How can I root my Samsung Dart (SGH-T499)?
I've seen several sites using SuperOneClick, but can't seem to find a legitimate download link to it. (The original site, shortfuse.org was down).

I then saw TowelRoot, but it tripped Norton, saying it was a Trojan.

I also looked at iRoot, which also tried to trick me into downloading a virus.

I thought the gurus here might have some advice (or even just a SuperOneClick executable) to help me out.

How do I root my device?

Thanks!

PS I already looked at the one-root-question-per-device thread -- my device wasn't there.

PPS Possible relevant information -- It is speculated that this phone is a rebranding of the Galaxy Mini for T-Mobile, however it has capacitative buttons instead of the galaxy mini's tactile buttons. (I don't know if this helps)

PPPS The original SuperOneClick thread on XDA-Developers

PPPPS I also checked KingoApp -- no dice


问:
TouchWiz Air View no longer expanding / "exploding" home screen folders
The TouchWiz Air View feature on my Samsung Galaxy S4 used to provide a very cool feedback feature where holding a finger over a home screen folder without actually touching it would cause the folder icon to expand / "explode" and show a clearer picture of everything that is in the folder before actually opening it.

This is no longer working, and I cannot figure out why.  (It is not critical by any means, but it is annoying me that I cannot figure it out.)  How can I and the other users impacted by this (below) fix this?

Since I can't get it working again, I can't post my own picture to better demonstrate what is expected - but the forum thread at http://forum.xda-developers.com/showthread.php?t=2730260 ("[Q] Air view for folders in GS4 I9505") describes my exact same issue and includes several screenshots - though it is also unsolved.

Another reference to the same issue also exists at http://forum.xda-developers.com/showthread.php?t=2601067&page=63 ("KitKat 4.4 thread", buried in 227 pages).

"Air view" and all of its options are ON under the "My device" settings, and working elsewhere as advertised in the other applications.  (I even tried turning it off and back on.)  It is only the home screen folders that are no longer working.  I've tried rebooting.  I even used the "Force stop", "Clear cache", and "Clear data" options from the Application Manager for "TouchWiz home" (Version 4.4.4-I337UCUFNJ4) - and while this caused everything else on the home screen to reset to defaults (requiring me to re-place all my icons and widgets), it did nothing to resolve the issue.

I have not applied any device / firmware updates since this stopped working - though I'm uncertain if anything came through Google Play automatic updates that would have caused this (I haven't installed new anything recently).  There was a "Samsung Galaxy" update on 2014-12-19, and a "Samsung account" update on 2014-12-29...

Transfer android speaker output to windows pc over wifi
I Google for it but didn't find any solution: How to transfer/stream android sound output to pc?

I want to transfer all sound that android speaker plays, that includes app sound, games sound. I know about different music streaming apps like vlc app. But I want to transfer all sound not just song or video sound.

As I want to use it from a "far end", it must work wirelessly. Cable-bound solutions don't work for this case.

Connecting to a network that blocks non-computer devices with Galaxy S4
I would like to connect my Galaxy S4 to my school's WiFi network in order to cut down on expensive data usage. The problem is that some mobile devices (including my phone) can't connect, so I can't access the internet. I have the same problem at my house, where every 24 hours anything that isn't a computer gets kicked off and I need to reset the router. I am trying to find a way to fix this with all networks that have this issue (from my phone, as I can't modify the servers at my school). Since my phone is rooted, I can edit system files, so if I could modify my phone so that the signals sent to the network I am trying to connect to appear to be coming from a computer, I could be able to connect. Are there system files that I could modify to achieve this, or is it more hardwired into my phone? Note: I would only like to modify my phone's files, so that it is detected as a computer and not a phone. Mobile features may need to be disabled for this, so that it can technically be considered as a computer by the network.</p>

How to force software update on Android 2.3.4 model GT-S5830D Galaxy Ace
According to what I've read on line, it should be Setting -> About Phone -> Software Update, but in the About Phone section I don't have that option. Just Status, Battery use, Legal information, System tutorial, Model number, Android version, Baseband version, Kernel version, and Build number.

I also tried what lifehacker recommended, which was to

Go to Settings > Apps (or Applications) and select show All. Then find Google Services Framework and click the Clear Data button. Then click the Force Stop button.

or

dial ##checkin## (using the numbers on the dial pad for the letters)

But neither of these worked. Any suggestions on how to update the software, or clarification on whether or not I can at all?

