Track Screenviews

Google Analytics tracks screen transitions and attaches information about the current screen to events, enabling you to track metrics such as user engagement or user behavior per screen. Much of this data collection happens automatically, but you can also manually log screenviews. Manually tracking screens is useful if your app does not use a separate UIViewController or Activity for each screen you may wish to track, such as in a game.

Automatically track screens

Analytics automatically tracks some information about screens in your application, such as the class name of the UIViewController or Activity that is currently in focus. When a screen transition occurs, Analytics logs a screen_view event that identifies the new screen. Events that occur on these screens are automatically tagged with the parameter firebase_screen_class (for example, menuViewController or MenuActivity) and a generated firebase_screen_id. If your app uses a distinct UIViewController or Activity for each screen, Analytics can automatically track every screen transition and generate a report of user engagement broken down by screen. If your app doesn't, you can still get these reports by manually logging screen_view events.

Manually track screens

You can manually log screen_view events whether or not automatic tracking is enabled. You can log these events in the viewDidAppear state for iOS and onResume for Android. When screen_class is not set, Analytics sets a default value based on the UIViewController or Activity that is in focus when the call is made.
