This fixed it for me after hours of plundering my code.

I am using firebase, FCM, and google-services and they were all doing this:
apply plugin: 'com.google.gms.google-services'

So I removed it from:

portal-build.gradle in 2 places
in:
platforms->android->cordova-plugin-firebase
platforms->android->cordova-support-google-services

^ to make sure google services was only applied once.

Also I made sure every *.gradle file in platform->android pointed to the same com.google.gms:google-services version. In my case 4.0.2 works.

Then as a unexpected bonus I had to change the project.properties file in platform->android

There I made sure
com.android.support:support-v4:27.1.0 was called, and I removed every other reference to com.android.support:support-v4 from it.

This works for me:
