Example App 1: As simple as possible

Let's assume, you like to offer a free version of your app and a premium version. After paying a small amount, the user can upgrade to the premium version to get additional features. So there is only one product to buy. After successful purchase, store the status (premium) in TinyDB, so you also can get the correct status of the app (free or premium) also if there is no internet connection. You can test the example using the test product android.test.purchased also in the companion app.

If you want to test again, first consume the product and clear the tag premium in TinyDB.
