應用程序在 buildozer android 調試中崩潰 - 沒有名為“kivy._event”的模塊

Question

我構建了一個 KivyMD 應用程序，在 pycharm 中工作。 當我在 linux 的 buildozer 中為 android 編譯時，它啟動然后崩潰。 這是說明沒有名為 kivy._event 的模塊的日志。 我注意到屏幕管理器引用的 kivy/uix 文件夾中有一個 _event.pxd。 希望有人可以提供幫助。 非常感謝。

我研究並嘗試了一些東西。 最后我能夠克服這一點。 大多數帖子說構建有一些問題。 我建議您刪除 Ubuntu 中 App 文件夾中的 .buildozer 文件夾。 重新安裝 kivy、cython 和所有依賴項。

https://buildozer.readthedocs.io/en/stable/installation.html

其次，在 buildozer.spec 文件中的要求。 我在 Github 中指定了 kivymd 主鏈接。 你可以試試這兩個。

requirements = kivy==2.1.0, kivymd==1.0.2, sdl2_ttf == 2.0.15, pillow

或者

requirements = kivy==2.1.0, https://github.com/kivymd/KivyMD/archive/master.zip, sdl2_ttf == 2.0.15, pillow

如果您仍然有modulenotfounderror，我建議您在kivy 或kivymd 文件夾中找到py 文件，將代碼復制到與您的main.py 相同的文件夾中另一個不同名稱的新py 文件中，將class 導入您的main.py。 我懷疑在構建過程中存在一些 py 文件未正確添加的錯誤。
