I am trying to install a new app that is around 2MB (owncloud client), but it fails with "Insufficient storage space...".
From the above screenshot I can't find a partition (other than the few apps) that couldn't fit around a 2MB app 5 times (for extracting etc.).
What causes the error?
When I installed Cyanogen Mod 7, I 'accidently' clicked 'Wipe Battery Status' even though my battery wasn't fully charged.
Now I have no idea what this exactly does (even more reason I shouldn't have clicked it), but I'm wondering whether the phone has anyway of knowing when or if the battery's full.
So should I calibrate my battery and if so, how would I have to do this?

Will factory resetting my device remove the Android upgrade?
I upgraded my Galaxy 551 from 1.6 to 2.2 Android version some time ago with Samsung Kies, now I want to make a factory reset due to reset all of my settings and give the phone to my mother.
I'm wondering about wich version the factory reset will bring to me. It is the factory version (1.6) or the upgraded version (2.1)?
Answer
Factory Reset doesn't take your device back to factory condition. It just clears all data, settings, etc.
So your phone will not go back to older Android version. It will be on the upgraded Android version (or any ROM that you have installed) with all data cleared!

Sometimes my SD card gets "corrupted" and this leads to many read/write errors. Usually, connecting the SD card to the windows 7 and selecting the "Error Checking" (Right click the drive > Tools > Error Checking) option finds the corruption and fixes it.
Is there any tool or app for checking SD cards for drive errors and fixing the same from within the android itself?
I'd also like to mention that I'm on rooted froyo with busybox installed.
Answer
You can fix this with the help of root and a terminal emulator (e.g. Android Terminal Emulator (or, alternatively, using adb shell). The binary to do the job is called fsck, and usually located in either /system/xbin or /system/bin. Sometimes you need a special variant of it, which might e.g. be called fsck.exfat or the like. So first let's make sure we find the right binary:
cd /system/xbin
ls fsc*
If not found, repeat with /system/bin. I will assume here it was found in the first place, and is simply called fsck (adjust the following correspondingly if that's not the case).
As fsck comes from the "Linux core", we can consult its man page for the syntax. Though there might be some options not working on Android, the most basic ones should. See the linked man page for details (or run a Linux VM and use man fsck in case that page disappears) -- I will stick to the basics here:
First we need to find the device your SD card is bound to. If it's mounted, the mount command will assist us:
mount
That's it, basically: Check the output and see where your SD card sits. Usually this is something using vold, but it's different between devices. Output may include something like /dev/block/vold/179:17 on /mnt/storage/sdcard -- in that case, the first part of my quote is our device. In order to repair the "drive", you need to unmount it first. This can be done via the settings menu, or, as we're just in the terminal, by issuing
umount /dev/block/vold/179:17
Now we can go for the repair job. Basic syntax is:
fsck [options] [-t fstype] [fsoptions]
So we first try the simplest approach and hope fsck figures out everything itself:
fsck -C -r /dev/block/vold/179:17
Which basically means: Show progress (-C), and always ask the user to repair (-r) any errors on /dev/block/vold/179:17. If this does not work out, check with the linked man page for further options.
is there a way to sync an Ubuntu calendar application like Thunderbird Lightning or Evolution with an Android device without using google-calendar?
At the moment I am syncing my Thunderbird-Lightning calendars on different computers via Dropbox, what is much more reliable than google-calendar. Another big advantage over google-calendar is, that I can access my appointments offline as well, since the calendar files are synced onto the harddrive of each computer by Dropbox.
I'd like to access those calendars via my android device as well.
The Dropbox-app for android does not support automatic syncing yet, so it seems like I have to use another service.
Apart from that I guess I need to know an android app, that can access a calendar-file stored in ics-format.
Thanks in advance YSN
I tried AirStream and AirDroid but like Teamviewer both are not successful and satisfactory.

Is there a way to check what storage a third party application is using? i.e which of these it uses?
Answer
If you are rooted, this is quite easy to find out.
First you need to find the app's package name, e.g. com.swype.android.inputmethod for Swype, or com.google.android.apps.maps for Google Maps, for example. You can usually search for the app in Android Market, and the link will contain its package name, e.g. https://market.android.com/details?id=com.google.android.apps.maps would be the link to Google Maps. Usually the package names are descriptive enough that you can simply guess which app they represent just by looking at it.
You can do a few simple ls commands in Terminal Emulator or ADB shell to find out the app's name, and where it's stored. However, you will need to have root access to the device since app and data storage is protected.
Pre-installed apps are generally located in /system/app directory. Use the command ls -l /system/app/ to find how much space a particular system app is taking up:
ls -l /system/app/Browser.*
-rw-r--r-- root root 418098 2011-06-26 01:05 Browser.apk
-rw-r--r-- root root 472760 2011-06-26 01:05 Browser.odex
On most Stock ROMs you will see an .odex file along with a .apk file for each app - those are pre-compiled binaries optimized for your given device. You cannot remove them.
3rd-party apps are installed to /data/app or /data/app-private directories. Command ls -l /data/app/[package_name_here]* should return the amount of space taken up by this app on internal memory. For example, here's the output of looking at Google Maps apk:
# ls -l /data/app/com.google.android.apps.maps*
ls -l /data/app/com.google.android.apps.maps*
-rw-r--r-- system system 6330104 2012-02-04 09:01 com.google.android.apps.maps-2.apk
The app data and settings are located on /data/data/ partition. There you will find a directory for each installed app, e.g. /data/data/com.google.android.apps.maps/ for preferences and settings related to the Google Maps app. Again, ls -l /data/data/com.google.android.apps.maps/* will return a listing of all files with their sizes:
# ls -l /data/data/com.google.android.apps.maps/*
ls -l /data/data/com.google.android.apps.maps/*

