If you want to use messaging, you have to add the messaging module. Right now you only added the core module.
如果要使用消息传递，则必须添加消息传递模块。现在您只添加了核心模块。
So go ahead and include
所以继续并包括
compile 'com.google.firebase:firebase-messaging:9.4.0'
All the available modules can be found at the bottom of https://firebase.google.com/docs/android/setup
所有可用的模块都可以在https://firebase.google.com/docs/android/setup的底部找到
