媒體播放器錯誤（-38,0），在狀態4停止呼叫

結果是，前兩首歌曲播放良好，但其他歌曲沒有播放，並且它沒有播放任何東西而到達最後一首歌曲！媒體播放器錯誤（-38,0），在狀態4停止呼叫

代碼來播放流（它的工作原理）：SETONCOMPLETELISTENER的

private void PlayStream(String url) 
{ 
    try 
    { 
     mediaPlayer.setDataSource(url); 
    } 
    catch (IllegalArgumentException e) 
    { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 
    catch (SecurityException e) 
    { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 
    catch (IllegalStateException e) 
    { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 
    catch (IOException e) 
    { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 

    mediaPlayer.setOnPreparedListener(Canzone.this); 

    try 
    { 
     mediaPlayer.prepareAsync(); 
    } 
    catch (IllegalStateException e) 
    { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    }    

    progressBar.setVisibility(ProgressBar.VISIBLE); 
    progressBar.setProgress(0); 
    progressBar.setMax(duration); 

    new Thread(this).start(); 
}

規格：

mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() 
    { 
     @Override 
     public void onCompletion(MediaPlayer mp) 
     { 
      i++; 

      if(i<10) 
      { 
       classifica.setText("Canzoni riprodotte: "+String.valueOf(i+1)+"/10 \nPunteggio: "+punteggio); 

       mp.stop(); 
       Log.d("MPLAY", "MP Stopped"); 

       mp.reset(); 
       Log.d("MPLAY", "MP Reset"); 

       PlayStream(dieciCanzoni.get(i).get(0)); 

       tv.setText(dieciCanzoni.get(i-1).get(1) + "\n" + dieciCanzoni.get(i-1).get(2)); 

       new DownloadImageTask((ImageView) findViewById(R.id.albumImage)).execute(dieciCanzoni.get(i-1).get(4)); 

       iv.setOnClickListener(new View.OnClickListener() 
       {  
        @Override 
        public void onClick(View v) 
        { 
         Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse(dieciCanzoni.get(i-1).get(3))); 
         startActivity(intent); 
        } 
       }); 
      } 
      else 
      { 
       FineRound(); 
      } 
     } 
    });

有人可以幫我嗎？ –

你是否設法解決這個問題？ –

是的，我可以隨時提供幫助。我也有這個錯誤，我的解決方案是檢查路徑AS ANDROID MEDIA PLAYER RECIEVES IT。所以要做到這一點粘貼此代碼：

Log.d("MediaPlayer Datasource" , "The datasource is: " + url);

檢查網址是否良好，並CONTAINS擴展名。確保它沒有被域保護。

如果每一件事情都很好，並罰款粘貼此代碼：

mp.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { 
    @Override 
    public void onPrepared(MediaPlayer mp) { 
     // TODO Auto-generated method stub 

     mediaPlayer.start(); 

    } 
});

我知道你們都準備有一個，但也許它不工作。
