Android location service updates are unreliable

I've only been able to test in the emulator, which has an interface for setting geolocation points; but using that UI doesn't seem to have any impact on the running app:
- It will return a GPS read in response to retrieving the current location; but if you use the "Single point" GUI to change the current location, the same (original) location is consistently returned
- The "Routes" UI lets you describe a driving path, but it doesn't seem to generate any location update events.
I'm unsure if this is me driving the emulator wrong, a bug in the emulator, or misuse of the geolocation APIs. If you're able to take this for a walk (literally), and/or let me know what I'm doing wrong with the emulator, that would be helpful.
I'm seeing the same thing on the default Briefcase emulator. But if I use Android Studio to create an "Android 14.0 (Google APIs)" image, which includes Google Maps, I find that Google Maps updates correctly. And when I switch back from Google Maps to Toga's example app, it updates its position, but then it doesn't update again until I switch to Google Maps again.
On my physical device (Pixel 7), I saw the same behavior at first. But then after the first time I opened Google Maps, the example app started working perfectly with no need to switch back and forth, even after restarting my phone.
