class Document

kotlin.Any
↳	android.provider.DocumentsContract.Document

Constants related to a document, including Cursor column names and flags.

A document can be either an openable stream (with a specific MIME type), or a directory containing additional documents (with the MIME_TYPE_DIR MIME type). A directory represents the top of a subtree containing zero or more documents, which can recursively contain even more documents and directories.

All columns are read-only to client applications.

Constants

COLUMN_DISPLAY_NAME

Added in API level 19

static val COLUMN_DISPLAY_NAME: String

Display name of a document, used as the primary title displayed to a user. This column is required.

Type: STRING

Value: "_display_name"

COLUMN_DOCUMENT_ID

Added in API level 19

static val COLUMN_DOCUMENT_ID: String

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.

Type: STRING

Value: "document_id"

COLUMN_FLAGS

Added in API level 19

static val COLUMN_FLAGS: String

Flags that apply to a document. This column is required.

Type: INTEGER (int)

Value: "flags"

COLUMN_ICON

Added in API level 19

static val COLUMN_ICON: String

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.

Type: INTEGER (int)

Value: "icon"

COLUMN_LAST_MODIFIED

Added in API level 19

static val COLUMN_LAST_MODIFIED: String

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 OnCloseListener or other reliable ParcelFileDescriptor transports.

Type: INTEGER (long)

Value: "last_modified"

See Also

• java.lang.System#currentTimeMillis()

COLUMN_MIME_TYPE

Added in API level 19

static val COLUMN_MIME_TYPE: String

Concrete MIME type of a document. For example, "image/png" or "application/pdf" for openable files. A document can also be a directory containing additional documents, which is represented with the MIME_TYPE_DIR MIME type. This column is required.

Type: STRING

Value: "mime_type"

See Also

• #MIME_TYPE_DIR

COLUMN_SIZE

Added in API level 19

static val COLUMN_SIZE: String

Size of a document, in bytes, or null if unknown. This column is required.

Type: INTEGER (long)

Value: "_size"

COLUMN_SUMMARY

Added in API level 19

static val COLUMN_SUMMARY: String

Summary of a document, which may be shown to a user. This column is optional, and may be null.

Type: STRING

Value: "summary"

FLAG_DIR_BLOCKS_OPEN_DOCUMENT_TREE

Added in API level 30

static val FLAG_DIR_BLOCKS_OPEN_DOCUMENT_TREE: Int

Flag indicating that a document is a directory that wants to block itself from being selected when the user launches an Intent.ACTION_OPEN_DOCUMENT_TREE intent. Individual files can still be selected when launched via other intents like Intent.ACTION_OPEN_DOCUMENT and Intent.ACTION_GET_CONTENT. Only valid when COLUMN_MIME_TYPE is MIME_TYPE_DIR.

Note that this flag only applies to the single directory to which it is applied. It does not block the user from selecting either a parent or child directory during an Intent.ACTION_OPEN_DOCUMENT_TREE request. In particular, the only way to guarantee that a specific directory can never be granted via an Intent.ACTION_OPEN_DOCUMENT_TREE request is to ensure that both it and all of its parent directories have set this flag.

Value: 32768

• android.content.Intent#ACTION_OPEN_DOCUMENT_TREE
• #COLUMN_FLAGS

FLAG_DIR_PREFERS_GRID

Added in API level 19
