我在使用**kivy和kivymd**开发python应用程序方面相当新。我一直在开发一款个人应用程序，将用来存储日常开支。我使用的是MySQL云数据库。Python程序在Windows上运行得非常好，就像我想要的那样。为了测试的目的，并确保kivy实际上可以在android上工作，我用kivy和kivymd在python中创建了一个“Hello World”显示应用程序，并使用GoogleColab中的Buildozer将其转换为apk文件，以便在我的android设备上进行测试。它在我所有运行不同Android版本的设备上都运行得很好。我已经创建了帐户跟踪应用程序，并以类似的方式在谷歌可乐我转换成apk文件。我在我的设备上测试了这个应用程序，它在加载屏幕上崩溃了。但令人惊讶的是，它在我拥有的另一台Android设备上运行得很好。
器械1的质量标准（应用程序崩溃）：
- 型号：realme 9 5G极速版
- Android版本：13.
设备2的规范（应用程序工作）：
- 型号：Samsung Galaxy M30 s，
- Android版本：11.
**简单的“Hello World”应用程序在上述两种设备上都运行得非常好。
我在Google Drive链接中提供了我的帐户应用程序的源代码，因为它是一个大文件。虽然它不会在其他Windows设备上运行，直到和除非python mysql连接器被安装和配置，并且默认数据库被馈送到该系统。

注意：-出于安全和隐私的原因，我已经将Python文件中的MySQL服务器连接配置从托管服务器更改为本地主机。但我的应用程序是使用配置为与我的托管服务器数据库一起使用的连接构建的。
我在Android Studio中使用了logcat，并连接了我的移动的以获取错误/崩溃日志。

at com.android.server.wm.WindowState.notifyInsetsControlChanged(WindowState.java:4288)据我从回溯的错误崩溃日志中了解到，在我的设备上很少有库是不可读的。但是，如果Google Colab创建了一个损坏的apk，那么它应该在每台设备上崩溃。但它在其他设备上工作（更不用说布局被破坏了，但那是另一天的另一个故障排除）
在做我的resarch关于故障排除，我知道错误可能是因为较低的targetSDK。显然Buildozer使用API-31创建了apk。由于我的设备运行在Android 13上，因此需要33以上的目标SDK。所以，在做了必要的更改后（使用API-34），我再次创建了apk，它再次崩溃，给出了logcat上相同的错误日志。

请帮助我，它已经快一个星期了，我困在这个问题试图弄清楚。否则我想放弃它，重新开始。但是我真的很想用python，因为我对python有很好的经验和知识。
