我将我的项目更新到最新的Play服务类路径“com.google.gms:google-services:1.5.0-beta2”。我也在我的app.gradle文件中使用最新版本的playservices:
compile 'com.google.android.gms:play-services-location:8.3.0'
compile 'com.google.android.gms:play-services-gcm:8.3.0'
然而，当我编译时，Gradle抛出异常如下
Error:Execution failed for task ':app:processDebugGoogleServices'. > File google-services.json is missing from module root folder. The Google Services Plugin cannot function without it.

从开发人员的站点转到配置文件，并将其粘贴到当前项目的应用程序级目录中。
其他回答
非常简单的 点击工具->Firebase->连接到Firebase，然后点击同步 这肯定会奏效。
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。
https://developers.google.com/mobile/add
选择开始，进入设置logo，然后是项目设置 之后，你会看到下面的平台，如web,android,ios。根据您的喜好选择。 然后下载 google服务。json文件
复制该文件并粘贴到
YourProjec / app目录 最后再次同步。
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。
对于从firebase codelabs教程第3步来到这里的人:请转到第4页。
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.
