無法在客戶端打開文件

Question

我想在Android視頻視圖中播放視頻。但是當我運行代碼時，它會打開一個媒體播放器，但不播放視頻並給我一個錯誤消息並記錄貓顯示「無法在客戶端嘗試在服務器端打開文件。」這裏是我的代碼：

public class ExercisesActivity extends Activity { 

VideoView videoView; 
String videoUrl; 
public boolean flage = true; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_exercises); 

    videoView = (VideoView)findViewById(R.id.videoView); 
    new performBackgroundTask(ExercisesActivity.this).execute(); 
} 

public void onPause() 
{ 
super.onPause(); 
videoView.stopPlayback(); 
} 

private class performBackgroundTask extends AsyncTask < Void, Void, Void > 
{ 


       private ProgressDialog Dialog; 

        public performBackgroundTask(ExercisesActivity context) 
        { 
         Dialog = new ProgressDialog(context); 
        }     



      protected void onPreExecute() 
       { 

       this.Dialog.setMessage("Loading Video..."); 
       this.Dialog.show(); 

       } 


      protected Void doInBackground(Void... params) 
      { 
       try 
       { 
        String url = "http://www.youtube.com/watch?v=m5_AKjDdqaU"; 
        videoUrl = getUrlVideoRTSP(url); 
        Log.e("Video url for playing=========>>>>>", videoUrl); 
       } 
       catch (Exception e) 
       { 
        Log.e("Login Soap Calling in Exception", e.toString()); 
       } 
          return null; 
      } 


      protected void onPostExecute(Void unused) 
      { 


       if(!flage){ 

        if(Dialog.isShowing()) 
        { 
         Dialog.dismiss(); 
        } 


       } 
       else 
       { 
        videoView.setVideoURI(Uri.parse(videoUrl)); 
     MediaController mc = new MediaController(ExercisesActivity.this); 
        videoView.setMediaController(mc); 
        videoView.requestFocus(); 
        videoView.start();   
        mc.show(); 
       } 

        if(Dialog.isShowing()) 
        { 
         Dialog.dismiss(); 
        } 
       } 

      }

的RTSP鏈接不工作的由YouTube API 2.0版提供的任何數據。我不認爲它會被修復。 https://code.google.com/p/gdata-issues/issues/detail?id=4858
