Convert React Web App to Native Android App

I have an existing React web app (built on Base44).
I need it converted into a proper Android app built in Android Studio.

Scope:
- Wrap existing React app using Capacitor (or equivalent)
- Android Studio project setup
- Proper app icon, splash screen
- Native Google Play Billing integration (subscriptions + free trial)
- On successful purchase, unlock premium access via backend flag
- Build signed AAB ready for Google Play Console

Important:
- This is NOT a rewrite
- This is NOT Flutter-only
- React + Android Studio experience required
- Google Play Billing experience REQUIRED

Please show:
- Previous Android apps published
- Experience with Google Play subscriptions
