I'm trying to switch to the DocumentFile API as Android doesn't allow using File API anymore...
When I select a folder, it returned URI is
content://com.android.externalstorage.documents/tree/primary%3AMedia%2FCamera%2FFreeTime
Now I'm calling
DocumentFile.fromTreeUri(this, uri)
to get the content of the folder. I want to keep a list of all the subfolders within
The 1st subfolder I found has the following URI
content://com.android.externalstorage.documents/tree/primary%3AMedia%2FCamera%2FFreeTime/document/primary%3AMedia%2FCamera%2FFreeTime%2F11
I need to save it so later on I can check the files within that folder
The problem is that when I try to call
DocumentFile.fromTreeUri(this, uri)
on this subfolder uri it returns a DocumentFile matching the parent folder of this subfolder
content://com.android.externalstorage.documents/tree/primary%3AMedia%2FCamera%2FFreeTime
How can I save the subfolder uri here so I can later on list this subfolder files?
Two things.
First: take persistable uri permission on the folder choosen by the user.
Second: a subfolder uri as you save it is no tree uri and hence you cannot create a DocumentFile with .fromTreeUri().
Instead use:
