Your Google Play Services version and Firebase Version don’t match.

It should look like this:

implementation 'com.google.android.gms:play-services:11.4.2'
implementation 'com.google.firebase:firebase-core:11.4.2'

Be aware that you shouldn’t include the whole bundled Play Services as it increases your APK and Dex size drastically. Include only the components you need.
