如何解决kivyMD APK 在启动时崩溃 (android)
我帮我弄清楚可能是什么问题。
嗨，我在 Android 设备上运行 Kivy MD 应用程序时遇到问题。 将我的应用程序编译成 apk 后，我使用 U 盘传输 文件到安卓手机上。该应用程序已成功安装并 加载 kivy 启动画面，但随后应用程序关闭。请注意 我无法获得 logcast 因为我的手机无法连接 使用“运行”（我尝试了很多方法，但这不是问题）

我通过编写一个简单的代码来运行以查看问题是否与我最初的复杂代码有关：我运行的代码如下：

- 这是我在命令提示符（windows）中成功运行我的应用程序时得到的日志
This is the log i get when i successfully ran my app in comand prompt(windows)
解决方法
好的。所以这对我不起作用，添加 kivy==2.0.0,kivymd==0.104.1
