait mode. It could also be, your tablet being generic, that it does not have the required GPS or sensors that the manifiest file says it needs, and the market is stopping you from installing because of that. I shall find out what the instagram app needs (look at it manifest), and edit this answer for you. EDIT: According to the Instagram manifest, the only 'required' item is the glEs version - minimum 131072. It could also be because of your tablets country/carrier setting. Twitter needs a minimum of Android 2.1, and may also need a Vibrator, as it uses the vibrate permission.

So my Galaxy Nexus has been fine until now. It has been running Android 4.2 and it was going perfect, then like a day ago I go to plug it in and it just won't connect via USB. It charges on USB but that's it. The drivers are installed and the problem is not my computer; I tried it on another computer as well, I haven't changed anything at all. The last option I think for me is to do a factory reset, which I reaaally don't want to do. It won't even come up with USB connected on the phone. Any ideas? UPDATE I sent mine back for repairs and the mobo was screwed on it. No idea what caused it.

Replace the USB port. You can find them (port and ribbon) on eBay for $13, including shipping. There are 6 screws to open the phone up. Separate the outside case; there is 1 screw at the bottom once you open it. Take out the large black piece (I think its the mic and vibrating mechanism). Undo the bottom portion of the antenna. Undo some of the connectors on the the main board to be able to lift the bottom up some and gain access to the USB ribbon. Remove and replace with new ribbon. Be careful when lifting the main board and removing the USB ribbon to make sure nothing is connected so you don't rip or break anything. Plug all connectors and antenna back in. Put the battery in to make sure it turns on and you have reception. If you're good, turn it back off and screw everything back together. Make sure you get a little kit off eBay with the tiny screw drivers and the plastics tool to pull apart the case housing.

Basically your options are to find a ROM to flash for that device and flash it. Or find the apk that you removed and re-add it. You will probably need either a custom recovery, like ClockworkMod, or you may be able to put the apk back on the device using ADB from the android SDK. I am not sure what the Custom ROM state is for this device, so it may be easier to find the apk that you need. If you can't find the apk, but can find a custom ROM, you could pull the apk from the ROM package.

I noticed that certain Samsung batteries say "Near Field Communication" on them. Is the NFC h/w located in the battery? Does it differ by the manufacturer of the Android device? A friend of mine claims (for Samsung devices) that only the antenna is located in the battery, and the rest of the NFC tag is located inside the phone, but has no evidence to back up his claim.
|
In this specific case your friend is correct, but it can probably vary somewhat. We'll take the Galaxy Nexus as an example since it's a reasonably accurate internal representation of the other Samsung devices. The iFixit teardown helpfully identifies all of the major components of the device and their function. In step 5 they remove the wrapping from the battery to expose the NFC antenna underneath. Later, in step 12, they identify the NFC controller on the main motherboard. Putting the controller itself on the battery is perhaps possible , but I'd imagine it is not really realistically feasible. For one, it would probably increase the fabrication costs of the batteries an unacceptable amount (the antenna, conversely, is likely not very pricey). It would also require the battery to have some non-standard and comparatively complex circuitry to transmit data from the controller to the motherboard, whereas the antenna is basically served by a simple conductive contact to pass the signal along. This is mostly conjecture, though - I'm not an electrical/hardware engineer (I don't even play one on TV).

I wanted to uninstall and move some applications from my homescreen, but when I tap and hold to get the menu for uninstalling and editing, nothing happens. The icon is selected, but there is no response. This was working fine earlier, but has been broken for the last month or so. Does anybody know if this is connected to any settings, or would you guess it's an error?
|
As it turned out, my "raw guess" was a direct hit -- so to make it easier to find for future "searchers", I make it an answer as promised: This problem is mostly caused by the fact that something got messed up with the apps' cache and/or data. So what you should try first is: Go to Settings → Apps → Manage Apps Select your launcher Hit the button labeled "Clear Cache" If that doesn't solve the issue, take the same steps -- but in the last step hit the "Clear Data" button (note: This will reset the launcher configuration as if you just removed the app and did a fresh re-install). If you still had no luck, you could simply uninstall and re-install the launcher (as long as it's not a system app). This will do all the above, but additionally remove (and on re-install re-create) the apps Dalvik cache. Count it as "partial factory reset". Having mentioned the dangerous word: A factory-reset can serve as a "last resort" (as it cleans the entire device) -- but you would lose all your data that way, and needed to re-configure everything anew. In case you have to do that (I don't think it is necessary for your case here), take care to have a backup of as much of your data as possible.

