ionic原生fcm插件问题

Question

我想在我的ionic 3应用程序中实现firebase推送通知。我已经添加了ionic natice fcm插件。但是当我使用以下命令构建应用程序时

ionic cordova build android

但它给了我一个错误，如下所示：

在我添加FCM插件之前，一切都很正常。我的项目信息如下：

global packages:

    @ionic/cli-utils : 1.4.0
    Cordova CLI      : 6.5.0
    Ionic CLI        : 3.4.0

local packages:

    @ionic/app-scripts              : 1.3.12
    @ionic/cli-plugin-cordova       : 1.4.0
    @ionic/cli-plugin-ionic-angular : 1.3.1
    Cordova Platforms               : android 6.1.2
    Ionic Framework                 : ionic-angular 3.5.0

System:

    Node       : v7.8.0
    OS         : Windows 10
    Xcode      : not installed
    ios-deploy : not installed
    ios-sim    : not installed
    npm        : 4.2.0

此外，我尝试删除所有插件和平台，并读取它。但是没有解决方案！:(

此处提供的解决方案：https://forum.ionicframework.com/t/ionic-native-fcm-plugin-issue/96601/6

最终，我找到了解决方案，下面是我所做的:将android.gms:play-services-ads替换为firebase:firebase-ads：

build.gradle project.properties plugin.xml还会检查是否在android.gms:play-services-ads:X.X.X之后提供了任何版本，然后将其替换为android.gms

在将Ionic原生FCM插件添加到您的应用程序之前，您需要在google firebase控制台上配置您的应用程序，并添加到应用程序根文件夹中的GoogleService-info.plist & google-services.json。

尝试删除插件，添加文件，然后重新添加插件。
