How to limit data usage of individual apps?
There are many apps out there to limit data usage of entire system. Using Firewall, I can block an app from accessing Internet, too.

But, I don't want these. I want to limit data usage of individual apps. e.g. - AppX should be firewalled if it comsumes 1GB within a day or month etc.

How can I achieve this?

I am rooted on ICS. I have tried to use Tasker but without luck.

Google Play Store App error
I upgraded my Samsung Galaxy Note GT N7000 from Gingerbread to ICS. (Had used the software update option:

```<code>Settings → About Phone → Software Update → Update[check for updates]
</code>```

And thus the Google Play Store app also got updated to the version 3.8.17 which is compatible with ICS.

But the app on my phone plus the Play website apparently still have the old Android version. As a result apps which are now compatible with ICS (for example Adobe Photoshop Touch) are still:

Shown as incompatible on the website and

Not even displayed in the app on the phone.

I have already tried:

Clear cache and data of the app;

Uninstall all updates of the app;

Installed the app version 3.8.17 again via another source on the net but it did not help. So now I also, don’t have the original app provided by Samsung.

Question: How do I solve this? Is there someway I can download the app via Samsung without installing the whole of ICS again?

  SD card partitioning? why? how?

I am trying to partition my sd card on my Samsung Galaxy Ace because I want to extend my memory using the app link2sd but I have some problems doing it.

make a first fat32 partition of 3GB for the SD
make a second ext3 partition of 800MB to extend internal memory and use link2sd

Firefox Beta and Youtube - no play nice
I'm loving Firefox Beta.  My current only problem with it is that when it encounters a resource that needs to be opened with an app, it does not do that.  Instead, it gives me the non-useful error message "This link needs to be opened with an application."  Youtube is a clear example.  The android browser knows to open Youtube videos with the Youtube app, but there don't appear to be any kind of user agent settings in Firefox Beta?

I already tried removing defaults from both Firefox Beta and Browser.  Again, Browser properly interprets the default application for youtube anyway.

I also don't want flash; I don't want to play the videos in the browser but in the youtube app.

问:
Bluetooth HSP profile backward
I am deaf and use a cochlear implant and a hearing aid.

I have a device called a "microlink" which acts as a bluetooth 1.1 headset (amongst other things) and transmits audio received via BT to FM whence it is received by tiny FM receivers attached to my CI and HA.

This PHONAK Microlink device was expensive and works fine as a mobile phone headset (HSP profile), but when I had a NOKIA E series phone I could also play music from the phone's media player - which was fantastic!

Now, I have a Blackberry and a Nexus 7 and neither of them will send audio other than a phone call via the HSP profile, I assume they insist on A2DP for audio.

This is crippling to me, since I cannot now listen to music from either of my Blackberry or Nexus 7 without being wired up to it (or using a direct connection to the Microlink).

I cannot believe in this age of backward compatibility that there cannot be some way of sending media player output to (mono) bluetooth HSP as used to be the case.

Also, since the NEXUS 7 is not a phone - what the heck is the use of HSP on the device? (which shows in the profile list) - a nice port of Android, but why does it still think it's a phone!?

I came across an entry in some list some time ago (that I can't find now!) talking about being able to enter some secret AT string or something to a phone which caused it to redirect audio (from its speaker) to HSP bluetooth - does anyone know anything about this?

Prevent Trebuchet from showing up in Recent Apps?
Here's the setup I have for my phone right now:

I am running on a custom ROM that has Trebuchet for the home application.

The custom ROM is ICS-based.

I have somewhat successfully gotten Google Now (the Jelly Bean feature) to work on my phone.

I decided to use Home2 Shortcut to map double-clicking on my home button to launch Google Now's voice input.

The above setup works fine aside from a single caveat. When I view the Recent Apps menu while inside another application, I can see Trebuchet on the list. This is not the behavior I was looking for and from what I can tell, it is appearing on the Recent Apps because I've set Home2 Shortcut as my new home app (to handle the double-clicks) and then Home2 Shortcut opens Trebuchet as regular application.

So yeah, now I want to know how I can make Trebuchet not appear on Recent Apps. Is there some kind of manifest-editing that I can do to make Trebuchet act that way? If not, what other approaches can I try?

