Calling:

  • System.exit(0);
  • Process.killProcess(android.os.Process.myPid());

Both of which are definitely not a good idea!

Instead use the activity's finish(); method - let Android handle the cleanup of RAM management, which it is very good in doing so!

If you do not want your activity to be shown in the activity stack, the flags, Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP would usually suffice for launching another activity.

OR specify in your AndroidManifest.xml in your activity tag, android:noHistory="true".

System.exit will exit the VM and Android will kill this process.

Activity#finish() is usually the popular choice, but this does not need to be executed right away and also only affects this particular Activity, not the whole process.

Just FYI: killing apps manually is not a good app design in Android (except maybe some special situations). If you could explain why you want to kill your app, we can probably tell you a better solution.

use single line code

System.exit(1);

or 

android.os.Process.killProcess(android.os.Process.myPid());
