我已经尝试将FCM添加到我的android应用程序中将近48小时了.我一直在Android Studio上因这两个错误而失败.我已经尝试过此中的所有解决方案发布.仍然我无法解决它.

I have been tryong to add FCM to my android application for almost 48 hours now. I am keep on failing with these two errors on Android Studio. I have tried all the solutions in this post. Still I couldn't fix it.

我希望将Firebase云消息传递集成到我的应用程序中.因此，我做了以下工作.

I want firebase cloud messaging to be integrated in my app. So I did the followings.

• 在firebase控制台中创建了一个应用
• 包含.json配置文件
• 添加了SDK
• implementation 'com.google.firebase:firebase-messaging:17.0.0' (在应用级别的gradle中)
• apply plugin: 'com.google.gms.google-services'(在应用程序级别gradle文件中，最后 行)
• classpath 'com.google.gms:google-services:4.0.1' (在项目级别的gradle中)
• 添加了存储库 google()(在项目级别的gradle中)

• Created an app in the firebase console
• Included the .json config file
• Added the SDK
• implementation 'com.google.firebase:firebase-messaging:17.0.0' (In the app level gradle)
• apply plugin: 'com.google.gms.google-services' (In the app level gradle file last line)
• classpath 'com.google.gms:google-services:4.0.1' (In the project level gradle)
• Added the repository google() (In the project level gradle)

我尝试了很多次同步，并且不断收到错误消息

另一方面，我正在使用gradle插件3.1.3

On a side note, I am using the gradle plugin 3.1.3

    classpath 'com.android.tools.build:gradle:3.1.3'

有人可以在这里帮我吗?

Can someone please give me a hand here please.

推荐答案

jcenter()有时充当某些Google依赖项的镜像存储库.在Gradle构建过程中，它将在repositories {...}块中列出的第一个条目中查找依赖项.因此，如果此存储库已损坏或由于任何依赖性而发生不良情况，该过程将失败.

jcenter() sometimes act as a mirror repository for some Google dependencies. During Gradle building process, it looks for dependencies in the first entry listed in your repositories {...} block. So if this repository is broken or something bad occurs with any dependency the process will fail.

这里有一个推荐的存储库列表顺序

Here there is a recommended order for repository list

    repositories {
        google()
        maven {
            url 'https://maven.google.com/'
        }
        jcenter()
    }
