的Android的MediaPlayer无法播放网络媒体：准备失败：状态=为0x1

Question

我想打从Web服务的一首歌，我写的代码如下

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.content); 

    startButton = (ImageButton) findViewById(R.id.start); 

    Intent intent = getIntent(); 
    mp3Path = intent.getStringExtra("mp3Path"); 

    player = new MediaPlayer(); 

    startButton.setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      try { 
       if(player != null) 
        player.stop(); 
       player.setDataSource(mp3Path); 
       player.prepare(); 
       player.start(); 
      } catch (IllegalStateException e) { 
       e.printStackTrace(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
     } 
    }); 
} 

但是当我点击该按钮，它抛出以下异常，我被告知有关于准备的错误：

04-13 17:23:13.186: E/MediaPlayer(401): stop called in state 1 
04-13 17:23:13.186: E/MediaPlayer(401): error (-38, 0)
