Overview

PloxTools: Google Play Billing provides native Google Play Billing integration for Unreal Engine projects on Android.

The plugin exposes a complete Blueprint and C++ API for selling one-time products and subscriptions through Google Play.

It supports the following features:

  • One-time products
  • Subscriptions
  • Product details and localized prices
  • Subscription base plans and offers
  • One-time product offers
  • Consumable and non-consumable products
  • Automatic purchase processing
  • Manual acknowledgement and consumption
  • Pending purchase recovery
  • Owned purchase queries
  • Subscription status checks
  • Google Play in-app messages
  • Billing feature availability checks

The plugin provides an automatic purchase flow for common use cases. Consumable products can be consumed automatically after purchase, while products marked as non-consumable remain owned by the user.

A separate manual purchase flow is also available for projects that require full control over purchase acknowledgement, consumption, or server-side verification.

The plugin automatically integrates the required Google Play Billing libraries and Android manifest configuration into packaged projects. No Java or Android Studio integration is required.

Note

Google Play Billing is available only on Android. Billing functions do not operate on Windows or other target platforms.
