Broadcast intent action when NoType:android/provider/Settings$Secure;Href=../../../reference/android/provider/Settings.Secure.html#LOCATION_MODE changes. For use with the NoType:android/provider/Settings$Secure;Href=../../../reference/android/provider/Settings.Secure.html#LOCATION_MODE API. If you're interacting with LocationManager.IsProviderEnabled(string), use LocationManager.ProvidersChangedAction instead. In the future, there may be mode changes that do not result in LocationManager.ProvidersChangedAction broadcasts.
