结果是前两首歌曲播放得很好，但其他歌曲没有播放，几乎没有播放到最后一首歌曲！

播放流的代码（有效）：

    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();
}

SETONCOMPLETELISTENER 的规格：

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();
            }
        }
    });

是的，我总是可以提供帮助。我也遇到了这个错误，我的解决方案是检查 ANDROID MEDIA PLAYER 接收到的路径。所以要做到这一点粘贴此代码：

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

检查网址是否正确并包含扩展名。确保它不受域保护。

如果一切正常，请粘贴以下代码：

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

        mediaPlayer.start();

    }
});

我知道你们都准备好了，但也许它不起作用。
