Just wanted to add that when working on both iOS and Android apps for enterprise clients, and they want to use the same design for both apps, there will still always be a difference because typically an Android business app should not have a Back button. Android users expect the hardware back button to serve that function, and they use it automatically. So generally, as far as my experience goes, a Back button is not expected in an Android UI.
I’ve built a stack based implementation for a game I did and the back button popped scenes off the stack. It really wasn’t hard to implement. My logic is if there is an overlay showing, hide the overlay. If I care, I’ll build the stack system, but in most cases, its simply go to the menu/home screen and then exit.

Thank you SO much guys for the great info! Giving your feedback, I decided to forget about it for now. Plenty of others issues to deal with when converting an ios app to Android/Amazon! making good progress with the help of the community. THANK YOU:)
