I would like to use Android's immersive mode in my Xamarin.Forms application, but I am facing problems with soft keyboard.
I already described my problem on StackOverflow, but I am hoping the more specific community here could help me 
I copy-pasted the question from SO, since I can't post links on here yet
"I am trying to get my Xamarin.Forms application to use Android's immersive mode, since I am using a device with small screen, so soft keys and navigation bar is stealing my precious screen real estate.
Since the device I am using features hardware keyboard, I wanted to hide the soft keyboard. Currently I solved this by installing a "Null Input Method" keyboard. The keyboard is still there however, so every time focus is requested on Entry element, the keyboard is "shown". This causes application to exit immersive mode. The same is true when I show an Alert from my forms application.
Ideally I would want my application to stay in immersive mode all the time, at least when focus on Entry is requested (soft keyboard is not "shown" at all or immersive mode is not disabled when keyboard is "shown"). For Alerts I would like the application to reenter immersive mode when Alert is hidden. Currently I solved this by extending the Page class with custom DisplayAlert methos, which toggles immersive mode after DisplayAlert Task is completed."
Any advices will be gladly appreciated.
