Android Studio Developer Needed: Dynamic In-App Purchases (IAP) & Play Store Screenshots

Hi, I have a fully functional Android game built in Android Studio (Java/Kotlin). I need an experienced Android developer to integrate Google Play In-App Purchases (IAP), design a 9-item coin store, and create 6 Play Store screenshots. Key Responsibilities: In-App Purchase Integration: Integrate the latest Google Play Billing Library into the existing Android Studio project. Dynamic Store UI: Create an in-game store featuring 9 coin purchase options/packages. Dynamic Currency & Pricing: Product prices must NOT be hardcoded in the code. Prices must fetch dynamically from the Google Play Console based on the user's region and local currency. App Store Screenshots: Prepare 6 clean, attractive Play Store screenshots for the listing. Deliverables: Tested, clean source code (ZIP) + updated APK/AAB build ready for Play Console upload. Prerequisites: I will provide the complete source code. You only need to add the Billing Library logic, store UI, and generate the screenshots. If you have experience with Google Play Billing integration in native Android Studio apps, please send your proposal along with examples of previous work.
