      mExitApp = (Button)findViewById(R.id.exit_app);

           final MediaPlayer mp = MediaPlayer.create(this, R.raw.sample2);

            mExitApp.setOnClickListener(new View.OnClickListener() {

                @Override

                public void onClick(View v) {

                    mp.start();
    
                    ScoreActivity.this.finish();

                    System.exit(0);
    
                }
            });

Answer 1

A quick and dirty way would be to wait for the sound to end playing before finishing the activity/process.

    public void onClick(View v) {
                    mp.start();
                    final Handler handler = new Handler(Looper.getMainLooper());
                    handler.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        ScoreActivity.this.finish();
                        System.exit(0);
                      }
                    }, 300);
                }

A more cleaner solution would probably involve a MediaPlayer.OnCompletionListener.

mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
    public void onCompletion(MediaPlayer mp) {
        finish(); // finish current activity
    }
});

Or you could play the sound in a foreground/background service. But then you shouldn't kill the entire process (System.exit(0)) like you do now ofc.
