android - Do I need Firebase Core for Firebase Database?

Question

I use only Firebase Database and I've added only the next dependency:

implementation 'com.google.firebase:firebase-database:16.0.1'

it seems works ok

but during compilation I get next warning

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

Should I still add Core? like:

implementation 'com.google.firebase:firebase-core:16.0.1'
implementation 'com.google.firebase:firebase-database:16.0.1'
