How to play an android notification sound

I was wondering how I could play a notification sound without playing it over the media stream. Right now I can do this via the media player, however I don't want it to play as a media file, I want it to play as a notification or alert or ringtone. heres an example of what my code looks like right now:

MediaPlayer mp = new MediaPlayer();
mp.reset();
mp.setDataSource(notificationsPath+ (String) apptSounds.getSelectedItem());
mp.prepare();
mp.start();
