Android的YouTube視頻與RSTP和vnd.youtube://打

Question

//此方法只顯示了YouTube上載

1. Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("vnd.youtube://" + videoId)) startActivity(intent);

//第二種方法是不是在所有 2播放視頻。

public class MyTask extends AsyncTask<Void, Void, Void> 
    { 

    @Override 
    protected void onPreExecute() { 
     // TODO Auto-generated method stub 
     super.onPreExecute(); 
     mProgressBar.setVisibility(LinearLayout.VISIBLE); 

    } 

    @Override 
    protected Void doInBackground(Void... params) { 
     // TODO Auto-generated method stub 
     url=getUrlVideoRTSP(urlRstp[0]); 
     rstlUrl=Uri.parse(url); 

     return null; 
    } 

    @Override 
    protected void onPostExecute(Void result) { 
     // TODO Auto-generated method stub 
     super.onPostExecute(result); 
     //Toast.makeText(VODVideoPlayActivity.this, url, Toast.LENGTH_LONG).show(); 
     //System.out.println(url); 

     mVideoView.setVideoURI(rstlUrl); 
     //MediaController mc = new MediaController(VODVideoPlayActivity.this); 
     //mVideoView.setMediaController(mc); 
     //mVideoView.requestFocus(); 
     mVideoView.start();   
     //mc.show(); 
     mProgressBar.setVisibility(LinearLayout.GONE);   
    }

調用新的VideoAsyncTask（）。execute（）;

private class VideoAsyncTask extends AsyncTask<Void, Void, Void> { 
    ProgressDialog progressDialog; 
    String videoUrl; 

    @Override 
    protected void onPreExecute() { 
     super.onPreExecute(); 
     progressDialog = ProgressDialog.show(GallaryActivity.this, "", 
       "Loading Video wait...", true); 
    } 

    @Override 
    protected Void doInBackground(Void... params) { 
     try { 
      // 

      String id = ""; //video id of youtube 

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

    @Override 
    protected void onPostExecute(Void result) { 
     super.onPostExecute(result); 
     progressDialog.dismiss(); 
     /* 
     * videoView.setVideoURI(Uri.parse(
     * "rtsp://v4.cache1.c.youtube.com/CiILENy73wIaGQk4RDShYkdS1BMYDSANFEgGUgZ2aWRlb3MM/0/0/0/video.3gp" 
     *)); videoView.setMediaController(new 
     * MediaController(AlertDetail.this)); videoView.requestFocus(); 
     * videoView.start();

     if (myvideoview.isPlaying()) 
      myvideoview.stopPlayback(); 
     myvideoview.setVideoURI(Uri.parse(videoUrl)); 
     MediaController mc = new MediaController(GallaryActivity.this); 
     myvideoview.setMediaController(mc); 
     myvideoview.requestFocus();
