Geolocation changed event fires even when location not changed?

Bug Reports

I know some of you are getting tired of me already, but bare with me, I think this is the last hickup :slight_smile:

I have an changed handler that’s supposed to fire when the location is changed.

However, I have not changed the location in the emulator, and it fires like every 2 seconds or something…

Here’s the console.log of Date.now()

changed 1494352058914
changed 1494352059984
changed 1494352061070
changed 1494352062125
changed 1494352063137

The code is:

<App>
<JavaScript>
		var Observable = require("FuseJS/Observable");
        var GeoLocation = require("FuseJS/GeoLocation");

        var hikes = [{"Title":"This is a hike", "Description":"It's a very good hike","LocalPhoto":"Assets/screen2.png"}]
        var trails = [{"Title":"This is a trail", "Description":"It's a very good trail","LocalPhoto":"Assets/screen2.png", "Locations":[{"lat":"41.996075","lon":"21.431812"}]}]

        // Immediate

        var Tours = Observable();
        var timeoutLocation = Observable("");

        var isDialogShowing = Observable(false);

		function distance(lat1, lon1, lat2, lon2) 
		{
		  var R = 6371; // km
		  var dLat = toRad(lat2-lat1);
		  var dLon = toRad(lon2-lon1);
		  var lat1 = toRad(lat1);
		  var lat2 = toRad(lat2);

		  var a = Math.sin(dLat/2) * Math.sin(dLat/2) +
		    Math.sin(dLon/2) * Math.sin(dLon/2) * Math.cos(lat1) * Math.cos(lat2); 
		  var c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a)); 
		  var d = R * c;
		  return d * 1000;
		}

		// Converts numeric degrees to radians
		function toRad(Value) 
		{
		    return Value * Math.PI / 180;
		}

       function startContinuousListener() {
            var intervalMs = 1000;
            var desiredAccuracyInMeters = 10;
            GeoLocation.startListening(intervalMs, desiredAccuracyInMeters);
        }

        function stopContinuousListener() {
            GeoLocation.stopListening();
        }

        startContinuousListener()

        var observedLocation = GeoLocation.observe("changed");
        var mapLocation = observedLocation;

		GeoLocation.on("error", function(err){console.log(err)});
		GeoLocation.on("changed", function(loc){
			
			console.log(JSON.stringify(observedLocation))
			
			if (observedLocation.value){
				var dist = distance(41.995876, 21.431812, observedLocation.value.latitude, observedLocation.value.longitude)
				if ((dist < 50)){
					// Display modal
					isDialogShowing.value = true;
					console.log('check 1')
					console.log(isDialogShowing);
				}
			}
		});


		var mapLocation = observedLocation;
		var continuousLocation = observedLocation.map(JSON.stringify);

		function testToggleBool() {
			isDialogShowing.value = ! isDialogShowing.value;
		}


        module.exports = {
            timeoutLocation: continuousLocation,
            mapLocation: mapLocation,
            hikes: hikes,
            trails: trails,
            isDialogShowing: isDialogShowing,
            testToggleBool: testToggleBool
        };

    </JavaScript>

Why does this happen? It would be nice if this fires ONLY when the location is changed.