Can't backup anymore Facebook & WhatsApp with adb

```<code>adb backup -noapk com.facebook.katana

and

Now, it seem it can't backup it when I run it. The backup procedure starts, but no good backup.ab file is created.

Does someone noticed this ?

Maybe they changed in the Android manifest:

Can I disable GPS?
Is there a way to completely switch off GPS or deny apps access to it?

Even though all three checkboxes in Settings -> More -> Location Services are unchecked and the button in the notification drawer is off, apps are still able to determine my location using GPS.

Disabling the Access to my location checkbox is not completely without effect, it does prevent Google Maps from showing my location. I noticed that in this demo application the "fused" location stops working but the "GPS" location still works. I further noticed that in GrabTaxi, a taxi hailing app, the map is disabled, but it is still able to search for "nearby places" (with much better accuracy than GeoIP).

How to schedule power on & off on a tablet?
I have an Asus TF303CL with KitKat.
I'd like to use it as my alarm clock, but it seems that the alarm cannot sound if the tablet is turned off during the night.

On my previous android smartphone (a chinese phone with gingerbread) I could simply go to settings and set the time at which the phone would turn off and the time at which the phone would turn on in the morning, so my phone was completely turned off during the night (it was not in airplane mode, it was turned off), turned on 5 minutes before the alarm and the alarm could sound.

How can I achieve the same effect with this tablet?
I've already checked the settings but I cannot find any entry similar to what I had on the old phone.

I know it's possible, since I've been able to do that for 2 years with a basic chinese smartphone; surely this brand new tablet can do everything that old phone could do. Maybe rooting the device is required for such a functionality?

问:
Lost my phone. Can I still locate it?
So I lost my phone a few days ago. Either somebody found it, or it is somewhere in the snow, soaked with water.

It's a Nexus 4 running CM12 nightly with GPS completely turned off. Google's Android Device Manager shows last online time to be January 10th, which is the day I lost the phone.
It says "Location unavailable" and nothing more. AFAIK, it should show that my GPS is turned off, or that I disabled google location reporting, but it shows none of it. Does this mean my device is turned off -or- wiped?
Can I somehow check the exact last online time (hh:mm) ?

I don't have any tracking apps installed.
Is it possible to locate it by using the IMEI?

A hidden exchange account
Yesterday my Nexus 7 (first gen) upgraded OTA from Android 4.x to 5.0.2 (Lollipop).

After the upgrade completed I opened the Gmail app and it now shows both my normal Google account and my business email account (Microsoft Hosted Exchange).

Yet for my Exchange account I only see the folders in the Gmail app, no messages and no calendar entries.
When I try to delete the account it is simply 'not there' in the list of accounts (under settings -> Personal -> Accounts).
Trying to add the account with the same email address gives the error "Duplicate account".

Perhaps relevant: The company I work for has some policy settings requiring a PIN on the lock screen.

I did find this thread but I'm not willing to root my device just to remove an account.

Modify boot.img of Moto G 2014 ROM
Starting from the Titan Prime ROM I would like to make some modifications to the boot.img. But if I try to unpack and repack the boot.img the phone jumps immediately into the bootloader after the start and says 'Fastboot Reason: Fall-through from normal boot mode'.

I hoped you could have a look at my workflow and tell me what I am doing wrong:

First I take your Rom and unzip it:

```<code>$ unzip TitanPrimeROMv1.0.2-XT1068-69.zip -d Titan
$ cd Titan
</code>```

Here is what the boot_info tells me:

```<code>$ boot_info boot.img
PAGE SIZE: 2048
BASE ADDRESS: 0x00000000
RAMDISK ADDRESS: 0x01000000

</code>```

Then I unpack the boot image:

```<code>$ unpack boot.img
Boot = boot.img

This image is built using standard mkbootimg

All done.
---------------
To recompile this image, use:
$ mkbootimg --kernel zImage --ramdisk initramfs.cpio.gz --base 0x0 --cmdline 'console=ttyHSL0,115200,n8 androidboot.console=ttyHSL0 androidboot.hardware=qcom user_debug=31 msm_rtb.filter=0x37 vmalloc=400M utags.blkdev=/dev/block/platform/msm_sdcc.1/by-name/utags' -o new_boot.img
---------------
2974 blocks
</code>```

Now I make some minor modification to the boot image like adding a file:

```<code>$ touch boot/ramdisk/hello_ramdisk
</code>```

Then I try to rebuild the ramdisk:

```<code>$ mkbootimg --kernel boot/zImage --ramdisk boot/new-ramdisk.cpio.gz --base 0x0 --cmdline 'console=ttyHSL0,115200,n8 androidboot.console=ttyHSL0 androidboot.hardware=qcom user_debug=31 msm_rtb.filter=0x37 vmalloc=400M utags.blkdev=/dev/block/platform/msm_sdcc.1/by-name/utags' -o boot.img
</code>```

