2 - 我有$ C $下进度条，但我不知道放在哪里code当视频从互联网上下载。

下面是我的code，你可以检查它。先谢谢了。

  myVideoView =（VideoView）findViewById（R.id.surface_view）;


        尝试
        {

            myVideoView.setVideoURI（Uri.parse（http://www.MY_DOMAIN_NAME.com/videos/video1.mp4））;
            myVideoView.setMediaController（新的MediaController（本））;
            myVideoView.requestFocus（）;
            myVideoView.start（）;
        }
        赶上（例外五）
        {
            Toast.makeText（getApplicationContext（），没有媒体发现，Toast.LENGTH_LONG）.show（）;
        }

        乌里视频= Uri.parse（将videoPath）;
        v.setMediaController（的MediaController）;
        v.setVideoURI（视频）

        v.setOn preparedListener（新在preparedListener（）{

            公共无效于prepared（MediaPlayer的MP）{

I am developing a sample media player app in Android to play online videos, I have developed some code to play videos. It plays video from SD card very well, but I am facing two issues in this respect.

1- when I open the app for online videos it shows the video but it does not play the video and after a while it displays an alert dialog having message "Sorry, this video cannot be played".

2- I have code for "Progress bar", but I don't know where to put the code when the video is downloading from the internet.

Here is my code you can check it. Thanks in advance.

myVideoView = (VideoView) findViewById(R.id.surface_view);


        try
        {

            myVideoView.setVideoURI(Uri.parse("http://www.MY_DOMAIN_NAME.com/videos/video1.mp4"));
            myVideoView.setMediaController(new MediaController(this));
            myVideoView.requestFocus();
            myVideoView.start();
        }
        catch(Exception e)
        {
            Toast.makeText(getApplicationContext(), "No Media found", Toast.LENGTH_LONG).show();
        }

try like this

 VideoView v;
 MediaController mediaController;
 ProgressDialog progressDialog;

then

public void playvideo(String videopath) {
    Log.e("entered", "playvide");
    Log.e("path is", "" + videopath);
    try {
        progressDialog = ProgressDialog.show(VideoPlay.this, "",
                "Buffering video...", false);
        progressDialog.setCancelable(true);
        getWindow().setFormat(PixelFormat.TRANSLUCENT);

        mediaController = new MediaController(VideoPlay.this);

        Uri video = Uri.parse(videopath);
        v.setMediaController(mediaController);
        v.setVideoURI(video);

        v.setOnPreparedListener(new OnPreparedListener() {

            public void onPrepared(MediaPlayer mp) {
                progressDialog.dismiss();
                v.start();
            }
        });

    } catch (Exception e) {
        progressDialog.dismiss();
        System.out.println("Video Play Error :" + e.getMessage());
    }

}
