【问题描述】：

我正在尝试在 android 模拟器中构建一个 Ionic 应用程序，但奇怪的是我无法构建该应用程序。当我运行 ionic cordova run android 构建失败并出现以下错误：

问题可能出在cordova-plugin-facebook4 上，因为它在我删除此插件时有效。我已按照插件页面中的 Android 指南说明进行操作，但不知道如何解决。有什么办法可以解决这个问题并使用这个插件吗？

离子：3.20.0
科尔多瓦：8.0.0
cordova-plugin-facebook4: 2.2.0

【问题讨论】：

ionic Cordova 和 facebook 插件的版本？
@NullPointer 添加了问题中的信息。
你有没有检查过平台目录下插件是否安装正确？同样添加插件后，在Android studio中打开项目n检查是否有编译时错误

标签： android facebook cordova ionic-framework cordova-plugins

【解决方案1】：

只需检查一个工作正常的特定版本1.7.4，因此请尝试使用以下命令

ionic cordova plugin add cordova-plugin-facebook4@1.7.4 --variable APP_ID="xxxxx" --variable APP_NAME="XXXX XXXX"
