Android Billing & Launch Support

My Kotlin-based Android app is feature-complete in GitHub and built with the Emergent framework. The last pieces missing are commercial: Google Play Billing, a clean RevenueCat back-end, and full shepherding through the Play Console until the store listing is live. What I already have • Source code stored in a public GitHub repo • Google Play developer account with app entry created • RevenueCat account waiting for its first project What I need from you 1. Set up Google Play Billing Library so both in-app purchases and subscriptions run smoothly in sandbox and production. 2. Configure my RevenueCat dashboard from scratch, wire it to the codebase, and make sure entitlements unlock correctly. 3. Test and troubleshoot the entire purchase flow end-to-end, fixing any edge-case errors that turn up. 4. Produce a signed AAB, upload it, clear pre-launch report issues, and guide me through the final “Publish” button. Imp note - current app development is with emergent Acceptance criteria – In-app purchases and subscriptions process successfully on a test track and reflect in RevenueCat analytics. – Play Console shows zero billing-related errors or warnings. – The listing is approved and visible to real users. – A short hand-off note explains how to swap billing providers later so the same codebase can become a webapp with minimal rework. Tools & tech that will likely come up: Android Studio, Play Console, GitHub Actions (optional for CI), Gradle, RevenueCat SDK, Google Play Billing Library v6. I’ll give you access to the repo and both dashboards. Let’s get this monetisation finished and the app live.
