I need a straightforward Android application that lets our warehouse team pull up any customer order, change its status in real-time, and push that update back to our existing distribution system. All activity will happen inside the four walls of the warehouse, so the interface can stay utilitarian: a compact order list, a detail screen for status changes, and a quick search field to locate orders by number or customer name. Core scope • Build a clean Android (native Kotlin or Flutter/Dart are both fine) app that installs from a single APK—no store release needed. • Authenticate users against our in-house API, fetch today’s assigned orders, and display their current status. • Allow the picker to tap and move an order through preset states such as “Picked”, “Packed”, and “Ready for Dispatch”, then send the update back via REST or GraphQL (whichever you prefer; we already expose both). • Cache data locally when the Wi-Fi drops and sync automatically once connectivity returns. • Supply well-commented source code plus a one-page setup note so my internal IT can re-build for future versions. Nice to have (not mandatory, yet keep in mind for extensibility): inventory count look-ups and basic barcode scanning hooks using the device camera. I’ll handle endpoint credentials and UX mock-ups; you focus on rock-solid Android development, testing on typical warehouse devices (Android 10+). Once delivered, we’ll run a short UAT cycle before sign-off.
