↳ | 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
public static final String COLUMN_DISPLAY_NAME
Display name of a document, used as the primary title displayed to a user. This column is required.
Type: STRING
Constant Value: "_display_name"
COLUMN_DOCUMENT_ID
public static final String COLUMN_DOCUMENT_ID
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
Constant Value: "document_id"
COLUMN_FLAGS
public static final String COLUMN_FLAGS
Flags that apply to a document. This column is required.
Type: INTEGER (int)
See also:
FLAG_DIR_BLOCKS_OPEN_DOCUMENT_TREE
FLAG_DIR_PREFERS_GRID
FLAG_DIR_PREFERS_LAST_MODIFIED
FLAG_DIR_SUPPORTS_CREATE
FLAG_PARTIAL
FLAG_SUPPORTS_COPY
FLAG_SUPPORTS_DELETE
FLAG_SUPPORTS_METADATA
FLAG_SUPPORTS_MOVE
FLAG_SUPPORTS_REMOVE
FLAG_SUPPORTS_RENAME
FLAG_SUPPORTS_SETTINGS
FLAG_SUPPORTS_THUMBNAIL
FLAG_SUPPORTS_WRITE
FLAG_VIRTUAL_DOCUMENT
FLAG_WEB_LINKABLE
Constant Value: "flags"
COLUMN_ICON
public static final String COLUMN_ICON
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)
Constant Value: "icon"
COLUMN_LAST_MODIFIED
public static final String COLUMN_LAST_MODIFIED
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)
See also:
Constant Value: "last_modified"
COLUMN_MIME_TYPE
public static final String COLUMN_MIME_TYPE
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
See also:
Constant Value: "mime_type"
COLUMN_SIZE
public static final String COLUMN_SIZE
Size of a document, in bytes, or null
if unknown. This column
is required.
Type: INTEGER (long)
Constant Value: "_size"
COLUMN_SUMMARY
public static final String COLUMN_SUMMARY
Summary of a document, which may be shown to a user. This column is
optional, and may be null
.
Type: STRING
Constant Value: "summary"
FLAG_DIR_BLOCKS_OPEN_DOCUMENT_TREE
public static final int FLAG_DIR_BLOCKS_OPEN_DOCUMENT_TREE
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.
Constant Value: 32768 (0x00008000)
FLAG_DIR_PREFERS_GRID
public static final int FLAG_DIR_PREFERS_GRID
Flag indicating that a directory prefers its contents be shown in a
larger format grid. Usually suitable when a directory contains mostly
pictures. Only valid when COLUMN_MIME_TYPE
is
MIME_TYPE_DIR
.
See also:
Constant Value: 16 (0x00000010)
FLAG_DIR_PREFERS_LAST_MODIFIED
public static final int FLAG_DIR_PREFERS_LAST_MODIFIED
Flag indicating that a directory prefers its contents be sorted by
COLUMN_LAST_MODIFIED
. Only valid when
COLUMN_MIME_TYPE
is MIME_TYPE_DIR
.
See also:
Constant Value: 32 (0x00000020)
FLAG_DIR_SUPPORTS_CREATE
public static final int FLAG_DIR_SUPPORTS_CREATE
Flag indicating that a document is a directory that supports creation
of new files within it. Only valid when COLUMN_MIME_TYPE
is
MIME_TYPE_DIR
.
Constant Value: 8 (0x00000008)
FLAG_PARTIAL
public static final int FLAG_PARTIAL
Flag indicating that a document is not complete, likely its contents are being downloaded. Partial files cannot be opened, copied, moved in the UI. But they can be deleted and retried if they represent a failed download.
See also:
Constant Value: 8192 (0x00002000)
FLAG_SUPPORTS_COPY
public static final int FLAG_SUPPORTS_COPY
Flag indicating that a document can be copied to another location within the same document provider.

the calling application is granted both
Intent#FLAG_GRANT_READ_URI_PERMISSION
and
Intent#FLAG_GRANT_WRITE_URI_PERMISSION
. However, the actual
writability of a document may change over time, for example due to
remote access changes. This flag indicates that a document client can
expect ContentResolver#openOutputStream(Uri)
to succeed.
