# Class Location

java.lang.Object
com.codename1.location.Location

public class Location extends Object

Represents a position and possible velocity returned from positioning API's. This class is used both by foreground and background location for the purposes of both conveying the users location and conveying a desired location e.g. in the case of geofencing where we can define a location that would trigger the callback.

Trivial one time usage of location data can look like this sample:

    Location position = LocationManager.getLocationManager().getCurrentLocationSync();

You can also track location in the foreground using API calls like this:

    public MyListener implements LocationListener {
        public void locationUpdated(Location location) {
            // update UI etc.
        }

        public void providerStateChanged(int newState) {
            // handle status changes/errors appropriately
        }
    }
    LocationManager.getLocationManager().setLocationListener(new MyListener());

The sample below demonstrates the usage of the background geofencing API:

    // File: GeofenceListenerImpl.java
    public class GeofenceListenerImpl implements GeofenceListener {
    @Override
        public void onExit(String id) {
        }
    @Override
        public void onEntered(String id) {
            if(!Display.getInstance().isMinimized()) {
                Display.getInstance().callSerially(() -> {
                    Dialog.show("Welcome", "Thanks for arriving", "OK", null);
                });
            } else {
                LocalNotification ln = new LocalNotification();
                ln.setId("LnMessage");
                ln.setAlertTitle("Welcome");
                ln.setAlertBody("Thanks for arriving!");
                Display.getInstance().scheduleLocalNotification(ln, System.currentTimeMillis() + 10, LocalNotification.REPEAT_NONE);
            }
        }
    }

    // File: GeofenceSample.java
    Geofence gf = new Geofence("test", loc, 100, 100000);
    LocationManager.getLocationManager().addGeoFencing(GeofenceListenerImpl.class, gf);
