Android Question
onDestroy() method doesn't work
first I used onDestroy() method as below to make something when my app is closed.
@Override
protected void onDestroy()
{
super.onDestroy();
mediaPlayer.stop();
mediaPlayer2.stop();
}
But it causes a runtime error. I used onStop() method instead and problem was solved. But I wonder why onDestroy doesn't work? Can you explain please.
@Override
protected void onStop()
{
super.onStop();
mediaPlayer.stop();
mediaPlayer2.stop();
}
I was made some changes on my code and now there is no error when I
changed onStop() with onDestroy() I can't understand how but it works.

My guess would be that your mediaPlayer variable was nulled out(destroyed) before arriving in onDestroy. And the error you were seeing was a nullpointerexception.
You could put your stuff back into the ondestroy method and add a simple null test before doing anything with your mediaPlayer :
@Override protected void onDestroy() {
super.onDestroy();
if (mediaPlayer != null) {
mediaPlayer.stop();
mediaPlayer2.stop();
}
}