I remove the boot folder, zip it and sign it:

```<code>$ mv boot ../
$ zip -r myrom.zip
$ java -classpath /opt/android-sdk/tools/sign/testsign.jar testsign myrom.zip myrom-signed.zip
</code>```

Then I place the file on the sdcard and try to install it via TWRP ‘Install’.

Can an antivirus really stop the broadAnywhere threat?
I had a look at the diff where the broadAnywhere threat is fixed, and it's basically just mPendingIntent = PendingIntent.getBroadcast(this, 0, new Intent(), 0); replaced with:

Intent identityIntent = new Intent(); identityIntent.setComponent(new
  ComponentName(SHOULD_NOT_RESOLVE, SHOULD_NOT_RESOLVE));
  identityIntent.setAction(SHOULD_NOT_RESOLVE);
  identityIntent.addCategory(SHOULD_NOT_RESOLVE); mPendingIntent =
  PendingIntent.getBroadcast(this, 0, identityIntent, 0);

I installed an antivirus on my mobile, and it said it is now defending my mobile against the broadAnywhere threat.

But since applications are sandboxed in Android and the identityIntent is going to be passed from one application to another, how on earth is an antivirus going to be able to detect what identityIntent is being passed between applications? Will an antivirus really be able to defend/protect a mobile phone from the broadAnywhere threat?

Google-cast to Android TV emulator
I was wondering if I can use the Android TV emulator (available from Android SDK) as a Chromecast emulator.

Android TV devices (like the Nexus Player) are Google Cast targets. I was assuming that the Android TV emulator is Google Cast enabled, but no app can find it on the network (even Chrome on the host that runs the emulator).

So either it's not enabled in the Android TV emulator, or I have to set up some king of port forwarding between the host and the emulator.

Which is it?

Delay on notifications from Facebook and Skype app on Lollipop
I use a Google Nexus 5 with Android Lollipop, the latest version. I use both Facebook messenger, Skype, and Whatsapp as message services. All three of those often have a delay (up to 30 minutes sometimes!) in giving me a notification that I got a new message.

Is there any way to fix this? It is very annoying.

how to give airdroid root permissions on kitkat?
i have a rooted S4 Mini on kitkat 4.4.2

now they have changed the permission so normal applications cannot write expect a given location on the external sd card. (which is not bad as security).

but now i cant use airdroid to upload files to my mobile.

so instead of allowing all applications to write on the external sd card.

i want to give airdroid root so it can write on the external sd card in any location while the  other applications are controlled by the new rule.

Is there a way to sync tasker profiles?
I use tasker on all of my android devices.  That includes my work and personal phone and tablet. They all pretty much run the exact same jobs but all I can find is some really rudimentary way of exporting a file to a very specific location.  it's pretty horrible.

Is there a way to sync changes between devices? Possibles add logic to profiles to just let profiles act if they are on specific devices.

Read information from old Kies3 call log backup files
I have discovered that my Samsung Galaxy S3 phone has a limit in the number of items retained in the call log, after which the oldest calls are deleted. Having previously suspected that this could be the case, I have periodically taken backups of the phone with Samsung's own backup/restore program, and have the backups on my Windows computer's hard drive.

Today I needed to check the time and date of a call I made almost a year ago, and saw the log in the phone didn't go that far back. I then started Kies3 on the computer, expecting some support to read the call log file (stored as Calllog.scl) among all the other stuff backed up. This was however overoptimistic - it appears the only thing Kies3 can do is restore the data back to the phone - no way to read it on the computer. Years ago I could read the call logs from my old Sony Ericsson "unsmart" phone, but Samsung seems totally unimaginative in anticipating a user's needs.

The format of the Calllog.scl file seems to be random data. I have had no success with trying to uncompress it, or to find any program that can read it.

Of course I could try to restore the old backup to my phone, but I am afraid the result could be a mess, due to the limited length of the log.

It also seems ridiculous that the log length is so limited considering that modern phones have GBs of storage. At least there could be a setting for the size.

I would be extremely thankful for any suggestions on how to extract information from the backup without restoring it to the phone.

Edit: I seems no one knows how to view the logs, which is not surprising, as I had googled extensively before posting this query. So now my strategy is to use a backup app (one simple and good one seems to be "Call Logs Backup & Restore" by Ritesh Sahu, https://play.google.com/store/apps/details?id=com.riteshsahu.CallLogBackupRestore). It produces human-readable xml files (even with style sheet to provide pretty display in a web browser).

My strategy is:

1. use the app to back up my present call log to an external file

2. restore the old Kies backup to the phone

3. use the app again to back up the old calls to a second external file

4. use the app to restore the latest calls (from step 1) to the phone

Need Help Unbricking Samsung S3 (GT-i9300)
below is a full and detailed account of what I have tried so far and where I think may be problems. I need someone with experience/in-depth knowledge of these sort of issues to give me a hand.

Okay so yesterday I had left my phone, a bit over 2 year old Samsung Galaxy S3 (GT-i9300) running M12 Snapshot of CyanogenMod11, all on it's own for around an hour and a half and when I got back to it it was stuck in bootloop at the "Samsung Galaxy SIII" screen. I successfully booted into recovery (ClockwrockMod Recovery v6.0.4.6) but get the error:

```<code>E:Can't mount /cache/recovery/command
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't mount /cache/recovery/last_log
E:Can't open /cache/recovery/last_log
E:Can't mount /cache/recovery/last_install
E:Can't open /cache/recovery/last_install
</code>```

Similarly when I move into mounts and storage and try and mount anything but storage/sdcard1 I get the message (using /data for example) Error mounting /data!.

Research lead me to believe that my best chance at recovering my Recovery, and from there Android itself was to re-flash CWM. As I wasn't able to get to Android, I tried to reach the bootloader but was only able to reach the Download mode for use by Odin/Heimdall.

