Geofence bugs often hide at the edge. A repeatable route lets you approach the same boundary at the same speed, cross at the same waypoint and compare event timing across builds.
Use responsiblyFlashGo includes developer testing among its stated uses. Receiving apps can detect or reject mocked locations; follow applicable laws and third-party terms.
Design three boundary points
- Outside: beyond the geofence radius and expected device uncertainty.
- Edge: one point just inside and another just outside the configured radius.
- Inside: far enough within the region to remove ambiguity.
Run the scenario
- Start well outside the fence.
- Move toward it at a fixed speed.
- Record the first entry event after crossing.
- Continue out of the region and record exit timing.
- Repeat with a slightly different edge waypoint and a screen-off interval.
Interpret results carefully
Geofence delivery can depend on permissions, background policy, Play services and batching—not just the coordinate. Log raw positions, reported accuracy and timestamps beside the geofence callbacks.
Common questions
Can I test a geofence without travelling?
Yes. A mock route can supply controlled coordinates to an authorized test app.
Why did the event arrive late?
Background limits, batching, reported accuracy and implementation details can delay callbacks. Inspect logs before changing the route.
