Challenge Task 4 of 4
Handle the Message in GeolocationService, and use the 'replyTo' property to send a new Message back to MainActivity with the latitude in 'arg1' and the longitude in 'arg2'.
Then call setCoordinates(int lat, int long) from within MainActivity to update the coordinates.

public class MainActivity extends Activity {
Boolean isBound = false;
Messenger mServiceMessenger;
Messenger mMessenger = new Messenger (new ActivityHandler());
ServiceConnection mServiceConnection = new ServiceConnection() {

isBound = true;
mServiceMessenger = new Messenger(binder);
if (mServiceMessenger != null) {
