  Just override onbackpressed method 
stop everything here and close activity.

@Override
    public void onBackPressed() {
        // TODO Auto-generated method stub
        super.onBackPressed();
finish();
    }

From your logcat:

android.app.SuperNotCalledException: Activity {com.test.test/com.test.test.MainActivity} did not call through to super.onDestroy()

Add super.onDestroy() to your overridden onDestroy() method.

when i press back buttom the app closed and i do not want that

You can override onBackPressed() in your activity and not call super.onBackPressed() or finish() there to prevent the back key from finishing your activity. Though usually it's a bad idea to make your app behave not according to user expectations.

i wanna stop app only when press back butom only if the stram off and if is on and press back buttom i want it to still work – Mohamed Elsayed Aug 06 '14 at 11:32
You can write the logic in `onBackPressed()`. Call `finish()` when in fact you want to finish the activity. – laalto Aug 06 '14 at 11:32

if you want to close app @Override public void onBackPressed() { // TODO Auto-generated method stub super.onBackPressed(); finish(); } otherwise remove finish(); – user3279053 Aug 06 '14 at 11:28
yes i want to close app when i press back butoom but only when the player off but if is working and press back buttom i want to still work – Mohamed Elsayed Aug 06 '14 at 11:33
so check with condition if not playing then finish(); otherwise not – user3279053 Aug 06 '14 at 12:51
