Kivy/KivyMD 应用程序在编译为 .apk 后在 Android 崩溃
Kivy/KivyMD application crashes on Android after compiling to .apk
我是 Python 和 Kivy 的新手，所以请帮助我。
所以我想将我的应用程序编译为 .apk，并在 YouTube 上找到了一个指导视频。（顺便说一句，我正在使用 Windows）
在这里 - https://www.youtube.com/watch?v=D0reWInYl6k&ab_channel=SBDeveloper
所以，我在编辑的时候buildozer.spec发现作者没有设置最新的KivyMD版本，所以我设置了。
它编译成功，但是当我在我的 phone 上打开它时，它显示了 kivy 加载屏幕然后就崩溃了。
我搜索了很多问题是什么，但什么都不懂。
这里是 buildozer.spec 文件：

长版：
在做了很多 kivy 应用程序之后，我可以给你最好的建议：做“Hello World”（这意味着做尽可能小的工作代码）。实际上，如果没有错误消息，那么在没有所有信息的情况下崩溃的可能性很大，您的标题不是 Kivy/KivyMD 应用程序在编译为 .apk 后在 Android 上崩溃，而是 帮帮我 这很费时间...
问题：
- 在没有有效的 MVP 应用程序的情况下尝试导入那么多东西是疯狂的。
- 您正在导入 MD 的东西，这些东西发展很快，可以轻松地在一个版本上工作并在另一个版本上崩溃。
- 您正在使用存储而未在 buildozer 上询问。
- 即使您实际上在
build/on_kv_post 上崩溃，您也不会显示 python 代码。
- 您需要使用
buildozer -v android debug deploy run logcat 通过将 phone 连接到您的 PC 来查看错误。
如果你一步一步完成，你会从 Kivy/KivyMD 应用程序在编译到 .apk 后在 Android 上崩溃传递到类似的东西：
