I need a complete, production-ready Android food delivery application built from the ground up. The app must cover every step of a typical order flow: • Secure user registration and login • Real-time order tracking from kitchen to doorstep • Integrated payment gateway for card and wallet checkouts • Push notifications that keep customers informed at each stage • In-app messaging so buyers and couriers can communicate without leaving the app • A ratings & reviews section to capture feedback after every delivery I will supply brand assets, menu data and any required API endpoints for restaurants or logistics once development starts. You’ll handle coding, UI/UX, and basic QA, delivering both the signed APK and full readable source (Android Studio project). When these items compile and run smoothly on current Android versions and the listed features work end-to-end, the project is complete.