I wasn't satisfied with the selection of sounds the phone was giving me for the alarm, so I installed ES File Explorer and picked out some ringtone sounds from the phone's <code> system/media/audio </code> folder. Ever since, those sounds have been showing up in the Music Player playlist. How do I stop them from doing so? I'm using the default music player on a Sony Ericsson Xperia X10 Mini Pro running Android 2.1.
|
As my suggestion in above comment seems to be relevant, I hereby convert it to an answer as promised: It might be that's some "cached info" somewhere. You could try walking your apps ( Settings → Apps → Manage Apps ) for all fitting things (media player, media scanner, es file explorer...) and delete their caches. Check whether that solves the issue. If not, you could try to delete data for media player/scanner at the same place (at least scanner data should be rebuilt on the next scan; the player would lose its configured preferences when deleting data). Keep in mind to check all apps (not just the downloaded section: the latter only applies to the apps you've installed yourself, while the former also includes system apps). When you've cleared cache and data, you library might appear empty at first. This is no bug or problem -- it's just the Media Scanner needs to rebuild its library. This happens on certain events: after a reboot after a re-mount of the sd card (e.g. plugging it into your computer via USB, then disconnect it again) when another app triggers it (take e.g. a look at SDrescan for this).

As per the title, what hardware do I need to be able to run various versions of Android?
|
Start with the Android compatibility page . This outlines goals for Android's compatibility and links to the current Compatibility Definition Document which has the technical requirements. All versions of the CDD to date are below. Android 4.3 , Android 4.2 and Android 4.1 "Jelly Bean" Android 4.0 "Ice Cream Sandwich" Android 3.0 "Honeycomb" not available (since it was not a public open-source release) Android 2.3 "Gingerbread" Android 2.2 "Froyo" Android 2.1 "Eclair" Android 1.6 "Donut" These are also linked to from the Android Compatibility Downloads page which also includes test suites. There is no Compatibility Program for older versions of Android, such as Android 1.5 (known in development as Cupcake). New devices intended to be Android compatible must ship with Android 1.6 or later. Notable points: The absolute minimum requirements for Android were originally stackexchange-url ("a 200 MHz processor, 32 MB of RAM, and 32 MB of storage"). Out of the box, stackexchange-url ("Android is incompatible with ARMv4 or lower"); ARMv5 or higher is needed to run native code without modifications. Android 4+ requires an ARMv7 processor. Custom versions of Android 4+ have been made for ARMv6 however. The requirements in these documents must be met for a device to be "Google Approved" and ship with the official Google apps such as the Play Store and Google Talk. However, they are not necessarily hard requirements. Since Android is open-source it can be modified to run on lesser hardware, and the opposite is possible as well — modifications necessary to run the OS on a device may make the firmware image too large to fit on it, just for example.

I have a friend who shall be moving to Switzerland during the early part of 2013. He wishes to know is their a Swiss Google Play Store, or do Swiss residents use the German Play Store? If this is the case what happens (if anything) to his UK account and is the transition relatively straightforward. If this is not the case and a Swiss Google Play Store does not exist, neither do Swiss residents use the German Play Store - is their a way around it. Would he still be able to access the UK Google Play Store ? In order to do so doesn't he have to still be a resident (can he use someone elses address ?) In order to access it, is all that is required is to maintain a British Bank Account ? Is it simply a case of you can access any Play Store from where ever you are residing in the world ? What happens therefore if he wishes to order a Nexus device from the UK store in terms of postage costs and import duty ? If he is able to register at the German Play Store would this be a more viable option as surely postage and import duty would be less than that from the UK ? He has heard that even though Google has a HQ in Zurich, most Swiss are heavily iOS orientated.(He is reluctant to follow that path if it can be helped) Perhaps a Swiss person can give some clarification or advice regarding the above matter for him (or what do the people who work for Google in Zurich do & what did the employees who came from countries such as Germany, USA & UK do with their accounts ?) Thankyou for your understanding regarding this matter

