Android 11 和文件 API 支持

以下文章提到 Android 11 允许使用 File API（在标题使用直接文件路径和本机库访问文件下）。

https://developer.android.com/about/versions/11/privacy/存储

我想了解更多有关此的信息。这是指MANAGE_EXTERNAL_STORAGE 权限还是笼统地说。如果它并不意味着 MANAGE_EXTERNAL_STORAGE 权限，那么它究竟意味着什么？

如果我使用存储访问框架来保留路径。持久化后，我可以使用 File 类在该持久路径中使用 File 类创建和保存文件吗？例如：

 File file = new File(filePath);
 FileOutputStream os = new FileOutputStream(file, false);
 OutputStreamWriter out = new OutputStreamWriter(os);
 out.write(downloadedSubtitles);
 out.close();

我可以使用 File 类读取持久路径中的文件吗？
我可以使用 file:// 路径吗？

我也有不同的相关问题。我可以使用 File 类和上面的代码将文件写入应用程序的文件夹吗？

谢谢。

The following article mentions that Android 11 allows for usage of the File API (under the title Access files using direct file paths and native libraries).

I would like more information on this. Does this refer to MANAGE_EXTERNAL_STORAGE permission or does it speak in general. If it does not mean MANAGE_EXTERNAL_STORAGE permission then what does it mean exactly?

If I use Storage Access Framework to persist a path. After persistence, can I use the File class to create and save a file in that persistent path using the File class? For example:

 File file = new File(filePath);
 FileOutputStream os = new FileOutputStream(file, false);
 OutputStreamWriter out = new OutputStreamWriter(os);
 out.write(downloadedSubtitles);
 out.close();
