Im experimenting with flashbuilder 4.6 and am using this simple / bare-bones geolocation code I found online to do some testing as I try to learn more about it and how it might be used...
one thing I am curious to know is how to stop / interrupt the geolocation routine so that it STOPS polling for the location and waits for the user to 'start' the geolocation.
if I use clearInterval(interval); that can stop the loop I guess -- but geo2 continues to exist and use device resources, correct? what would the code look like to use a slideToggle to control it for example?
The geolocation code snippet Im experimenting with...
private function onMapReady(e:Event):void
{
if (Geolocation.isSupported)
{
var geo = new Geolocation();
geo.setRequestedUpdateInterval(100);
geo.addEventListener(GeolocationEvent.UPDATE, geolocationUpdateHandler);
}
else
{
trace("No geolocation support.");
}
}
private function geolocationUpdateHandler(event:GeolocationEvent):void
{
trace("lat:" + event.latitude.toString() + " - ");
trace("long:" + event.longitude.toString() + "° - ");
trace("Accuracy:" + event.horizontalAccuracy.toString() + " m");
}
If you want to stop reacting to polling updates, just remove the listener:
geo.removeEventListener(GeolocationEvent.UPDATE, geolocationUpdateHandler);
If you want to switch off polling completely, just nullify it:
geo = null;
(and make sure you also remove any listeners first)
