How to stop android notification ringtone after 30 seconds?

Question

I\'m writing an app that notifies a user of very time sensitive information, and I think a lot of them would want to use a phone ringtone instead of just the short notification

Answer 1

This should do it.

....
mediaPlayer.start();
....
final Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            if (mediaPlayer.isPlaying())
                mediaPlayer.stop();
        }
    }, timeout);
