I want a complete Android e-commerce application built from scratch. The core of the project is a clean, intuitive shopping experience that consumes my existing REST APIs, parses JSON responses efficiently, and presents products attractively through XML-based layouts. To succeed you’ll need to: • Hook the app to my REST endpoints for product listings, cart actions, checkout, and user accounts. • Structure all network calls responsibly, with solid error handling and graceful offline states. • Respect Android’s latest permission model when accessing camera, storage, or sensors; the app must never crash on denied permissions. • Keep UI components modular and reusable—Material Design guidelines are a must so the catalog, product detail, and checkout screens feel consistent and modern. • Implement secure token-based authentication and persist sessions locally without compromising user privacy. • Ship the full, well-documented Kotlin/Java source, a signed release APK, and a short README explaining build and deployment steps. This is primarily an E-commerce app, so flawless product browsing, smooth cart operations, and responsive checkout flow are non-negotiable. I’m comfortable iterating in milestones: product catalogue first, cart and payments next, polishing and optimisation last. I will review the code style, stability on a range of devices (API 24+), and adherence to the above acceptance criteria before marking each milestone complete. If you’re confident with Android Studio, Retrofit/Volley, Glide/Coil, and can write maintainable, well-commented code, I’d love to work with you.
