How to send custom parameter along with reserve event to firebase analytics

问题

I am able to send custom parameter along with custom event to firebase analytics in android using below method :-

 Bundle bundle = new Bundle();
                bundle.putString("Action", "Action Perform Android");
                bundle.putString("Category", "CustomEvent Android");
                bundle.putString("Label", "click me");
                firebaseAnalytics.logEvent("Button_clicked", bundle);

Above method is working and we can see this event on firebase console.

Here are some event that event name is reserve and we can not use this name again to send event to Firebase analytics like notification_dismiss, notification_open etc. These predefined events are automatically collected by Firebase.

Now I want to send some custom parameter along with these above event. For example when notification_open event fired, I want to add notification title as a custom parameter along with this event. How can we override notification_open event or how can we set notification title custom parameter along with this event in android?

回答1:

There is no way to add custom parameters to events that are automatically sent. You will have to define your own event to add those parameters to.

Once you've done that, you can combine the standard and custom event in BigQuery, to get both the default and the custom parameters in a single report.
