Does dynamic_link_first_open event also trigger first_open?

Question

Basicly I wanted to count the following firebase events:

• app_open
• first_open
• dynamic_link_app_open
• dynamic_link_first_open

I thought, that usually only one of this events is triggered when a user opens the app, depending on if he/she comes through a dynamic link or not and if he/she opens the app for the first time or not. But now I detected, that I have some first_open and dynamic_link_first_open events with the same app_instance_id with only 2-10 seconds difference in their timestamp. Does that mean, that if a user open the app for the first time through a dynamic link both dynamic_link_first_open and first_open events are triggered? And what about dynamic_link_app_open and app_open?

Thanks a lot!

Answer 1

You're correct. If the user opens the app for the first time using dynamic link, it will log both first_open event and the dynamic_link_first_open event.

The dynamic_link_app_open event will be logged when the user re-opens the app via a Firebase Dynamic Link.

On the other hand, the app_open is one of the Google Analytics for Firebase (GA4F) suggested events and can be used (or logged) when an app is moved to foreground state. This will help you to understand how often users leave and return during the course of a session. Although Sessions are automatically reported, this event can provide further clarification around the continuous engagement of app-users.
