I want to launch a native Android application that makes it easy for drivers to book on-demand car washing and cleaning. The build needs three distinct roles: • Customer – register or sign in, choose a wash or deep-clean package, set location, pick a time slot, and confirm payment; then receive push notifications as the service provider accepts, starts and completes the job. • Service Provider – get a real-time list of assigned bookings, update each step of the service, upload before/after photos if needed, and track daily earnings. • Admin – oversee user accounts, pricing, service categories, promo codes and a live dashboard of all current jobs. Core requirements – Android-only release, produced with Kotlin or Java; Flutter is fine if the APK runs smoothly on the full range of current devices. – Simple, modern UI that adapts to different screen sizes. – Secure login, Firebase or similar push notifications, and location integration for customer addresses. – Well-commented source code, build instructions and a signed APK at hand-off. Please include a brief outline of your proposed architecture, any similar apps you have shipped, and the timeline you’d need from wireframes to Google Play submission.
