Fullscreen on Android

Android

Hi,
Just wanted to report something that looks like a bug for me.
I need to run my game in not fullscreen mode on androind (so status bar shouls be visible).Just setting IsFullScreen = false; looked good,

but I noticed that putting app into backround resets settings and when resumed bar disappears and game content moves up so there is an empty area (with heigh equal to bar heigh) at the bottom.

If to try reset IsFullScreen on app resume, it returns bar but actual game rendering rect still at the top with the same empty area at the bottom.

My workaround was to not set IsFullScreen = false but instead just to apply activity flags (Window.SetFlags(WindowManagerFlags.ForceNotFullscreen, WindowManagerFlags.ForceNotFullscreen)) on app start and resume. this allows me to always have bar visible, also needed to apply some top padding in my game logic. This works even better for me, but anyway I believe it’s something wrong with initial MonoGame behavior.

PS. I build libs from the latest dev github sources.

Thanks for the bug report. It has most likely been unnoticed for so long because so few people use IsFullScreen = false on Android.

And iOS seems to have bug too.

if to set IsFullScreen=false; in game constructor when graphicsdevice is not created yet, it will set value to local field “_wantFullScreen”
but then when

public override bool PrefersStatusBarHidden()
        {
            return _platform.Game.graphicsDeviceManager.IsFullScreen;
        }

it return value of _graphicsDevice.PresentationParameters.IsFullScreen which is not set and has default value (true).

I think that the fix is to set

_graphicsDevice.PresentationParameters.IsFullScreen = _wantFullScreen;

in ApplyChanges() of GraphicsDeviceManager. At least it works, but I didn’t make any investigations how it may influence other things.
