Google docs on Android cannot authenticate
I have a Galaxy S3 on Sprint with the latest software and firmware updates. When I use the internet browser to browse to docs.google.com, it keeps redirecting me between accounts.google.com and then back to docs.google.com. It does it so fast I can't type in my password to authenticate.

This has persisted across a reboot. I am logged in to my google account if I go to Settings, Accounts.

I just want to get on to Google Docs. How do I stop this redirection? (note this method worked fine on another phone of the same make/model.)

chkdsk for android
My Android tablet "went berserk" this week and eventually I managed to stop the behaviour that was stopping me from even getting the "desktop" to stay up front.

I eventually discovered a corrupted directory (name was "mashed").  I deleted it and the device now seems stable.

What is the Android equivalent of the Windows/DOS CHKDSK command?  I want to be able to scan the device and repair any nascent problems on a regular basis.

How do I stop Maps and Street View from auto updating?
I'm on Froyo.

My phone internal memory is nearly full, so I've stopped updating my apps and uninstalled updates from the preinstalled apps.

However, every few days, my phone keeps auto updating the Maps and Street View apps, filling up the internal memory and I have to uninstall them.

Is there any way I can disable the auto update? As far as I can tell there's no entry for these apps in the Store.

I rooted my Kindle Fire and flashed TWRP, FireFireFire, and AOKP, and it's been working fine for a while. Recently, however, there have been strange problems with the bootloader. It has gotten to the point where the bootloader requires the user to select how to boot, then crashes and starts up again. How can I reflash FireFireFire to my device? Thank you for any help.</p>

Why doesn't Android report accurate Netflix data usage?
I played ~2h of Netflix on my Nexus 5, on T-Mobile's LTE network early this morning. I had switched off WiFi. After doing so, the data usage screen looks like this (scaled down):

Netflix data usage (click for larger image)

Note that the phone reports 2.85GB of data used, with the top user being Netflix at 22.2MB. That's different by two orders of magnitude; and nothing else on the list comes close to making up the difference.

T-Mobile gives a different number still (~1.3GB). The screen notes that may differ. But it confirms that the data did indeed go over T-Mobile.

Why is Android under-reporting the data used by Netflix by two orders of magnitude? Is there some way to get accurate data usage stats (I'm rooted, so root-only solutions are OK).

edit: Checking /proc/net/xt_qtaguid/stats shows Android is reporting on rmnet0 while reality is on clat4. Not really a solution as that file reports since boot only, not a particular time range.

Can 2 smartphones malfunction if they are hold together in the pocket for long times everyday?
I apologize for my ignorance but I am not very tech savvy.
Basically  I do  a field job and I always have 2 phones in one of those bags you put around your waist.

I had 2 Samsung galaxy S2 in the past and after a while they started having trouble with receiving signal. I went to a "specialized" shop where they sell smartphones and the guy told me that the malfunctions is caused by keeping them together for prolonged periods of times.And went on with some speech about electromagnetism.

Now the two S2 were malfunctioning for real as I tried with different sim cards, factory resets and the problem persisted.

I then bought a S3 and yesterday I bought another one. I always need 2 phones..long story.

Now some other people basically confirmed that keeping them close to each other breaks them but none of them,in my opinion, seemed to know their shit.

so,

问:
internal sd storage partition/mount problem
I got my nexus 7 2013 a few weeks ago. It worked great for some time until I decided to flash a kernel that claimed to add support for CIFS windows shares mount. After installing this kernel, when the OS booted, I did not have landscape mode working anymore - only portrait. I decided to do adb full restore to a full backup i made before this step, which seemed to have passed without any errors, but something happened to the recognition of the internal SD memory - applications are not able to use it - I am getting "no external storage" messages when I launch the gallery application and an error when trying to run the google play store - "unfortunetley, google play store has stopped". The device is still starting with only portrait mode.

i then tried to format the device and used TWRP to format everything including the internal memory. After that I reflashed the original rom of google for this device (taken from here). The problem is still the same. In TWRP recovery console - I am able to access and push files to and from /sdcard folder with no problems, and see its content with adb shell.

When android loads - cd /sdcard + ls shows that it is empty (even though it does contain files copied to it in recovery console mode) the reason for this is that with ls I can see that /sdcard points to /storage/emulated/legacy which points to /mnt/shell/emulated/0 which DOES NOT exist. /mnt/shell/emulated/ folder exists, but it is empty.

