Starts location service updates. Last location coordinates could be.
Retrieved via Input.location.lastData. Service does not start to send location data immediately. Code should check Input.location.status for current service status. desiredAccuracyInMeters - desired service accuracy in meters. Using higher value like 500 usually does not require to turn GPS chip on and thus saves battery power. Values like 5-10 could be used for getting best accuracy. Default value is 10 meters. updateDistanceInMeters - the minimum distance (measured in meters) a device must move laterally before Input.location property is updated. Higher values like 500 imply less overhead. Default is 10 meters.
