Someone knows if it can be possible on android or if I have to use Analytics, event and hit builders?
It is for tracking popular activities and fragments.
Sorry if it's a dumb question but i'm newbie and I don't know what summary and guide I have to follow for this.
Yes, you can. You can do something like
Bundle params = new Bundle(); params.putString("activityName", getClass.getSimpleName()); mFirebaseAnalytics.logEvent("startActivity", params);
You can read their documentation from here
