Hi, I am trying to allow my app to read and write files to the public Documents folder. This works fine in the app if I create a file there I can read it.
However the issue is, I need my app to be able to read files there that are copied over from a PC. Users need to be able to copy files back and forth to their PC through File Explorer, but anything copied to the Documents folder on Android are not visible to the app. How can I allow this? Write External Storage permission is given but does not seem to help.
I used Android.OS.Environment.GetExternalStoragePublicDirectory(Android.OS.Environment.DirectoryDocuments)
It is deprecated so is that an issue? Is there a newer call that will give me the access I need?

2022-06-06T05:14:40.173+00:00 This still does not really tell me how I can access a file copied over from a PC via USB connection, at least not that I can find.
I need to know if that is even possible anymore? Other apps like Acrobat seem to be able to read files copied there without issue. -

The only way is to use manage external storagehttps://developer.android.com/training/data-storage/manage-all-files
but you could have problems with the store...

2022-06-06T15:09:58.947+00:00 There must be a way, I can copy a pdf document from my PC to Documents on my android and Adobe or moon reader can see and open it fine, but they don't ask for the manage all files permission.

Anonymous2022-06-14T09:09:38.837+00:00 You can refer to this way to request MANAGE_EXTERNAL_STORAGE permission https://developer.android.com/training/data-storage/manage-all-files#all-files-access
