Android 离子5与FCM

我尝试使用电容器将FCM添加到我的应用程序中

我将google servies.json添加到android\app

我更改代码 从

classpath'com.google.gms:googleservices:4.3.3'

到

classpath'com.google.gms:googleservices:4.3.4'

作为firebase文档

buildscript {
    
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.6.1'
        classpath 'com.google.gms:google-services:4.3.4'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

apply from: "variables.gradle"

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

尝试在模拟器中运行应用程序，但在android studio中出现错误

File google-services.json is missing. The Google Services Plugin cannot function without it.

根据show your的问题，几个月前我也遇到了同样的问题，我用 以下步骤

1） 。首先，从项目中删除fcm插件

2） 。从firebase控制台下载google-services.json文件

3） 。将google-services.json文件放在项目的根文件夹中

4） 。也放在platform/android/文件夹中

然后安装fcm插件，清理构建并重新构建

这个过程对我来说很有效，如果不起作用，那么也可以参考下面的链接，它对我和你都有帮助

谢谢Mayank，这是因为我使用了电容器，这台FCM仅在cordova工作，okk，这个例子可能有助于FCM在ionic与电容器的集成，祝您愉快！！iOS有问题，有人知道如何解决吗？嗨，@M.Mariscal您能否在此处添加更多信息，了解您面临的问题类型，以便我们可以方便地为您提供帮助或指导。/Users/manel/Documents/ionic_projects/project/platforms/ios/ProjectApp/Plugins/cordova plugin fcm with dependency updated/AppDelegate+FCMPlugin.M:146:101:空性说明符“nonnull”与上的现有说明符“nullable”冲突当我尝试构建（带角度的离子5）时，XCode上的错误是否存在？您使用的是cordova还是电容器？如果您正在使用电容器插件，这就解决了我的问题。
