Remarks
Unique ID of a document. This ID is both provided by and interpreted by a DocumentsProvider, and should be treated as an opaque value by client applications. This column is required.
Each document must have a unique ID within a provider, but that single document may be included as a child of multiple directories.
A provider must always return durable IDs, since they will be used to issue long-term URI permission grants when an application interacts with Intent#ACTION_OPEN_DOCUMENT and Intent#ACTION_CREATE_DOCUMENT.
