play-billing-library-version-upgrade

To upgrade the Google Play Billing Library, calculate a direct or stepped migration path based on your app's effective PBL version, synthesize a checklist per major-version jump, and verify via Gradle builds and clean test validation.

A Play Billing dependency update causes compile failures when your project uses deprecated or removed APIs from older legacy versions. The Skill guides refactoring deprecated API usage while preserving existing subscription and one-time purchase behavior.

A stepped migration path for Google Play Billing is needed when your app is far behind the latest stable version. The Skill infers your effective API availability from source usage to determine if intermediate major-version jumps are required.

Yes, you can preserve subscription and one-time purchase behavior by applying intent-first reporting and documentation-driven checklist synthesis during the migration, ensuring functional continuity across PBL major versions.

The best way to verify a Play Billing Library upgrade is through end-to-end validation using Gradle builds, incremental environment alignment, and clean assemble and test steps to ensure no deprecated API usage remains.

Yes, the Google Play Billing Library upgrade process requires environment alignment. The Skill executes guardrailed refactoring by aligning your environment, running incremental builds, and validating clean test and assemble outputs.
