Can't get event from Android.

Hi, I use Google Analytics for firebase and I try to sent `logEvent( )` to firebase from Android app but I can't see any event show (it's show only `first_open, user_engagement, screen_view` when I open it at first time),

I try to use `logEvent( )` in iOS too and it's work fine.

I already add
`classpath 'com.google.gms:google-services:3.1.1'` in android/build.gradle
`apply plugin: 'com.google.gms.google-services'` at bottom of android/app/build.gradle file

Thanks.
