Hello, I can upgrade your Java-based Android app to fully support Android 15 (API 35) while maintaining compatibility from Android 8 upwards. I have handled similar SDK migrations and understand the nuances of updating stable production apps without breaking core functionality. Approach: Project Setup: Update Gradle files, build tools, dependencies, and target/compile SDK to 35. Ensure compatibility with the latest Android Studio. Code Refactor: Replace or adapt deprecated APIs (runtime permissions, notification channels, background execution limits, scoped storage, etc.). Library Updates: Verify and upgrade 3rd-party libraries and Google Play Services to stable versions compatible with API 35. Testing: Run tests on emulators and physical devices covering Android 8–15. Validate behavior against Google Play’s pre-launch requirements. Deliverables: Release-ready AAB, updated source code compiling with zero errors and minimal warnings, plus a concise changelog with notes on workarounds and items to monitor for future SDK updates. Experience: I’ve recently upgraded legacy Java apps to API 34 and 35, handling permission changes, notification updates, and storage transitions seamlessly. Timeline: Typically 1–2 weeks depending on library compatibility and scope of deprecated API usage. Best regards, Sumit Joshi