He will still have access to all his purchases. He will NOT be able to access the UK Google Play Store, unless he uses alternative methods (VPN/Tunneling/Market enablers..). Assuming he managed to access the UK Play Store (2), he will be able to purchase as normal provided that he has access to his UK credit/debit card. In order to purchase a Nexus device, he has to use his UK credit/debit card, and select a UK address for shipping, and then have someone forward him the package. Provided that the devices he purchased was activated in the UK, he should still the Books and Movies apps on his Android phones/tablets. Some devices however will automatically freeze these apps on boot if the device was not activated in a supported country. NOTE: Devices , Books , Magazines , Music and Movies and TV are NOT available in Switzerland without using methods that bypass the restrictions. NOTE: The answer above is based on my experience with dealing with Google purchases, market restrictions, and international shipping. I have never dealt with the Swiss Google market specifically, but the experience should be the same.

I guess most of you at least have heard about WakeLocks. Many of you will have experienced them already -- wether knowingly or not. Some may know how to deal with them in general -- but only few know how to deal with the "more complicated candidates". For those who don't know, though above link leads to an explanation, a short summary: Apps may request a <code> WAKE_LOCK </code> to keep a device component from "sleeping", so they can perform a task even when the display is turned off. This is very useful in most cases (e.g. keeping the screen on while navigating, keeping WiFi active to stream music) -- but used in the wrong way, it causes your battery to be drained within short term (up to 25% per hour). Most times it is easy to identify the source (usually a bad behaving app) -- I will show this in an answer below, as it might prove helpful to many users. But what to do if the app which requested the WakeLock exits without releasing it? The Android system stackexchange-url ("will not take care of it"). Sure, a reboot would solve the issue -- but it is not always an (desired) option. So, from a users perspective (I'm not asking about development solutions, but how a user can handle things): What can be done _ by the user _ to solve the issue and avoid further battery drain? I prefer answers not involving root (so all users can benefit from it). However, "rooted solutions" are fully valid and welcome as well.
|
How can I tell I'm affected? This is probably the first question to those not familiar with this topic. With Gingerbread (Android 2.3) and above, you've got a service aboard helping you to figure out: battery statistics. Though manufacturers tend to place it at different points, it's mostly found in Settings → About the phone → Battery or similar, and shows a list of the apps having used most of your battery. On top of that is a small graph. Tap that, and it brings you to a screen similar to this one: Screenshot of battery statistics on Android 2.3 I chose a screenshot from one of my devices which illustrates the issue. Looking at the lower two blue bars ("Aktiv" = Device was kept awake (active), "Bildschirm an" = "Screen on"), the right-most blue bar on "Aktiv" indicates a WakeLock: Device was kept busy despite the fact the screen was turned off. So by this we can be pretty sure we've got a WakeLock -- but we cannot tell who caused it. If your device does not offer this screen (or the bars at the bottom: I just discovered e.g. the LG Optimus 4X running Android 4.0.3 has cut these bars off), you can find them e.g. using GSam Battery Monitor: Similar information from GSam Battery Monitor -- here the mentioned "blue bars" are yellow/orange What caused the WakeLock? Unfortunately, this question cannot be answered using pre-installed apps (except for, maybe, some Custom ROMs). But there are tools available that can. The best known candidate for this is BetterBatteryStats, and shows us the cause in its partial wakelocks section: Screenshots from BetterBatteryStats In the first example 2 (taken from the app's playstore page), the event causing most of the WakeLocks was a desired one: We don't want the playback stopped while listening to music. So the second example 3 (taken from a real case on one of my devices) might prove better: the topmost 3 events are caused by the very same app, which needed the WakeLock to keep the IMAP push service active. For an alternative to BetterBatteryStats , check out the Wakelock Detector app mentioned in stackexchange-url ("UzumApps' answer") -- which seems easier to handle especially for non-techies: Wakelock Detector -- Click image to enlarge. (Source: Google Play) What can be done? If the case is as clear as in the second example in the previous section, the action is quite obvious -- at least in my case: I don't need to be informed immediately when a mail arrives; a delay of 30min is absolutely acceptable. So I went into the mail app, disabled IMAP Push (see also: Push Email), and instead switched to a 30min poll interval. WakeLocks did not entirely disappear, but dropped markably -- battery life improved noticably. Then there's the case mentioned in the question itself: A bad behaving app not releasing its WakeLock. Confront the dev with your findings and ask for a fix. If he delivers: problem solved. If not: There's almost always an alternative app available. What if it is the Android System itself? Yeah, sometimes it looks like just that: 98% or more consumed by some Android service. Oh, if it's 98%, in most cases the candidate is named LocationManagerService . Bad guy spying at us? Not necessarily. In this special case, the listed "bad guy" is not even guilty -- at least not directly. Here it is another app requesting the current location too frequently. There's an excellent article on Setera.org about this: Pinpointing Android LocationManagerService battery drain. To give an abstract: It uses Android's <code> dumpsys </code> feature (requires root!) to dump a system state, and lets you investigate the listeners established for the LocationManagerService. A closer look at their configuration shows which are constantly "hammering" it for location info (some do so permanently, i.e. without a break). As the app's ID is listed along, and at another place in the dump even together with the apps technical name, you can still identify it and take appropriate actions. And what about UFOs? Unfortunately, there are such: Apps which registered a WakeLock -- and then exited without releasing it. What's left are Unused F **ing Obsoletes* -- WakeLocks held for no use. So no way to simply bring the app to foreground and re-configure, or making it release its WakeLocks. Here the only solution known to me is a reboot -- and I would like to have a better solution. Of course, if you know the guilty app, the steps concerning it are the same as above: inform the dev, get a fix -- or replace the app. But about getting rid of the current WakeLock? Maybe somebody else can provide a better alternative to the reboot? Are there some recommended further readings? Sure. One for now, I may add more later: [GUIDE] Wakelocks Definition and how to prevent them (XDA Developers, March 2013)

