Hello, I have 10 years of experience developing Android and iOS applications, and I can build your native Android application from scratch through Play Store-ready deployment. I recommend Kotlin with modern Android SDK components for a clean, maintainable native architecture. I would implement secure authentication, Firebase Cloud Messaging for reliable push notifications, and Google Play Billing with proper purchase verification and handling of purchase states. The project will be structured with clean architecture, secure coding practices, clear separation of concerns, and well-documented code so future developers can easily maintain it. I’ll also validate the complete flow with internal testing before final handover. I’d be happy to discuss the implementation and timeline. Best regards

I see you're looking to build a native Android app with secure user authentication, push notifications, and in-app purchases. I can set this up using Android Studio with either Kotlin or Java, focusing on Firebase Cloud Messaging for those notifications and Google Play Billing for purchases. And I'll make sure the code is clean and well-commented for future developers too. I can have the app ready for you to test before any payment or award, you can check the functionality—creating an account, receiving a test notification, and executing a test purchase—before deciding to proceed. This way, you only pay when you're satisfied with everything. So, I'm ready to start immediately. Rajavel - Android Developer specializing in Kotlin, Java, and Firebase. I can go ahead and get to work as soon as you decide!

@adilmalikdev

Hi, I can build your native Android app from scratch using Kotlin and Android Studio. I’ll implement secure authentication, Firebase Cloud Messaging push notifications, and Google Play Billing. I’ll provide a clean, organized codebase with proper structure and clear comments for easy maintenance. You’ll receive a tested APK/AAB, complete Git repository, and a concise setup README. I’ll verify account creation, test push notifications, and sandbox purchases before final delivery. I can start immediately and take the app through internal testing to a Play Store–ready release.

@shayankhan333

Native Kotlin is the faster route here since FCM and Play Billing both have first-class Kotlin libraries. I'll build the auth flow, wire FCM for push, and integrate Play Billing, then ship a signed AAB with a Git repo and README. Play Billing sandbox only returns real responses once the signed AAB is live on the internal testing track and testers are added by email, so that gets set up early. I can pick this up straight away. 1) Which auth providers, email, Google, or both? 2) One-time products, subscriptions, or both? Cheers Shayan