Nexus S after update to JB doesn't show callers name
I've installed the update to Jelly Bean on my Nexus S and when someone calls, it shows only the phone number of the contact (the contact was saved in the contant list) and not the name of the person.

When I updated to ICS some months ago, the phone number was there for few seconds (like 5 seconds or so) before the name actually appeared.

What's causing this and what can I do about it?

Something tells me that it has to do something with performance of the phone. On Ginger Bread it was all good. On ICS it took some time to show the name and now it doesn't show at all. The phone is incredibly slow and almost out of memory the whole time.

EDIT: When the call ends I can see in the history of calls that it shows the name of the contact.

Changing 3D Gallery with virtual device 2D Gallery
I have a ZTE Blade which reboots everytime I open the 3D Gallery.

I put it into my Blade /system/app, I changed permissions, restarted the phone and nothing. There is no new gallery inside the app drawer.

What am I doing wrong? The emulator is running Froyo.

I've tried different galleries from Google play but none suits me, specially due to Picasa integration.

I've tried different Gallery.apk from other forums with the same luck. I even tried to install them but it end with an "App is not installed" message.

问:
SD-EXT file system damaged in a few days
I'm running an cooked Android on my HD2 with the sd-ext partition trick to increase storage space.

I noticed that with more than just one ROM that file system gets corrupted in a very short time. In a few days of running the FS gets so corrupted that Android itself can't boot. I have to fsck from my Linux machine and get lots of lost files before turning the phone on again (and every time I lose something).

While the obvious answer (I actually haven't asked anything yet) may seem to "try another ROM", my question is: what could be causing this corruption of the file system as soon as I always turn off my phone the clean way?

Could it be some program running on top of Android? Unbelievable, Linux kernel handles file system internally. AFAIK, virtually no app can damage a file system if only operating with file read and write

Could it be the Android kernel?

Could it be the specific data2sd script that I install from recovery? I don't think so because what it does is to merely install an init script that runs once per boot and mounts the card.

I'm asking if anyone here had the same problem, and if and how he/she managed to fix it.

AT&T Galaxy SIII / Windows 7 64bit AMD/ Cannot mount USB drive

I and they have tried dozens of combinations of running Kies, Developer Debug Mode, pull the USB cord now, put it back in now... on and on. One guy had me yank the battery, "NOW!" I also called a magic phone number *#7284#, which is actually a backdoor into a settings menu. I have also tried following some suggestions here on android.stackexchange. All I want is for it to work like a USB memory stick. Plug it in, and there are my files in a Windows Explorer folder. Dream on,right?

The USB port on the PC worked for a Galaxy SII before the phone quit working completely. The cable is fine. But I tried other USB ports and other cables anyway.

Question 1. Can this be right? On a 64 bit Windows 7 OS? Is it supposed to be in system32?

Question 2. Does the fact that the drivers without MTP in the name load okay indicate that the hardware on the phone is working?

Question 3. Anyone know of a backdoor that will allow me to mount at least the add-on SD card like a plain ol' external drive? I'll bet there is one.

UPDATE: I removed all SAMSUNG drivers from my PC. Reinstalled latest and greatest (1.5.6.0, which showed 1.5 million downloads). I did a factory reset on the phone. Rebooted everything. Tried again. No joy. I let Windows install drivers from the net. Still no joy.

Google Voice free calls on a Tablet
I recently bought a small tablet - a Samsung Galaxy Player. I've been using Google Voice to text all my friends for free. However, I would like to start being able to call my friends as well, and have them be able to call me.

I see on the Play Store that there is an app called GrooVe IP that allows me to do such a thing, but I would prefer not to pay $5 for this app. My goal, then, is to find a free alternative that works just as well.

I've checked out SipDroid - but I can't figure out how to use the dialer. I'm not entirely sure there is one. You see, there are billions of tutorials on the internet to help set up SipDroid on a "real" phone, but I only have a tablet with no calling capabilities, so I can't use the built in dialer because there isn't one. One thing I could do here is to find a third party dialer that works with SipDroid.

I have also looked at 3CX for Android, but I can't figure that out either. It assumes you have a VoIP Provider, which I don't, unless I can use the Google, which would be very nice.

So, in this case I have three questions:

Is there a free alternative to GrooVe IP that works just as well?

Is there a third party dialer that works with SipDroid?

