Billingz

This is an opinionated, but convenient library for implementing Android's Google Play Billing Library and/or Amazon Appstore's In-App Purchasing API. Through a combination of Adapter and Facade design patterns, this library allows a project to integrate both billing libraries without explicit references to either, reduces the amount of needed code for integration, and speeds up development environments.

• Supports Android's LiveData and Lifecycle components
• Supports Kotlin Coroutines and Flow

Currently supports up to:

• google billing: 7.0.0
• amazon in-app: 2.0.76 (v2.0.6)
• amazon appstore sdk: 3.0.4 (v2.1.0+)
