How to remove default/preloaded applications like browser,camera,contacts...

Suppose u have developed a new contact application which is much better than the preloaded contact application in android..so when u want to install it eclipse will throw u bunch of error saying "Please uninstall the contact application first by adb uninstall "package name".

When u tried to do that...Alas...it did not work...saying FAILED

The reason for this is that u don't have the root access and u have only read only access..So to change the access and remove the contacts(any application) follow the below instructions..

  1. Start your emulator
  2. Execute "adb shell" in on terminal from SDK_ROOT/tool folder
  3. Mount your system folder with read/write permission

    mount -o remount,rw /dev/block/mtdblock3 /system
  4. Go to system/apps folder

    cd /system/apps
  5. Remove APK

    rm defaultapp.apk

 

Bingo Check your emulator.The default application is gone.Now u can install your application with eclipse.
N.B.:This is required to remove the apps already present in emulator...If u want to remove some of the application u've installed then just do


adb uninstall yourpackagename

or


adb shell
cd /data/app
rm yourapp.apk

So enjoy Being an Android Programmer........

Play video inside OpenGL ES by using MediaCodec

In Android 4.1 (API 16) and above, MediaCodec is introduced by Android. By using MediaCodec, we can easily decode video without using Android NDK, like creating video playback application, etc. In game development, video is also needed to make the game environment more realistics, like when you are playing a racing game with video banner around the track. In here, I'll introduce of how to decode the video and render it into OpenGL ES. Firstly, we prepare some stuffs to decode the video, like MediaExtractor and MediaCodec. private boolean initExtractor() { extractor = new MediaExtractor(); try { extractor.setDataSource(mFilePath); } catch (IOException e) { return false; } // get video track for (int i = 0; i < extractor.getTrackCount(); i++) { MediaFormat format = extractor.getTrackFormat(i); String mime = format.getString(MediaFormat.KEY_MIME); if (mime.startsWith("video/")) { ...
