Firebase analytics find custom event parameters

Question

I create some custom parameter in my android app as the Firebase doc

//frist way
firebaseAnalytics.logEvent(FirebaseAnalytics.Event.SELECT_ITEM) {
    param(FirebaseAnalytics.Param.ITEM_ID, "3")
    param(FirebaseAnalytics.Param.ITEM_NAME, "requestCargo")
    param(FirebaseAnalytics.Param.CONTENT_TYPE, "text")
}

//second way
firebaseAnalytics.logEvent("create_cargo") {
    param("user_id", "1")
    param("action_type", "videoCall")
}

1. I can see the event in Firebase -> Analytics -> Event
2. There is no enable custom events
3. there is no custom reporting tab

I could not see my params user_id, action_type

But I can see that in Firebase -> Analytics -> Realtime

Please help me if you know how to show params

Answer 1

I found the change.

There is a Custom definitions in the Analytics menu

You should create your custom definitions on this page

And set the Event parameter as your param in your app

you should wait some hours or a day. after that you can see the result on the Event page in your event
