Architecting for Zero-Network Dependencies: Challenges in Offline-Only Geofencing

The article discusses the challenges of implementing offline-only geofencing, where devices must function independently of network dependencies. This is particularly important in sensitive environments like places of worship or medical clinics. To achieve this, the author built a system called Muffle, which uses native Google Play Services location library and custom logic to manage state transitions and AudioManager calls without network requests. This approach allows for reliable and context-aware device behavior even in areas with weak or no signal.