I connected my device to my computer (Ubuntu 14.04) and ran Heimdall. Detect picks up the device and I can typically get the PIT, however when I try and flash recovery I get the below:

```<code>jake@jake-Aspire-5750:~/Downloads$ sudo heimdall flash --RECOVERY recovery.img --verbose --stdout-errors

问:
Extract drivers from ROM directly?
My girlfriend recently bought a Samsung Galaxy S5 which, after paying over 500 bucks for it, turned out to be a counterfeit s5.

Obviously the scammer didn't get back to us and as much as this is a good lesson to learn (don't be cheap and rely on Kijiji!), we want to make the most out of the phone as well. As such I am hoping to port one of the custom OS on it as the OS that came with the machine is pretty old (Android 4.2 I believe).

The problem is all the hardware signatures were obviously obscured and there is no way (at least I am aware of) to know the exact hardware pieces. My only hope is to somehow being able to extract the drivers out of the existing ROM and see where I can go.

Is there any way I can do that? If not, is there anyway you would recommend to make compiling of custom ROM possible without knowing the exact configuration of the phone (other than having a original factory ROM on hand and obviously the physical unit as well)?

问:
Apps on SD Card taking up internal storage (
My phone has been claiming the impossible for a while (see screenshot). Namely, it claims that more internal memory is being used than is available, and hence it is rather difficult for me to download new apps.

I believe that some apps that are located on the SD card are falsely being seen by my phone as living on the phone's memory, and it's somehow adding those numbers to the total amount of storage taken up.

If I go into my podcast app, for example, it says it's taking up about a gigabyte of internal storage even though a) that's not possible, b) it's all on the memory card when I go look in the file manager, and c) DiskUsage app shows this memory as being on the memory card, too.

DiskUsage app shows my internal memory as being just less than full, which I can deal with because I can delete a few things; I don't want to have to delete my podcast app's data again, though (it takes forever to get it set up again) every time I want to download a new app.

I tried dialing code #99009# and get an "unrecognized code" error message. My phone's also not rooted and I'm not going there :-/ I'm not that into tech and I think I would just end up wrecking everything.

Any specific advice would be awesome!

Thanks so much!

Hangouts keyboard not showing (Nexus 7 2013 Android lollipop)
I have a Nexus 7 2013 and recently upgraded to Lollipop. I'm having problems with hangouts making it unusable.

When I open a conversation in Hangouts, the keyboard is never available. The text bar at the bottom stays grey (same colour as app background) and never becomes tappable to allow the keyboard to show.

I tried last night clearing the cache on the app and this worked briefly but since re-starting the tablet the problem is back.

This is a huge problem as it is meaning I cant use Hangouts (the main messaging app I use with friends and family) on my device and instead have to hunt for my phone each time.

Does anyone have any experience of this or sensible suggestions?

Thanks,

问:
Android L GMail app remove default account
I currently have Android L (5.0.1) installed on my Nexus 5. I thought my phone had a problem with syncing but it turns out that my GMail app keeps trying to sync my email address with GMail. I have an @live.nl email and this email is the same email as I use for my Google account.

So, the GMail app tries to get my @live.nl email from GMail's servers, but since this is a @live.nl email and not GMail, it keeps saying "trying to sync". I have no way of deleting this account without deleting my entire Google account from my device, something I do not want because it stores all my data. I can also not add my @live.nl email because it keeps saying it's a duplicate. It seems like I'm stuck in a loophole.

Does anyone know if there's a way to make the GMail app not try to retrieve my email from the GMail servers? I already unticked "Sync with GMail", but it keeps trying anyway.

Share USB Printer from Android Device to Network
Is there any form of printer sharing FROM an Android device (In my case, a generic AMLogic Android Box, 4.2 or 4.4, full sized host USB ports) to a network? Specific method doesn't matter, CUPS, IPP, Jetdirect, would all work, even something like a drop box service where I send a pdf and it automatically prints.

Searching around, I have not seen anything for this direction, everyone wants to print from Android to an existing network printer, but I would like my Android box to be the server. It seems every other kind of server has been implemented, network shares, screencasting/vnc, keyboard and remote control, etc, but not print serving.

If running it as an underlying linux service is required, what is the best method for this? My searching comes up short.

Fastboot Commands Via Update.zip To Unlock Pattern Lock on Asus Transformer FT201
I purchased an Asus Transformer Prime TF201 a couple years ago.  I added a pattern lock on this tablet so our kids would not use it all the time.  One of them decied to try the pattern too many times.  Now, it is stuck at the Too Many Pattern Attempts screen.  This has happened before and I was able to reset it by using my Google Account (wifi was on).  However, this time, I had to charge the device first before turning it on and discovered that it was in lock mode again!  I tried to get past the lock screen using Google credentials, but no go.

I am assuming the wifi turns off when the battery is drained.  And because wifi is off, it cannot authenticate using my Google Account.  I know my Google credentials and I also know the pattern, but I cannot use them!  I have pics and videos of our children that I do not want to loose.

I have been doing research for a few days now and it seems that if USB debugging was enabled, I could just run some adb commands (using the adb executable) and reset it to the point where I could try the pattern again.  But USB debugging is NOT enabled!

I am not sure this device is rooted??  I know that when I was using it, I was able to see all the directories (using the AndSMB app, but not sure if i was able to write to all dirs). It is a stock device with no mods.  It was upgraded to 4.1.1 (it was an update supplied from Asus).

Some good news: I am able to start the device in fastboot mode and it is detectable using the fastboot command tool (via Windows or Linux) while connected to supplied usb cable.

There is a tool called Android Script Creator (by Octanium) that can create an update zip file from custom commands.  I was able to create a zip file named Update.zip with the following commands..

```<code>ui_print("attempting to start wifi..");
run_program("svc", "wifi", "enable");
ui_print("done");
</code>```

Questions

Am I on the right track?

Will the script I wrote work?

How do I run this update file I created?

Does the Update.zip file need to be flashed (or copied - what's the difference?) to an external SD card?

Can I use the fastboot tool to place this zip file on the internal memory and have it run?

Additional Info.. i found some links that may help.. but not sure what to do..

This link points to an article that describes how to use an update zip file, but it says to flash the CWM.  Is the CWM necessary to run an Update.zip file?

Here maps isn't working: "could not download initial data"
I've tried to install Here Maps on my phone (a Samsung Galaxy Ace Plus) and I've not been able to make it work.