I have an HTC Sensation, about two years old. It's running Gingerbread, rooted but not modded or custom-rommed. All of a sudden, the native camera app started crashing - i.e. it opens and immediately closes. I don't know if the hardware camera is damaged, or if it's just the app. There have been no changes to my phone since it last worked - no new apps, no settings changes, nothing. Any ideas? Are there any other camera apps out there that I could download to replace the native one?

My Nexus 7 had been performing without any issues, however, I locked the screen by pressing the power button as usual and then tried to turn it on several hours later but it was unresponsive. How can I fix this?

I've managed to deal with this problem by performing a "soft reset". Hold down the power button for around 30 seconds, the device should start a soft reset ( i.e. you don't lose any data/settings etc. ) and reboot. -- Why it blocked and prevented me from performing a screen unlock remains to be explained.

I was sure in the version prior to 18.0 you could fiddle around and long press on the URL in the address bar and get a menu to copy the current URL. I just updated Chrome, now if I long press it I just get the magnifying glass which is incredibly frustrating. How can I copy the current URL to the clipboard in the Chrome browser? Chrome 18.0.1025469 Android 4.0.4 Sony Xperia P
|
Turns out I was doing it wrong (well at least on my my ROM). You need to perform two double-taps. Double tap the URL. The first tap will select all of the URL and the second will deselect it and give you the text cursor and that little text selection tab helper thing. Double tap the URL again to bring up the menu. Or you can just keep quickly tapping until the copy menu appears. I find this whole process to be a bit unusual. Other people are saying that they can long press to copy, so not sure if the above is specific to Sony ROMs.

One of the most useful features introduced in Ice Cream Sandwich is "Quick Responses": the ability to send a default SMS message to the caller. "Can't talk now. Will call you back." etc. However, I'm 100% Google Voice. I only ever give out my GV number, and I don't want to broadcast my actual cell phone number by using a Quick Response. Is there a way to use them with Google Voice?
|
This is apparently not currently possible. I'm not the only person with this desire. There's an open issue at Google ( Issue 23176 ). In one of my searches, I found someone who says they looked into the code for the Phone app, and found that it's calling the Messaging app directly without allowing the Messaging Intent, which is what would prompt me to choose the Messaging app versus Google Voice to send the message. The app suggested by stackexchange-url ("dymutaos") looked somewhat promising, but I am concerned about its security. So, unfortunately, this very useful feature is currently useless to me. I hope they fix it in the not-too-distant future.

