Error in opening streaming video

问题

I'm trying to open video stream by giving the url of the video. I'm using VideoView.Here is my code:

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);        
        VideoView videoView = (VideoView) findViewById(R.id.stream_video_view);
        videoView.setVisibility(View.VISIBLE);
        MediaController mc = new MediaController(this);     
        mc.setAnchorView(videoView);
        mc.setMediaPlayer(videoView);
        videoView.setMediaController(mc);
        Uri uri = Uri.parse("http://172.16.154.106:8080");
        videoView.setVideoURI(uri);
        videoView.requestFocus();
        videoView.start();
    }     
}

LogCat:

On executing this, I'm not getting any error but I'm getting a dialog box with title "cannot play video" and with message "Sorry, this video can't be played". Any ideas why my code is not working?

First check that you have added INTERNET permission in your manifest.

Next check that what is the extension of your video format.

This link shows what files Android phones and tablets support, with both codec and filename extension information provided. However, an Android application can use media codecs either provided by any Android-powered device, or additional media codecs developed by third-party companies. Therefore, if you want to play videos on Android, find a multi-format video player or convert videos to Android compatible formats.

See this Android Supported Media Formats link.
