Android Mediaplayer 无法加载

Question

我有一个调用这个服务类来播放媒体播放器的类

 class MusicService extends Service implements OnCompletionListener {
 MediaPlayer mediaPlayer;

   @Override
  public IBinder onBind(Intent intent) {
 return null;
  }

  @Override
  public void onCreate() {
  mediaPlayer = MediaPlayer.create(this, R.raw.s);// raw/s.mp3
  mediaPlayer.setOnCompletionListener(this);
  }

 @Override
public int onStartCommand(Intent intent, int flags, int startId) {
  if (!mediaPlayer.isPlaying()) {
  mediaPlayer.start();
  }
return START_STICKY;
 }

public void onDestroy() {
   if (mediaPlayer.isPlaying()) {
   mediaPlayer.stop();
   }
   mediaPlayer.release();
 }

   public void onCompletion(MediaPlayer _mediaPlayer) {
 stopSelf();
 }

}

我不希望它加载原始文件我希望它加载一个路径，该路径是调用此服务的类中的一个字符串。

 String path = "path is here"

 private void playAudio(String url) throws Exception{
 Intent music = new Intent(this,MusicService.class);
 intent.putExtra("paths",path)
 startService(music);

我该怎么做...

音乐文件来自于sd卡

只需使用这个------------

MediaPlayer md=new MediaPlayer();
        md.prepare();
        md.setDataSource(path);
