Apparently, if google says You should now have the android-start project open in Android Studio. ,She means it,and not You should now have the android-start project open in Android Studio, without any build-errors . As the instruction says there, you have to get a configuration file from firebase. i.e , create a new project in your firebase acc with name 'friendly chat and in the next page , add its package name and SHA1 KEY. after downloading the json file,add it to your project>app folder, and Rebuild project.

我在尝试运行谷歌的Firebase分析示例应用程序时收到了这个错误:

先决条件:

下载https://github.com/firebase/quickstart-android 添加快速入门/分析到Android Studio

添加程序:

Go to https://firebase.google.com/ Click on "GO TO CONSOLE" Click on "Add Project" Project name: Enter: sample-app Click "Create Project" [Takes about 10 seconds or so...] Click "Continue" On the "Getting Started" page, click "Add Firebase to your Android app" Enter package name for the android app [The full package name appears at the top of the manifest: "com.google.firebase.quickstart.analytics"] Click on download google-services.json In file explorer, add google-services.json to the directory: "quickstart/analytics/app" [Warning: Do not rename the file, it must be: google-services.json] Run 'app' The sample app already contains the necessary Gradle file settings. When adding a new project do: Tools -> Firebase -> Analytics -> Add Event -> Connect App to Firebase. Adding a project via Android Studio ensures that all the Gradle Dependecies are setup.

删除程序:

访问https://firebase.google.com/ 点击“转到控制台” 设置—>项目设置—>删除此应用 设置—>业务群组设置—>删除业务群组 输入项目ID，按delete键

我多次添加和删除示例应用程序，没有任何明显的副作用。

也面临过同样的问题…

在我的情况下，我已经拯救了

google-services.json

as

google_services.json

我尝试了上面提到的每一种解决方案，但都没有帮助…… 错误是你需要把“_”换成“-”(破折号)。

只是将文件重构到google-services。来自google_services的Json。Json工作很有魅力..

希望这能有所帮助!!

附注:我知道这听起来很傻，但这只对我有用……

如果你不再需要它了……

…\ build.gradle:

类路径的com.google.gms:谷歌服务:3.2.0

->

// classpath 'com.google.gms:google-services:3.2.0'

…\ app \ build.gradle:

应用插件:'com.google.gms.google-services'

->

// apply plugin: 'com.google.gms.google-services'

在android studio中:

切换到项目视图，这样你就可以看到实际的项目文件夹结构。 发现谷歌服务。json文件，并将其拖到app目录(由于某种原因，当我使用文件资源管理器添加它时，它把它放在gradle文件夹中)。 清洁/重建项目。

从那以后我就很顺利了。
