here is my build.gradl

Answer 1

I too had the same problem when i was a newbie to Android Development. Though you had everything in place like below

compile 'com.google.android.gms:play-services:10.0.1'
compile 'com.google.firebase:firebase-messaging:10.0.1'

and you might be placed even the below line in your build.gradle(app level)

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

placing the above piece of code at the bottom of your build.gradle file fix your error

More important thing check your build.gradle(project level) file

apply plugin:  dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'
        classpath 'com.google.gms:google-services:3.0.0'
    }'

com.google.gms:google-services:3.0.0 is placed or not .it won't support old verisons
