Error:Execution failed for task ':app:processDebugGoogleServices'. when add firebase-messaging

Question

When I add the line: compile 'com.google.firebase:firebase-messaging:10.0.1' in the file build.gradle and click in sync now in the AndroidStudio:

Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 10.0.1.

I removed the line apply plugin: 'com.google.gms.google-services' then the error disappear. But the firebase-auth failure: Caused by: java.lang.IllegalStateException: Default FirebaseApp is not initialized in this process br.ufrn.imd.sgr. Make sure to call FirebaseApp.initializeApp(Context) first.

Help me, please.

build.gradle(Project)

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

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

Here the deal: you added too old dependency. Your Firebase Auth dependency version is 11.0.2:

compile 'com.google.firebase:firebase-auth:11.0.2'

And you added one more Firebase dependency with version 10.0.1:

compile 'com.google.firebase:firebase-messaging:10.0.1'

So there is dependencies version conflict. That's why you have Gradle build error when you are trying to sync.

To solve this just make your firebase-messaging dependency version to latest one and reapply Google Services Gradle plugin:

dependencies {
    ...

    compile 'com.google.firebase:firebase-auth:11.0.2'
    compile 'com.google.firebase:firebase-messaging:11.0.2'

    ...
}

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

Hope this helps.
