After integrating Google login and Google map, run the project, report

Error:Execution failed for task ':app:processDebugGoogleServices'.
> 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 9.0.0.

Look at the project. The build

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'
        classpath 'com.novoda:bintray-release:0.3.4'
        classpath 'com.google.gms:google-services:3.0.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

Moreover is app. The build

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

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
     //google map
    compile 'com.google.android.gms:play-services-maps:9.8.0'
    compile 'com.google.android.gms:play-services-location:9.8.0'
    //google login
    compile 'com.google.android.gms:play-services-auth:9.8.0'
    }

According to the latest version of the document, if 9.8.0 is changed to 9.0.0, then the map’s mmapView.onstop (), mmapView.onstart (); The method is not integrated, nor is it possible to change Google-Services :3.0.0 to document query 3.1.1.
The final solution will be

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

Instead of

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

Can be