Android 2.2 (Froyo) introduced the ability to move apps to SD card (or "external storage" on some devices). This introduces a level of complexity since portions of the app get moved around. For every app that you move to SD Card/media area, the system creates a virtual mount point named /dev/block/dm-X, where "X" is a sequential number. It them moves the app's APK (Android package) file and some preferences there. You can view this by issuing a mount command in shell/terminal emulator. Along with other usual mounts, it should show which apps were moved to SD Card like in an example below:
/dev/block/dm-0 /mnt/asec/com.metago.astro-1 vfat ro,dirsync,nosuid,nodev,relatime,uid=1000,fmask=0222,dmask=0222,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0
/dev/block/dm-1 /mnt/asec/com.a0soft.gphone.aTrackDog-1 vfat ro,dirsync,nosuid,nodev,relatime,uid=1000,fmask=0222,dmask=0222,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0
Here I moved Astro file manager and aTrackDog apps to the SD Card on my phone. Use ls /mnt/asec/ to view the directories created for the moved apps. Issuing command ls -l /mnt/asec/* will list the file sizes within those folders:
# ls -l -a /mnt/asec/*
ls -l -a /mnt/asec/*
-r-xr-xr-x system root 332826 2012-02-07 11:21 pkg.apk
dr-xr-xr-x system root 2012-02-07 11:21 lib
-r-xr-xr-x system root 2363522 2012-02-07 11:18 pkg.apk
dr-xr-xr-x system root 2012-02-07 11:18 lib
The wrapper for the virtual partition gets stored inside a hidden ".android_secure" folder of the SD Card:
# ls -a -l /mnt/sdcard/.android_secure
ls -a -l /mnt/sdcard/.android_secure
----rwxr-x system sdcard_rw 4290560 2012-02-07 11:18 com.metago.astro-1.asec
----rwxr-x system sdcard_rw 2161664 2012-02-07 11:21 com.a0soft.gphone.aTrackDog-1.asec
Once moved the app's APK will no longer be under /data/app/ or /data/app-private/ folders.
Another area of interest is Dalvik Cache - an area that contains cached data for each installed app. Upon first boot-up or new app installation the system generates a .dex file for each app that it uses for quicker start-up. These files are stored on /data/dalvik-cache/ partition. Command ls -l /data/dalvik-cache/*[package_name_here]* will return the space taken up by the app's Dalvik cache. For example, here's how much space is taken up by Google Maps app:
# ls -l /data/dalvik-cache/*com.google.android.apps.maps*
ls -l /data/dalvik-cache/*com.google.android.apps.maps*
-rw-r--r-- system app_189 4406016 2012-02-04 09:01 data@app@com.google.android.apps.maps-2.apk@classes.dex
Next, the /cache partition of the internal memory may be used by apps. The command ls -l /cache/ will show you all files stored there, along with sizes and owner information. For example, on my phone here's the output:
# ls -l /cache/
ls -l /cache/
-rw-r--r-- app_13 app_13 3640954 2012-02-07 09:16 downloadfile-1.apk
drwxrwx--- system cache 2011-12-31 21:03 recovery
drwxrwx--- root root 2011-12-31 21:00 lost+found
Besides the standard directories, there is a file named downloadfile-1.apk that belongs to something named "app_13". I can cross-reference this "app_13" name to the listing of ls -l /data/data/ to see that this file belongs to Android's built-in downloader:
# ls -l /data/data/
ls -l /data/data/
......
drwxr-x--x app_13 app_13 2011-12-31 21:02 com.android.providers.downloads.ui
......
Finally, apps can use the SD Card for their own purposes, and there is really no way to track this, unless the app names its folders something recognizable.
I want to find a way in which I can continuously send the Android camera feed to my PC via USB. The reason for specifying USB, is because of performance requirements, I want it to be as fast as possible, hence preferring USB over Wifi. I need the app to be running in the background (will be a service I believe).
I tried some existing apps, but they do not meet my requirements.
Is there any way I can do this?
Answer
IP Webcam(see revisions) does allow the access on USB but it will not show you the option to access in its help section. All you've to do is activate USB-tethering on your device, start server on the said app,and access the server by entering 192.168.42.129:8080 in a browser on PC.
I tested this app on my device running Android 4.2.1.
I have looked at similar questions but could find an answer.
Device: Samsung google nexus s i9020
OS: Android 4.1.2
The phone mounts when the OS has loaded and when there is an option to enable usb storage.
I am trying to root my phone and boot loader is locked. I need to connect to my computer (Linux Mint) to run a program to unlock the boot loader. for some reason, the phone does not get mounted automatically anymore.

