java – 谷歌登录签名apk无法正常工作

1.我生成了带有keyhash和包名称的google-services.json文件
2.包括所有类级别和应用程序级别的依赖关系

// 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:2.0.0-alpha6'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}
}
 allprojects {
  repositories {
     jcenter()
   }
  }

应用程序gradle文件

apply plugin: 'com.android.application'