I am unable to use the device - just start the OS (and get the error messages when trying to launch applications). When the OS loads I immediately get the "unfortunetley, google play store has stopped" error without doing anything.

running google earth application when logcat active gives the following output:

```<code>E/cutils  (10727): Failed to chmod(/mnt/shell/emulated/0, 0): Read-only file system
E/dalvikvm(10727): cannot mountExternalStorage(): Read-only file system

D/dalvikvm(10727): No JNI_OnLoad found in /system/lib/libearthmobile.so 0x41dc5158, skipping init

Any idea how do I solve this? Why are the folder links broken when I am using an original google rom?

How can I hide the Status/Notification Bar on Android 4.4?
I'm trying to replicate Paranoid Android's "Expanded Desktop" with PIE controls (as much as possible) on my Nexus 5. Until PA is actually released, however, I've got to hack it together myself.

So far, I've successfully...

Hidden the Navbar (Lots of methods work. Editing build.prop still works. In this case, I'm just using a feature in Cataclysm ROM)

Enabled PIE Controls via LMT Launcher

The last thing I want to do is...

Hide (or disable) the Status/Notification Bar

Initial Googling has told me to install a launcher with the option to hide it. However, I rather like the new Search/Launcher hodgepodge thing.

Is anyone aware of a way to hide (or disable) the status bar?

Edit: 2013-12-04

Now that Xposed Framework works on Android 4.4, I'm using it with the GravityBox module, which has also been updated to support Android 4.4.

Unfortunately, using GravityBox Expanded Desktop to hide both the Navigation Bar and Status Bar disables the notification drawer - something I certainly don't want.

The PIE controls from LMT are more functional than those from GravityBox, so I'm using LMT PIE controls with GravityBox on expanded desktop until PA is released.


问:
How can I set a data cap per application?
In Android, you can see how many data each application has used. You can also forbid an application from using data by hand. And you can set an automatic data cap for the entire system. But is there a way to automatically cap how much a certain application can use?

An example scenario is how Cyanogen (a custom ROM) kept trying to download Android updates from Google on 3G, over and over again, even though it couldn't do anything with them. It was of course not supposed to do that, but it did this for many users. It emptied my monthly bundle in a day. In the statistics, this data usage showed up under the Google Services Framework, if I recall correctly.

I did not want to block this application altogether, because much of the Google stuff depends on it. So I wanted it to be blocked from using any more data over a certain threshold. In the end, I disabled the receiver that queries for updates; but that was an emergency solution that shouldn't have been necessary.

I'd also like to be able to cap certain applications individually in the future, for who knows what might happen. I might want to cap my Internet radio in case I forget to turn it off, or whatever. I can't find an application that can do this; can you?

How to Clear notifications once and not be bothered/repeated again?
Simple yet annoying behaviour of Android (Galaxy S3)

Notifications appear for many apps (email, games, messages etc.,) but once I view them (by a slide down, not by opening/responding to each of them ) I want them to be gone. They keep on repeating & appearing again and again until I respond to the notification.

ie., If it is a new email, I'm being notified repeatedly until I open the Email program!  I find this extremely annoying. I don't want to Turn off Notification because they are useful. But, I don't want to be bugged by them as well.
Good, show me once & then disappear.

Samsung Keis is OK for content only, but not really appropriate for this task it seems.

Extract DB from accidentally formatted /data
I had to factory reset my Samsung Galaxy Note i717 (1stGen AT&T), and I forgot to backup before formatting /data.

I need to extract the messages DB from it, because I have many important messages from my phone that I require.

So far, I have (after rebooting into CWM):

```<code>$ adb shell mount

/dev/block/mmcblk0p25 on /data type ext4 (rw,nodev,noatime,nodiratime,user_xattr,acl,barrier=1,data=ordered)

Then I unmounted data from CWM, and then:

```<code>$ adb shell dd if=/dev/block/mmcblk0p25 of=/external_sd/data.backup bs=4M

Next I DL'ed the backup file to my computer:

```<code>$ adb pull /external_sd/data.backup

</code>```

So now what I have is an image of my /data partition (ext4). How can I file-carve for the messages (SMS) DB file? I have a nandroid copy from a while back that has some of my old messages (I set my SMS to never delete), would that help?

问:
My new phone isn't listed as a device in the Android Device Manager, how can I register it?
I broke my phone a couple weeks ago, thankfully I was paying the $7/mo for insurance and was able to get a replacement in the mail a few days later.  This new phone isn't registered with my Google Play account (https://www.google.com/android/devicemanager?hl=en&u=0 doesn't list it) and I can't remotely install apps through https://play.google.com/store.

Everything else is working fine, it's sync'd with my gmail/chrome just fine and I'm able to install already-paid for applications on it without a problem.  The only thing it seems I can't do is install apps remotely through the play.google.com/store website, which makes sense given it's not registered as one of my devices.

