Question

我想在我的离子3应用程序中实现firebase推送通知。我添加了离子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

但它给我一个错误如下：

在添加FCM插件之前，一切正常。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，我试图删除所有插件和平台并读取它。但没有解决方案！：（

此处找到解决方案：https://forum.ionicframework.com/t/ionic-native-fcm-plugin-issue/96601/6

最后，我找到了解决方案，这就是我所做的：替换   android.gms：play-services-ads with firebase：firebase-ads in below   文件：

build.gradle project.properties plugin.xml同时检查是否存在   版本是在android.gms：play-services-ads：X.X.X之后提供的   用android.gms替换它：play-services-ads：+

Answer 2

在将Ionic本机FCM插件添加到您的应用之前，您需要在Google Firebase控制台上配置您的应用，并将其添加到您应用的根文件夹中的GoogleService-info.plist和google-services.json。

尝试删除插件，添加文件，然后再次重新添加插件。
