buildozer 构建了 apk，但在 android 上不起作用

问题描述

您好，我已经使用以下命令构建了 apk：

请帮帮我！！我不明白这个问题。 我已经构建了 apk 并运行，但在启动时崩溃。 昨天应用程序正在运行，在我更改了规范文件并收到此错误之后。我将规范文件重写为原始文件，但错误始终存在

唯一不同的是我更新了 ubuntu 20.04 lts、应用程序和内核。

我尝试删除 .buildozer 文件夹和 .spec 文件

之后：

构建器初始化和 添加需求

# (list) Application requirements
# comma separated e.g. requirements = sqlite3,kivy
requirements = android,python3==3.8.5,kivy==master,https://github.com/kivymd/KivyMD/archive/master.zip,pygments,sdl2_ttf==2.0.15,jnius,pyjnius,plyer,pillow,xclip,xsel

解决方法

width: root.lbl_txt.texture_size[0] + dp(24) ?

,

这是 KivyMD 和/或您自己的代码中的一个错误，由 Kivy master 的最近更改所揭示。使用最新的 Kivy 版本，或等待 Kivy MD 中的修复。
