问题

This question already has an answer here:

Do I need Firebase Core for Firebase Database? (1 answer)

Closed last year.

While compiling I'm getting a warning like this,

The app Gradle file must have a dependency on com.google.firebase:firebase-core for Firebase services to work as intended.

just add the below line

updated

implementation 'com.google.firebase:firebase-core:17.0.0'

I think your gradle has the below implementation missing. Add this to your app level build.gradle.

com.google.firebase:firebase-core:16.0.4
