我尝试了多种方法使用kivy（JiCsingApp，以保留以前的数据）在文档中创建目录，但不知怎的，似乎没有一个是正确的，我总是收到错误：[Errno 13]权限被拒绝。如果有人能帮助我解决这个问题，我将不胜感激。如果我创建一个简单的文件，我也会收到错误消息。如果我手动授予权限，程序运行不会出错。
Python 来了：

这是我的 buildozer.spec 文件（据我所知相关部分）：
requirements = plyer, jnius, kivy, https://github.com/kivymd/kivymd/archive/master.zip ...
...
# (list) Permissions
# (See https://python-for-android.readthedocs.io/en/latest/buildoptions/#build-options-1 for all the supported syntaxes and properties)
# android.permissions = android.permission.INTERNET, (name=android.permission.WRITE_EXTERNAL_STORAGE;maxSdkVersion=18)
android.permissions = android.permission.INTERNET, android.permission.WRITE_EXTERNAL_STORAGE,android.permission.READ_EXTERNAL_STORAGE, android.permission.MANAGE_EXTERNAL_STORAGE
感谢任何可以提前提供帮助的人！
您的应用程序的文件访问问题可能与 Android 的较新存储策略有关。通过确保您遵循 Android 10+ 的分区存储实践并使用正确的权限（例如 Android 11+ 的 MANAGE_EXTERNAL_STORAGE），您应该能够解决权限被拒绝的错误。
