Network Location unbundling:

The network location and geocode provider services are now started on demand and their interfaces are now retrieved via bindService(). Remove obsolete LocationManager installLocationProvider() and installGeocodeProvider() methods. Add abstract class android.location.provider.GeocodeProvider to provide a public wrapper to the IGeocodeProvider Binder interface. Replaces the LocationManager.GeocodeProvider interface. Rename LocationProviderImpl to android.location.provider.LocationProvider. Move LocationManager.reportLocation() to android.location.provider.LocationProvider, so all methods related to external location providers are now all in one class. Avoid calling from the Location Manager Service into providers that are disabled so we do not start the network location service unnecessarily.