Am I missing something obvious?  In the past my devices have always been registered automatically, as best I could tell anyways.


问:
Enable USB debugging on Motorola Droid Razr Maxx HD Global with no screen
Before this gets marked as a duplicate please consider that virtually every answer involves vague references to things like 'fastboot' that I honestly don't understand and can't find any information about. I have spent the last 4 hours scouring 100's of forum posts, reading ADB documentation, looking through wiki articles trying to learn the ins-and-outs of recovery roms, flashing, etc., and I still don't have a working solution -- not because the things I've tried haven't worked, but because information is so obscure and vague that I have no idea what to try.

I have a Droid Razr Maxx HD Global. The screen and digitizer are both broken. I have a new identical working device. I want to transfer everything -- system settings, app data, etc. -- from the old device to the new device. It's easy enough to move the SIM and external SD to the new device but I still have the issue of internal storage.

The phone is stock. USB debugging is disabled. I can't use ADB because of that. I also can't use tools like MobileTrans (or whatever) because of that. I can't enable USB debugging because I need the screen. I don't have a USB On-The-Go and I don't even know if it would work with my device. I don't have an HDMI cable or a monitor that accepts HDMI. I have tried multiple USB On-The-Go adapters and multiple mice and none of the mice are recognized. I have an HDMI cable and an HDMI monitor which works but does not help with the digitizer issue.

The most promising looking path I see so far is to install a ROM that has USB debugging enabled. Maybe it's a regular ROM, maybe it's a recovery ROM, I have no idea. I have this RSDLite tool that I guess flashes regular ROMs, or maybe recovery ROMs, or both, I can't tell. I have a regular and recovery Cyanogen ROM image. RSDLite can't load it. RSDLite doesn't show my device. I saw a few people say "oh just boot into fastboot and use that". Ok I'll just, uh, press the "boot into fastboot and use it" button? I have no idea what fastboot is other than a tool that I have in my ADB installation.

There is also this answer, which recommends typing setprop persist.service.adb.enable 1 somewhere, although I don't know where. The poster says, amusingly, "The Droid X does not have a physical keyboard - but if it did you could try this in a terminal." Anybody have any ideas about this one? My imaginary keyboard on my Razr doesn't work either. (Update: This requires screen access and a terminal on the phone, so, as per usual, that doesn't actual answer the question that was asked.)

