Android : Error while integrating google analytics in android application

I am trying to integrate the google analytics in my android application and I am following this tutorial. Now I am getting error in this step. See the below code.

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);
      mTrackers.put(trackerId, t);

Here the newtracker before the bracket is always showing error. I don't know what to do.

Kindly, Help me to fix this.
