Location Updates within a Service

Requesting location updates within a remote service may cause the following exception:

runException Can't create handler inside thread that has not called Looper.prepare()

The requestLocationUpdates() function requires access to a Looper to deal with messages in a queue. When calling this method in a background service, the method may not implicitly have access to the threads Looper. Defining the thread's Looper explicitly by adding an additional argument 'Looper.getMainLooper()' deals with the issue.

	locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 4000, 0, listener, Looper.getMainLooper());
