I believe that's correct. Someone more familiar with Android may know better; @jonahwilliams, are you familiar with this part of Android?

I believe these are the correct configurations - though it might be worth mentioning somewhere that you almost never want android to restart the activity for a flutter application. Especially since this goes directly against the advice of the Android documentation. So supporting split screen, for example, requires you to add screenLayout and probably density too.

Please review, @jonahwilliams @willlarche

I found a number of things that needed correcting, and also need to fix up the language. Jonah, I added your excellent note about not restarting a Flutter activity from Android. And, Will, I migrated some of your recently added text to the Android page.

LGTM!