fastboot unlock software waiting for the phone
~/android/nexussrootICS$ ./fastboot-linux oem unlock
< waiting for device >
Can someone suggest how could I mount (manual/automatic)? Thanks
Answer
To my knowledge, in fastboot mode you cannot mount the device to your PC. MTP and fastboot are two different things.
According to the CyanogenMod Wiki on Fastboot, the solution might be simple:
If you see at any point when executing fastboot command, the PC is not configured to use fastboot properly. Most typically, this is because you are not running fastboot with elevated privileges.
Which means: you must run fastboot as root user, e.g. sudo fastboot devices or sudo fastboot-linux oem unlock.
If that does not solve your issue, it might help to take a look at the steps necessary to use the adb command line utility: For adb to detect your device, you need to have setup a corresponding entry in your /etc/udev/rules.d. First run lsusb to check how the device identifies itself to the system. These data you can also take from your above quoted log: idVendor=18d1, idProduct=4e20 is the information we need. Now, the corresponding entry in /etc/udev/rules.d/51-android.rules should look like:
SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="4e20", MODE="0666" GROUP="androiddev", SYMLINK+="android%n"
Save the file, and reload the udev service (service udev reload). Re-connect your device. Now adb (or, in your case, fastboot) should be able to find it. You can check that using the command adb devices (or fastboot devices), which now should list your Nexus S.
Note: If this post is too long to read, please see the summary in the last paragraph.
I own an aging Samsung Galaxy S Relay cellphone. It's running Android 4.1.2 and has a built-in physical keyboard. I don't want to upgrade to newer hardware. They say in the XDA Developers forums that, if I want a built-in physical keyboard, the Galaxy S Relay is still the most powerful option available — even though it uses technology which is more than two years old.
I want to help prevent myself from viewing pornography. (I've already joined a twelve-step program for sex addicts, but I still want a second layer of protection.)
I've installed the Qustodio web filter. This web filter only lets me choose between two web browsers: the Android stock browser, or Google Chrome. But it's easy to get around Qustodio. Oddly enough, all I have to do is to enter my browser's incognito mode. Qustodio claims that, when I enter incognito mode, it can detect what I've done and stop me from surfing the web; but, in practice, I've found that it can't.
In a help center article, Qustodio LLC does admit:
Please note that our incognito blocking feature is still experimental.
Fine. Well, I want to reliably stop myself from entering my browser's incognito mode.
I suppose I could switch to a different browser. I could choose the K9 browser. But their (Firefox-based) browser is poorly rated and hasn't received any security updates in the last two years.
Google Chrome for Android is now open source. I suppose I could modify the Chrome source code to disable incognito browsing. But it would be a hassle to keep the browser up to date.
So I guess I'd like to set the relevant Chrome policy instead. I'd need to set the IncognitoModeAvailability policy to 1 in order to disable incognito browsing.
On recent versions of Android (and definitely on Android 5.0 "Lollipop" and newer), you can use an app such as Google's BasicManagedProfile sample app. This will call the DevicePolicyManager's setApplicationRestrictions method (see documentation or source). This method will eventually call the UserManagerService's writeApplicationRestrictionsLocked method (see source). The latter method will, in turn, write some XML to a "restrictions file" in a place where Google Chrome knows to look.
Because I'm running Android 4.1.2: I doubt that I can run the sample app. And I'm sure I can't call either of the two methods.
I suppose I could upgrade the phone to a newer OS. T-Mobile doesn't offer any updates newer than Android 4.1.2. On the XDA Developers forums, "Magamo" points out that CyanogenMod seems to have withdrawn official support for the device a while ago -- even before any stable Lollipop-based ROMs were released. I could choose and find some other ROM. But I've never installed a third-party ROM before, and would rather not learn how to do so.
Dear users of Android 5.0 or higher:
What actual XML does this "restrictions file" contain? Where does it get saved?
(I suppose I could fire up Lollipop in the official emulator and find out for myself, but it's simpler to just ask here.)
Perhaps I can simply create a "restrictions file" in the correct location on my Android 4.1.2 device.
TL;DR: When you reconfigure a Lollipop device in order to disable Chrome's incognito mode, your action will cause an XML "restrictions file" to be saved to disk. What actual XML is inside the file? Where is the file stored? I want to try manually creating a "restrictions file" on a Jelly Bean device in order to see if it will do what I want.
Answer
The XML file alone will not help you. Chrome doesn't read the contents of that file directly. Instead, it accesses it via Android's UserManager.getApplicationRestrictions. In order for this to work, you actually need to set up a "work profile" on your device. In order to do that, you actually need to run the BasicManagedProfile app you have mentioned; this also requires encrypting the device.
Android 4.1.2 is kind of old. From searching at http://www.androidxref.com/, it looks like it lacks UserManager.getApplicationRestrictions. Luckily, there's another way to disable incognito browsing in Chrome. Try that way instead.
I would like to use the 3G connection on my android with my Ubuntu. Is there any method to do so?

Easy Tether from Mobile Stream should work. It's a way to share your internet connection with another device via USB. Get the Lite version (does not support https, or tethering to gaming consoles) or the Full version.
Supports Windows 7/Vista/XP (32-bit and 64-bit), Mac OS X 10.7/10.6/10.5/10.4, Ubuntu 10.4+ and Fedora 13+
Full version supports the following:

This might not be the right place to ask this question, as it falls under the purview of electronics, however that SE is not about consumer electronics. And this phenomena has only happened with Android devices, at least with the Droid 1 and Droid 3. So Android is where I stuck it. Sorry if that's wrong :(
This has happened with both the MicroUSB-to-USB (with AC adapter attachment) OEM wall charger and MicroUSB-to-AC-only wall charger.
Basically, when my phone is charging, the AC plug is completely quiet, but once my phone hits 100%, sporadically the plug portion of the charging apparatus will begin to make squealing noises. It stops once I unplug the phone and will begin again if I were to re-plug it in immediately.
Here's the thing, two other people I've asked cannot hear it. I promise you I am not going crazy and imagining things -- but I have been known to have very sensitive hearing -- hearing buzzing from old TVs and monitors and so forth.
My question, mostly out of curiosity, why is this happening and how can I get it to stop, as it is rather irritating.
This issue seems unique to my old Droid 1 and Droid 3. My laptop or similar high-power chargable device does not suffer from this issue.
Answer
See this very good answer on Electronics SE for details. Basically it's a side effect of the charger circuitry operation - it's by design, you can't change it. If that disturbs you - either find another charger, or bring this one further from you, don't try to silence it with an enclosure - that may lead to overheating.

