Answer 1

If you recently update your Android Studio to 3.3.1 that have a problem with com.google.gms:google-services (Below 4.2.0) dependencies So please update com.google.gms:google-services to 4.2.0

dependencies {
classpath 'com.android.tools.build:gradle:3.3.1'
classpath 'com.google.gms:google-services:4.2.0'
}

Answer 2

may be you forgot add

apply plugin: 'com.google.gms.google-services'

to the bottom of build.gradle.
