For this Android app, I’d structure the in-app purchase flow so every paid service is verified server-side before entitlement is granted, rather than trusting the device purchase state alone. I’d recommend native Android development with Kotlin/Jetpack Compose, Google Play Billing for purchases, and a secure backend for receipt validation, entitlement tracking, purchase restoration, and service fulfilment. The two priorities would be integrations and maintainability: purchase states, cancellations, refunds, and restored purchases need to stay synchronized, while multilingual content should be separated cleanly so new languages can be added without changing application logic. That reduces fraud risk and makes future expansion much easier. I can handle the Android app, backend APIs, authentication, purchase verification, localization structure, testing, Play Store readiness, and deployment end to end. A relevant project is Moholla, a multi-app commerce ecosystem with customer, shop-owner, and driver applications deployed on both Play Store and App Store, supporting real operational workflows across multiple user types.

Hi, Ankit here. I understand you need an Android app built around in app purchases, where users unlock services, plus full multi language support, and a backend that fulfils each purchase after Google confirms it. What usually matters most here is the purchase fulfilment backend, since Google Play only tells you a payment succeeded, and what the user actually gets depends on your server acknowledging and delivering the entitlement correctly. A common issue in IAP apps is that purchases are validated on the device, so when the app is reinstalled or the user switches phones, the entitlement is lost and support tickets pile up. The tricky part is combining Play Billing with server side verification and restore, while also handling multi language content cleanly, since translating the UI is easy but translating receipts and support flows is where most apps fall apart. My approach would be Kotlin with Play Billing, a small backend that verifies the purchase token against Google, stores entitlements per user, and serves translated content. Do you have a backend, or should that be included? Looking forward to hearing from you.
