Not able to build and run an ionic and cordova based app on Android
我有一个非常基本的 Ionic 应用程序，我正在尝试构建 运行 在 Win 10 机器上。但是当我 运行 此命令时出现以下错误。不确定是否缺少其他内容，因为我对 NodeJS 和 Android 技术还很陌生。

安装后 Android Studio 安装了所有必需的工具和插件（下面的屏幕截图）
您的路径中缺少 android sdk 目录。
如果您查看 Cordova 需求日志，它会显示 'android' is not recognized as an internal or external command
因此，您需要在系统路径中安装 android SDK 的任何地方添加 tools 和 platform-tools。
找到解决方案。
所以这里有两个问题：
不正确的 ANDROID_HOME 环境变量值。这不应指向您的安装位置 android。 AppData 是 Win 中的隐藏文件夹，因此您需要找到它，然后指向正确的路径
ANDROID_HOME = C:\Users\nital\AppData\Local\Android\Sdk
未将 PATH 环境变量指向位于 Sdk 文件夹
中的 platform_tools 和 tools 文件夹
PATH = C:\Users\nital\AppData\Local\Android\Sdk\platform-tools
