You’re close, but intermittent geofence triggers are a known pain point in Android due to a mix of power optimizations, background restrictions, and subtle lifecycle issues. Here are 10 critical checks and recommendations to ensure your geofencing is more reliable:

Location Request Frequency

You’re not actively requesting LocationUpdates — that’s fine for geofence-only logic. But adding a passive location request can help keep Play Services “warm” and improve accuracy:

val request = LocationRequest.create().apply {
    priority = LocationRequest.PRIORITY_HIGH_ACCURACY
    interval = 10_000
}
fusedLocationClient.requestLocationUpdates(request, locationCallback, Looper.getMainLooper())

Debounce Duplicate Registrations

Calling addGeofences() multiple times with same requestId or without calling removeGeofences() first can make things flaky.

Consider clearing old geofences before re-registering:

geofencingClient.removeGeofences(geofencePendingIntent).addOnCompleteListener {
    addGeofenceRequest()
}
