I’m wondering how can I add IAP for stores that are not Google Play, for example, If i submit my app to Samsung Apps, should i still be able to make IAP through Google Play even if the game was NOT downloaded from the Play Store? Can I distribute my game’s APK just by itself and still be able to collect money from IAP using Google Play store? I can see when you build an app you can select a target store, and you can target Samsung, is it a special kind of store (different method to sell IAP)? or do I use the same code to IAP as in Google Play?
I know, Lots of questions! but I need to know!
TL;DR: Can I use Google Play to make IAP on a independent distributed APK?