How can I get "Always on when USB connected" display feature on Samsung Vibrant running Android Froyo 2.2? I used to love it on 2.1 Eclair but when I upgraded to 2.2 it is gone. Any trick to get it back?

I hadn't used my old HTC Hero for a while, but when I rebooted it I got an error saying:
LauncherPro has expired, please download an updated version.
But wifi was turned off and when I tried to get to the home screen, it kept sending me back into the browser. So how can I get to my settings, so I can turn on wifi to download it?
Or is there another way of updating it without me requiring to go to my settings?
Answer
Found this at: http://orlygoingthirty.blogspot.com/2011/01/how-to-uninstall-expired-launcherpro.html
I finally found a workable solution: download the latest LauncherPro APK (or hopefully any other APK). Connect your phone to your PC and mount the SD card. Copy the new APK to the top-level of the SD card and rename it to something short (like lp.apk).
Unmount the phone, then in the phone browser (which is the only thing LP lets you run), type the following in the URL bar:
file:///sdcard/lp.apk
(notice the three slashes)
This will force-launch the Installer application on the phone. Now on my phone, it was set to disallow non-Android Market apps from installing; since the APK is not off the Android Market, the phone popped up an error and offered to let me change the application setting. Which launches the Settings application.

Here tap Clear cache and for good measure Clear data
Each time when I open the Phone app, I see Favourites tab (first one) as default.
This is completely useless for me, because Google uses its weird logic to tell me which contacts are my so called favourites and this logic produces completely wrong results -- i.e. I see "favourite" contacts which aren't truly my favourite ones.
This tab is also useless, if your contacts have more than one phone number, because instead of showing a list in this case and letting you pick the number, it always calls the default number. This isn't working in my case, because I have a lot of contacts which I contact both privately (i.e. during weekends and evenings; using private phone number) and on business grounds (using company phone number). So using the default phone number and Favourites tab is pointless in my case.
For the above reasons, I am not using Favourites tab at all and I am always forced to switch manually to recent phones / call history tab.
Is there any way to make that tab displayed as default each time I open up the Phone app.
My stack:
I am using the default, system Phone app. No 3rd party solution.
Answer
A possible solution is to automate the process of clicking the Call history tab when the phone app is opening. It is not elegant but may help you.
Using Automatem create the following flow:
When UI element appear, then click Record Interactions. A small widget will appear. Open the Phone app, then click on the call history. Click the check mark on the widget. It will take you back to Automate, and many parameters of the Interact block will be filled for you. Click Done.On your home screen, there will be a shortcut created with the label (title) you inserted in step 4. Clicking it will open the Phone app, then show the call history,
It is not elegant because for a fraction of a second, you will see the Favorites tab before the call history is shown.
I currently use Link2SD since my phone's onboard storage is insufficient for more than a few essential apps. It is very effective but limited to when the phone is on.
While changing ROMs, the dalvik cache is wiped and when the phone restarts you see a progress bar saying Android is optimising applications. So given a reasonable number of applications, the dalvik cache fills up the storage long before link2sd can do anything about it.
So is there a way that mounts a sd card folder as the appropriate cache location before the system gets on with booting and doing its business? I know it might involve creating a symbolic link but I just don't know when things are mounted and in what order.

These two (empty) calendars appear in the list of calendars inside the stock calendar app (at least on HTC Sense setups). I'm not entirely sure what they are but they are both unused and cluttering things up. I know I can hide them but is there anyway to just make them gone? When I select Remove Calendars, they don't show up in the list.
Why would anyone want to sync a calendar to a PC anyway? That's the big advantage to a cloud calendar like Google's...
More Information: I have installed HTC's desktop Sync app (not for syncing, for development related things).
I've rooted my device, put it in recovery mode, and have linked it to PC by adb shell.
How can I view the list of storage devices and partitions?

I created a backup of my Galaxy Nexus with adb backup. The resulting file is named backup.db and it's somehow encrypted.
I wanted to restore the backup, but it stops when it comes to restoring com.android.providers.contacts. I used adb logcat to find out what's going on and found out that com.android.acore crashes during the restore process.
I'd like to gain access to the data in the backup and remove the contacts database to restore everything back to my phone. Are there any other ways restoring the data from the backup?
Answer
The file is not encrypted, unless your specify so when creating the backup. It is however compressed (using deflate). You can find out the exact format by looking at Android source (com/android/server/BackupManagerService.java) code, and, technically, should be able to extract specific data from it. However, IIRC, there are some file integrity checks in place, so it most probably won't work if you just delete a bunch of data from it. Unfortunately the restore command doesn't seem to have an option to restore a particular app/package only or exclude a package.
Is it possible to print from an Android device (specifically an Asus eeePad Transformer) without going via the cloud? The ideal is to do it without going via a PC as well, as I'd rather not have to keep switching a machine on just to print.
My only idea at the moment is something like ePrint or PrinterShare on the eeePad and then print via a print server. Using a PC is one option - do any of the apps work with a Samba print share or something Linux-based? The other alternative is an Edimax print server to make the printer available on the network (either wired or wireless). Will it work? Will any Android apps be able to print like that? Are there any better ways to do it with a USB laser printer?
Thanks.
Answer
There's a paid app called ePrint, which I believe works locally to printers attached to a wireless network (printers themselves don't need to be wireless) and doesn't appear to use a cloud service or need a PC in most cases. They have a free ePrint version that you can use to test the functionality before you pay for the full ePrint version.
Next there's PrintBot, this "Network printer driver" supports 1,000s of printer types connected to a local network. The free version lets you print a few pages to test, the full paid PrintBot Pro licensed version is unlimited.
Try both of those out and see which one works with your printer and apps.
There are also some free proprietary apps that work with specific hardware, HP ePrint should work, but only to HP printers (both older network enabled ones and newer ePrint enabled networked ones), Samsung MobilePrint should work (but only for Samsung printers).
MotoPrint lets you print to a lot of different printer types as long as they're connected to a wireless network (don't have to be wireless printers), annoyingly you can only install it on Motorola devices, so not putting down as an answer for you but someone else might find it useful.
After choosing a default program for an action, every time an app gets updated that relates to that action, the OS unnecessarily asks which program to use. I can't be the only one to be aggravated by this defect.

