Why doesn't VideoView work when developing for android?

Question

Java

Good time of the day.
I am developing an application for android and faced the need to implement video playback from the site (using a link to a video file with a size of up to 100 mb), but when creating a VideoView, both in the visual editor and programmatically, the video is not displayed.
Here is the code:

VideoView VideoPlayer = new VideoView(page.this);
VideoPlayer.setVideoURI(Uri.parse("http://mysite.ru/file.mp4"));
VideoPlayer.setVideoPath("http://mysite.ru/file.mp4");
VideoPlayer.setMediaController(new MediaController(page.this));
VideoPlayer.requestFocus(0);
VideoPlayer.start();
PageCont.addView(VideoPlayer);

And this piece is generally highlighted as an error: (without it, it also does not work)

VideoPlayer.setMediaController(new MediaController(page.this));

What could be the problem? Thank you.

How strange everything is with you! Have you tried to see what kind of error you have?

        videoView = (VideoView) findViewById(R.id.video_view);
        MediaController controls = new MediaController(this);
        controls.setAnchorView(videoView);
        videoView.setMediaController(controls);
        videoView.setVideoURI(Uri.parse(url));
        videoView.start();
    }

}