How do you set up 3CX with Google Voice, if possible?

I only need one of these three questions answered, not all three.

  Does constant charging harm my Android cellphone?

Indeed, this is a duplicate of: Does constant charging harm my Android cellphone?

Just for the record -- let's say I leave phone charging for 8 hours, it will charge to 100% in 2 hours, so for the last 6 hours would be over charging.

I used dumb phones (Nokias) this way for years, and nothing bad happened. I did it few times with Samsung Galaxy Ace 2, but after I heard some rumor it could damage the phone I try to disconnect the phone once it reaches 100%. Yesterday after 5 minutes of over charging the battery dropped from 100% to 77% in few hours in pure stand-by mode (no net, no gps, no calls, nothing, just waiting for action).

No wonder I am now afraid of the battery life and also interested in getting facts. So far I found only just statements -- in case of iPhone "overcharging means no harm", in case of Android "oh God, no, it will ruin your battery".

So -- can over charging damage battery? I am only interested in facts (no "no/yes" answers please, explanation "why" is needed here) and/or also long-standing experience.

I am interested in this issue, because as developer I will connect phone to computer for longer than 2 hours, and charging is unavoidable.

Android: 4.0.4

This is so bloody annoying. During any call whether on speaker or using the phone in the traditional manner, the screen shuts off after a minute or so, even though my display is set to shut off after 5 minutes of inactivity.

I have taken the following actions to no avail:

my screen protector does not cover the proximity sensor;

the proximity sensor is clean;

I have disabled proximity sensor (phone>call settings>turn on proximity sensor);

I have disabled automatic brightness (settings>display>brightness); and

set the Bluetooth visible time-out setting to "never time-out" (settings>bluetooth>settings>visible time-out)

All of the above have been suggested within this and/or other forums. However, none of these solutions corrected this most annoying problem.

Some have suggested that the phone is the issue - however, I suspect that there may be a software issue and that a patch or fix may be available and would hate to have to exchange phones yet again.

Any and all suggestions would be most welcome.

Installing Android using only fastboot on HTC Vision
I lost my system somehow. My phone turned off and reboots during starting up.

I'm only able to go to hboot (fastboot/recovery etc.) on my phone, and I'm unable to run Android system.

I have tried many possible solutions with help of #g2root on freenode:

First I downloaded the stock ROM and saved it to SD card (PC10IMG.zip).

It begins to load, and I see [1]-[12] positions.

When I agree to install, there's "- Updating" text near to "[1] Bootloader". Nothing else happens for more than 30 minutes.

Then we tried to get rom.zip from official HTC Unlocker for Desire Z, saving it to the SD card.

This time the only list item there was "[1] Bootloader" and also "Updating" text and nothing happens.

The last thing I tried was to run EXE file from HTC that is supposed to update my HBOOT.

It also doesn't work.

Here are my HBOOT params:

VISION PVT SHIP S-ON

  ?HBOOT-0.85.0013

  MICROP-0425

  RADIO-26.10.04.03_M

  eMMC-boot

CM10 Kindle Fire nonresponsive usb storage
Finally got around to rooting my Kindle Fire, first thing I did was install the latest CM, in my case, CM10. So I played with that for a while and decided to flash to the next ROM, plugged it into my computer, enabled usb storage, began to transfer the new ROM to the /sdcard and as it was doing so, the Kindle unplugged itself (or so the computer thought), and is currently stuck on the 'USB storage in use' screen, and has been for the past hour. Any help?</p>

I can flash Cyanogenmod though my bootloader is locked
I am using a Samsung Galaxy Nexus and CWM as recovery. Even though I locked my bootloader after installing the recovery, I can flash Cyanogenmod 10 using CWM without any errors. Now I am wondering why this works?

When I unpack the Cyanogenmod 10 .zip on my computer, there's also a boot.img, so I guess it also replaces the bootloader? Maybe when the bootloader is locked, this step is skipped (but no error shown) and the stock ROM bootloader is also OK?

This ends up in my final question: While it works, am I maybe missing a bootloader update when flashing Cyanogenmod while my bootloader is locked?

How to disable "Forgot Password" on the lockscreen

How can I disable or hide that Forgot Password option before screen lock to force me to factory reset?