I did try "using" (fsv of "using") fastboot to boot with the Cyanogen recovery ROM (which may or may not be the correct ROM and may or may not have debugging enabled and I don't actually know if "boot" permanently modifies the device or not):

```<code>fastboot boot /path/to/some_arbitrary_rom_i_got_on_the_internet.img
</code>```

But it just got stuck on <waiting for device> and eventually gave up, something that all the answers involving fastboot seem to neglect to address. Not really sure how to proceed there, or if that's even the right path to be going down. (Update: Apparently the power + volume down button boot menu is called "fastboot" mode -- odd that it's this easy when all mentions of "fastboot mode" on the internet seem to involve some huge chain of drivers, weird tools, and arcane commands and never mentioned that on Motorola devices it's just the plain old boot menu. I will try this when I get home from work.)

The flood of advice like "yes just select X and Y in the boot menu" seems to help nobody with this problem because, obviously, the screen is broken.

HOW (keyword: HOW) do I somehow enable USB debugging on a device with a broken screen? Do I use fastboot for something? Do I find a ROM of some sort with USB debugging enabled? What ROMs have USB debugging enabled (it's not exactly something listed in their feature list)? How do I actually do this?

Minor rant: It's amazing how massive the headache is compared to how conceptually simple the problem (need to enable one setting and can't) is. Given that drop damage is the most common cause of accidental smartphone failure and that USB debugging is required to transfer system data (for some reason the Android folks tied the concept of "transferring data" to "development tool"), it boggles the mind why there isn't a more robust interface for this or at least a non-arcane working how-to out there somewhere for people who reasonably don't want to spend a week of their life becoming an expert on Android kernel image development and debugging.

Android 4.0.4 tablet WiFi fails to connect due to bad authentication
I was already using the android 4.0.4 tablet with WiFi at my home. Very frustrated that when I just turned it on again today it was not able to connect.

Actually, it does connect - There appears to be two phases:

Connecting to WiFi

Authenticating
a.  "Authenticating.."
b. "Saved secured with WPA/WPA2"
c.  "Authenticating"
d.  "Authentication problem"

The first step is successful. The second fails at the step d.

Now, I had saved the password for the WPA/WPA2 network. So this is NOT a wrong password issue. But even so I did a "forget" and re-entered the password (with "show password" turned on to be sure).

What really bugs me here is there is no further information on "why" the authentication failed.

There are several other laptops in the home. They have not changed any settings for months (all DHCP with long leases).

Motorola Droid Razr Maxx HD HDMI Portrait Mode
I have Razr Maxx HD with a broken screen and partially functioning digitizer. I am attempting some data recovery. I have an HDMI cable and monitor, and I have a USB OTG hub on order (for mouse control) but it has not arrived yet. I'd like to do this ASAP and not have to wait for the hub to arrive.

It is stock, no root. USB debugging is not enabled.

The HDMI out is working fine. The problem is, it seems to always display in landscape mode, and I can't enter my unlock pattern because that portion of the digitizer is unresponsive.

Can I make it display the unlock screen in portrait mode? I noticed when I press the power button to turn the display off then press it again to turn it back on, for a brief moment it displays portrait mode on the monitor but immediately rotates. So, obviously, the capability of rendering portrait mode over the HDMI output exists, I just don't know how to make it stay that way.

Can't Restore Backup using ClockworkMod Recovery
I wonder can anyone help. I done a backup using Clorkwork Mod before I flashed a new ROM onto my phone. Now when i am trying to restore the backup onto the phone using CWM it completes the task but whenever I reboot the phone it gets passed the first samsung screen but hangs at the second SAMSUNG screen where the text is pulsing.

I have tried Wipe / Data factory reset, Wipe Cache, Wipe Dalvick and fix permissions. None of these seem to make any difference. The only thing that has worked in flashing a new ROM but I do not want to lose any of my apps /configs.

Any suggestions guys would be much appreciated.

Note 3 "Security information" notification
I've just set up a new Galaxy Note 3 and I keep getting the following notification:

Security information

An application attempted to access system on your device without
  authorisation. This attempt has been blocked.

I have no idea what's causing this as there is no application listed as the culprit. Some forums point to disabling Knox as a solution, but I've done that and still get the same. (Anyway, the phone only includes a link to download the full app, so I doubt that would have been it.) I also know that I can hide the notification for 30 days, but that's just hiding the problem, not fixing it.

What is causing this to keep popping up and what can I do to fix it?

Various Stutterings on Samsung Galaxy Nexus
So I've had my Samsung Galaxy Nexus for a while now, round about a year, and it has this odd set of problems where some of the core functions of the OS stutter. What do I mean by this? The most egregious and obvious example is while typing, occasionally my keyboard will find it pertinent to, without prompting, close about 95% of the way, stall, then open and close in quick succession many times in an unpredictable fashion. This makes typing very difficult as when I go to type, the phone will sometimes make it impossible to access the keyboard. While it does this odd stutter, the normal "back" button shows the "close keyboard" icon. When tapped, the keyboard will continue its stuttering until it realizes I wanted it to close, when it closes. I've tried reinstalling the keyboard, resetting the phone to factory settings, and different keyboards like swiftkey.

Along with this keyboard malfunction is the unfortunate glitch in the phone itself, where if it feels like it, the phone will mute and unmute so fast that neither me nor the person on the other end can make out what the other is saying.

More recently some of the system sounds, such as notifications, have begun stuttering. In what sounds like a failure to buffer the sounds before playing them, it sounds like a skipping record player.

The reason I'm saying all of these in the same post is that I suspect my OS is to blame. One remedy that may or may not work (extensive testing not yet completed) is to make sure there are no finger smudges on the screen. My screen is in tact but has a very small scratch about half an inch long in the middle. I'd appreciate if anyone could point me in the right direction; either to reinstalling my OS from scratch or towards a new phone.

Thanks in advance.

Volume too loud at the start of every music track
This is on a Moto X with Android 4.2.2. Not rooted, no EQ installed or enabled.

I primarily listen to music through DSub (streaming audio from a Subsonic server), but I've talked to their devs, and they don't perform any volume changes of any kind. Likewise, the Subsonic server doesn't make any volume changes, and I haven't experienced this volume issue when streaming to other devices.

Every time a song starts, it plays very loud for a few seconds, then drops slightly to normal. If the song starts loud, it can be quite a jolt for a few seconds before it drops down. It's almost as if it starts at max volume, then drops to the volume level I have set, but I haven't tested that.

As far as I can tell, there are no Equalizers enabled. Turning off the "Audio Effects" settings panel doesn't seem to have any effect on music playback.

Any idea what would be causing music playback to start off at a different volume?

Android - shell utility to perpetually disable headset device?
I have an HTC Desire HD device that has some schmutz in the wired headset jack, and the output from 'logcat' (http://pastebin.com/cNZC8Wwc) shows it vacillating between 'Headset=true' and 'Headset=false', when there is in fact nothing present in the headset port.