The maps are not displayed at all, all I can see is a blank screen. If I try to zoom out, I will eventually see the whole globe, but just as a blue sphere, without any feature.

The strange thing is that if I try to search for a place I can get the pinpoint indicator, supposedly at the right coordinates, but, again, no map is displayed. It seems that some kind of data is accessible but the graphical part isn't working.

I have also tried to download the maps for offline usage, but when I try to do it all I get is the message "could not download initial data", and I'm even unable to see a list of the maps available for download. That same thing happen when I try to download voices, I get the same error and nothing is downloaded or even displayed.

How can I get Skype to run on a MD700 tablet?
My uncle bought a cheap MD700 tablet (running Android 4.1.2) and strongly desired to use Skype on it, but for some reason the application didn't recognize microphone input. All it could be heard on the other end was a constant, static buzz.

I started trying older app versions until I found one that worked, and he stuck with that one until it was finally phased out, months later. Now, all accepted versions exhibit the same buggy behaviour.

The integrated microphone and the microphone jack were ruled out as culprits through testing. Other apps record audio flawlessly, and the issue persists even when using headphones. I believe the evidence points to a Skype bug or compatibility problem. A restart to factory settings didn't help. There are no ROMs available for this tablet, so updating Android itself is a no-go.

Running out of options, I connected the device to a Linux station and ran a logcat command during a test call. I considered some dalvikvm, nativecrypto and networkstats entries to contain no diagnostic value, so I filtered them out.

The result can be found here.

While applying some amateurish debugging skills, the following entries catched my eye:

W/AudioStreamInHandler( 4436): read but no streamin

D/AudioYusuHardware( 4436): Audio_Match_Force_device Force_config=0x1

D/AudioSPELayer( 4436): 0

Alas, they do not give that much of a hint for the non-Android developer.

Any ideas on how to proceed or what to test for?

Thank you all in advance.

How to increase wireless speed supported by Android TV BOX CS928?
i have recently purchased Android Tv Box CS928 from Chinese site http://www.aliexpress.com/item/CS928-Android-4-4-kitkat-Rk3288-A17-quad-core-2GB-16GB-2-4-5-0Ghz-100M/1939723909.html

i bought this because it says

```<code>Network     2.4GHz/5GHz WiFi 802.11 b/g/n and 802.11 a/c. Support LAN 100M/1000M Base-T
</code>```

so i was under impression that (802.11 n and 802.11 a/c means 300 Mbps) this will be perfect fit for my home wireless network which is working at 300 Mbps using wireless router TP-Link 1043ND

but when i connected my Android Tv Box CS928 to wireless network in my home i can only get 65 Mbps highest speed at the Android Tv Box CS928 , i even tried placing the my TP-Link router next to Android TV box but it didn't increase the Wireless speed , it shows signal strength as 100% but the wireless speed is 65 Mbps.

So i have tried forcing my TP-LINK wireless router to transmit and work at only at 300 Mbps speed by setting

```<code>Channel:    1
Mode:   11n only
Channel Width:  40MHz
Max Tx Rate:    300Mbps
</code>```

but still the Android TV BOX connection status shows wireless speed as 65 Mbps

why is that ?

how can i increase the wireless transfer speed of Android TV box so i can watch HD movies streamed from my PC to Android TV Box?

问:
Android Download Manager does not properly resolve hostnames
I have had an issue for a while with a few of my Android tablets. Those tablets would consistently refuse to install or update software from Google Play.

I have spent days looking for a solution; I have had a number of different error codes over the period - all similar to Error 495 (there are pages and pages of "help" out on the web).

I obviously tried all the supposed fixes for the problem - wiping data, cache, uninstalling updates for Google Play, the lot. Nothing worked.

Yesterday I finally got adb to work with one of the tablets (that was a bit of an ordeal by itself) and it finally led me to figure out what was going on.

I was running Android Device Manager and keeping an eye on the log files on the device as I was trying to install upgrades. I found the process fails with the following error:

01-23 23:25:33.869: W/DownloadManager(7289): Aborting request for download 205: while trying to execute request: java.net.UnknownHostException: Unable to resolve host "r2---sn-ab5l6n7z.gvt1.com": No address associated with hostname

This would then - eventually - result in Google Play returning an Error 495 (which in and of itself is completely useless :))

Once I saw that log entry, I manually updated the DNS server address on the tablet to 8.8.8.8 - from the DNS server that is normally used on my network.

Mind that every other workstation/laptop in the house works fine with my "own" DNS server; as a matter of fact, every other function (such as browsing the web, checking email, etc.) all work perfectly fine as well.

I therefore have a suspicion that there is more to this story than just my DNS server - somehow Android DownloadManager doesn't like mine?

Does anybody have a similar experience?

Google Play doesn't recognize my Genymotion device
I run Android 4.4.4 in Genymotion. I installed the Google Apps, which include Google Play. I logged into my Google account, and I see in the Google Play application on my phone that I'm logged in.

Genymotion and video ads
I run Android 4.4.4 in Genymotion. I installed the Google Apps, which include Google Play. Through Google Play I installed the game Sky Force 2014.

Why can't I click on the button in the red rectangle area in the screenshot below?

This button is used to display some 30-second video ad, which gives me one additional spaceship.

