Ability to use MANAGE_EXTERNAL_STORAGE in Android

[KamilSucharski]

The current way of android file retrieval returns URIs like "content://", and from that I can use the MediaStore to get a synthetic file path, or create a file descriptor. Unfortunately, In my project, I need to satisfy a few requirements:

1. Ability to know the actual file path.
2. Ability to access the file path even after app restart or phone restart.
3. Copying the files to internal storage is not an option (huge files).
4. Target new Android versions.

I think the only realistic option left is to use the MANAGE_EXTERNAL_STORAGE permission (setting Google Play policy aside). But even if I have that granted, the library still returns those permission-less paths. Most likely the library would need to handle the file picking itself differently to be compatible with this option?
