What problem does it solve?

It solves the problem of breaking changes when upgrading Play Billing Library (PBL) by guiding a developer through a version-aware, checklist-driven migration from their current effective billing API level to the latest stable release.

Core Features & Use Cases

• Effective version detection: Detects your baseline using build config plus fallback scanning for deprecated artifacts (e.g., SkuDetails presence).
• Direct or stepped migration planning: Chooses a direct path if you are within two major versions, otherwise migrates two major versions at a time.
• Version-specific refactoring: Applies required code changes for reconnection handling, ProductDetails querying, subscription modernization, purchase querying, pending purchase rules, and SDK/compile/min SDK alignment.
• Verification and final validation: Runs build/sync/test/clean checks and validates version-specific requirements with a smart checklist.

Quick Start

Ask the assistant to run an end-to-end Play Billing Library version upgrade for your Android project to the latest stable PBL version, including detection of your effective current version, the appropriate migration path, the required code refactors, and the verification commands.
