因此，当我尝试将Android平台添加到我的ionic项目中时，我收到以下错误。 这是一个现有的项目，我正在更新所使用的科尔多瓦版本，我尝试了各种版本的 android cordova，但所有这些版本都存在完全相同的问题，我在网上找不到任何东西，除了与黑莓有关的东西，我已经删除并重新添加了该平台几次但没有成功， 不断收到相同的错误：

到目前为止我尝试过的命令
ionic cordova platform add android@7.1.0
ionic cordova platform add android@6.4.0
ionic cordova platform add android@latest
ionic cordova platform add android

最后，我不得不卸载 cordova 和 ionic，从项目中删除平台，然后重新安装所有内容并重新添加平台以使其再次工作。
我遇到了同样的问题，并通过删除文件/platform/android/android.json解决了它。然后重新运行构建，一切正常!!
在Android Studio构建我的Cordova应用程序后，此错误已从控制台中消失。在黑匣子环境中Cordova，我发现，有时是与Android Studio/Xcode和CordovaCLI 断断续续地玩。令人惊讶的是，许多错误以这种方式消失了。
