Answer 1

我有同样的问题和几乎相同的设置。您是否尝试将project_name > templates > app_name > template_name.html恢复为1.7.4版本？

对我而言，这不是一个解决方案，但它现在是一种解决方法，只是为了构建应用程序。

如果还原插件会为您修复，请查看https://github.com/phonegap/phonegap-plugin-barcodescanner/issues/535。

Answer 2

转到平台 - ＆gt; android - ＆gt; build.gradle

在defaultConfig下添加multiDexEnabled true，如下所示

defaultConfig {
    multiDexEnabled true
}

这对我有用..
