public class NativeLocationSource
extends ContextualVehicleDataSource
implements android.location.LocationListener, java.lang.Runnable

Generate location measurements based on native GPS updates. This source listens for GPS location updates from the built-in Android location framework and passes them to the OpenXC vehicle measurement framework as if they originated from the vehicle. This source is useful to seamlessly use location in an application regardless of it the vehicle has built-in GPS. The ACCESS_FINE_LOCATION permission is required to use this source.
