Screen tracking support - Firebase 9.8

问题

According Firebase Android SDK Release Notes with 9.8 update we have screen tracking support with android screens and activities... The documentation says that this event works like that:

mFirebaseAnalytics.setCurrentScreen(activity,class_name,class_override_name);

In my case, I don't need overrides class name and I send null value... But i'm waiting 48h and my firebase analytics console doesn't show info about this event, any ideas?

Thanks in advance!

Another very important thing that I've noticed only after two days of intensive struggling: the setCurrentScreen method MUST be called on the UI thread.

I was only able to see that after looking for a light in the Firebase decompiled code:

@MainThread
@Keep
public final void setCurrentScreen(@NonNull Activity var1, @Size(min = 1L,max = 36L) @Nullable String var2, @Size(min = 1L,max = 36L) @Nullable String var3) {
    //...
}

Whenever this method is called a event of type screen_view is logged.

And keep in mind the Firebase size restrictions. The maximum size of a screen name is 36 characters long.

First I had the same question: where is my event with current screen name on the Firebase dashboard? I've called method mFirebaseAnalytics.setCurrentScreen(this, "MainActivity", null); with no result.

Thanks to the comment by Benoit I realized that this method indicates the value of implicit parameter that is automatically attached to any event you send. That means it's not independent event, it's a parameter that will stick to all your events since you set it.

This will be useful if you have changing screens within single Activity. For example when you have multiple fragments with one hosting Activity. And you call this method in each fragment in onResume().

If you want to have distinct metric with the name of your screen - fire explicitly a new event for that.

Bundle params = new Bundle(); 
params.putString(FirebaseAnalytics.Param.ITEM_CATEGORY, "screen");
params.putString(FirebaseAnalytics.Param.ITEM_NAME, "MainActivity");
mFirebaseAnalytics.logEvent(FirebaseAnalytics.Event.VIEW_ITEM, params);

Sets the current screen name, which specifies the current visual context in your app. This helps identify the areas in your app where users spend their time and how they interact with your app.

Note that screen reporting is enabled automatically and records the class name of the current Activity for you without requiring you to call this function. The class name can optionally be overridden by calling this function in the onResume callback of your Activity and specifying the screenClassOverride parameter.

If your app does not use a distinct Activity for each screen, you should call this function and specify a distinct screenName each time a new screen is presented to the user.

The name and classOverride remain in effect until the current Activity changes or a new call to setCurrentScreen is made. I will try to add this method to onResume Method. I do not know the result but i will share my experience.

firebaseAnalytics.setCurrentScreen(activity,screeenName,activity.getClass().getSimpleName());
            firebaseAnalytics.setMinimumSessionDuration(100L);
            params = new Bundle();
            params.putString(FirebaseAnalytics.Param.ITEM_CATEGORY, "screen");
            params.putString(FirebaseAnalytics.Param.ITEM_NAME, screeenName);
            firebaseAnalytics.logEvent(FirebaseAnalytics.Event.VIEW_ITEM, params);

Try using setCurrentScreen as well as manual event fire as firebase doesn't send data immediately to the console...but if event is fired up..all the remaining data is sent to firebase..

Just call that method in onResume(), and check the tracking through DebugView. it worked for me.

Check out the documentation.
