所以如果你想通过编程复制google的服务。Json文件从你的所有变体到你的根文件夹。当你切换到特定的变体时，这里有一个解决方案

android {
  applicationVariants.all { variant ->
    copy {
        println "Switches to $variant google-services.json"
        from "src/$variant"
        include "google-services.json"
        into "."
    }
  }
}

这种方法有一个警告，那就是你需要有谷歌服务。Json文件在你的每个变体文件夹这里是一个例子。

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
}

放置你的“谷歌服务”。Json”文件分别在app/src/flavors下 然后是构建。Gradle的应用程序，在android下添加以下代码

gradle.taskGraph.beforeTask { Task task ->
        if (task.name ==~ /process.*GoogleServices/) {
            android.applicationVariants.all { variant ->
                if (task.name ==~ /(?i)process${variant.name}GoogleServices/) {
                    copy {
                        from "/src/${variant.flavorName}"
                        into '.'
                        include 'google-services.json'
                    }
                }
            }
        }
    }

根据@ZakTaccardi的回答，并且假设您不想在两个版本中都使用一个项目，请将此添加到构建的末尾。gradle文件:

def appModuleRootFolder = '.'
def srcDir = 'src'
def googleServicesJson = 'google-services.json'

task switchToStaging(type: Copy) {
    outputs.upToDateWhen { false }
    def flavor = 'staging'
    description = "Switches to $flavor $googleServicesJson"
    delete "$appModuleRootFolder/$googleServicesJson"
    from "${srcDir}/$flavor/"
    include "$googleServicesJson"
    into "$appModuleRootFolder"
}

task switchToProduction(type: Copy) {
    outputs.upToDateWhen { false }
    def flavor = 'production'
    description = "Switches to $flavor $googleServicesJson"
    from "${srcDir}/$flavor/"
    include "$googleServicesJson"
    into "$appModuleRootFolder"
}

afterEvaluate {
    processStagingDebugGoogleServices.dependsOn switchToStaging
    processStagingReleaseGoogleServices.dependsOn switchToStaging
    processProductionDebugGoogleServices.dependsOn switchToProduction
    processProductionReleaseGoogleServices.dependsOn switchToProduction
}

你需要src/staging/google-services文件。Json和src/production/google-services.json。替换您所使用的风味名称。

只需在同一个项目中添加调味应用程序id和口味的名称，下载google-service。Json文件，它将在客户端数组[]中包含所有口味，这将适用于所有口味。