Maybe the fact that the button is greyed out mean that for some reason video ads don't work in my  Genymotion virtual device? Any other ideas or solutions to try to fix it?

Everything works fine on my phone (Samsung Galaxy S5 (SM-G900A)).

nexus 7 (2013) adb connectivity issues Mac
The 5.0.2 OTA update soft-bricked my rooted but otherwise stock Nexus 7.  I tried several times to wipe/reset from recovery, but it kept boot-looping afterwards.  After a hundred tries or so was finally able to connect via adb to my Mac and sideload the update.  Booted up fine after the update but of course all my data is now gone.

Problem is that now I cannot seem to get any adb connection over usb so that I can re-root and restore my backups.  I am hoping this isn't a hardware problem as my device is a year-and-a-half old.  Maybe someone can confirm it's likely hardware related, or even better has a solution that I haven't tried yet.

Here is a list of everything I've tried to resolve the issue.

1) Cable/ports - I am using the stock asus USB cable that came with the tablet.  It powers the device just fine.  When I connect my Nexus 5 with the same cable, then adb works perfectly from my Mac (2009 MBP w/ USB 2.0, Yosemite 10.10.1).  I have tried another USB cable with the same result.  I have tried all 3 of the USB ports on my MBP with same result.  Running system_profiler SPUSBDataType from the Mac terminal doesn't show the N7 (but it does show the N5).

2) Windows - I don't have a Windows computer, but I do have Win7 running on VirtualBox.  I have the same connectivity issue there, the WugFresh NRT recognizes my N5 but not my N7.

3) Settings - I have disabled/re-enabled USB in Developer Options several times to no effect.  I also toggled the MTP/PTP connection options on and off (I keep them off as I transfer files using AirDroid in lieu of the crappy AFT).

4) adb - From Terminal Emulator running on my N7, I have killed and started the adb server several times.  I can't use adb tcpip (wifi) without the device being rooted.

At a complete loss here and really don't want to replace my N7.

Is it possible to upgrade the Galaxy Tab 10.1 (GT-P5113) from 4.2.2 to a higher Android version?
I have an unrooted Galaxy Tab 10.1 (GT-P5113) running Android 4.2.2

I want to upgrade the Android version there, however, I have no idea how.

Samsung Kies refuses to upgrade the firmware with the message "gt-p5113 does not support initialising".

Unzipping without an app?
This is a somewhat old phone running Android 2.3.6. My phone is not an English phone, so the below may not be exactly what an English phone would say.

I've downloaded a zip file to my phone that I want to unzip. When I click the file, the phone tells me no programs can complete that action. Which is true, as I don't have any apps that deal with .zip files. Except, I know the phone can do this without an app - I know this because it actually started to, and managed to unzip a few files before I hit the "back" button (on accident; I was trying to back out of something else when it popped the unzipping on me). I have those files in a directory next to the .zip file.

Battery draining faster after recharging on Galaxy S4 Mini
I'm struggling with my Samsung Galaxy S4 Mini. Actually the battery is very good and since I don't use my phone a lot, it lasts pretty much 2 days when I let it die and full recharge it.

The issue is, everytime I recharge it when the battery is not dead, the battery is draining very fast even though I don't use my phone.

How to mount an ext4 formatted external sdcard in stock Android 4.4.4?
I upgraded from the Note 1 with cyanogenmod 11 to the Note 4 (910C) with stock android (rooted). I want to use the ext4 formatted external sdcard, but Samsung does not added ext4 support for the extSdCard (WHY???????????), so it is not being recognized at boottime. Anyway, I managed to mount it, but I am only able to use it as root. Yes, the ooold permission problem.

I used this script for this:

```<code>REALMNT=/mnt/media_rw/extSdCard
mount -t ext4 -o rw,noatime /dev/block/mmcblk1p1 "$REALMNT"
sdcard "$REALMNT" /storage/extSdCard 1023 1023 &
</code>```

This script does mount the card, but with the wrong permissions. I also changed the permissions in /system/etc/permissions/platform.xml, no luck.

Some permissions I get after mounting the sdcard manually:

```<code># ls -la /storage (notice 1015 instead of 1028)
  ....
  drwxrwxr-x 13 0 1015 4096 Jan 29 02:52 extSdCard

mdev: applet not found when trying to populate /dev on android
I'm trying to install Debian on the Android 4.4 (modded with cyanogenmod) that's installed on my nexus 10 to one external sd card. I'm reading this tutorial :

http://whiteboard.ping.se/Android/Debian

I've attached the Leef microSD microUSB Connector with a 64GB sd card inside to the mini usb port of my nexus 10 as you can see here :

The tutorial talks about the The ASUS Transformer TF101 and the instructions are based on this tablet. Instead I have a tablet nexus 10,that's equipped with an internal sd card where I have installed android 4.4 + cyanogenmod. For this reason I need to know how to change some part of the tutorial to adapt it to my situation. Anyway on my desktop computer I have partitioned the sd card in this way :

```<code>Disk /dev/sdf: 64.0 GB, 64021856256 bytes
255 heads, 63 sectors/track, 7783 cylinders, total 125042688 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0004504c

   Device Boot      Start         End      Blocks   Id  System

/dev/sdf2        32768000   125042687    46137344   83  Linux
</code>```

according with the tutorial,these are the commands that I have issued right now from my desktop pc to the tablet using the ssh connection :

