Hi,
The permissions and the settings are correct. I think it crashes if it
isn't.
I changed my function a bit such that the update request has a minimum
delay of 10 seconds and 10 meters. But I still get no updates. I can
get the last known location from the location manager so I figured
that works. Just the LocationListener's methods never gets called
somehow...