Edit:
I have tried without Google account: after 5 try still the Forgot password, but than it is a Factory reset, so it is related to Google account.

How can I reset my SGH-999?
I have a Samsung Galaxy S3 (SGH-999) and am trying to do a hard reset. Somewhere along the line, things got a bit messed up. It keeps telling me I have a firmware update, and when I click start to start the update, the phone reboots and does not boot back up. To restart it, I remove the battery and then restart, but at the top it says "Recovery Booting" in blue text.

So then I shut down (remove battery) and restart in flash mode. Then when I restart, it boots up telling me that the upgrade failed.

So now, I want to completely reset my phone, but am unable to do so. I've tried all of the methods listed at http://www.hard-reset.com/samsung-galaxy-s3-hard-reset.html and no success, it continues to boot into the Samsung Galaxy SIII screen with the blue text at the top.

Any ideas?

My Samsung Galaxy Nexus won't turn on
My phone is 8 months old, and since I got it, I've had it suddenly die on me twice, but both times it came back to life within 2/3 days. After the second time it happened, I tried to bring it into samsung to get it checked, but they told me because my screen had a crack, they weren't able to honour my warranty anymore. Hence, I'm in this sticky situation where I still have 2 years and 2 months of my contract left before I can even consider getting a new phone.

This time, the phone has been dead for over a week.

I tried these commonly advised tips:

removing the battery, leaving it out for periods of 5 mins to even a day or two

holding the off button for 30 seconds

holding the off + volume (down) button

holding the off + volume (up) buttons

options 3 and 4 in various successions

And nothing works! Please help! Any suggestions or advice at all would be great!

Unable to view emails in folders other than inbox
I am using Hotmail app developed by "Microsoft + Seven" to read emails. I have many folders other than inbox to segregate my emails. There are rules set in web version of Hotmail, that moves the incoming emails to respective folders. These rules are working fine and I observe all my moved emails correctly in web version.

However, my Android client notifies me and displays only about the new emails in my Inbox. I had selected those other folders in the app to download email:

But still, I neither do not get any notifications on these folders nor any email when I open the folder in the client. When I open the folder I get "No messages" message in the screen, through there are messages. When I press "Check email" option in the context menu while I am viewing the folder, a toast message "Check email request sent" is displayed and goes off with no emails shown.

Though I am not worried about the notification about the new emails in the folders other than inbox, I do want to read them in the client. Presently. I am doing this by opening web version in a browser.

I have seen the following questions which are close but not to be considered as duplicate.

How can I sync all folders from an Exchange server (not just the
Inbox)? I am not using an exchange server. I am using Hotmail POP or IMap servers.

How can I get push notifications for emails in
sub-folders? This talks about Gmail and my Gmail client is working perfectly fine. But in Gmail, there are no folders only labels.

Can I get a notification when an email arrives in
a sub folder? I am not much worried about notification. But as said in @Zuul's explanation regarding Hotmail, all done; no fun.

I haven't tried other email apps including stock app in Android 2.3.3 LG V20G P500.

Share intent handler that will post source links from Twitter to Instapaper?

It also did the work of following URL-shorteners until it reached the source link and only posted the source link to IFTTT.

I have an Android app that responds to the "Share" intent that I can use from the Twitter app to send links to Instapaper, but it only sends the Twitter.com link and does not scrape the contents of the tweet.

Is there any Android app that implements the "Share" intent that will scrape tweets for me that I share from the Twitter app and post the first embedded link to Instapaper?  I'd take recommendations for other Instapaper-like services but I'd prefer Instapaper if at all possible.

Default video player not automatically expanded since last update?
Lately I've noticed that the default video player on Android is not automatically expanding to the full size of the screen, instead it is playing videos at the original resolution (which can be quite small). We noticed this problem on our tube site, and since confirmed it happens with every other tube site that we've tested.

We also tested on 2 different Galaxy S3's, one with the latest updates and one without any updates in the last few weeks. The one with the latest updates plays the video at the original resolution (very small on these phones) and the one with the latest updates plays the videos automatically expanded to use the full screen.

I'm wondering if there is a way to force Android (from a website) to always play the videos expanded, and if not, if this is a bug of one of the latest updates?

Typical applications could be to move photos off the phone (Move it out on my desktop and have it reflected on the phone), and to put podcasts on the phone.

