Kann nicht lösen Symbol "Plus" in Android Google Plus Integrationsprojekt

Question

Versuchen Sie, Google Plus in meiner App zu integrieren, kann aber nicht finden "com.google.android.gms.plus.Plus" -Klasse. Ich aktualisiere den Google Play-Dienst gemäß der neuesten Version.

MainActivity.java:

mGoogleApiClient = new GoogleApiClient.Builder(this) 
      .enableAutoManage(this /* FragmentActivity */, 
        this /* OnConnectionFailedListener */) 
      .addApi(Plus.API) 
      .addScope(Scopes.PLUS_LOGIN) 
      .addScope(Scopes.PLUS_ME) 
      .build(); 

build.gradle (Projektebene):

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

buildscript { 
repositories { 
    jcenter() 
} 
dependencies { 
    classpath 'com.android.tools.build:gradle:2.1.2' 
    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() 
    } 
} 

task clean(type: Delete) { 
    delete rootProject.buildDir 
} 

build.gradle (App-Ebene):

apply plugin: 'com.android.application' 


android { 
compileSdkVersion 23 
buildToolsVersion "23.0.2" 

defaultConfig { 
    applicationId "com.apt.googleintegration" 
    minSdkVersion 21 
    targetSdkVersion 23 
    versionCode 1 
    versionName "1.0" 
} 
buildTypes { 
    release { 
     minifyEnabled false 
     proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
    } 
} 
} 

dependencies { 
    compile fileTree(include: ['*.jar'], dir: 'libs') 
    testCompile 'junit:junit:4.12' 
    compile 'com.android.support:appcompat-v7:23.4.0' 
    compile 'com.android.support:design:23.4.0' 
    compile 'com.google.android.gms:play-services-auth:9.0.2' 
} 
apply plugin: 'com.google.gms.google-services'

Es wird, wenn Sie arbeiten Fügen Sie in Ihrer Gradel-Datei Folgendes hinzu:

compile 'com.google.android.gms:play-services:9.0.2'