I just got a Kindle Fire HD which Im planning to give away as a gift to a friend. But I need to boot it and write a review on my website before giving it. So, how can I make it look like I never switched it on? When we boot the tablet, it'll give us a setup wizard. After resetting, we will get to the setup wizard again. My question is, how to power off the tablet without following the setup and will it show the setup when I power it again?
|
Depending on the setup, you may be able to bypass it. This is the case if it is the default Google setup wizard. If it is not, then there may be no way to bypass it, and you will therefore have to follow it through. When you wipe the device, it will show again on next boot, so why don't you just follow the setup and then wipe it? This way it will be as if it was never booted for the next person to turn it on.

In the last few days my Galaxy S3 has gone from lasting 12-13 hours to about 6 hours. On checking the battery monitor it seems to suggest that the phone is constantly staying awake and that Google Services are to blame. I was recently experiencing real problems with Google Chrome freezing the phone so I have uninstalled and gone back to the native browser but the battery issue persists... Has anyone experienced anything similar....is a factory reset the only solution? (Android version 4.1.1)

After trawling through all manner of options I isolated the root cause of this issue. Within Google Account Sync I had a look at all available settings and the one that seemed to be causing an issue was 'Sync Internet' option which was just constantly running (and appearing to be keeping the phone awake. Switching this off has got back my battery back to normal. I still have no idea why my phone was trying to sync the entire internet :-)

On my Android device, while using Internet, Dolphin, and Firefox (left), I see the same version of http://m.chase.com that my desktop browser (right) sees: On Chrome for Android (left), it's different, being similar to what opens iOS browser (right): I want to understand why/how, and then see if I can get Mobile Firefox to load the blue version. I don't think it's the user agent string - I've tried spoofing it already.
|
Note that both iOS browser (safari) and Chrome (desktop or for Android) are based on WebKit engine . That's why they are so similar in what they render. Firefox browser uses a much different engine: Gecko . As an answer for what you want to do, I think that given the CSS and javascript the mobile site loads is different depending on the rendering engine, currently it is not possible to an end user to achieve that. A better design must be done by web developers who made the website, in order to avoid this kind of awkward situations. If what you need is to open that mobile site with a browser different to Chrome for Android, but that it be rendered the same way as Chrome for Android does, I recommend you to use Opera Mobile or Opera Mini (based on Presto engine), here is a screenshot of how it looks there:

When I take a photo on my HTC One X, the date and time that the picture was taken do not appear appear (printed) on the photo. I can't set the date or time in the settings, either. If I use a third party application, I can set the date/time and see the timestamp on the photo. My old HTC Legend (Gingerbread) had an option to choose whether the timestamp would appear or not. Is it a feature not supported by Android 4.x, or is it just because of HTC One X model? It was not present on Ice Cream Sandwich or since I've upgraded to Jelly Bean.
|
This feature is rather be app-specific. Probably the default photo app on your Legend does this by default, while the one on you One X does not. To achieve the desired results on your new device, you might need to find a 3rd party photo app supporting this feature. Your phone is certainly capable of it, that's not the issue.

There are many sandbox apps such as <code> Permissions Denied </code> (which was mention in one of the stackexchange-url ("post")) that can effectively control the permissions that apps which are installed onto your phone. However, they require the user to root their phone. So, are there sandbox apps that does not require user to root their phones and at the same time, allow user to control what permission to be given to the apps. Would appreciate if the apps can run in Android 2 and above.
|
That would be a contradiction in terms: In order to disable permissions on-the-fly, root permissions are required -- no way around that. For non-root users, there's only a different approach: Take the <code> .apk </code> apart before installing, manipulate the <code> Manifest </code> (remove unwanted permission's requests), re-assemble the <code> .apk </code> , and then install the modified package. Unwanted side-effect: No direct updates, as the signature on the package breaks this way. An app doing this is e.g. apktool , available for Windows, Mac and Linux.

