With Android Q file interface can't be used to access public directories, unless you use the requestLegacyStorage in your app manifest (not raccomanded since it won't work anymore with Android R). To access the directory you need to use the DocumentFile class, for example:

DocumentFile f = DocumentFile.fromTreeUri(context, uri);
f.listFiles();
