'How can I check if treeUri is empty?

I want to check if a treeUri has any files in it or if its empty, so I can delete the Folder. Ive tried listFiles but comes up with Landrodix.etc. and not the actual list. Thanks.

On Folder select

Intent intent = new 
Intent(Intent.ACTION_OPEN_DOCUMENT_TREE);
startActivityForResult(intent, 42);

Activity Result

DocumentFile dfile =
DocumentFile.fromTreeUri(this, uri);
DocumentFile[] de = dfile.listFiles();
st = de.toString();
javaandroidlisturi

I figured it out

Uri uri = Uri.parse(muri); 
DocumentFile directory = 
DocumentFile.fromTreeUri(this, uri);
DocumentFile[] files = 
directory.listFiles();
double w3 =  
Double.parseDouble(Integer.toString
(files3.length));

feel free to use this code no credits required it just .length
