我使用的是最新的FCM版本：
com.google.firebase:firebase-messaging:9.6.1
也是最新的gradle：
com.android.tools.build:gradle:2.2.1
我添加了classpath 'com.google.gms:google-services:3.0.0'
并添加了插件apply plugin: 'com.google.gms.google-services'
答案 0 :(得分：1)
确保在 依赖项<。>之外声明apply plugin: 'com.google.gms.google-services'。

您还应该将 com.google.firebase：firebase-core：9.6.1 添加到您的依赖项
