        GoogleAnalyticsTracker tracker = new GoogleAnalyticsTracker(

        // attach the GA tracker to this UI

        Navigator n = new Navigator(this, this);
        n.addView("", MainView.class);
        n.addView("second", SecondView.class);
        n.addView("third", ThirdView.class);

        // attach the tracker to the Navigator to automatically track all views
        // To use the tracker without the Navigator, just call the
        // tracker.trackPageview(pageId) separately when tracking is needed.
        getNavigator().addViewChangeListener(tracker);

        // Alternatively you can use trackPageview
        tracker.trackPageview("/samplecode/init");
    }
