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 ACTION_OPEN_DOCUMENT and ACTION_CREATE_DOCUMENT .

Specific icon resource ID for a document. This column is optional, and may be null to use a platform-provided default icon based on COLUMN_MIME_TYPE .

Timestamp when a document was last modified, in milliseconds since January 1, 1970 00:00:00.0 UTC. This column is required, and may be null if unknown. A DocumentsProvider can update this field using events from ParcelFileDescriptor.OnCloseListener or other reliable ParcelFileDescriptor transports.
