在android studio中无法解析用于Google集成的符号'Auth' [英] Cannot resolve symbol 'Auth' for google integration in android studio

问题描述

我是androidstudio的新手。我在eclipse中完成了谷歌的整合，但在工作室遇到问题。
i正在按照本网站的步骤进行操作： https：//开发者.google.com /身份/登录/安卓/登录？配置=真正的

但我有问题。

 <$ c无法解析符号'Auth'，这是我需要的API，也无法解析'SignInButton'，请参阅代码： $ c> import android.os.Bundle; 
导入android.support.v7.app.AppCompatActivity; 
 import com.google.android.gms.auth.api.Auth; 
导入com.google.android.gms.auth.api.signin.GoogleSignInOptions; 
 import com.google.android.gms.common.ConnectionResult; 
 import com.google.android.gms.common.SignInButton; 
 import com.google.android.gms.common.api.GoogleApiClient; 
 
 
公共类MainActivity扩展AppCompatActivity实现GoogleApiClient.OnConnectionFailedListener {
 GoogleSignInOptions gso; 
 GoogleApiClient mGoogleApiClient; 
 @Override 
 protected void onCreate（Bundle savedInstanceState）{
 super.onCreate（savedInstanceState）; 
 setContentView（R.layout.activity_main）; 
 gso = new GoogleSignInOptions.Builder（GoogleSignInOptions.DEFAULT_SIGN_IN）.requestEmail（）。build（）; 
 mGoogleApiClient = new GoogleApiClient.Builder（this）
 .enableAutoManage（this / * FragmentActivity * /，this / * OnConnectionFailedListener * /）
 .addApi（Auth.GOOGLE_SIGN_IN_API，gso）
 .build（）; 
} 
 
 @Override 
 public void onConnectionFailed（ConnectionResult connectionResult）{
 
 
 
 $ / $ c $ 
 
 
 
  
  //顶级构建文件，您可以在其中添加所有子项目/模块共有的配置选项。 
 $ b buildscript {
 repositories {
 jcenter（）
} 
依赖关系{
 classpath'com.android.tools.build:gradle： 1.3.0'
 classpath'com.google.gms：google-services：1.5.0-beta2'
 
 //注意：不要在这里放置您的应用程序依赖关系;它们属于单个模块build.gradle文件中的
 // 
} 
} 
 
 allprojects {
存储库{
 jcenter（）
 
 
 
任务清理（类型：删除）{
删除rootProject.buildDir 
} 
  
这是我的app gradle： 
 
 
  apply plugin： 'com.android.application'
 
 android {
 compileSdkVersion 23 
 buildToolsVersion23.0.2
 
 defaultConfig {
 applicationIdcom .creaa.admin.googlesignin
 minSdkVersion 11 
 targetSdkVersion 23 
 versionCode 1 
 versionName1.0
} 
 buildTypes {
 release { 
 minifyEnabled false 
 proguardFiles getDefaultProguardFile（'proguard-android.txt'），'proguard-rules.pro'
} 
} 
 compileOptions {
 sourceCompatibility JavaVersion.VERSION_1_7 
 targetCompatibility JavaVersion.VERSION_1_7 
 
 
 
依赖关系{
编译fileTree（包括：''.jar']，dir：'libs'）
 testCompile'junit：junit：4.12'
 compile'c​​om.android.support:appcompat-v7:23.1.0'
 apply plugin：'com.google.gms.google-services'
 
 
  
请帮助我。
解决方案
 
 
 
 
放置 apply plugin：'com.google.gms.google-services'  apply apply plugin：'com.android.application'。
 
 
 
 
添加编译'com.google.android.gms：play-services-auth：8.3.0'在依赖关系块中。这将为您的项目添加相关的依赖项。
 
 
 
i am new in androidstudio. i have done integration of google in eclipse but am having issues in studio.
i am following step by step from this site : https://developers.google.com/identity/sign-in/android/sign-in?configured=true

but i am having an issue. i am getting an error that Cannot resolve symbol 'Auth' which i need for API and also cannot resolve 'SignInButton', see the code:
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import com.google.android.gms.auth.api.Auth;
import com.google.android.gms.auth.api.signin.GoogleSignInOptions;
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.SignInButton;
import com.google.android.gms.common.api.GoogleApiClient;


public class MainActivity extends AppCompatActivity implements GoogleApiClient.OnConnectionFailedListener {
GoogleSignInOptions gso;
    GoogleApiClient mGoogleApiClient;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN).requestEmail().build();
       mGoogleApiClient = new GoogleApiClient.Builder(this)
    .enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
    .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
    .build();
    }

    @Override
    public void onConnectionFailed(ConnectionResult connectionResult) {

    }
}
this is my project gradle:
// 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:1.3.0'
        classpath 'com.google.gms:google-services:1.5.0-beta2'

        // 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
}
this is my app gradle:
apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.creaa.admin.googlesignin"
        minSdkVersion 11
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.0'
    apply plugin: 'com.google.gms.google-services'

}
Please help me.
解决方案

Put apply plugin: 'com.google.gms.google-services' beneath apply plugin: 'com.android.application'.
Add compile 'com.google.android.gms:play-services-auth:8.3.0' inside dependencies block. This will add related dependencies to your project.
