无法解析符号 GOOGLE_SIGN_IN_API.. Google 在我的应用程序中登录,无法访问变量 Auth.GOOGLE_SIGN_IN_API

Cannot resolve symbol GOOGLE_SIGN_IN_API.. Google sign-in in my app, Unable to access variable Auth.GOOGLE_SIGN_IN_API

我一直在将 Google 登录集成到我的 Android 应用程序中。 我一直在关注 Google 的 Android 教程。 (https://developers.google.com/identity/sign-in/android/sign-in) 过程中遇到了这个问题。

// 构建一个 GoogleApiClient,可以访问 Google 登录 API 和 // gso 指定的选项。

mGoogleApiClient = new GoogleApiClient.Builder(this)
    .enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
    .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
    .build();

无法解析符号 GOOGLE_SIGN_IN_API 这就是我面临的问题。

我一直严格遵循上述 link 中描述的所有步骤。所有的依赖项和插件都是一样的,问题仍然存在。我该如何解决这个问题并继续前进?任何答案将不胜感激..

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

这是我的项目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:2.3.2'
        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()
    }
}

更新您的 gradle 文件

    compile 'com.google.android.gms:play-services-auth:10.2.0'
    compile 'com.google.android.gms:play-services:10.2.0'

用这个替换你的 gradle 依赖项,如有任何疑问请告诉我
