Try to list the content of the tree.

If the tree does not exist anymore you will get an exception or a null cursor.

Did you try to do something like that? with the findFile() method?

Uri treeUri = uri;
DocumentFile root = DocumentFile.fromTreeUri(this, treeUri);
if (root.findFile("Foldername") == null) { //create folder }