After the latest OTA update my Nexus 9 boots forever. If I turn it off and then turn it on, it shows 
and then it boots forever (green, red, blue, yellow circles, squares, circle slices move forever). I tried rebooting it a few times and even tried going into recovery -> hboot -> factory reset. Nothing changed. My Nexus 9 was not rooted and doesn't have a custom recovery.
Is it clear from this information what is wrong with my tablet? Can I unbrick it by flashing a stock ROM using adb or something?
I have been using Samsung Galaxy s4 stock firmware up until now. Yesterday I switched to AOKP 4.4.4 (18/10/2014 build) and I've noticed that none of my old ringtones work (12 unrelated ringtones). I tried converting some of them to ogg, mp3 and wav formats with audacity. Whatever i do, they do not appear in ringtone list when moved to system/media/audio/ringtones. They cannot be selected with ES explorer - I get "Wrong file type, please select again" message. If I select them with root explorer the ringtone is set to "None".
Some mp3 files in my music library work, but not the ringtones.
I assume it has something to do with ringtone format, however, I have got no idea where to start looking.
Is there any setting I could change or an app I could change / install to add the compatibility? Is there any particular app responsible for sound playback in android?
EDIT: I am running AOKP on Samsung Galaxy S4.
EDIT2: I recently installed latest official firmware. During instalation I tried resetting to phone default firmware and ringtones worked. Now that I am on new official firmware, old ringtones do not work again. Also, On the new FW I used official ringtone selection tool (that creates a ringtone file). The ringtone created works in ringtone selector list, but cannot be added to list if removed from the list or if moved.
This leads me to believe problem is with some update all newer firmwares (including AOKP) have.
No real answer to this question, I am forced to use a 3rd party app to use my old ringtones.

In my OnePlus 2 running OxygenOS 2.2 (Android 5.1.1) the problem was solved by removing .nomedia in the root of the SD card, copying the audio folder from the media folder to the root of the SD, and then moving it back to the media folder. Don't ask me why but it worked again.
I have a newly purchased Samsung Galaxy A5, which, after attempting to install Marshmallow eventually got stuck on the "Downloading... Do not turn off target!!" screen. Just before this happened I briefly saw a message that said "error" beside a picture of a little android lying on its back (presumably suffering from an error).
I tried leaving it there on that "Downloading... Do not turn off target!!" screen but after 8 hours I gave up, took the charging cable out, and let the batter die (the A5 has an internal battery so removing it was not an option).
I can restart by charging the phone for a bit and then holding down Power + VolumeDown + Home, which takes me to a screen with 2 options:
both options take me back to the "Downloading... Do not turn off target!!" screen. I can restart with Power + VolumeUp + Home, which seems to make the phone attempt to reinstall the update. I get a screen saying "Installing system update...", which gets to about 90% before showing me the little dead android and the "Error" message. After that, it's back to the "Downloading... Do not turn off target!!" screen.
My first option was to return the phone but the vendor is giving me the run-around and my credit-card company will take up to 80 days to revert the payment, so I was hoping to fix this myself, but not at the cost of voiding the warranty, as this could jeopardize my chances of getting a refund / repair. I have contacted the Fair Trading body in my state (in Australia) who will mediate and probably get me a refund but, again, this will take a while.
So, do I have any options, or do I just need to wait this out?

I have solved my own problem today and I'd like to provide the solution for others that might encounter it. The actual Internal memory for this phone should amount to exactly 0,96 GB or close to that. I got aware of this comparing my phone to another one from the same model. I first tried formatting the Flash memory (or Mass memory) on my phone, but to no avail. So I tried doing a reset and it solved the issue.
To do this:
I have a Motorola Razr D3 cellphone. Although I have at the moment 800 megabytes free on the device memory, some apps report insufficient space to perform the installation. I've cleaned caches and removed many apps.

If you were to install a Home Screen application that does not give you access to the System Settings screen (to go to Manage Applications), and also does not let you launch Apps (such as the Market App or 3rd party install/unistallers), is there ANY way to uninstall such an application?
I know that Android requires your permission before letting a new App take over the home screen privilege. But say you're trying a newly published Launcher app that is buggy (or malicious). You are of course still going to tell Android it's ok to give this App the Home screen privilege. Now once it is installed, your phone is now effectively useless?
Is there a way for a typical end user (who doesn't have Eclipse/ADB) to get out of this situation? Other than doing a complete factory reset?
I realize there are ways to uninstall an App via ADB ("adb uninstall package.name")
But it seems like a typical end user is potentially screwed if they ever install such a malicious/buggy app. This seems like a gaping security hole in Android, no?

