Google analytics android sdk 4 newTracker undefined

I've been looking through the documentation and resources on the Google Analytics site to implement it with Android SDK 4. I've gone through a few Stack Overflow posts, but others seem to have other issues. I followed the steps to initialize the tracker by creating a class that extends the application to configure the tracker as well as my e-commerce and global trackers.

In my application class, everything follows from the example, but the "newTracker" method is undefined. I have libGoogleAnalyticsServices.jar in my library and below is my class. Thanks for watching, I am very confused.

import java.util.HashMap;
import com.google.analytics.tracking.android.GoogleAnalytics;
import com.google.analytics.tracking.android.Tracker;

import android.app.Application;

public class GlobalState extends Application {
    private static final String PROPERTY_ID = "myNumber";
    private Tracker tracker;
    HashMap<TrackerName, Tracker> mTrackers = new HashMap<TrackerName, Tracker>();

    public enum TrackerName {
        APP_TRACKER,
        GLOBAL_TRACKER,
        E_COMMERCE_TRACKER,
    }


    synchronized Tracker getTracker(TrackerName trackerId) {

        if (!mTrackers.containsKey(trackerId)) {

            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);
        }
        return mTrackers.get(trackerId);
    }

      

        
        
        
      

    

}
