我帮我找出问题所在。
嗨，我在安卓设备上运行Kivy MD应用程序时遇到问题。在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。应用程序已成功安装，并且加载kivy启动屏幕，但随后应用程序关闭。请注意我无法获得日志广播，因为我的手机无法连接使用"运行"(我尝试了很多方法，但这不是问题所在(

我写了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，从而简化了事情：下面是我运行的代码：

好的。所以这对我来说不起作用，有效的是添加kivy==2.0.0，kivymd==0.104.1
在buildozer.spec文件的需求行中，使用这个
requirements = python3,kivy==2.0.0,https://github.com/kivymd/KivyMd/archive/master.zip,pygments,sdl2_ttf==2.0.15,pillow,docutils,plyer
这对我有效。
