在Android中实施Google登录时,我无法使用GoogleSignIn(com.google.android.gms.auth.api.signin.GoogleSignIn )和GoogleSignInClient(com.google.android.gms.auth.api.signin.GoogleSignInClient) Studio虽然我可以访问App中的其他类

com.google.android.gms.auth.api.signin.GoogleSignInAccount;
com.google.android.gms.auth.api.signin.GoogleSignInOptions;
com.google.android.gms.common.SignInButton;

我的build.gradle(app)文件的精简版本如下

android {

}

dependencies {

    compile 'com.google.android.gms:play-services-auth:11.4.2'
    compile('com.google.api-client:google-api-client-android:1.23.0') {
        exclude group: 'org.apache.httpcomponents'
    }
    compile('com.google.apis:google-api-services-gmail:v1-rev72-1.23.0') {
        exclude group: 'org.apache.httpcomponents'
    }
    implementation 'com.google.gms:google-services:3.1.2'
}

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

我的build.gradle(包)是

buildscript {

    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0'
        classpath 'com.google.gms:google-services:3.1.2'
    }
}

任何帮助,将不胜感激