```<code>I/HeadsetService( 1977): Headset=false; Bluetooth=false
I/HeadsetService( 1977): Selected configuration: speaker
I/HeadsetService( 1977): Headset=true; Bluetooth=false
I/HeadsetService( 1977): Selected configuration: headset
V/WiredAccessoryManager( 1746): Headset UEVENT: {SUBSYSTEM=switch, SWITCH_STATE=0, DEVPATH=/devices/virtual/switch/h2w, SEQNUM=12164, ACTION=change, SWITCH_NAME=Headset, SWITCH_TIME=9817830244064}
V/WiredAccessoryManager( 1746): newName=Headset newState=0 headsetState=0 prev headsetState=1
</code>```

This makes the handset almost impossible to use for calls without workarounds.

I understand that this is a common problem and that it has been addressed by more than one application in the Market store.  Still, those applications I have tried have not worked correctly to eliminate this problem.

I can't physically clean the port at the moment, and I would like do do this 'manually' via the shell.

Isn't there a straightforward way to do this?  I have tried with the activity manager and package manager search and try to get and set relevant data, but I haven't seen a way to say something like:

```<code>    localhost / # am kill HeadsetService
    localhost / #
</code>```

-which does not stop the flip-flopping device detection.

Can I just echo something to a file like '/sys/devices/virtual/switch/h2w/state' and then use chattr to make it immutable?  Is that even the right file for the wired audio headset?

EDIT:  This doesn't work:

```<code>    localhost / # chattr +i !$
    chattr +i /sys/devices/virtual/switch/h2w/state
    chattr: reading flags on /sys/devices/virtual/switch/h2w/state: Not a typewriter

Losing connection to powered USB hub
Background (not a development question): I'm developing an application which allows multiple android devices to interact.  I am trying to tether the phones through a powered USB hub to run some simulation tests.  In order to use the phones through USB tethering, I have to shell in and do some configuring.  Typically, I leave the phones plugged in overnight, or else I lose these configurations and I have to redo them.

For some reason, when I get in the next morning, some of the lights above the ports on the powered USB hub are off.  The phones connected to these ports are no longer tethered.  In order to resolve this, I have to disconnect the USB cable, reconnect it, re-tether the phone, and redo the configurations.  This is not so inconvenient for 1-2 phones, but I will soon be testing my application with upwards of 30-50 phones.  I will probably be writing a script to configure the phones, but I would ideally not be running this script every day.

I am currently using Nexus S phones with Cyanogenmod v 10.1.0 (based on 4.2.2 I believe), but I do not think this issue is phone dependant.

Is there any setting on the phones that I can set to keep the phones tethered indefinitely?  As far as I can tell, the phones all have the same settings for going to sleep/screen locking. I am really not sure why they are disconnecting, but I am pretty sure it is not the USB hub nor the USB cables.

Update: I forgot to mention that I suspend my computer (Ubuntu 13.04) , but when I return from suspending my session, only some of the phones are powered.  I marked my phones before I left for the weekend, and when I came back the same ones that were powered when I unsuspended my session last time are powered now.  So I think this is an issue with phone settings.

I want the lock screen for my Android (currently running a CyanogenMod 10.2 nightly) to behave more like that of iOS, where I can have a delay on when I need to re-enter the pattern/pass-code, but still require a swipe every time screen is turned off.  The existing "Automatic Lock [after X time]" feature lacks this additional swipe I describe.

My goal is to have the phone locked down after X minutes (e.g. 15), yet not be susceptible to easy unlocking during this time (e.g. power or home button getting pressed accidentally while in my pocket).

I would prefer to not use a 3rd party app, but I suppose that can't be avoided unless there's an existing setting that I'm not seeing.  If there is a reputable 3rd party lock screen app with this functionality, I'll take that as well.

My LG G2X P999 doesn't boot into APX mode
I have a LG G2X P999 phone and as with most of my phones I root them. I have seen many tutorials on how to root my version (Gingerbread 2.3.3) and in all I must boot the phone in APX mode in order to install the Nvidia drivers.
The method is NvFlash which installs ClockWorkMod (CWM) which then serves as a basis to root the phone. But before CWM can be installed the phone battery must be removed, the volume up & down button pressed simultaneously and then connected via the USB cable to the computer. According to the tutorial I should see APX device with a yellow triangle. The tutorial already provides the necessary drivers to install. The problem is when I connect my phone I just hear the traditional windows sound which indicates that something has been inserted. Checking the device manager reveals no unusual device. It is really baffling me why the phone is not booting as it should into APX mode. This is fairly a straightforward process so I guess I most be missing something.

