Is it possible to play videos on Android with a native video player?

In one project the following code for Xamarin MediaManager works. But I have another project where I use the same code and there it is not working. The problem is that the video is not correctly displayed in full screen because there is a small free area between the video and the Android bar at the bottom of the screen in landscape mode.

In addition, the video view is not always removed from display after the video has played until the end. Sometimes customDialog.Cancel() is not executed.

I don´t want that the Android bar is displayed at the bottom of my tablet when a video is displayed.

I use SetImmersive() to remove the Android bar in my game but the problem is that the Android bar is displayed again when I start playing a video.

What can I do so that the Android bar is not displayed when I play a video?

Is it possible to use a native video player on Android instead of the Xamarin MediaManager? Maybe a native video player would work better.

    Hello,

    How can I hide this bar in my game when a video is playing?

    Firstly, you add Activity's Window to the Game1.s constructor. When you execute the ShowTheVideo method, you can hide the bar by windowInsetsController.Hide(WindowInsetsCompat.Type.NavigationBars()); windowInsetsController.SystemBarsBehavior = WindowInsetsControllerCompat.BehaviorShowTransientBarsBySwipe;

    You can refer to the following code, If the video is finished, this bar will show again. If you want to full screen, please move code about showing system bars in the MediaItemFinished event.

        public class Game1 : Game
        {
            private GraphicsDeviceManager _graphics;
            private SpriteBatch _spriteBatch;
            private Activity1 activity1;
            private Window window;
     
        
     
            public Game1(Activity1 activity1, Window window) 
            {
                this.window = window;
     
                this.activity1 = activity1;
                _graphics = new GraphicsDeviceManager(this);
                Content.RootDirectory = "Content";
                
            }
    
    public async void ShowTheVideo()
    {
     
         VideoDialog customDialog = new VideoDialog(activity1);
         customDialog.SetCancelable(false);
         customDialog.Show();
         await CrossMediaManager.Current.Play("https://sec.ch9.ms/ch9/5d93/a1eab4bf-3288-4faf-81c4-294402a85d93/XamarinShow_mid.mp4");
     
         // Hide system bars
         WindowCompat.SetDecorFitsSystemWindows(window, false);
         WindowInsetsControllerCompat windowInsetsController = new WindowInsetsControllerCompat(window, window.DecorView);
         windowInsetsController.Hide(WindowInsetsCompat.Type.NavigationBars());
         windowInsetsController.SystemBarsBehavior = WindowInsetsControllerCompat.BehaviorShowTransientBarsBySwipe;
     
         CrossMediaManager.Current.MediaItemFinished += (s, e) =>
         {
             customDialog.Cancel();
     
             // show system bars
             WindowCompat.SetDecorFitsSystemWindows(window, true);
             WindowInsetsControllerCompat windowInsetsController = new WindowInsetsControllerCompat(window, window.DecorView);             
             windowInsetsController.Show(WindowInsetsCompat.Type.NavigationBars());             
         };
    }
    

    In the end, if you init the Game1. Please add this.Window in _game = new Game1(this,this.Window); line.

      protected override void OnCreate(Bundle bundle)
      {
          base.OnCreate(bundle);
          CrossMediaManager.Current.Init(this);
          _game = new Game1(this,this.Window);
    ....
      }
    

    Best Regards,

    Leon Lu