Start your device in SAFE MODE and then uninstall the app that's causing problems. Rebooting will exit from Safe Mode. Here's how to access SAFE MODE in a few popular devices.
HTC devices with physical buttons:
Nexus One:
Motorola Droid
Samsung Galaxy S
Power the phone off.
Turn the phone back on while pressing and holding the Menu button.
Keep holding the Menu button until the Home screen loads. The lower-left corner should say Safe Mode.

My device is rooted and I am currently running one of the CyanogenMod 7 (Gingerbread) nightly builds.
Answer
I was reminded by a friend that the CyanogenMod ROM I am using includes 'DSPManager' which is essentially a graphic equaliser with profiles for Headset, Phone Speaker and Bluetooth Device.
By lowering all the levels for the Phone Speaker profile I have managed to reduce the minimum in call volume (hooray!).
For people using ROMs other than CM on a rooted device, I believe a combination of DSPManager APK and modified audio library can be flashed but people appear to have had mixed results.

GParted is giving the "Unable to read the contents of the fileystem." error for both partitions, though the FAT32 partition is accessible from File Browser flawlessly.
It's a Samsung i9505 running on nightly built Cyanogenmod 13.
EDIT: I found out the unrecognized partitions is a static AES-128 bit encrypted ext4. Now I will try to decrypt it and recover whatever.
EDIT2: I changed my mind and won't bother. Formatting as external storage this time.
I am using Huawei phone with android 4.1.2. Currently I'm losing the app shortcut on my home screen after a crash of the system recently. During the crash, I dragged the Whatsapp and Hoiio apps shortcut to the bottom menu (phone shortcut, browser and messaging by default). After a while, the phone turned off due to battery dry. But after I restarted the phone, the shortcut for the apps disappeared, although the apps are still installed (as shown in Google Play Store). After a few times of re-installation of the apps, the apps shortcut keep disappearing from the home scree. This android does not have applications page, only home page. How can I fix this and make sure that my apps shortcut can remain on the home screen?
Back when my HTC Desire had its stock Sense, there was an option to link Facebook accounts to Google contacts, by selecting them from the Facebook friends list.
This created fields for my contacts such as:
id:02394985720/friendof:2103910923|id:123768123/friendof:09812387
Now, my phone is on CyanogenMod 7. I've added a Facebook account under Synchronization settings, but it seems it only matches contacts who have the same name as their Facebook counterpart. Those who are matched get a Facebook profile link:
The other ones aren't linked. Therefore: How can I force link a Google contact with a Facebook profile? This would allow me to link contacts even if their names are different.
I'm aware of this question: how to link contact with facebook, gmail etc?, but there is no "Join" option for me, and it isn't really answered as well. I'm also aware of SyncMyPix.
Answer
First, in the Facebook app, under its Settings, enable synchronization for all contacts.
Open up your contact list and select the Google contact you would like to merge. Then push the menu button and select "Edit Contact". Then hit the menu button one more time and select "Join".
Choose which contact you would like to merge it with and you should be good to go.
Device says
This device was reset. To continue, sign in with a Google Account that was previously synced on this device.
Does anyone know how I might fix this problem? It's an important test phone for me.
Again it’s the same wifi as previously.
I looked How to bypass "Verify your account" (Factory Reset Protection) but Nexus 6 does not have such a home button.
How does the S-View Flip Cover work? I know some apps that use the proximity sensor to check this and turn on and turn off the screen.
S-View Flip Cover does not require any softwares, so how does it communicate with the device?
Answer
It's simple. There are hidden magnets in the front part of the flip cover. These magnets tell the device that S-View Flip Cover is attached.
The glass window that is on the cover is conductive, through which you can operate only that much part of the screen leaving the rest of the screen non operable to avoid accidental touch.
The idea behind is just like the Apple smart cover. What makes the S-View Flip Cover different is the conductive window functionality to accept or reject calls etc.
I'm trying to root my Samsung Galaxy S4 GT-I9500 and I'm wondering that is there any way to root it without using PC and without losing any of my data. Currently I am running on Android 4.4.2 and have no custom ROM.
Thanks in advance!
I was re-flashing the firmware on a Samsung Galaxy S4 using Odin, and the USB cable was bumped, which made the update fail. I reconnected and attempted to flash again by clicking the Start button. It seemed to be progressing, but Odin's blue progress bar continued from where it had stopped instead of starting from the beginning. After a while I got the following warning message from Odin, in red text and repeated 19 times:
Invalid percent of drawing download progress bar!
followed by this at the end:
SECURE CHECK FAIL : system
I attempted to start the process again (by clicking Start in the Odin desktop app), but it failed multiple times. I also tried clicking Reset and starting again. It doesn't seem to be possible to do anything from within Odin on the phone. It doesn't respond to any buttons and doesn't react in any way when I try to start the process again from the computer (no more messages on the screen, and no movement in the progress bar, or anywhere else). This doesn't necessarily mean it's frozen, though, because I don't believe it's intended to be interactive. The blue progress bar on the phone is all the way to the end, where it has been since my second attempt to flash.
I have not restarted the phone, because I am afraid that if I do that after an incomplete flash, I will not be able to get back into Odin. It is still on, still in Odin, still showing all the errors. The desktop Odin app on the computer can detect when the phone is connected and removed (I get the "Added!" and "Removed!" messages).
Am I correct in my concern that I'm likely to brick the phone if I attempt to restart without flashing successfully? Is there anything I can do to restart the process? It would be an astounding design flaw if Odin really isn't capable of restarting a failed flash to allow for recovery if the process fails and the device has not yet been restarted and Odin is still in RAM.
I know for a fact that the ROM file I'm using is valid and that I'm doing this correctly, because I have gone through this process several times and never encountered a problem until this time when the connection was interrupted. I have no support available from either Samsung or the carrier (Verizon), because I bought this phone used on eBay specifically for experimenting with things like custom recoveries and ROM flashing.
FWIW, here's a screen shot of the Odin desktop app as it is now:
There are reports (see link below), that Google will now stream a small set of apps, when content in those apps match your search criteria. I have yet to be able to produce a Google search that shows one of these streaming app results.
I've tried using the example that I've seen in articles: "hotel right now in Chicago", from both the mobile web version of Google.com, as well as the Google app, but to no avail. The correct answer to this question will look something like:
"In order to see a streaming app result, you must be within the Google App, and you must use the following search: What is Sagittarius' horoscope for today?"
or
It appears from this link (www.example.com/GooglePulledStreamingApps) that Google is no longer streaming apps, or is only streaming them to a limited number of people.
I've also discovered (see 2) that this only works from the Google App on devices running Android 5 or 6. Although this feature of Google is only available on Android, I still don't believe this is an Android Community question, because it is specifically regarding how a search on Google behaves.
What are streaming app results?

