## What it is
A lightweight Java wrapper around Google Play Billing Library 9.x for Android, supporting in-app product purchases (consumable and non-consumable) and subscriptions. It simplifies the Play Billing API with a straightforward BillingProcessor callback interface.

## Use cases
- add in-app purchases to an android app
- implement subscription billing on google play
- sell consumable products in my android app
- simplify google play billing integration
- handle one-time and recurring purchases in android

## When to choose
- you want a simple wrapper over Google Play Billing instead of the raw API
- you need both one-time purchases and subscriptions in an Android app
- you prefer a lightweight, well-established Java library on Maven Central

## When to avoid
- you need active maintainer support - the project is looking for new maintainers
- you need multi-offer subscription pricing phases or promotional offers - use the raw Play Billing ProductDetails API
- you target Android API 21-22 - minSdk is now 23
- you build with compileSdk below 35
