How do I find if a root uri tree exist?-CodePudding

I get a tree uri from use folder, and want to know if folder exsist in case user deleted. I tried doc == null from treeUri and single, and also exists but they dont they both show not null when folder is deleted. Thanks

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 }

Try to list the content of the tree.

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