When I refer to Android screen I usually use two words “page” and “screen”. This page word probably remained from the web development.
Now, when I want do display a Toast message to a user, should I say something like “You are currently on this page” or “You are currently on this screen”?
I wouldn’t write “page” because page just belongs to the web development in my opinion. So you could choose “screen” or just take another sentence like “You currently see …”, “What you see here…”
This is what I think but you display a Toast it could be that the user doesn’t read it.