The theory is that you should not need to know. When the developer publishes an app there is a manifest.xml file that describes the required capabilities. These can be both hardware and firmware related. e.g. you need a minimum Android version or you need a specific hardware feature like GPS. Google Play then automatically filters which apps you can see and install based on these requirements. The developer can also impose geographic requirements and potentially carrier requirements as well as disallowing specific devices if they want to. In your case the obvious thing to do is to first check if the developer has a website with any more information. If that's of no help try emailing them the filtering can be tricky and catches developers out. If the developer is at all responsive they should come back to you. It is in their interest to have the app work on as many devices as possible normally, so if there is no good reason for it to be incompatible with your device they should appreciate the opportunity to work out the issue. If there is a valid issue then your question may help prompt them to make the information available on a website or in the description.

I'd like to revert to the previous version and stick with that permanently. Is that possible? I have Beautiful Widgets installed, and had it set to auto-update. It just did, and the 'update' is totally unacceptable. I've got several devices, all rooted and running different versions of Android. Some have auto-updated the APK to the new version, some have not (I just disabled auto-update on those that have not).

Android does not natively back up applications so you can't "undo" an app update. Best thing I'd say you can do is something like this howto. It backs up your apks and their settings. It uses Titanium Backup and requires root, but rooting is not your problem.

After reading this article ( Kaspersky smartphone report ) this got me wondering. Obviously if I install a dodgy app through Play Store or directly from a website, that can be dangerous, however if I install a popular app from the Play Store that has 10 million downloads for example, most likely it will be virus free. So most of the Android hacks I've read about are people giving install permission to dodgy apps, however can my android phone be hacked without me installing an app at all?

There is always the possibility of a vulnerability in some app that could cause your computer/phone to be hacked. Browsers are notorious for having bugs that allow the computer to be infected with a virus simply by viewing a page. In fact, one method to jailbreak an early Apple iOS device was to simply browse to a page that delivered a payload via a bug in pdf (source). Android mitigates this by having apps run in their own sandbox. Thus, an app that is compromised can only (theoretically) compromise its sandbox, which includes any permissions it originally was granted. If compromised, it couldn't send an SMS unless it had that permission originally, nor could it modify other programs' data. But even sandboxing is not foolproof. If your phone is plugged in to a computer, it can be 'hacked'. This is proven by most rooting methods that use a bug to get root. Programmers could just as easily create a virus for computers that detects Android phones and installs a malicious app silently, or even roots them and takes over the phone completely. This talk has some great details on app permissions. It isn't necessarily hacking, but it does show how an app with very few, seemingly innocuous, permissions can actually track and do a lot without you knowing. In the end, your android device is a computer, with all the same inherent flaws that come with it. So like a desktop, if you are careful about where you browse and what you install, you'll likely be fine.

I received the 4.2.x updates on my Nexus 7 and the performance has been awful. I tried the Forever Gone hack and it helped but it's still much worse than 4.1.x. I'm not so excited about doing a factory wipe in order to make my system almost as good as it was a month ago. I've never tried rolling back a stock system before, is it possible to download the official nexus image zip and install it from CWM recovery? Or do I have to do a more involved wiping and flashing process? My system is stock 4.2.1 rooted and unlocked, with custom recovery.
|
Don't use full image at recovery! It contains recovery too (CM can repair itself, but reflash of bootloader is not needed). Use <code> fastboot </code> and flash partitions: <code> system </code> , <code> data </code> You will lose all of your data on the tablet, but it is needed because of the different filesystem structure. Without reflashing <code> data </code> you will get a bootloop.

Can I rollback the stock system by just installing an older image zip?

I am live booting the Asus laptop version of Android-x86 4.0 on my Acer Laptop from my USB Pendrive. Everything is working fine, however I want to install the OS on the USB drive instead of live booting it. The USB drive is 16GB in size. I want to live boot the system and then install on the same drive without using any other drives. If possible, later on, I would want to mount some part of the USB drive as the SD Card. How can I do this?
|
The solution is pretty simple, far more easier than I anticipated: Partition your USB drive/SDCard, into two partitions, using this EaseUS Partition Master , which is what I used. Partition layout needs to be one with 1GB of space with FAT32 filesystem, that is for the installer. Remaining partition of type ext3 (Linux partition). The installer, when live-booting from the USB Drive/SDCard, will show the just-created partition on the USB/SDCard, just select that partition to install on it and its done.

When I start the Spotify Android app from my Samsung Galaxy 1 it seems that the internet connection is not working: What can I do to resolve this?
|
Lucky for you, I am a super user on the Spotify community. First, you need to wipe the data for the Spotify app, and then re login. Once this has done, it may take a few seconds for the app to recognise the Internet connection. If that fails to work, reinstall the app, and login again.