FAQ

I have several USB cables and I have tried them all.

I have a clean install of windows 7 which I can revert back to a previous state. I have tried the process several times.

USB debugging is checked.

The phone doesn't have any physical defects; all buttons respond as should be. Everything is working.

I have several computers and in all I get the same results.

Inspection checklist for new android mobile devices
Many factory faults and bugs in an android device are discovered by the user long time after he/she receive it. Early discovering of faults/bugs in a device is needed when there is a short return period.

Is there any checklist of common hardware and software faults and bugs that could be inspected once the device is delivered?

I am interested in answers for Google/LG Nexus 5 ordered from Play Store, but general answers for android mobile devices could be also useful.

Put G+ back on share menu?
It use to be when I went to share a photo on from my Droid, a little menu would pop up with Facebook, G+, GMail, text messages, and more.

After what I think was an update, that menu changed.  G+ seems to have been removed and something called "Photos" has replaced it.  Tapping "More" lists a lot more apps but none of them are G+.

Choosing photos does not create a post on my G+ stream.  Instead it uploads the photo to some weird holding place that can only be accessed from the G+ web interface.

How can I get my G+ app back into the share menu?

Thanks in advance.

P.S. I have tried Andmade Share. It involves way too many taps.  First after tapping share, you have to tap more. Find Andmade share in that list and tap it.  Then Andmads Share shows an even longer list of apps.  From there you have to scroll to find G+.  Not the simple, tap share tap G+ post.

How to dismiss an individual entry from the Calendar Notifications list?
On my Nexus 5 phone running Android 4.4, if I have several calendar notifications come at the same time, I can easily dismiss them all at once by either:

1) pulling down the notification menu (screenshot below) and then swiping to the right over the entry labeled, say, "3 events" as seen here:

2) tapping on "3 events" from the notification menu to display the Calendar notifications list and then tapping the "Dismiss all" text at the bottom, like in this screenshot:

I'd like to dismiss individual event notifications from the calendar notification list seen in option #2 above, for those times when I get a couple activities done but not all at once.  I see no way to do that, though, other than to tap on each entry, which then pulls up its full calendar entry, and then tapping the back button, which brings me to my full calendar view, and then going back into the notification menu, selecting the events entry, and repeating.  Swiping to the right over an individual entry on the calendar notifications list does nothing.

Is there a quicker way to remove select entries directly from the calendar notification list that I'm missing?  On my old Android 2.3 phone, I could mark a little checkbox next to each entry on the calendar notification list and dismiss only selected reminders, but I see no way to do that in Android 4.4.

Install usb_modeswitch
I'm working on a project which we use a Beaglebone Black that runs on Android. We need to use USB storages for data transfer. When I plug in a USB storage to Beaglebone it works well. But if I remove it (without going to settings and clicking unmount USB device) 'unsafely' and re-plug it, Android doesn't mount USB storage. It creates its folder in /dev/block/sd* but doesn't mount it to /storage/usb1 . So I tried to use dmesg command to findout what the problem is. And I think I find the source of the problem. dmesg says:

```<code>init: no such service 'usb_modeswitch'
</code>```

I think my Android distribution doesn't have usb_modeswitch binary and because of that it can't re-mount USB storage. I searched the web and find this site . But I'm not a Linux guy and I was unable to create a binary for my Android. I think if I can create a binary and copy it to /system/xbin/ folder in my Beaglebone, It might work. But of course I might be terribly wrong :D If you can give me step - by - step instructions to create a usb_modeswitch binary, I'd be grateful.

How can I seamlessly update Cyanogenmod by preventing "signature verification failed" error?
I really like how Cyanogenmod can be updated from the Settings menu. After a new update is downloaded, it even asks to if it should reboot to install the new package.

It seems that the update concept is to reboot into recovery (ClockworkMod), verify the update packages signature and automatically install it (without a second user confirmation). But the signature verification fails for every Cyanogenmod update so far.

The recovery screen looks approximately like this:

```<code>Install Untrusted Package?
  THIS CAN NOT BE UNDONE.

- No
- No
- No
- Yes - Install untrusted zip
- No
- No

ClockwordMod Recovery v6.0.2.0

I like when the phone starts ringing very gently at first (to prevent startling me or annoying others), and but gradually comes to full volume ringing after 20-30 seconds (to reach me from other room/covered/etc.).

