Why is mock location jumping back to real position

问题


I added a test provider using LocationManager.GPS_PROVIDER as provider name like described here

In Google Maps app, I see location jumping between mocked location and real location, and then back to mocked location.

Why is jumping to real location and how can I stop it?

Maybe I misunderstand how to use mock locations. I haven't found any official documentation available.

You most likely have your location settings configured in a way that your phone (and apps) can use both the location from the GPS sensor and the location from the cells and wi-fi. Since the coming of the Fused Location Provider, the way the system fetches your location got a bit murkier.

When you mock the position you are only able to mock the GPS sensor readings (this is also true for when you mock the position through the simulator settings). So when the system feeds Google Maps with a position from the GPS sensor it gives it the fake one, and when it provides the position from other sensors it will be the real one.

To test that I'm correct, you can switch location settings to "Device only" and you should only get the fake positions.

Unfortunately there's no way to mock the other sensors readings.
