如何实施新的Google Play服务（分析）？

Question

I don't know exactly how to implement the new GPS Analytics into my app. My problem is located at the 4th step being described here . I dont know how to use

Tracker t = ((AnalyticsSampleApp) getActivity().getApplication()).getTracker(
            TrackerName.APP_TRACKER);

correctly. More exactly what do I need to write for AnalyticsSampleApp .

My Apps package name is com.mnd.tsst

My global_tracker.xml:

<?xml version="1.0" encoding="utf-8"?>

300

<!-- Enable automatic Activity measurement -->
<bool name="ga_autoActivityTracking">true</bool>

<!-- The screen names that will appear in reports -->
<screenName name="com.google.android.gms.analytics.samples.mobileplayground.ScreenviewFragment">
    TimetableApp TimeTableView
</screenName>
<!--  The following value should be replaced with correct property id. -->
<string name="ga_trackingId">UA-xxxxxx-5</string>

I entered a correct property ID, just removed it to show it here.

You need to create a new class that extends Application class with any name you want (say, MyApp )

In this class you have to add the methods and fields as suggested in the guide to be added to Application class.

public class MyApp extends Application {
    public enum TrackerName {
        APP_TRACKER,
        GLOBAL_TRACKER,
        E_COMMERCE_TRACKER,
    }

    HashMap<TrackerName, Tracker> mTrackers = new HashMap<TrackerName, 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);
    }
}

Also, add the following in the application tag of your manifest:

android:name=".MyApp"

where MyApp is the name you have given to your Application class.

In the global_tracker.xml file, I have yet understand the purpose of screenName , but however, for the time being, you should at least modify the sample package address to package name of your own Activities.

Now, let's say to send a screen view to Analytics, you would simply type anywhere inside any activity (maybe in onCreate or onResume):

Tracker t = ((MyApp) getApplication()).getTracker(
                        TrackerName.APP_TRACKER);       // Get tracker.
t.setScreenName(ACTIVITY_NAME);     // Pass a String representing the screen name.
t.send(new HitBuilders.AppViewBuilder().build());       // Send a screen view.

Similarly, to send an event (maybe from onClick of some button)

Tracker t = ((MyApp) getActivity().getApplication()).getTracker(
                    TrackerName.APP_TRACKER);
t.send(new HitBuilders.EventBuilder()
 .setCategory(categoryString)
 .setAction(actionString)
 .setLabel(labelString)
 .build());

This should give you a head-start.
