Android Order Status Entry App

I need a straightforward Android-only application that lets me record the daily status of each customer order while I’m on the go. The core flow is simple: open the app, pick or type an Order ID, choose a status (for example Pending, Shipped, Delivered, Cancelled), add an optional note, then hit Save. I should be able to review and edit past entries just as easily. Because this will be used every day, the interface has to load fast, work smoothly on recent Android versions, and stay usable even when the device is temporarily offline—queued entries can sync once a connection returns. Feel free to recommend a light, reliable backend (SQLite, Firebase, or another option you trust); I’m flexible as long as the data is stored safely and can be exported later. Deliverables • Android Studio project with well-commented source code • Signed APK ready for installation • Brief setup / user guide (PDF or Markdown) I don’t have a strict deadline, so we can focus on clean code, clear documentation, and a UI that makes daily entry effortless.
