播放MP3文件格式的Android原始文件夹中收到错误URI是<URL抑制>

我需要在我的Android应用程序中播放从原始文件夹中的声音正是我试图做的事 -播放MP3文件格式的Android原始文件夹中收到错误URI是<URL抑制>

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);

，但我得到的例外E/MediaPlayer﹕ Uri is <URL suppressed> D/MediaPlayer﹕ start() mUri is <URL suppressed>

我加入的logcat按照请求 -

更改URI声明

Uri alert = Uri.parse("android.resource://" + this.getPackageName() + "/raw/ring_tone");

或使用

URI.getScheme() or URI.getPath().

没有起色同样的事情 – Anirban

@bumba并尝试添加扩展名。我的意思是'“/raw/ring_tone.mp3”'为前。 –
