[android-developers] Re: ($25 reward) GPS not triggering onLocationChanged

I'll try the time zone problem.

The reason I used your WakefulIntentService was just to make sure the
application stays awake, I'm going to remove this now as it is working
just as well as a regular service. This service is started from
another service, which was triggered by an alarm. In regards to you
underground issue, it's a not a problem. The service that starts this
service will call the stopSelf method after 20 seconds, which is more
than the 13 seconds it waits for a location.
