Also, the new [createDocument()][8] method lets you create new documents or directories
anywhere under the subtree.
This example creates a new directory by following code:
```java
ContentResolver contentResolver = getActivity().getContentResolver();
Uri docUri = DocumentsContract.buildDocumentUriUsingTree(uri,
DocumentsContract.getTreeDocumentId(uri));
Uri directoryUri = DocumentsContract
.createDocument(contentResolver, docUri, Document.MIME_TYPE_DIR, directoryName);