Since I checked this option in Settings > Personal > Location, GPS finally works when no data connection is available, eg. when travelling in foreign countries. It's still slower than when a data connection is available, but at least, it does locate me when I'm standing in open skies.
However, I was wondering what this option really means: Does it mean that it will never use A-GPS to download data from the Net even when a data connection is available through GSM *?
IOW, if I'm travelling in my country where a GSM data connection is available, will Android download A-GPS data to speed things up?
Thank you.

My phone is a OnePlus 3t and I'm developing for it for a while, adb works normally, udev rules are configured. I enabled OEM boot, and manage to reboot in a way which looks like to me fastboot. After rebooting to "fastboot" the device's USB id is exactly the same as in normal boot. That's suspicious because I read in some forums that it might be different after fastboot boot (I checked if I have to adjust udev rules).
fastboot devices
doesn't show any devices. My suspicion is that I don't really boot into fastboot mode. Here is capture when I reboot, I press the power button:
If I don't press the power button, the up/down offers recovery mode. In recovery mode I can wipe all data or the cache and also install from internal storage or ADB. data decrypts successfully. Needless to say I cannot install SuperSU, TWRP img doesn't appear in that install menu.
(My goal is to unlock the bootloader, install TWRP and SuperSU so I can perform the xml file config mod for DayDream.)
Any help is appreciated.
Basically, I want to install an app with my settings already configured to a bunch of phones.
My thinking was
I would rather not root, but it's a possibility.
I've a Huawei u8160 which is running Cyanogenmod 7.2.
I saw in the change log that it has better support for USB mouse and keyboard and it was written beside it COMMON.
Quoted from the Cyanogenmod github CHANGELOG.mkdn:
...
Common: Better support for mouse and usb keyboards - Emilio Lopez, Tanguy Pruvot
...
So I was wondering if it supports USB host so I can connect it with a USB mouse and keyboard ?
Answer
The Common: Better support for mouse and usb keyboards found at the changelog refers to all devices supported, meaning that there was an overall improvement on the USB support for mouse and keyboard devices.
But take into account that the words "better support" means that there was an improvement, but it may still be buggy on certain devices under specific situations.
As a side note:
To your particular case, you are referring that you have a Huawei U8160, but on the changelog, the support goes for Huawei U8150. So, it may not be fully supported with or device.
The changelog can be found at: github - CyanogenMod

I have and Samsung GT-i5500 (aka Galaxy-europe, aka galaxy-5, ...), running Android 2.1
Some months ago I've returned it for repair because of GPS issues. Ever since, when I connect it to my computer and start Samsung Kies on my computer, the Firmware Information page says:
This version can not be updated.
Current firmware version: PDA:JK3 / PHONE:JK3 / CSC:JK3 (CPW)
Does this mean that when (if?) Samsung ever releases Android 2.2 for this model, I will still not be able to update it?
Before the 'repair' it never said that the version could not be updated. It was more along the lines of 'you have the most recent version' or 'no update available' instead of 'this version can not be updated'.
Answer
According to this link this message is due to a bad translation from Korean to English (and from that to Dutch, because in Dutch the message has the same meaning).
Original Korean was something like "For this ROM there are not updates available (yet)".
Turning off / Locking the screen is activating the Bluetooth on my device.
I don't know why my device is doing this as I am unable to find any settings in Developer settings (enabling the Developer mode is the last thing I did).

