The getLastKnownLocation() only returns in my experience valid locations if
there is elsewhere something that has subscribed to location updates, with
something like this:
public void subscribeToLocationUpdates() {
this.lm =
(LocationManager)getSystemService(Context.LOCATION_SERVICE);
this.lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
}
The 'this' here is a class that also implements the LocationListener
interface.
I know this somehow does not make sense, but that is how I worked around
just getting nulls back.
