谷歌在play服务插件的2.0版本中包含了对不同口味的支持。由于这个版本的gradle插件com.google.gms:google-services:2.0.0-alpha3

你可以这样做

第一步:添加到gradle

// To auto-generate google map api key of google-services.json
implementation 'com.google.android.gms:play-services-maps:17.0.0'

第二步:在应用程序标签中添加到AndroidManifest.xml

<meta-data
    android:name="com.google.android.geo.API_KEY"
    android:value="@string/google_api_key" />

第三步:从firebase下载每个flavor JSON文件并添加

app/src/
    flavor1/google-services.json
    flavor2/google-services.json

3.0.0版本的插件在这些位置搜索JSON文件(考虑到你有一个flavor flavor1和一个构建类型调试):

/app/src/debug/google-services.json
/app/src/debug/flavor1/google-services.json
/app/google-services.json

即使使用flavorDimensions，我也能做到。一个维度是免费和付费，另一个维度是模拟和刺激。我还有3个构建类型:调试、发布和登台。这是它在我的FreeProd项目中的外观:

有多少谷歌服务?json文件将取决于你的项目的特点，但你将需要至少一个json文件为每个谷歌项目。

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);

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。

根据Firebase文档，你也可以使用字符串资源来代替google-services.json。

因为这个提供者只是读取已知名称的资源，另一种选择是直接将字符串资源添加到应用程序中，而不是使用谷歌Services gradle插件。你可以这样做: 从根build.gradle中移除google-services插件 删除google服务。来自项目的Json 直接添加字符串资源 删除应用插件:'com.google.gms。你的应用build.gradle中的Google-services

示例strings.xml:

<string name="google_client_id">XXXXXXXXX.apps.googleusercontent.com</string>
<string name="default_web_client_id">XXXX-XXXXXX.apps.googleusercontent.com</string>
<string name="gcm_defaultSenderId">XXXXXX</string>
<string name="google_api_key">AIzaXXXXXX</string>
<string name="google_app_id">1:XXXXXX:android:XXXXX</string>
<string name="google_crash_reporting_api_key">AIzaXXXXXXX</string>
<string name="project_id">XXXXXXX</string>

嘿，朋友也寻找名称只使用小写，那么你不会得到这个错误

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.

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