But the vibrating itself is louder than the beginning of my ringtone and breaks that "gentle beginning" scheme. Tunring it off also not an option because of it is often the sole mean to discover the call.

Even better if I can configure myself the exact pattern of vibration, so that it is synced with the music.

Sync certain contacts between two devices/google account
Is there any way of syncing selected contacts from one android device/google account to another?

Consider the following example:
Person A  and Person B share real life contacts, but on their smartphones, each person has to maintain contact details on their own. The data is there, so why do not share this?

The following ideas came to my mind:

Create a new, shared account. All contacts that should be shared are stored in this account. On each smartphone, contact syncing for this account is enabled. This should work just fine on android smartphones. But the contacts of the shared account are not accessible through the web interfaces of the individual accounts!

Use Gmail Shared Contacts for Google Apps. The drawback here is, that this does not work for generic @gmail.com addresses.

Is there any other way (android app, software for Windows/Ubuntu, own contact server, ...) to sync common contacts in a way, that the contacts are present both on android devices and through the normal google webpages?

Lost Device = WiFi Passwords and Backup Data Stored Permanently on Google
Various sites like BGR have written articles on How to remove data from Google's backup and restore cloud.

But it's not possible once you've lost access to the device.  Hence your data will remain with Google FOREVER.

It looks like Android's Backup and Restore option makes it impossible to delete data stored on once the user no longer has access to the device.

According to the Answer in:

Google Backup: Multiple devices using the same account

Backups are stored in sets:

Example:
[Device serial][ Google Email] :
[3f0e5c90a412cca7] [ sampleemail@gmail.com]

and "You can't make a device start writing into a different set, nor can you wipe a whole set."

Since this is the case, once you lose access to your device, even with your email logged in from a different device, since you no longer have access to the device with the right serial, you no longer have the ability to delete the set from the Backup & Restore menu.

I checked to see if unchecking the "Back up my data" from one device would also uncheck the option across all devices using the same account for backup.

Apparently, this option in the other devices remained checked suggesting that their backup sets remained intact and continue to backup.

Is there a way to delete the backup data set once the device is inaccessible to the user?

How to make Android GMail app to show my picture next to my email messages?
I have a user profile picture selected for my own Google profile. This picture is visible in my GMail settings and works fine with web versions of GMail:

This profile picture shows successfully next to all my email messages on GMail web site, i.e. when I open my GMail account through desktop web browser (Chrome).

This profile picture also shows successfully when I open mobile version of GMail web site using mobile Chrome on my Nexus 5.

However, when I use the stock Android GMail app to read my emails on Nexus 5, my profile picture refuses to show. Profile pictures of other people show successfully next to their message titles, but my messages are displayed with the "default" profile icon - a large "A" in a square. Meanwhile, GMail app correctly recognizes these messages as posted by me: it explicitly says "me" in place of sender's name.

So, is there some sort of trick to make GMail app behave consistently with GMail web site in that regard, i.e. make it display my profile picture next to me messages in GMail?

Remotely control an Android tablet from a Mac or Windows machine?
Does anyone administer any Android devices as kiosks which you need to be able to monitor remotely?

I've been looking for something like TeamViewer for Android. I found there's a Support version which should allow people to connect to the Android device but I am unsure if you can fully control it? i.e load up certain apps, change app settings etc.?

I also found Bomgar and AirDroid or something similar.

Ideally, I need to know the status of the device (online or offline) and be able to diagnose any problems (or update the settings and apps). We already use SureFox Kiosk Web Browser which works OK (although it's not as responsive as just running the Chrome app)

Definitive Way(s) Of Knowing That One Has Bought The Revised Model Of The Nexus 5?
After complaints by many about the build quality of the Nexus 5, Google has apparently made certain hardware changes and released a revised version of its latest flagship handset in the last couple of days.

How can one ensure that they have the latest model of the Nexus 5 (or is it a given or matter of trust, that the Google Play Store and retailers will supply the latest). ?