If I could put Dropbox to sync the root of the SD card or perhaps the whole file-system it would it principle do it ( Most of these kind of apps use a dedicated folder, which is not logically on the SD card).

One issue is that i already use DropBox for other purposes, so it would be better to use the free quota of another provider.

Samsung Galaxy Tab 7 (GT P1000 with 2.2version android) stuck in boot-loop on update to CM10
I have a Samsung Galaxy Tab 7 (GT P 1000) with Android 2.2. A couple of days ago, I decided to update my Tab to JellyBean, and I searched the web for its procedure

I found a HowTo at AndroidAuthority. After downloading the files and placing them on the internal SD, I followed its procedure about the recovery mode. My tab started to update but in the middle of upgrading it stopped and restarted.

After that, my tab continuously follows this trend 1. Booting 2. Loading the OS 3. Rebooting 4. Go to 1! I could not even return its OS to is previous state!

I could not even go to the Recovery mode to do something.

Someone told me that each phone has a ROM or something like downgrading thing which I should download it and follow another procedure. I think I should do something like formatting and reinstalling a fresh, brand new Android OS on it like the procedure when we want to install a new Windows OS on our PC.

Is there a way to set up anything on the device so I can write the messages to a logfile or the display of the device? I don't want to install a different bootloader, I would like to see the default bootloader "in action".

I'm using a rooted HTC Desire with S-OFF. Linux and Windows are available, communication to the device is possible via USB and WLAN.
Other suggestions posted in this forum did not help (like this, if I add the suggested lines it just boots up normally. Or this, since I cannot use ADB).

Any help is very appreciated.

Best regards

Filling in the blanks in a Kindle book
I'm considering buying a Kindle version of a workbook which requires a lot of blanks to be filled. I'm aware of "Note" feature in Kindle app for Android but texts that are entered this way do not show on book pages (in blanks) as they would in a paper version of the workbook  (there are only icons indicating notes) and this limits their usefulness.

Any ideas how to work around this and make Kindle workbooks as usable as the paperback ones?

Packet monitoring on phone
I suspect one of the apps on my phone is sending private data back to its servers. I'd like to analyze the traffic generated by this app. Specifically, I'd like to monitor the requests it's making (not the amount and destination but the parameters in each request). Is there any way to do this on my unrooted phone? I thought of connecting my phone and my laptop to the same WiFi network and then analyzing the traffic but since my laptop runs Win7 it seems it's not an easy thing to do (or maybe even not possible according to Wireshark's docs).

Is there any way to do this?

Unable to hear caller when using native internet (SIP) calling on Jelly Bean
I am using the native internet calling feature provided on Jelly Bean. (I believe this feature has been available since Gingerbread.)  I can make outgoing calls without issue.  Since my SIP account is connected to a PSTN (i.e. phone number) I can also receive calls.  However, when I answer an incoming call the calling party can hear me, but I cannot hear the caller on the other end.

My guess is that this is some kind of NAT problem.  See here, for example.  With other third-party SIP apps it is possible to use STUN to eliminate the problem. I don't see any corresponding options for the native SIP interface, though.  So I have two related questions:

1. Is it possible to enable/use STUN with native internet calling?

2. How can I troubleshoot problems with native internet calling?

Nothing happens.

I can connect a Logitech wireless mouse to it and I can use my phone via the mouse. So everything are connected, with power.

I read that I need to mount the external drive and the SD card reader. So I opened Astro but it doesn't seem to auto mount.

Why do some apps get frozen every time I reboot?
After rooting my Galaxy Nexus (international GSM version), I looked around a bit with Titanium Backup and found several system apps that were frozen. Among them are: Google Earth, Google Play Books, Google Play Magazines, and Google Wallet.

I thawed them and found that Google Play Books and Magazines wouldn't work here in Korea, and Wallet seemed to assume that it was in the US. Meanwhile, Google Earth worked just fine.

When I rebooted my phone, the apps I'd unfrozen were frozen again. I thawed Google Earth again and didn't bother with the others.

More recently, Google Play Books has magically thawed itself and Google Play (both the app and the web interface) spam me with promos for books in a language I don't read (Korean), despite the fact that my phone is set to English.

Google Earth still tries to hide on every reboot.

