play-billing-library-version-upgrade

Migrate Android in-app purchases by replacing deprecated SkuDetails-based flows with modern ProductDetails-based async implementations. This process requires querying product details asynchronously, modernizing subscription configurations, and aligning purchase querying with current Google Play Billing policies.

Upgrading the Google Play Billing Library across multiple major versions requires a stepped migration plan, progressing two major versions at a time. This approach sequentially applies version-aware execution checklists derived from release notes to prevent compilation breaks before reaching the latest stable PBL.

Fix Google Play Billing compilation errors after a dependency upgrade by inferring the effective billing baseline. If builds fail, scan the project for deprecated billing artifacts like legacy SkuDetails usage to identify the actual API version and generate a targeted refactoring checklist.

Yes, the Play Billing Library migration explicitly addresses manual billing client reconnection and older purchase querying patterns. It refactors these legacy implementations into modern, async, and policy-compliant connection management and purchase flows required by the latest stable library.

A stepped migration plan for Android subscriptions is needed when the major-version distance exceeds two. Instead of a direct upgrade, you sequentially upgrade two majors at a time, applying version-aware checklists and verification routines to ensure subscription modernization remains stable.

After completing a Google Play Billing Library version upgrade, run a final validation build and test routine. This verifies that the codebase successfully compiles and that the modernized async purchase flows, connection management, and subscription querying operate correctly.
