Attributes

Remarks

Build URI representing the target Document#COLUMN_DOCUMENT_ID in a document provider. When queried, a provider will return a single row with columns defined by Document.

However, instead of directly accessing the target document, the returned URI will leverage access granted through a subtree URI, typically returned by Intent#ACTION_OPEN_DOCUMENT_TREE. The target document must be a descendant (child, grandchild, etc) of the subtree.

This is typically used to access documents under a user-selected directory tree, since it doesn't require the user to separately confirm each new document access.
