Architecting reliable geofencing in Android without burning battery

Architecting reliable geofencing in Android without burning battery

Short summary

A developer shares lessons from building Muffle, an Android app that auto-manages sound profiles based on geofencing without draining battery. Key architectural decisions include using GeofencingClient instead of GPS polling, handling Doze mode with JobIntentService, and re-registering geofences after boot. The post also highlights cross-manufacturer GPS inconsistency as a major real-world challenge.

  • •Uses GeofencingClient for OS-level batched boundary checks instead of GPS polling
  • •Handles Doze mode, boot-completed re-registration, and loitering delays to prevent flickering
  • •Discusses OEM-specific battery management killing PendingIntents on mid-range devices
