No Internet? No Problem!
summary
Off Grid Electric builds an Android app that keeps field agents working in 2G or airplane mode by storing data locally, queuing actions and syncing later; the architecture uses MVP pattern to separate UI and network, a local DB (Realm), a pub/sub layer (EventBus), and job queuing (Android-Job) to schedule retries. APIs include timestamps, status fields and bundled endpoints for deltas and conflict resolution. The system successfully lets agents complete orders offline, persist changes, and get notified when background syncs finish.