Why does Spotify say that there is no Internet connection available when there is one (Samsung Galaxy S)?

How can I get the Easter Egg hidden in Android Jelly Bean? How could I use that Easter Egg to enable a hidden daydream in Android 4.2? How can I enable the Developer options , hidden by default in Android 4.2?
|
Jelly Bean Easter egg: Go to app drawer and open Settings , go to bottom and tap About phone Repeatedly tap Android Version 3 times: It should open a screen showing your current wallpaper and a red Jelly Bean (This step is optional) Tap the red Jelly Bean once and it will change to a smiling Jelly Bean android head, and the screen will show the text Android <4.x version> JELLY BEAN That screen is the Jelly Bean easter egg. But don't close it: it has to be open to enable the... Android 4.2 hidden daydream: Tap and hold down on the red Jelly Bean for about 1 sec. You'll see an animated screen with lots of colorful Jelly Beans and smiling Jelly Beans, which you can play with, pushing ("flinging") them off the screen. In that moment the hidden feature will be enabled: that animated screen is known as BeanFlinger and from now on it will be available (with black background, though) to be selected as one of the Daydreams . The Daydreams are an Android 4.2 new feature, consisting of screensaver apps that can run when your phone or tablet is docked or charging ( more info about Daydream ). Enable developer options (If you enabled them, but you want to revert this process, see Note 3) Go to app drawer and open Settings Go to bottom and tap About phone Tap repeatedly Build number 7 times. Starting at 3rd tap, you'll see a toast saying <code> You are now X steps away from being a developer. </code> After 7th tap, you should get a toast saying: <code> You are now a developer! </code> (If you keep tapping Build number , the toast will change to: <code> No need, you are already a developer. </code> ) The above steps enable the Developer options screen, disabled by default in 4.2 ( more info ). From now on, you'll see the Developer options in Settings screen. NOTES: Tapping the Android Version in About phone screen 4 times will do the trick too, showing directly the smiling Jelly Bean. In Christmas season, along with the jelly beans, you'll may see a wandering candy cane ! It works in both BeanFlinger easter egg (left image) and BeanFlinger daydream (right image). If you don't need Developer options you can either turn off the switch in that screen (left image) or clear data from Settings app ( <code> Settings > Apps > All > Settings </code> ) if what you want is to completely remove the Developer options entry from Settings screen (right image). All of the above work in Android JellyBean 4.3 and Android KitKat 4.4.x too

Before I had CyanogenMod 9 on my Samsung Galaxy S i9000. Then, suddenly it did not boot anymore and I could not boot into recovery mode neither. So I flashed different kernels with Odin (speedmod, vodoo) to be able to boot into recovery mode - which worked. Within the recovery mode (ClockworkMod Recovery v5) I can not access neither my internal storage nor my external SD card. I just see: unknown volume for path [/cache...] Also tried the vodoo Kernel with ext4 support (as I assumed CM 9 uses ext4). Which steeps are necessary to get the phone working again? I can not access any storage at all... I appreciate your help!
|
You should use Odin or Hiemdall (preferred) to flash a new ROM, and or flash a new partition table. It sounds like the partition's have been erased, and as such should be remade by flashing a new ROM.

Recovery Mode does not find internal nor external storage

I'm looking for a landline phone (not necessarily cordless) which runs on Android and gives me the associated control, customisability, and for a bonus, market access. Does such a thing exist?
|
Apparently Yes. The Archos Smart Home Phone is an Android Phone priced at £130 in the UK: http://www.androidcentral.com/archos-smart-home-phone-now-available-get-android-your-landline Although the reviews on Amazon UK arent very good: http://www.amazon.co.uk/Archos-501809-Smart-Home-Phone/dp/B005H0M8LW Binatone iHome Phone iDect with DECT and Android Technology http://www.amazon.co.uk/Binatone-iHome-Phone-Android-Technology/dp/B004EBV1GI Currently unavailable (maybe its that good)

If you are rooted, you could use an app such as MyBackup Root or Titanum Backup to backup Opera Mini, and then restore it on the new device. It is not possible if you're not rooted.
