Where is the best place to implement my geofence method?

[Jared Snyder]

I have created a method that builds a geofence based on the marker location. I am trying to determine where the best place to insert it is, so that it is specifically linked to the marker's location. Any thoughts?

private void buildGeofence(){
		long NEVER_EXPIRE = -1;
		int GEOFENCE_TRANSITION_ENTER = 1;
		LatLng geofencePoint = marker.getPosition();
		int radius = 1610;
		String requestId = "destination";
		Geofence.Builder geofence = new Geofence.Builder();
		geofence.setCircularRegion(geofencePoint.latitude,geofencePoint.longitude, radius);
		geofence.setRequestId(requestId);
		geofence.setExpirationDuration(NEVER_EXPIRE);
		geofence.setTransitionTypes(GEOFENCE_TRANSITION_ENTER);
		geofence.setNotificationResponsiveness(0);
		geofence.build();
		CircleOptions circleOptions = new CircleOptions();
		circleOptions.center(geofencePoint);
		circleOptions.radius(radius);
		circleOptions.strokeColor(Color.BLACK);
		circleOptions.fillColor(0x30ff0000);
        circleOptions.strokeWidth(2);
        map.addCircle(circleOptions);
		
	}

What do you mean by "where" - in the code? on the map? I'd say it depends on what the app does - does it make sense to create the fence when the marker is created, or should it be created later on as the result of some user interaction?

[Jared Snyder]

The geofence should be created once a marker is placed, and updated if the marker is moved. The monitoring of that fence will commence upon a user interaction, which is the pressing of a toggle button.

I'm thinking that I might do the monitoring code as a separate class.

[Ulf Dittmer]

So you need to build the fence as soon as the marker is set, and put some listener in place that alerts you if the marker is moved - and update the fence accordingly. That sounds relatively straightforward to me (although I have no idea about the fence APIs).

"Monitoring" sounds like adding a listener of some kind to the fence.

I've solved this one. I ended up overhauling all of my code related to this. I can't post my code, because it is integrated throughout my MainActivity and a couple other activities, but I will say that I referred to these sites for help:
