My java code:

VideoView videoView= (VideoView)findViewById(R.id.exerciseVideo);
    Uri uri = Uri.parse(TEST_URL);
    videoView.setVideoURI(uri);
    videoView.requestFocus();
    videoView.start();

When I run app nothing is displayed in activity and IDE does not show any errors. ANy idea, please?

Try this code.. This code works perfectly for me..

    final VideoView videoView;
    videoView = (VideoView)findViewById(R.id.videoView);
    videoView.setVideoPath("http://videocdn.bodybuilding.com/video/mp4/62000/62792m.mp4");
    videoView.start();

回答2:

As I know you shouldn't use wrap_content for VideoView height. VideoView didn't resize itself after video cached

回答3:

Kindly add Internet permission them Change layout_height wrap_content into match parent. this is a code for this problem

public class MainActivity extends Activity {
    private ProgressDialog bar;
    private String path="https://videocdn.bodybuilding.com/video/mp4/62000/62792m.mp4";
    private MediaController ctlr;
    private VideoView videoView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getWindow().setFormat(PixelFormat.TRANSLUCENT);
        setContentView(R.layout.activity_main);
      bar=new ProgressDialog(MainActivity.this);
        bar.setTitle("Connecting server");
        bar.setMessage("Please Wait... ");
        bar.setCancelable(false);
        bar.show();
       if(bar.isShowing()) {
           videoView = findViewById(R.id.v1);
           Uri uri = Uri.parse(path);
           videoView.setVideoURI(uri);
           videoView.start();
           ctlr = new MediaController(this);
           ctlr.setMediaPlayer(videoView);
           videoView.setMediaController(ctlr);
           videoView.requestFocus();
       }
        bar.dismiss();
    }
}
