Introducing Google Play Billing Library 7: New Features and Migration Guide

Google Play Billing Library 7, introduced at the 2024 Google I/O, presents significant updates over previous versions with features like virtual installment subscriptions, allowing users to pay in smaller, manageable amounts, and support for pending transactions in pre-paid subscriptions. These changes aim to improve accessibility and subscription rates, though installment subscriptions are initially available only in select countries. Developers using older versions need to migrate due to deprecation schedules, with Play Billing Library 5 being deprecated by August 2024 and Library 6 by November 2025. Migration involves updating project dependencies and replacing deprecated APIs, with considerations for new error codes and API functionalities. RevenueCat's Android SDK already supports Play Billing Library 7, providing an integrated solution to handle these updates seamlessly, thus reducing development time and maintenance efforts.
