I’m ready to roll out a dedicated Android e-commerce app and need the full build—interface, logic, and secure email-based sign-up all wrapped into a polished APK. The core flow is straightforward: browse products, add to cart, check out, and let users manage their orders from a personal dashboard. Only email/password authentication is required, so include account creation, sign-in, password reset, and session handling with best-practice security measures (JWT/Firebase Auth or an equivalent). Because the project is Android-only, lean on native components in Kotlin or Java and follow current Material guidelines so the UI feels modern and smooth. To keep things tidy, I’ll review progress in a Git repo. Please structure the code cleanly (MVVM or similar), comment critical sections, and add basic unit tests where business logic warrants. Once the build is stable, supply the signed release APK and all source files so I can push to Google Play without extra prep.
