metaタグとpermissionを追加します。

public class AnalyticsApplication extends Application {
	
    private static final String PROPERTY_ID = "your property id";
    Tracker mTracker;

    public AnalyticsApplication() {
        super();
    }

    synchronized Tracker getTracker() {
        if (mTracker == null) {
            GoogleAnalytics analytics = GoogleAnalytics.getInstance(this);
            mTracker = analytics.newTracker(PROPERTY_ID);
        }
        return mTracker;
    }
}

@param categoryId カテゴリ
@param actionId アクション
@param labelId ラベル

// Get tracker.
Tracker t = ((AnalyticsApplication) getApplication()).getTracker();
// Build and send an Event.
t.send(new HitBuilders.EventBuilder()
        .setCategory(categoryId)
        .setAction(actionId)
        .setLabel(labelId)
        .build());

グローバルなTrackerを使い分ける際は以下のようにして管理するようです。 APP_TRACKER アプリ個別の設定
GLOBAL_TRACKER 会社用など共通の設定を使用する場合
ECOMMERCE_TRACKER eコマース用？

public class AnalyticsApplication extends Application {

    private static final String PROPERTY_ID= "your property id";

    public enum TrackerName {
        APP_TRACKER, // Tracker used only in this app.
        GLOBAL_TRACKER, // Tracker used by all the apps from a company. eg: roll-up tracking.
        ECOMMERCE_TRACKER, // Tracker used by all ecommerce transactions from a company.
    }

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

    public AnalyticsApplication() {
        super();
    }

    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);
    }
}