```<code>mount -o rw,remount / ;
mkdir /mnt/deb ;
mount -t ext4 /dev/block/sda2 /mnt/deb ;
mkdir /mnt/deb/proc ;
mkdir /mnt/deb/sys ;
mkdir /mnt/deb/dev ;

/system/xbin/busybox mount -t tmpfs none /mnt/deb/dev ;
/system/xbin/busybox mdev -s ;
mdev: applet not found
</code>```

and now I'm freezed here. I've tried to find a solution by myself with google but I haven't found the solution. This is what I have tried to do :

```<code>~ # echo $PATH
/sbin:/vendor/bin:/system/sbin:/system/bin:/system/xbin

~ # which busybox
/system/xbin/busybox

~ # find / -name mdev
/mdev

问:
Can apps completely take over sound I/O in calls?
I've done some searching but this is a pretty hard question for search engines. I need to know if an Android app itself can take full control of call sound I/O on calls to the PSTN.

I've found "background sound effects" apps e.g. to add traffic sounds to the background of a voice call, but I'm not sure this indicates what I'm interested in - the ability of an app to do ALL sound I/O on voice calls. And of course there are the call recorder apps which indicate that incoming voice call audio can be diverted and processed.

Examples where this would be useful:

realtime voice disguiser apps (shifts the pitch of your voice etc)

apps that detect when hold music is interrupted by a human so e.g. one can put the phone down and it will beep when a call center employee answers

apps which implement a DSP modem which can talk to a modem (or fax machine) on the PSTN, even if at low speeds like 4800-9600bps

The latter is my particular interest - being able to have an app which acts as a softmodem and can talk to modem-based devices on the PSTN. I'd imagine it might be technically possible given the CPU power of modern phones but I wonder if it's possible given Android's own capabilities.

Working inside VPN using an unrooted Android device (or Genymotion)
I am trying to use an unrooted Android device (or alternatively, a Genymotion emulator) to run an application that needs to be connected to a VPN. On my PC, I only need to connect via Cisco's AnyConnect, and to use a RSA token generator.

However, I'm finding it quite hard to have VPN access in my device. Here are all the approaches that I've followed.

Installing Cisco AnyConnect for Android didn't work for me, since this can't be done without a token. I can use the generator from my PC, but I don't have a similar software in the device.

StackOverflow's questions about the "Genymotion approach" don't have any answers, unfortunately. For example, this older question and this newer question.

Reverse tethering also didn't work. This seems to require a rooted device.

The last approach I tried was using a laptop as a hotspot, and then connecting to this newly created WiFi network. However, although the network was created, and the Internet connection was succesfully shared, I wasn't able to connect to AnyConnect from the laptop after setting up this network.

Any additional ideas on how to share this VPN access to the device will be highly appreciated. On a final note, the VPN I'm trying to connect to is a customer network, so unfortunately I'm not expecting too much help on they side.

Recover deleted app data
I'm having some trouble with an app, it is an app for a service provided by my local bank. Apparently for security purposes it is not on the Play Store and when you subscribe they send you an SMS with credentials and app download link.

I downloaded the app and used it. First time you launch it asks for credentials and activates your account, no login Activity, just the Activation Activity and then it goes straight to usual interface every time.

So I accidentally deleted the app data (meant to delete cache) and now every time I launch it I have to activate my account, which won't activate because it is already activated !!

I spoke to the bank customer service and they said I can only cancel subscription first before they send new credentials which is supposed to be done from within the app. So I'm stuck unless I can recover the app data. They are charging me for the service by the way.

I am using a rooted Galaxy Note 8.0, is there any way I can recover the data ? Preferably for free?

My workflow on my Nexus devices has been to keep a PGP-signed version of the stock recovery around on the device, flash a recovery to the recovery partition while the phone is still running (dd if=openrecovery.img of=/dev/block/.../recovery), boot into recovery, backup, flash away, then reboot. If everything is well, verify the signature on the stock recovery and flash it similarly to how we flashed the recovery.

This process makes sure that cold-boot attacks are impossible, unless I forget to reflash the stock recovery, which I haven't failed to do yet.

How does this process work with Samsung phones? I have a Samsung Galaxy S5 (G900T) with a custom recovery installed. I can easily get the stock recovery. However, how do I "lock" the bootloader, for lack of a better term? There's nothing I know of in Odin which would allow me to lock the device.

Is this possible with Samsung phones?

Android picture naming convention
I am using Samsung Galaxy S5 from T-Mobile.

I noticed that pictures are named as

YYYMMDD_ABCDEF.jpg

where the first part represents date and the last purt I suspect represents time in military format. This is very convenient but it would be more convenient if I could choose to name my files like

YYYY-MM-DD_ABCDED.jpg

automatically.

Does anyone know how to change default picture file naming convention in Samsung Galaxy S5 / Android ?

CyanogenMod browser displays only a white screen
I just installed CyanogenMod (11-M12) on my Galaxy S3 I9300. Now after some days, web browser only displays a white screen, not page content, not address bar, only a full screen white page (only taskbar on top).</p>

WiFi network in range, but could not be connected!
In my mobile phone (CyanogenMod 11-M12, Galaxy SIII I9300), in WiFi section my WiFi SSID is shown and under its name is Save, secured with WPA/WPA2. WiFi is ON. If I press SSID, a pop-up ask me to Cancel, Forget or Connect. and if I press Connect no connection is established!

I was connecting to this SSID without any problem before this. It seems that this problem occurred after installing "Google Apps" or after changing some privacy setting in Privacy Guard section. But I did not remember changing any system application's privacy settings, I just limited Google Apps privacy access.

Update 1:

I tried Factory Reset from recovery mode. It solved the problem, but after few hours of working with the device, the problem repeated. After that, Factory Reset did not solved the problem. I tried reinstalling CM from zip file. I installed CM11 zip file and did wipe (Cache, System, Internal Storage) partitions from recovery, but the problem persists. In the second try, I did wipe (Cache, System, Data, Internal Storage) partition and installed CM zip file after that. This solved the problem. But I am not sure if the problem will occur again or not?

Update 2:

The problem occurred after a while again, it seems that the problem occurs after installing some Google Apps!

What might cause my Sony Tablet S to run very slowly
My Sony Tablet S has developed a gross speed problem. For the last several months it has run exceedingly slowly most of the time.  Apps take 10's of seconds to start, taps to bring up menus take similar times, and more often than not I get a "Application is not responding" snag message to which I have to answer "Wait' to get the menu to drop down.  I sometimes get spontaneous reboots when opening an app.

I used a Task Manager called Free Advanced Task Manager which shows the CPU usage.It varies from 15% to 117%.  When It was indicating 117% there was no individual task with any appreciable CPU usage.

The tablet is not rooted, Android v 4.0.3 5a.  Some apps on SD card, card (32g) is about half filled.  Device memory has around 1G spare.  RAM usage is usually about 300/750 Mb.

My question is: what are the likely causes for this and how do I track down the offender?

Use speakers even if earplug plugged in?

My dailer works as it should, but as soon as you place the call, you hear nothing. However, the phone still is making a call to whom you dialed.

My phone won't turn on/charge and I need to get data off of it
My phone is about 5 months old and for some reason it completely stopped working the other day. When I plug it in, in order to charge nothing happens, and when I plug it into the computer no information comes up. I bought the phone from Amazon and they're letting me return it for a full refund and I just got a brand new samsung. I'm positive that I was backing up my phone the whole time I had it, but almost nothing has been retrieved when I tried to restore my old info on my new phone. Do any of you guys know anyway to get the data off my Samsung's memory without being able to use the screen or it registering when it's plugged into my laptop? If I need to go to the Samsung store and I can't handle this myself, please let me know, otherwise please give me an any info you can think of.

Also, the phone was set to backup, and absolutely nothing backed up the whole entire time. i am so confused and would just really appreciate some help.

unable to connect to my nexus 10 with android 4.4 and cyanogenmod with a remote desktop manager
Hello android users and developers.

I would like to give a developer temporary access to my tablet so he can help me solve a problem. On the tablet is running android 4.4 + cyanogen mod 11. I have installed the no-ip client for android and a tool called "airdroid" and I have also configured an ssh account.

I'm not able to connect to the tablet using the domain name (marietto2008.no-ip.org) that I have associated to the internal IP number (192.168.254.1). This is what happens when I try to ping the internal IP number and the domain name associated :

