How can I find hidden files?

[nikmax42]

I developing a gallery app and then I want to access images and video files, including those located in hidden .folders. It looks like MediaStore doesn't allow access to hidden media, so I'm using DocumentFileCompat. It finds hidden folder itself, but not finds content within. It looks like folder is empty, but it's actually not. How can I solve this?

Example
Creating two directories inside /storage/emulated/0/Download and put image.jpg inside:

1. /storage/emulated/0/Download/normal/image.jpg
2. /storage/emulated/0/Download/.hidden/image.jpg

Then do

val files = DocumentFileCompat.fromSimplePath(
                context = context, basePath = "",
                documentType = DocumentFileType.FILE
            )

and watch in debugger what we have:

Library found picture inside normal folder, bot not inside .hidden one.

After research of mediastore database (in my case it locates at /data/data/com.android.providers.media.module/databases/external.db) I noticed that hidden files not caching in Images and Videos tables, but only in Files table. So there is necessary to have full access to shared storage, not just Photos and Videos, to get access inside hidden folders. After I granted MANAGE_EXTERNAL_STORAGE permission it start working. My fault.
