It's not clear from the documentation, but it looks like this function does 2 different things:
1. sets the device to use (or disable) the GNSS chip with the given options (i.e: GPS Only vs Multi system, etc)
2. the above + sets the callback for position events
I know there is a general confusion about how to disable GNSS, and some examples pass the method(:onPosition) even there, though it was confirmed by Garmin that it's not used when options is LOCATION_DISABLE, so it makes more sense to pass null for the callback.
class HikerApp extends App.AppBase { function onStart(state as Dictionary?) as Void { Position.enableLocationEvents(Position.LOCATION_CONTINUOUS, method(:onPosition)); } function onPosition(info as Position.Info) as Void { } function onStop(state) { Position.enableLocationEvents(Position.LOCATION_DISABLE, null); } }
Position.enableLocationEvents(Position.LOCATION_CONTINUOUS, null);
