VideoView: how to always show MediaController while playing video

Question

I have a very simple task - just to show playback controls while playing video on VideoView. But I can't solve it.

Here is the piece of code that I use for initializing VideoView and setting MediaController:

videoView.setVideoURI(Uri.parse(videoUrl));
MediaController mediaController = new MediaController(this);
videoView.setMediaController(mediaController);
videoView.setKeepScreenOn(true);
videoView.setOnPreparedListener(mp -> {
    progress.setVisibility(View.GONE);
    videoView.start();
    mediaController.show(0);
});

The thing is that mediaController.show(0) doesn't give any effect. Controls just show up for 3 seconds and then disappear.

Also I have tried to override MediaController's hide() method:

@Override public void hide() {}

Well, it works - controls never hide, but unfortunately hardware 'back' button stops working. Without override hardware 'back' button on first tap close media controls, on second tap - brings user to previous screen, as expected.

Are there any working solutions?

If you try to display media controler buttons as below :

    videoView.start();
    mediaController.show(0);

for some reasons show(0) is ignored.

But if you delay the call of show(0) a few milliseconds, it will work :

....
public Handler handler = new Handler();
....
videoView.start();
handler.postDelayed(
            new Runnable() {
                public void run() {
                    mediaController.show(0);
                }},
            100);

It looks a bit buggy to me and if it is design intent, it is poorly documentated.
