我是编程新手。我从来没有编码过，但在 IA 的帮助下，我想从用 Kivy 编写的 Python 代码创建一个 apk。
这是我的脚本：

代码与“briefcase dev”完美运行
当我尝试构建 android aab 文件时，我被卡住了。
我尝试过“公文包”和“buildozer”。而我却一事无成。
在我上次的尝试中，我遇到了这个错误：

我尝试删除所有内容并重新安装。
我在 Windows 中尝试过相同的过程。
有虚拟环境但没有...
首先，确保在Windows上测试您的应用程序，以确保顺利运行，不会出现错误。然后，探索使用 Buildozer 作为构建工具，并参考其文档以获取指导。如果您只专注于 Android 测试，请首先创建一个带有 GUI 的简单应用程序，因为在不使用 GUI 的情况下尝试可能会导致大量错误，这些错误可能会令人难以承受。
