Offline-first field service app for Android
A native Android app for technicians to receive jobs, capture readings and photos, and close work orders even without a network connection.
Problem
01 — OverviewTechnicians filled in paper job sheets on site, often in basements and plant rooms with no signal, and the office re-typed them days later.
Let technicians complete every job on the phone, offline if needed, and have the data reach the office as soon as a connection returns.
Solution
02 — Build- 01
Jobs, checklists and asset history are stored on the device, so the app works fully offline.
- 02
WorkManager syncs completed jobs in the background and resolves conflicts with the server by record version.
- 03
ML Kit text recognition reads meter values and serial numbers from the camera, so they are not typed by hand.
- 04
The customer signs on screen, and a PDF job report is generated and emailed on sync.
