First off, I think it should be known that I have zero experience with In-App Billing, so please go easy on the terminology and explanations :D
It's pretty unanimous that the In-App Billing part of the docs are among the worst documented parts of Android. The tutorial is spoken by someone who can barely speak any English and the docs tell me to write 60+ lines of code but do not say where. That said, I was recommended by most people to use this library:
https://github.com/anjlab/android-inapp-billing-v3
But before I use it, I have a few questions on logic...
1) I am currently blocking access to some content via boolean, I want to set boolean == true if they've purchased the content which then allows them access, is this an ok way to do it?
2) As you can see in the onPurchasedHistory() method, this saves their purchases, for this would I just put boolean == true and if not, how would I save their purchases?
3) Is there any guide to this documentation? It's obviously documented but I do not know which methods are optional or mandatory. Any recommendations (to this library)?
