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”

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);

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

    gradle.taskGraph.afterTask { Task task ->
        if (task.name ==~ /process.*GoogleServices/) {
            android.applicationVariants.all { variant ->
                if (task.name ==~ /(?i)process${variant.flavorName}(Debug|Release)GoogleServices/) {
                    delete fileTree(".").matching {
                        include 'google-services.json'
                    }
                }
            }
        }
    }

我们对调试构建有不同的包名(*.debug)，所以我想要一些基于flavor和buildType的东西，而不必在processDebugFlavorGoogleServices的模式中编写任何与flavor相关的东西。

我在每个版本中创建了一个名为“google-services”的文件夹，包含了json文件的调试版本和发布版本:

在gradle文件的buildTypes部分，添加以下内容:

    applicationVariants.all { variant ->
            def buildTypeName = variant.buildType.name
            def flavorName = variant.productFlavors[0].name;

            def googleServicesJson = 'google-services.json'
            def originalPath = "src/$flavorName/google-services/$buildTypeName/$googleServicesJson"
            def destPath = "."

            copy {
                if (flavorName.equals(getCurrentFlavor()) && buildTypeName.equals(getCurrentBuildType())) {
                    println originalPath
                    from originalPath
                    println destPath
                    into destPath
                }
            }
    }

当你切换构建变量时，它会自动在你的应用模块的根处复制正确的json文件。

在build.gradle的根中添加这两个被调用的方法，以获取当前风格和当前构建类型

def getCurrentFlavor() {
    Gradle gradle = getGradle()
    String  tskReqStr = gradle.getStartParameter().getTaskRequests().toString()

    Pattern pattern;

    if( tskReqStr.contains( "assemble" ) )
        pattern = Pattern.compile("assemble(\\w+)(Release|Debug)")
    else
        pattern = Pattern.compile("generate(\\w+)(Release|Debug)")

    Matcher matcher = pattern.matcher( tskReqStr )

    if( matcher.find() ) {
        println matcher.group(1).toLowerCase()
        return matcher.group(1).toLowerCase()
    }
    else
    {
        println "NO MATCH FOUND"
        return "";
    }
}

def getCurrentBuildType() {
    Gradle gradle = getGradle()
    String  tskReqStr = gradle.getStartParameter().getTaskRequests().toString()

        if (tskReqStr.contains("Release")) {
            println "getCurrentBuildType release"
            return "release"
        }
        else if (tskReqStr.contains("Debug")) {
            println "getCurrentBuildType debug"
            return "debug"
        }

    println "NO MATCH FOUND"
    return "";
}

就是这样，你不必担心从你的gradle文件中删除/添加/修改口味，它得到调试或发布谷歌服务。自动json。

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。

}

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。

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。
