Answer 1

我有同样的问题，几乎相同的设置。您是否尝试将cordova-plugin-facebook4恢复到版本1.7.4？

对我来说，这不是一个解决方法，但现在是一种解决方法，只是为了让应用程序建立。

如果还原插件修复它，也可以看看https://github.com/phonegap/phonegap-plugin-barcodescanner/issues/535。

Answer 2

进入平台 - > Android的 - >的build.gradle

defaultConfig下添加multiDexEnabled true这样

defaultConfig { 
    multiDexEnabled true 
} 

这个工作对我..
