FPDF2 无法与 Android 上的 Kivy 和 KivyMD 很好地配合

Question

我有一个可以生成 pdf 发票的应用程序，它是使用 python3 构建的，它使用 kivy、kivyMD 和 fpdf2。当我将其转换为 apk 并在 android 上运行时，它崩溃了。当我查看日志时，发现以下错误

再进一步我发现了这个错误

我也尝试在 buildozer 规范文件中添加 fonttools，但仍然遇到相同的错误

requirements = python3,kivy==2.2.1,kivymd==1.1.1,fpdf2,fonttools,pillow

fontTools 与 android 不兼容吗？

当我使用 fpdf 而不是 fpdf2 时，该应用程序可以工作，但随后我无法使用 fpdf2 的表格功能，这很糟糕！

有办法解决这个错误吗？

谢谢

Answer 1

而不是使用

requirements=fonttools

使用

requirements=https://github.com/fonttools/fonttools/archive/refs/heads/main.zip

这将解决你的问题
