body: <p>How can I open a udp multicast video stream on android ?</p>
  
  <p>I tried this code:</p>
  
  <pre><code>public class androidActivity extends Activity {
  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);
  
      VideoView videoView = (VideoView) findViewById(R.id.videoView);
      MediaController mediaController = new MediaController(this);
      mediaController.setAnchorView(videoView);
  
      Uri video = Uri.parse("udp://224.1.1.1:1234");
  
      videoView.setMediaController(mediaController);
      videoView.setVideoURI(video);
      videoView.start();
  }
  </code></pre>
  
  <p>}</p>