```<code>root@localhost:/home/marietto# ping 192.168.254.1

it hangs !

I can connect to the tablet using this address that I have received when I have installed airdroid :

also,I can connect remotely with the tablet using the ssh account at this address :

but not using the domain name :

Lenovo USB 3 to Ethernet adaptor not working on Nexus Player
I have a Nexus 5, a Nexus Player, a USB OTG cable, and a Lenovo USB 3 to Ethernet adapter.

If I plug the Ethernet adapter into my phone (using the OTG cable of course) it loads the cdc_ether driver and sets up the interface eth0 (I ran cat /proc/kmsg).

However, when I do the same on my Nexus Player, it doesn't do either (however the kernel still picks up that I plugged it in).

I don't know a huge amount about Linux kernel development, but both seem to have cdc_ether.c in their kernel sources. Any ideas?

I found on Root Explorer that the owner and group is set to root. I try to change to system but it does not change.

And the permissions is set to read and execute for the owner and group and other.
The write permissions is disabled to the owner and group and other.
I also try to change the permissions and unroot my phone but it does not work.

Wifi CA Certificates disappearing
I have an Xperia E3 running 4.4.2. My university's wifi network has a CA certificate to avoid having to re-enter credentials each time you connect. However, whenever I install this certificate (and select it for that network) it disappears after having been used once or twice, so I have to re-install it every few days. To clarify, when I go to "modify network" the CA certificate disappears from the drop-down menu, and it also disappears from my list of trusted credentials.

Is there a way to keep it permanently instead of having to re-install all the time?

Sony Xperia SP (C5303) + Cyanogen
I tried to follow article on http://wiki.cyanogenmod.org/w/Install_CM_for_huashan#Unlock_your_Xperia_SP

to flash Cyanogen on my Xperia SP.

I used flashtool to get into fastboot. I got unlock key from Sony page, I unlocked bootloader.

Then I followed step:

Extract boot.img from the zip to your computer, you will need this file for fastboot.

Put the phone into fastboot mode:
With the device powered down, hold Volume Up and connect the USB cable. The notification light should turn blue to indicate you are in fastboot mode.

Open a terminal on the PC and enter the following:
fastboot flash boot boot.img
fastboot reboot

After reboot I got black screen, no Led, but Device gets connected in Win as: Sony sa0108 ADB Interface Driver

However I cannot get adb running.