Answer
FireChat seems to be the culprit.
Changing it's permission via Settings > Privacy (removing 'Bluetooth Change allowed' solved the issue.
Thank you @Firelord for pointing out at the right thread.
These are the files that I know go into verifying a user's password:
/data/system/gatekeeper.password.key
/data/system/gatekeeper.pattern.key
/data/system/locksettings.db
/data/system/locksettings.db-shm
/data/system/locksettings.db-wal
I know that this is where the files used construct the FBE key are stored:
/data/misc/vold/user_keys/ce/0/current/version
/data/misc/vold/user_keys/ce/0/current/secdiscardable
/data/misc/vold/user_keys/ce/0/current/encrypted_key
/data/misc/vold/user_keys/ce/0/current/stretching
/data/misc/vold/user_keys/de/0/encrypted_key
/data/misc/vold/user_keys/de/0/stretching
/data/misc/vold/user_keys/de/0/keymaster_key_blob
/data/misc/vold/user_keys/de/0/secdiscardable
/data/misc/vold/user_keys/de/0/version
Although I'm told the encrypted FBE keys are stored in the above paths, these files seem related:
/data/system_de/0/spblob/0000000000000000.handle
/data/system_de/0/spblob/XXXXXXXXXXXXXXXX.pwd
/data/system_de/0/spblob/XXXXXXXXXXXXXXXX.secdis
/data/system_de/0/spblob/XXXXXXXXXXXXXXXX.spblob
The XXXXXXXXXXXXXXXX is a placeholder for a 16-character long hexadecimal "handle"; 0000000000000000.handle, by contrast, is named exactly as it written. There are actually several sets of pwd/secdis/spblob files on my phone and two that are missing their spblob file. I'm not sure I'm supposed to have that many.
Over the pass few days, I've messed up my phone trying to get TWRP to decrypt my data. At first, after removing my password, I couldn't set another one as Settings would crash whenever I tried. I was able to fix it by renaming locksettings.db. I then went ahead and set and cleared several different (but very insecure) passwords/PINs, including my old one (which is secure). I'm unable to remember the order of events, but now I'm at a point where I get Pixel is starting whenever I swipe on my home screen after booting. I'm suspecting this has to do with it not being able to decrypt my FBE key. I'm wondering if through my combination of renaming files like gatekeeper.*.key and locksettings.db that the FBE key maybe was decrypted with the wrong key and then reencrypted with a different one.
I'd like to know what role the above files play in the encrypting my phone. I'd also like to know:
gatekeeper.*.key and locksettings.db used in the process.The purpose of all of this is to determine if the problem with my lies with the encryption key being wrong or if it's a matter of cleaning up the right files, and to get past the endless Pixel is starting message to my apps and content.
When I try to invoke Google Now by swiping up from the Home button, I get the message "Network error. Check your network connections and try again". I have a solid WiFi signal, and searches from the search bar work fine. I get the same message when I go into settings after launching Google Search and try to enable Google Now.

Finally found the answer. I had four Google accounts - one of them could not sync because it required domain policy to be enforced, and I hadn't allowed that. I connected the tablet to my laptop and used adb logcat to see what was being logged when the error was displayed:
I/GLSUser (28125): GLS error: DeviceManagementRequiredOrSyncDisabled <> oauth2:https://www.googleapis.com/auth/personal_derived_data https://www.googleapis.com/auth/paths.notifications
V/GoogleLoginService(28125): Returning error intent with: ComponentInfo{com.google.android.gsf.login/com.google.android.gsf.login.LoginActivity}
E/Velvet.VelvetNetworkClient( 4564): Failed to get auth token
(these messages were repeated several times).
I guessed that the errant account may have been involved (even though it was not the account I was trying to active Now with), removed the account from the device and all is well.
Which hardware sensors are supported by Android? Are there any imaginable sensors that may be planned to be supported in the future?
For every sensor:
Here is a list of currently supported hardware sensors:
Environment Sensors
Motion sensors
Position sensors
The orientation sensor is software-based and derives its data from the accelerometer and the geomagnetic field sensor.
After upgrading to Lollipop from 4.4.4, mobile data doesn't work. I have tried all the solutions listed in various forums including, 1. Reboot 2. Reboot after re-inserting the sim card. 3. Manually add the APN (Got the settings from the service provider) 4. Toggle between the Preferred Network type (2G and 3G)
I have only one usable sim slot, and so cannot use sim slot-1. I have heard it worked for a few guys after putting the sim in the other slot, but unfortunately I cannot try that out.
Any suggestions?
I've had this phone for two years so all my photos are saved on the actual phone (not a micro SD card). I'm wondering if I reset it, will I lose all the photos saved on my phone? I'm not bothered about losing the apps just my photos I'm concerned about.
As this warns, you should not enable swap on the wrong partition or you can destroy your phone:
OK before we go any further! previous phones had a partition layout where mmcblck0 was the SDcard (external) our phone uses mmcblck1 for the external sd. This is important because if you use an app it may be preset to use mmcblck0 as swap partition.using this setting will cause you to use your sbl2 or sbl3 as swap partition.this will brick your phone and unbrick guide will be useles.
So the swap partition might be /dev/block/mmcblk0p3 if I have 3 partitions (fat32, sdext, swap) on my SD card, or /dev/block/mmcblk0p2 if I have 2 partitions (fat43 and swap) or /dev/block/mmcblk1p? if you have a different phone, etc. and the wrong choice can brick your phone.
How do you find out which partition is which? It should be the only partition on any drive of the phone with the swap filesystem.
fdisk -l does this on Ubuntu, but outputs nothing in Androidblkid does not show the swap partitioncat /proc/partitions lists a lot of partitions, but doesn't indicate which is the swapcat /proc/swaps only lists swaps that are already being usedcat /proc/mtd only says dev: size erasesize name and nothing elsels /dev/block/vold lists some partitions as 179:64 179:65 179:66, but doesn't indicate what they are?swap swap 129 MiB), but doesn't say the dev nameEven if there's no command line tool to print it directly, surely there's a way to deduce it from some other information??
Answer
I installed the Disk Info app and in the options, I enabled Expert mode and Unmounted partitions. It doesn't say "swap", but it shows clearly that it's the only other partition on the SD card and it's the right size, so /dev/block/mmcblk1p2 must be the one:
Swapper 2 is configured to use /dev/block/mmcblk0p3 by default, so I'm glad I didn't go with the default.
