I integrated the Google Analytics Tracker.
I used the following code to send a track for the welcome screen:
   Tracker tracker = ((AnalyticsSampleApp) this.getApplication()).getTracker(
            AnalyticsSampleApp.TrackerName.APP_TRACKER);
    // Enable Advertising Features.
    tracker.enableAdvertisingIdCollection(true);
    // Set screen name.
    tracker.setScreenName("Welcome Page.");
    // Send a screen view.
    tracker.send(new HitBuilders.AppViewBuilder().build());
How can I know if tracking is working.

For true end-to-end testing create your own Google Analytics account and hard-code your own property ID. The real-time dashboards will show you your test activity.
