Question

我需要将Ionic应用程序连接到FCM的帮助。在实时数据库中创建条目时，我需要发送推送通知。我尝试了以下方法：

但是，当我尝试将其部署到设备或构建应用程序时，上述所有方法都会给我带来错误，

任务'：processDebugGoogleServices'的执行失败。

任何想法如何进行？我很可能没有正确配置Firebase。我已经将google-services.json放在了根目录中，在那里没有问题。

非常感谢您的帮助。

尝试在fcm插件目录下更改此文件

/plugins/cordova-plugin-fcm/src/android/FCMPlugin.gradle

buildscript {
    repositories {
            jcenter()
            mavenLocal()
        }
    dependencies {
        classpath 'com.android.tools.build:gradle:+'
        classpath 'com.google.gms:google-services:3.0.0'
    }
}
// apply plugin: 'com.google.gms.google-services'
// class must be used instead of id(string) to be able to apply plugin from non-root gradle file
// apply plugin: com.google.gms.googleservices.GoogleServicesPlugin
ext.postBuildExtras = {
    apply plugin: com.google.gms.googleservices.GoogleServicesPlugin
}

然后

ionic cordova platform rm android
ionic cordova platform add android

然后更改此文件 /platforms/android/project.properties
