Pytube/Pytube3 安装在 Android 设备上后无法与 kivy 一起使用 [使用 Buildozer 编译]

Question

我正在尝试制作一个应用程序，为我的第一个 kivy 项目下载 YouTube 视频。该程序在 Windows 10 上运行良好，但不适用于 Android。我相信我的问题归结为我是否使用了正确的 pytube 库（无论是“pytube”还是“pytube3”）。另外，有人知道如何为指定的导入正确设置 buildozer.spec 文件吗？

附言如何将 DownloadedVideos 文件夹包含到 buildozer.spec 中？

这是一个测试模型 BTW，所以代码改进来了 ;)
