播放声音表单原始文件夹

Question

我正在尝试从原始文件夹播放我想要做的声音 -

    Uri alert = Uri.parse("android.resource://" + this.getPackageName() + "/" + R.raw.ring_tone);
    mMediaPlayer = new MediaPlayer();
    AudioManager am = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
    try {
        mMediaPlayer.setDataSource(this, alert);
        mMediaPlayer.setVolume(Float.parseFloat(Double.toString(am.getStreamVolume(AudioManager.STREAM_NOTIFICATION) / 7.0)),
                Float.parseFloat(Double.toString(am.getStreamVolume(AudioManager.STREAM_NOTIFICATION) / 7.0)));

        mMediaPlayer.setLooping(true);
        mMediaPlayer.prepare();
        mMediaPlayer.start();

        Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                mMediaPlayer.stop();
                mMediaPlayer.release();
            }
        }, 1000 * 60);

但我收到例外E/MediaPlayer﹕ Uri is <URL suppressed> D/MediaPlayer﹕ start() mUri is <URL suppressed>

我根据请求添加了LogCat -
