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。

我正在使用谷歌服务。json文件，从这里创建:https://developers.google.com/mobile/add?platform=android&cntapi=gcm&cnturl=https:%2F%2Fdevelopers.google.com%2Fcloud-messaging%2Fandroid%2Fclient&cntlbl=Continue%20Adding%20GCM%20Support&%3Fconfigured%3Dtrue

在json结构中，有一个称为客户机的json数组。如果你有多种口味，只需在这里添加不同的属性。

    "project_id": "PRODJECT-ID",
    "project_number": "PROJECT-NUMBER",

        "client_type": 1,

    },
    {

        "client_id": "android:PACKAGE-NAME-2",
        "client_type": 1,
        "android_client_info": {
          "package_name": "PACKAGE-NAME-2"
        }
      },
      "oauth_client": [],
      "api_key": [],
      "services": {
        "analytics_service": {

        "cloud_messaging_service": {

          "apns_config": []
        },
        "appinvite_service": {
          "status": 1,
          "other_platform_oauth_client": []
        },
        "google_signin_service": {
          "status": 1
        },
        "ads_service": {
          "status": 1
        }
      }
    }
  ],
  "client_info": [],
  "ARTIFACT_VERSION": "1"
}

在我的项目中，我使用相同的项目id，当我在上面的url中添加第二个package-name时，谷歌为我提供了一个包含json-data中的多个客户端的文件。

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。

我目前在同一个应用程序包中使用两个GCM项目Id。我加入了谷歌服务。我的第一个GCM项目的json，但我从第一个切换到第二个只改变SENDER_ID:

    String token = instanceID.getToken(SENDER_ID,GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);

(在这一点上，我认为谷歌的服务。Json不是强制性的)

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
}

写了一篇关于这个问题的文章。

有一个类似的问题(使用BuildTypes而不是flavour)，并像这样修复了它。

利用Gradle的依赖管理系统。我创建了两个任务switchToDebug和switchToRelease。要求在运行assemblerrelease时，也运行switchToRelease。调试也是一样。

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

task switchToDebug(type: Copy) {
    def buildType = 'debug'
    description = 'Switches to DEBUG google-services.json'
    from "${srcDir}/${buildType}"
    include "$googleServicesJson"
    into "$appModuleRootFolder"
}

task switchToRelease(type: Copy) {
    def buildType = 'release'
    description = 'Switches to RELEASE google-services.json'
    from "${srcDir}/${buildType}/"
    include "$googleServicesJson"
    into "$appModuleRootFolder"
}

afterEvaluate {
    processDebugGoogleServices.dependsOn switchToDebug
    processReleaseGoogleServices.dependsOn switchToRelease
}

编辑:使用processDebugFlavorGoogleServices/processReleaseFlavorGoogleServices任务在每个flavor级别上修改它。