问:
HTC reverse tethering 4.1
with Android 4.0 everything was fine, but after upgrading to 4.1 I can no longer activate reverse tethering successfuly.

```<code>Phone: HTC Desire X with 4.1 upgrade
Root: no and don't want to
PC: Windows 7 x64
AV: ESET Nod32 v4
FW: Comodo v6, currently uninstalled
</code>```

Symptom:

changing USB connection mode to "Reverse tethering" makes it attempt to connect and after a minute it displays dialog like (translated) 'Connecting to PC failed: either there is not HTC Sync installed in the newest version* or other device is already using  reverse tethering on your computer**.'

* not true, just installed newest

** no other device is connected

Installed - newest versions:

HTC BMP USB Driver

HTC Driver Installer

HTC Sync Manager (recognizes phone, backup works)

HTC Sync (just in case, HTC SM/drivers should suffice)

Additionally tried Google USB Driver (via Android SDK)

(plus ones like RNDIS etc. are as well)

Tried & notes:

with 4.0 everything worked flawlessly, even with these AV&FW active, without installing Sync etc.

attempts with AV and FW disabled, FW uninstalled at a point

HTC Sync Manager recognizes phone, backup works

MTP file transfer works

HTC Sync does NOT recognize phone (possibly important) (USB Debug has no effect either on/off)

HTC Sync offers update, after running its install it says there's already a newer one in PC

Windows driver install dialog after plugging in was all green (one day at least, that is, ofter there are fails: "device disconnected")

USB debugging either on/off no effect

Restarting neither phone nor PC has effect

Completely uninstalled and reinstalled all Android drivers and HTC software

In Windows Device Manager there are both My HTC and HTC Desire X, both report drivers up to date

Tried googling, two other forums, HTC support is not responding to my question.

What can I do to be able to reverse tether again?

Thank you!

This is probably a borderline question with superuser (possibly a PC's software issue), not sure which would be better, posted here.

Tasker: Voice response to phone calls
I was wondering whether it would be possible to use Tasker to answer a phone call and then say something to the caller (either through TTS or sound file) and then hang up? Would something like that be possible? I was thinking about making a task which will tell people to call me later because I'm busy now etc.

If it is could you outline how to make it?

Thanks!

问:
adb restore not working for shared
I have a Nexus 4 with Android 4.4.1 … I've read that we could root it without wiping the data …  well didn't work for me!

I wasn't scared, because I made a full backup using:

```<code>adb backup -apk -shared -all --nosystem
</code>```

Two things I forgot

SMS are not restored

Google Authenticator data are not restored (the
same week I switch all my accounts to two-step auth, like MtGOX …)

However, the problem is this :

Almost everything is restored, except the Pictures ..

Here is a part of the logs from log cat during the restore process

```<code> adb shell logcat

I/BackupManagerService(  605): File in shared storage: 0/DCIM/Camera/IMG_20130731_170638.jpg
D/BackupManagerService(  605): [discarding file content]
I/BackupManagerService(  605): File in shared storage: 0/DCIM/Camera/IMG_20130731_170235.jpg
D/BackupManagerService(  605): [discarding file content]
I/BackupManagerService(  605): File in shared storage: 0/DCIM/Camera/IMG_20130731_170116.jpg
D/BackupManagerService(  605): [discarding file content]
I/BackupManagerService(  605): File in shared storage: 0/DCIM/Camera/IMG_20130731_170110.jpg
</code>```

My question is, how to restore the pictures ?
There is no "adb restore -shared" option ..

In addition, it seem that all the android backup extractor solutions abe, perl, and the last version Titanium Pro, are not able to open encrypted android 4.4 backups …

Any ideas ?

UPDATE

Got a reply from Android Backup Developer (abe.jar) and this change + recompilation fixed the problem of extracting the backup. But this is not answering my initial question, why the photos are not restored using adb restore.

Full discussion here: https://github.com/nelenkov/android-backup-extractor/issues/7

This is the result of the change described here:
  http://android-developers.blogspot.jp/2013/12/changes-to-secretkeyfactory-api-in.html

and can be probably treated as an Android bug, because restring
  backups made with 4.3 will most likely fail on 4.4. File one at
  b.android.com if you can confirm this.

The fix is to replace
  PBEParametersGenerator.PKCS5PasswordToBytes(pwArray) in
  AndroidBackup.java:413 with
  PBEParametersGenerator.PKCS5PasswordToUTF8Bytes(pwArray). There
  probably needs to be some flag to switch behaviour for 4.4 and prior
  versions.

问:
HTC Desire C performing poorly
After using my HTC Desire C for a few days, it begins to show noticeable amounts of lag. For example, if I click on a menu, or open the dialer, or start to type message, it will take more than 6 seconds to open. Even when closing an app, it can take several seconds to complete.

How can I resolve this? Do I need to take it to a service center?

How can I specify a radius for Kitkat Dialer business search?
I like the business search in the Kitkat dialer, but it seems to have an odd concept of "nearby".  It will often give me results in different regions of the country, and if it can't find any, it will show me results in nearby countries.

Is there any way to limit the radius of the business search to be only within a certain radius?
