          GLOBAL_TRACKER, // Tracker used by all the apps from a company. eg: roll-up tracking.

            GoogleAnalytics analytics = GoogleAnalytics.getInstance(this);
            Tracker t = (trackerId == TrackerName.APP_TRACKER) ? analytics.newTracker(PROPERTY_ID)
                : (trackerId == TrackerName.GLOBAL_TRACKER) ? analytics.newTracker(R.xml.global_tracker)
                    : analytics.newTracker(R.xml.ecommerce_tracker);
