受到上面@ahmed_khan_89答案的启发。我们可以直接这样保存在gradle文件中。

android{

// set build flavor here to get the right Google-services configuration(Google Analytics).
    def currentFlavor = "free" //This should match with Build Variant selection. free/paidFull/paidBasic

    println "--> $currentFlavor copy!"
    copy {
        from "src/$currentFlavor/"
        include 'google-services.json'
        into '.'
    }
//other stuff
}

remove the existing google-services.json from your project. Build > Clean Project compile and run your app look at the error message that comes up to figure out where you can put your google-services.json..mine looked like this File google-services.json is missing. The Google Services Plugin cannot function without it.

注意:它还关心flavorDimensions中声明的顺序。我的是flavorDimensions“dev_suffix”，“environment”

根据ahmed_khan_89的回答，您可以将“复制代码”放在产品风味中。

productFlavors {
    staging {
        applicationId = "com.demo.staging"

        println "Using Staging google-service.json"
        copy {
            from 'src/staging/'
            include '*.json'
            into '.'
        }
    }
    production {
        applicationId = "com.demo.production"

        println "Using Production google-service.json"
        copy {
            from 'src/production/'
            include '*.json'
            into '.'
        }
    }
}

这样你就不必手动切换设置了。

谷歌服务。Json文件是不必要的接收通知。只要在你的构建中为每种味道添加一个变量。gradle文件:

buildConfigField "String", "GCM_SENDER_ID", "\"111111111111\""

使用这个变量BuildConfig。GCM_SENDER_ID代替getString(R.string.gcm_defaultSenderId)注册时:

instanceID.getToken(BuildConfig.GCM_SENDER_ID, GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);

嘿，朋友也寻找名称只使用小写，那么你不会得到这个错误

Google -services插件的目的是简化谷歌特性的集成。

因为它只从google服务中生成android资源。json文件，过于复杂的gradle逻辑否定了这一点，我认为。

因此，如果google文档没有说明特定的google特性需要哪些资源，我建议为每个相关的buildtype/flavor生成json文件，看看插件生成了哪些资源，然后手动将这些资源放入各自的src/buildtypeORflavor/res目录中。

删除对google-services插件和json文件的引用，就完成了。
