Explicit fullscreen toggle (F key)

[markg85]

Hi,

In normal android usage you don't need this.

However, i'm trying to run this in Samsung Dex. It works wonderfully! Except the added Dex window decoration always stays in view. I'm not even entirely sure if this can be hidden with Android API calls but i think it can because there are explicit options to toggle fullscreen (like this).

I'm intentionally referring to the deprecated option as it describes how to do it.

I'll also try this on my end. If i get it working i'll submit a PR. Don't expect anything soon, i thoroughly hate android development. Especially java/kotlin and with that especially this project. Nothing against this project (it's awesome!) but my builds always take literal hours, fail many many times and then suddenly work just a few times before they start failing again. Yes, really! And that is on a clean environment. I don't know why. It just is.
