How to send screen view event, in order to help Firebase prediction make more accurate prediction

[Yan Cheng Cheok]

I have a single `Activity`, with multiple `Fragment`s in a `ViewPager`.

Currently, this is my way, to send screen view event to both Google Analytics and Firebase


----------


    public static void trackView(Activity activity, String view) {
        trackFBView(activity, view);
        trackGAView(view);
    }
   
    private static void trackFBView(Activity activity, String view) {
        if (activity == null) {
            return;
        }

        FirebaseAnalytics firebaseAnalytics = getFirebaseAnalytics();
        if (firebaseAnalytics == null) {
            return;
        }

        firebaseAnalytics.setCurrentScreen(activity, view, null);
    }

    private static void trackGAView(String view) {
        Tracker tracker = Utils.getTracker();
        if (tracker == null) {
            return;
        }
        tracker.setScreenName(view);
        tracker.send(new HitBuilders.ScreenViewBuilder().build());
    }

    public static FirebaseAnalytics getFirebaseAnalytics() {
        if (false == isGooglePlayServicesAvailable()) {
            return null;
        }

        return FirebaseAnalytics.getInstance(JStockApplication.instance());
    }

In my `ViewPager`'s listener, this is how I send the screen view event.

    private ViewPager.OnPageChangeListener getOnPageChangeListener() {
        return new ViewPager.OnPageChangeListener() {

            @Override
            public void onPageSelected(int position) {

                if (position == 0) {
                    Utils.trackView(DetailedStockFragmentActivity.this, "InfoFragment");

After some testing, I realize I do receive screen view event in GA, **but not in Firebase.**

Later, I realize `firebaseAnalytics.setCurrentScreen` doesn't actually send a screen view event to Firebase. `firebaseAnalytics.setCurrentScreen` merely prepare an implicit parameter. It will only sent across to firebase, during the next event.

Currently, in my fragments, I didn't fire any events explicitly.

I was wondering, in order to help Firebase make better prediction (Help Firebase to identify user in looking at which screen), I was wondering, should I send "Screen View" event explicitly as follow?

    private static void trackFBView(Activity activity, String view) {
        if (activity == null) {
            return;
        }

        FirebaseAnalytics firebaseAnalytics = getFirebaseAnalytics();
        if (firebaseAnalytics == null) {
            return;
        }

        firebaseAnalytics.setCurrentScreen(activity, view, null);

        // Question: Should I do this to help Firebase makes better prediction?
        firebaseAnalytics.logEvent(view + "_ScreenView", null);
    }
