Make a paid version.

[RobertWarrenGilmore]

What features belong in the paid version? Am I allowed to sell the app (because of IP concerns?

[RobertWarrenGilmore]

How will the paid version be built? Can I set up Android Studio to build two versions, each one with a different value injected for some constant like IS_PAID_VERSION?

[RobertWarrenGilmore]

Can the flag be flipped without downloading a new package, by doing an in-app purchase? This is on a watch, so I don't know how an in-app purchase would work. I don't want to create a companion phone app.

How can I give the premium version out for free? I don't expect normal users to sideload APKs. I'd like to give them some kind of gift code to type into the Play store.

The paid version needs a distinct screen shot and icon.