Why are these system apps doing this? If they're part of the ROM, they should be available at all times, right? I can kind of understand hiding apps that don't work outside the US (like Google Wallet), but why hide Google Earth? It's relevant worldwide by its very nature.

Cerberus is flashed, so I think I'll have a better chance at recovering my phone if it's usable and not completely locked.

I have set a profile with tasker + secure settings to shutdown after 3 failed PIN attempts (which is different than the encryption password), so I should be save there and a thief would be forced to guess my much safer encryption password.

I know that I can do it with cerberus, but only manually.

@Robert answered a similar question, that is possible with encryption, but doesn't get specific.

Bonus point: Is there any possibility to use a pattern instead of a PIN for the display lock? It's unavailable after encrypting..

问:
Rooting/unlocking Android Nexus One with broken power button using Linux terminal tools
I am attempting to get Cyanogenmod onto my Nexus One, but am running into far more problems than expected.  The information on rooting Android devices seems heavily fragmented across the web and the tools unreliable.  At least in my case, SuperOneClick has proven a complete misnomer.  So I'd like to go back to basics - executing as many of the commands as possible from a Linux terminal to get the phone rooted/unlocked/whatever else has to happen to get Cyanogenmod installed.  The two constraints I'm working with here are as follows:

The device is running Android 2.2.1 (I downgraded from 2.3.x using the PASSIMG method).

The power button on the device is broken, so any method which requires pressing/holding it is ruled out.

The problem I am having is that even after following Linux-centric guides, I get to the point of installing the SuperUser app followed by the ROM Manager app, but I'm never prompted to give ROM Manager superuser permissions and so can't flash the ClockworkMod recovery.

Below I describe the steps I've been taking so far, based on the How To Root Nexus One Running Android 2.2.1 From Ubuntu Linux guide.

Download/extract/move Nexus One Softroot files to same directory as adb

From adb directory, execute the following commands:

sudo ./adb push psneuter /data/local/tmp/psneuter

sudo ./adb push busybox /data/local/tmp/busybox

sudo ./adb push su /data/local/tmp/su

sudo ./adb shell chmod 755 /data/local/tmp/psneuter

sudo ./adb shell chmod 755 /data/local/tmp/busybox

sudo ./adb shell chmod 755 /data/local/tmp/su

sudo ./adb shell cd /data/local/tmp ./psneuter

sudo ./adb shell

After executing sudo ./adb shell as above, I get the # prompt, which is purported to indicate that rooting was successful.

Still following the guide, I then execute the commands which purportedly make root permanent:

mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system

cd /data/local/tmp

./busybox cp busybox /system/bin

chmod 4755 /system/bin/busybox

busybox cp su /system/bin

chmod 4755 /system/bin/su

exit

exit

Again, still following the guide, I execute the commands which purportedly set the /system partition back to read-only:

sudo ./adb shell

su

mount -o remount,ro -t yaffs2 /dev/block/mtdblock3 /system

exit

exit

Now, I download the SuperUser app from the Android Market and open it to make sure it's running.

Next, I download the ROM Manager app from Google Play (looks like it pulled a sneaky and upgraded from Android Market to Google Play here).

I run ROM Manager and choose Flash ClockworkMod Recovery.  I'm prompted to confirm the phone is a Google Nexus One and then ROM Manager runs for about 30 seconds (yellow program bar goes all the way) before spitting out An error occurred while attempting to run privileged commands!.  And this is the point I am stuck at.

I should note that at no point am I prompted by the SuperUser app to give the ROM Manager app super user permissions.  I don't restart the phone or do anything else throughout all of the steps I've described above, so I can't see any reason for root to have been lost at any point.  In fact, if I execute the command sudo ./adb shell after all this, I still get the # prompt indicating root.  And when I execute id afterwards, I get uid=0(root) gid=0(root) -- further confirmation of root.  I really am stuck on this one.  I've spent a lot of time digging through forum posts and online articles, but the signal to noise ratio is poor and I haven't been able to find anything that actually works.  Can someone suggest where I am going wrong?

I'd like to create a contact, and "push" these messages to that user. I wouldn't mind being able to "clean" up some of the static fluff in the message as well (Getting rid of the "header" crap and just saving what's after the "MSG: " part.

