Android youtube视频播放rstp和vnd.youtube://

Question

//此方法只显示youtube loading

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

//第二种方法根本不播放视频 2。

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);

调用新的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

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