Question

When I press back or home in my application, it hides, but the MediaPlayer keeps going. Is there a way to know when these buttons have been pressed and stop playback before closing?

Answer 1

You should be able to override the onPause() function in your Activity. onPause() will be called when you Activity is hidden and you can pause the MediaPlayer there.

For example,

@Override
protected void onPause() {
    super.onPause(); // Don't forget this line
    myMediaPlayer.pause() // Or whatever the function is to pause it
}
