In my Android 10 phone, if I copy a piece of text that looks like an address and open Google Maps, Google Maps will immediately offer the copied text as a search option. Google Maps doesn't do this if I copied, say, some random numbers.

I'm not sure how the Google Maps app can do this without snooping at my clipboard.

Background clipboard access is already blocked on Android, except for direct entry apps such as keyboards.

Of course it's still possible to check the clipboard when the app receives focus, just like on iOS.
