B4A Library Licensing library

Ok so if we no longer need the license library how do we check things like annual subscriptions please?

Search "In-App Billing"

According to Google documentation it is indeed not required for API 16+.

Without the licensing library for api 16+, how do I be certain that someone is indeed a paying user before I grant him/her access to my app?

Google is applying a similar protection to all apps automatically. The app is encrypted and (theoretically) cannot be copied to other devices. It can only be downloaded directly from Google Play.
