How to make android start full screen display

[lmj888cool]

I am using stride4.1 to develop an android mobile game. I have tried to make the game display in full screen on the phone screen, but it cannot cover the bangs, so there is a black border on the top of the phone.I want the full screen to include the notch part. Is there any developer who is using stride4.1 to develop android that has solved this problem?

In your project's GameSettings, what version of OpenGL is your project set to?

Full disclosure, I haven't tested this but since there is overlap between a 'standard' android app & xamarin, this solution might work

protected override void OnCreate(Bundle? savedInstanceState)
{
    base.OnCreate(savedInstanceState);
    if (Build.VERSION.SdkInt >= global::Android.OS.BuildVersionCodes.R)
    {
        Window.SetDecorFitsSystemWindows(false);
    }
    else
    {
        StatusBarVisibility option = (StatusBarVisibility)SystemUiFlags.LayoutFullscreen | (StatusBarVisibility)SystemUiFlags.LayoutStable;
        Window.DecorView.SystemUiVisibility = option;
    }
    Window.AddFlags(WindowManagerFlags.DrawsSystemBarBackgrounds);
    Window.SetStatusBarColor(global::Android.Graphics.Color.Transparent);
}

Do tell if it works!

It can be displayed in full screen, but the status bar above and the navigation bar below are always displayed. If the API to hide the status bar and navigation bar is called, it cannot be displayed in full screen again. . .

Sorry, I'm not sure I understand the problem, however I think you are closer to finding a solution for your issue by playing around with the Window settings in the Activity class.
Maybe try the solution from this one?

If this solution doesn't work, you will probably have better luck just searching for solutions involving Android Xamarin or Android Monogame since they all involve the Activity class as the base class like in Stride, so there should be some overlap in the solution.
