Let me know if you need any more info. Thank you
You are not passing any video URI to the VideoView, that's why it remains black.
Try by hard coding your video URL.
For example,
videoView.setMediaController(mediaController);
videoView.setVideoURI(Uri.parse("https://youtu.be/RkD_eAzSF7U"));
videoView.start();
And regarding DrawerLayout's black background, check the code of @layout/nav_header_main, may be its background color is black.
