Upgrade to Google Play Services:9.0.0 Error Failed to resolve: com.google.android.gms:play-services-measurement:9.0.0

Question

This was found to fix the problem.

Update your classpath in project level gradle com.google.gms:google-services:2.1.0 to classpath com.google.gms:google-services:3.0.0

Required: Latest versions of Android Studio and Google Play Services

You can add the plugin to your project by updating your top-level build.gradle and your app-level build.gradle files as follows:

classpath 'com.google.gms:google-services:3.0.0'

Like

 // Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        mavenLocal()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.0'
        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
    }
}

allprojects {
    repositories {
        jcenter()
        mavenLocal()
    }
}

Now, you need to add a dependency for Google Play Services. Inside your app's build.gradle add:

compile 'com.google.android.gms:play-services:9.6.1'

Finally

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.2"

    defaultConfig {
        applicationId "// set Yours"
        minSdkVersion 15
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"


    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    packagingOptions {
        exclude 'LICENSE.txt'
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
  compile 'com.google.android.gms:play-services-gcm:9.6.1'
    compile 'com.android.support:appcompat-v7:24.2.0'

}

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

GCM has been rebranded to Firebase Cloud Messaging (FCM), If you want to use com.google.android.gms:play-services:9.0.0 read this article FCM. Do this maybe work, modify your build.gradle file to use the plugin.

buildscript {
  dependencies {
    // Add this line
    classpath 'com.google.gms:google-services:3.0.0'
  }
}

The easiest way I found is to use the latest version for all.

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
//apply plugin: 'com.google.gms.google-services' //Firebase
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:design:25.3.1'
compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha8'
compile 'com.google.firebase:firebase-auth:10.2.6'
compile 'com.google.android.gms:play-services-auth:10.2.6' //10.2.6
compile 'com.google.firebase:firebase-core:10.2.6' // used for FCM
compile 'com.google.firebase:firebase-messaging:10.2.6' // used for FCM
testCompile 'junit:junit:4.12'
//  apply plugin: 'com.google.gms.google-services'

}

EXPLAINATION

apply plugin: 'com.google.gms.google-services' // Add this at bottom.

• First, apply plugin: 'com.google.gms.google-services' // Add this at bottom.

• Then, add these into dependencies

  compile 'com.google.firebase:firebase-auth:10.2.6' // make suere this is in latest version.

  compile 'com.google.android.gms:play-services-auth:10.2.6' //10.2.6 Latest

  compile 'com.google.firebase:firebase-core:10.2.6' // used for FCM

  compile 'com.google.firebase:firebase-messaging:10.2.6' // used for FCM

Suppose if you have firebase-auth 10.2.6 that is latest today 25, May 2017, But simultaneously you're using play-services-auth:9.0.0 or below than latest, then they both can't make the connection and show you the error.

I hope this helped.
