Android App with Auth & Purchases -- 2

Job ID: 40140372

Budget: $15 – $25 USD

I need a complete Android application built from the ground up. The core build must run smoothly on current Android versions and include three essential capabilities: secure user authentication (sign-up, login, password reset), timely push notifications, and fully integrated in-app purchases.

To keep the project maintainable, clean architecture and readable, well-commented code are priorities. You are welcome to choose the most efficient modern stack—if Firebase Authentication, Firebase Cloud Messaging, and Google Play Billing suit your approach, feel free to use them, but alternative libraries are fine as long as they deliver the same reliability.

Deliverables
• Production-ready APK and signed AAB
• Complete, documented source code in a Git repository
• Clear build/run instructions and a brief hand-over session so I can publish updates on my own

Once I can log in, receive a test notification, and successfully execute a test purchase on a sandbox account, the job will be considered finished.
