终于得到了

需要更新： Google Play Services (rev 30) and Google Repository (rev 26)

build.gradle(应用程序):

 dependencies { compile "com.google.firebase:firebase-auth:9.0.2"}

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

build.gradle(项目):

dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0'
        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
    }
