How to track android fragments using firebase analytics

Question

In my android application, I have an Activity that has 3 or 4 fragments that can be attached in sequence based on some user or server events.

I would like to track all these fragments as screens in firebase.

So ideally, if possible, is there an API i can invoke in the onCreate of the fragments, and tell firebase that user is currently in fragment1, fragment2 or fragment3?

UPDATE

Since the setCurrentScreen is deprecated, you can use logEvent method

Bundle bundle = new Bundle();
bundle.putString(FirebaseAnalytics.Param.SCREEN_NAME, fragment.getClass().getSimpleName());
bundle.putString(FirebaseAnalytics.Param.SCREEN_CLASS, fragment.getClass().getSimpleName());
mFirebaseAnalytics.logEvent(FirebaseAnalytics.Event.SCREEN_VIEW, bundle);

I've used the following adb commands to check if all is working fine.

adb shell setprop log.tag.FA VERBOSE
adb shell setprop log.tag.FA-SVC VERBOSE
adb logcat -v time -s FA FA-SVC

Once you do that you'll see screen_view events in the logcat. Like this one:

10-15 13:14:13.744 V/FA-SVC (20323): Logging event: origin=app,name=screen_view(_vs),params=Bundle[{ga_event_origin(_o)=app, engagement_time_msec(_et)=31600, ga_previous_class(_pc)=ContentsFragment, ga_previous_id(_pi)=8077407744361472421, ga_previous_screen(_pn)=ContentsFragment, ga_screen_class(_sc)=TestFragment, ga_screen_id(_si)=8077407744361472423, ga_screen(_sn)=TestFragment}]

Previous answer

There is a special method to set a current screen - setCurrentScreen

I used it as follows

mFirebaseAnalytics.setCurrentScreen(this, fragment.getClass().getSimpleName(), fragment.getClass().getSimpleName());

Once the method is called, the following message appears in the LogCat

Logging event (FE): screen_view(_vs), Bundle[{firebase_event_origin(_o)=auto, firebase_previous_class(_pc)=HomeFragment, firebase_previous_id(_pi)=4121566113087629222, firebase_previous_screen(_pn)=HomeFragment, firebase_screen_class(_sc)=StatisticsFragment, firebase_screen_id(_si)=4121566113087629223, firebase_screen(_sn)=StatisticsFragment}]

The following event appears on auto activity tracking:

Logging event (FE): screen_view(_vs), Bundle[{firebase_event_origin(_o)=auto, firebase_previous_class(_pc)=StatisticsFragment, firebase_previous_id(_pi)=4121566113087629223, firebase_previous_screen(_pn)=StatisticsFragment, firebase_screen_class(_sc)=LoginActivity, firebase_screen_id(_si)=4121566113087629224}]

As you see, they are almost the same, so setCurrentScreen is working.

I'm able to see those classes in Firebase Console only on the next day. It is normal for Firebase - it takes time to process such amounts of data.
