When the LocationManager has a new location to offer, it makes a call to onLocationChanged() for each listener. ” Receiving Location Updates with a Broadcast Intent Having an Intent broadcasted with location updates can offer increased ﬂexibility in situations where an app needs the update to be received by multiple application components. To make use of the broadcasted Intent, an app needs to implement a BroadcastReceiver and register it to receive location update Intent(s). This can happen either in an Android manifest or at run time.
