Android Media Player Url特定问题

Question

我在我的一个android项目中工作，在这个项目中我正在用媒体播放器播放声音。当我使用this网址播放歌曲时，我得到一些如下的IOException，但歌曲在MediaPlayer中播放良好。问题应该是什么？

public void startMediaPlayer(String url) {

    Log.e("urlToPlay==>",url);
    // start new song for play

    if(mediaPlayer==null){
        mediaPlayer=new MediaPlayer();
    }else{
        mediaPlayer.reset();
    }
    Uri myUri1 = Uri.parse(url);

    mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
    try {

        mediaPlayer.setDataSource(getActivity(), myUri1);
        mediaPlayer.prepareAsync();

        mediaPlayer.setOnPreparedListener(new OnPreparedListener() {

            @Override
            public void onPrepared(MediaPlayer player) {
                playPause=true;
                player.start();
                mediaFileLengthInMilliseconds = player.getDuration(); // gets the song length in milliseconds from URL

            } 
        });

        mediaPlayer.setOnCompletionListener(new OnCompletionListener() {

            @Override
            public void onCompletion(MediaPlayer mp) {
                playPause=false;
           }
        });

        mediaPlayer.setOnErrorListener(new OnErrorListener() {

            @Override
            public boolean onError(MediaPlayer arg0, int arg1, int arg2) {

                Log.e("onError==>","Something went wrong"+arg1+"");
                Log.e("onError==>","Something went wrong"+arg2+"");
                return false;
            }
        });

    } catch (IllegalArgumentException e) {
        e.printStackTrace();
        mediaPlayer.release();
    } catch (SecurityException e) {
        e.printStackTrace();
        mediaPlayer.release();
    } catch (IllegalStateException e) {
        e.printStackTrace();
        mediaPlayer.release();
    } catch (IOException e) {
        e.printStackTrace();
        mediaPlayer.release();
    }
}

播放文件时出现以下异常

尝试添加类似"file://“或"http://”的url方案。当我在尝试播放本地文件时遇到同样的异常时，这对我很有效。
