I want an Android application that lets everyday users order their required quantity of milk, see their previous purchases, and follow the live delivery status—everything neatly packed in a clean, intuitive interface. On the other side of the same code-base, an admin area must allow me (or any staff member) to create and edit daily delivery slots, review and update every incoming order, and keep an eye on those orders as they move through the delivery workflow. Both roles—admin and customer—must sign in before they can do anything, so please include secure authentication flows for each . The end result I’m looking for is an Android Studio project that I can compile and publish, complete with source code, assets, and a concise setup guide. Acceptance criteria: • Users can place an order, browse order history, and see real-time status changes. • Admins can create time slots, edit or cancel them, view all orders, and update their status. • Authentication is enforced for both roles and persists across sessions. • UI/UX feels native on current Android versions and functions smoothly on phones and small tablets. If you have experience with Kotlin/Java, Firebase, or similar back-end integrations and can deliver a polished, production-ready build, I’d love to work with you.
