I upvoted Jeffrey Blattman's answer above, but here is the full code that shows how to use setDataSource with an audio file that you put into your app resources (raw). Also a couple of other things I picked up in my travels...

static public void playAlarmSound () {
    final MediaPlayer mediaPlayer = new MediaPlayer();
    new AsyncTask() {
        @Override
        protected Boolean doInBackground(Void... voids) {
            try {
                mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
                    @Override
                    public void onCompletion(MediaPlayer mp) {
                        mediaPlayer.reset();
                        mediaPlayer.release();
                    }
                });
                mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                    @Override
                    public void onPrepared(MediaPlayer mp) {
                        mediaPlayer.start();
                    }
                });
                AssetFileDescriptor afd = getContext().getResources().openRawResourceFd(R.raw.nameofyourresource);
                if (afd == null) return false;
                mediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
                afd.close();

                if (Build.VERSION.SDK_INT >= 21) {
                    mediaPlayer.setAudioAttributes(new AudioAttributes.Builder()
                            .setUsage(AudioAttributes.USAGE_ALARM)
                            .setContentType(AudioAttributes.CONTENT_TYPE_MUSIC)
                            .build());
                } else {
                    mediaPlayer.setAudioStreamType(AudioManager.STREAM_ALARM);
                }
                mediaPlayer.setVolume(1.0f, 1.0f);
                mediaPlayer.prepare();
                return true;
            } catch (Exception e) {
                e.printStackTrace();
            }
            return false;
        }

    }.execute();
}
