找不到符号“消息”在com.google.firebase.messaging.FirebaseMessagingService中

问题描述

我尝试使用Firebase 9.2.1库访问FirebaseMessagingService。我已经成功创建了一个项目，然后下载JSON文件。我终于将这个JSON文件与我的项目集成在一起。 FirebaseInstanceIDService运行正常，但显示FirebaseMessagingService错误。所以我检查了我的项目文件夹里面的android studio。然后我发现firebase-messaging 9.2.1库缺失。我该如何解决这个问题。我已经升级了所有的SDK库。请帮我解决这个问题。

解释了Firebase云消息传递的设置在中。

I am trying to access FirebaseMessagingService using firebase 9.2.1 library. I have successfully created a project then download the JSON file. I have finally integrated this JSON file with my project. FirebaseInstanceIDService is running fine but showing error with FirebaseMessagingService. So i checked my project folder inside android studio. Then i find that firebase-messaging 9.2.1 library is missing. How can i resolve this issue. I have already upgraded all of the SDK libraries. Please help me to fix this issue.

解决方案

You need to add Firebase Messaging to your dependencies:

compile 'com.google.firebase:firebase-messaging:9.2.1'

Setup for Firebase Cloud Messaging is explained in the documentation.