I'm a baby programmer, so I may have to break down and make this myself... but is there something out there already taht might do what I'm looking for already?

Why does my Samsung Galaxy S2 have duplicate calendar events?
Why does my Samsung Galaxy S2 have duplicate calendar events?  I am using Outlook calendar and have downloaded the Google calendar to allow it to sync.  When I use the Samsung Kies Program to sync the Samsung Galaxy S2 I end up with multiply duplicates of some of the events and not others. </p>


问:
Why does my app crash when I download it through 3G?
I have developed an application and published it on the Play Store.

My problem is that when I download it from the Play Sore via 3G, the application crashes. However, when I download it via wifi it runs without problem.

Also, after downloading (via wifi), if I disable wifi and enable 3G, the application can be launched and works fine without crash/problem.

Any suggestion would be appreciated.

Bluetooth PAN issue
I have to setup the bluetooth PAN on my development board. On my device most of the functions working fine -- but PAN is having problem.

I am tring to set up Static IP for my board , which will be a client. My master is set up on the Ubuntu 12.04 PC.

I can make the connection via pand:

```<code>pand -c <bt address of the ubuntu PC>
</code>```

[my master is working in GM mode]

To bring up the bnep interface below are my commands:

```<code>netcfg bnep0 up
ifconfig bnep0 172.22.22.10 netmask 255.255.255.0
</code>```

but still I can not ping the master and client from master.

Do i need to do any other setting?

Thanks

Bluetooth headset changing pairing mode into "media audio" only
I've got a Plantronics bluetooth headset which when I pair to my phone (AT&T GS3 4.0.4) works very well at first, with the headset appearing as "Connected to phone and media audio." In this mode I can e.g. listen to music and automatically transition to talking on incoming/outgoing calls.

However, recently the pairing changes, within seconds after ending a phone call, to just "Connected to media audio." In this mode I can still listen to music but not talk on the phone via the headset... In order to return to the "phone and media audio" mode, I have to disconnect and then reconnect the headset.

This is extremely annoying. Any ideas what may have started causing this and for any remedies?

Once installed, how do I activate Firebug in Mobile Firefox?
I went to the getfirebug.com web site, where I was able to install Firebug under Firefox 1.10.6 (the Beta version of Firefox from the Play store).  It said the install was successful.  Now what?  How do I activate Firebug?  There are no new icons that I can click on like there are on the desktop version, and long-clicking on the page isn't doing anything either.  I see no new menu options either.  In the add-ons menu I see Firebug, but it only offers the choice to disable or uninstall, so I know it's there and installed.</p>

Samsung GT-i9300, JellyBean, Headset button changing sound profile
I'm running Android 4.1.1 stock firmware (JellyBean) on my Samsung GT-i9300.

After updating, I'm having some issues with headset controls. I am using the official Samsung headset which came with my phone.

The issue with long press opening Google Now is annoying, but it doesn't seem to have a solution that I can find. However, when I press the pause/play button on my headset, it changes my sound profile to Normal - this is really annoying as I tend to listen to music in work, and need to keep manually changing my profile to vibrate after EVERY time I play/pause/skip a track.

I've tried using the Jays Headset Controls app to no avail... does anyone have any idea on what I could do to fix this issue?

Can I install a micro-SD card into my Note 2 after I've enabled device encryption?
I recently got a Note 2 and enabled device encryption. I want to put a micro-SD in it now to expand my storage capacity, but when I go to settings, it won't let me mount the card. Is it because of the device encryption? Is there a way to add this drive without decrypting and re-encrypting?</p>


问:
Changing some system file values in Android failing
I am trying to change some sys values but I don't seem to be having much success.

In my case I am trying to change values of files in the folder

"/sys/devices/platform/omap/musb-omap2430/musb-hdrc/usb1/1-0:1.0"

e.g. the file bInterfaceClass which currently has value 09

My tries: (In shell, as root)

```<code>chmod 777 bInterfaceClass
echo 07 >> bInterfaceClass
</code>```

I didn't receive an error but when looking up the value

```<code>cat bInterfaceClass
</code>```

It is still 09

Now looking up this file in Root Explorer, I can see that the last modification date of the file has changed, so my guess: something resets the value of such a sys file as soon as it changes.

Can anyone shine some more light on this issue?
How can I change the value?
