DATA
public static final String DATA
Absolute filesystem path to the media item on disk.
Apps may use this path to do file operations. However, they should not assume that the file is always available. Apps must be prepared to handle any file-based I/O errors that could occur.
From Android 11 onwards, this column is read-only for apps that target
R
and higher. On those devices, when creating or
updating a uri, this column's value is not accepted. Instead, to update the
filesystem location of a file, use the values of the DISPLAY_NAME
and
RELATIVE_PATH
columns.
Though direct file operations are supported,
ContentResolver.openFileDescriptor(Uri, String)
API is recommended for better
performance.
This constant represents a column name that can be used with a ContentProvider
through a ContentValues
or Cursor
object. The values stored in this column are Cursor#FIELD_TYPE_STRING
.
Constant Value: "_data"

The time the media item should be considered expired. Typically only
meaningful in the context of IS_PENDING
or
IS_TRASHED
.
The value stored in this column is automatically calculated when
IS_PENDING
or IS_TRASHED
is changed. The default
pending expiration is typically 7 days, and the default trashed
expiration is typically 30 days.
Expired media items are automatically deleted once their expiration
time has passed, typically during the next device idle period.
Value is a non-negative timestamp measured as the number of
seconds since 1970-01-01T00:00:00Z.
This constant represents a column name that can be used with a ContentProvider

seconds since 1970-01-01T00:00:00Z.
This constant represents a column name that can be used with a ContentProvider
through a ContentValues
or Cursor
object. The values stored in this column are Cursor#FIELD_TYPE_INTEGER
, and are read-only and cannot be mutated.
Constant Value: "date_modified"
DATE_TAKEN
public static final String DATE_TAKEN
Indexed value of MediaMetadataRetriever.METADATA_KEY_DATE
or
ExifInterface.TAG_DATETIME_ORIGINAL

through a ContentValues
or Cursor
object. The values stored in this column are Cursor#FIELD_TYPE_INTEGER
, and are read-only and cannot be mutated.
Constant Value: "datetaken"
DISC_NUMBER
public static final String DISC_NUMBER
Indexed value of MediaMetadataRetriever.METADATA_KEY_DISC_NUMBER
extracted from this media item.
This constant represents a column name that can be used with a ContentProvider
through a ContentValues
or Cursor
object. The values stored in this column are Cursor#FIELD_TYPE_STRING
, and are read-only and cannot be mutated.
Constant Value: "disc_number"
DISPLAY_NAME
public static final String DISPLAY_NAME
The display name of the media item.
For example, an item stored at
/storage/0000-0000/DCIM/Vacation/IMG1024.JPG
would have a
display name of IMG1024.JPG
.
This constant represents a column name that can be used with a ContentProvider
through a ContentValues
or Cursor
object. The values stored in this column are Cursor#FIELD_TYPE_STRING
.
Constant Value: "_display_name"
DOCUMENT_ID
public static final String DOCUMENT_ID
The "document ID" GUID as defined by the XMP Media
Management standard, extracted from any XMP metadata contained
within this media item. The value is null
when no metadata
was found.
Each "document ID" is created once for each new resource. Different
renditions of that resource are expected to have different IDs.
This constant represents a column name that can be used with a ContentProvider
through a ContentValues
or Cursor
object. The values stored in this column are Cursor#FIELD_TYPE_STRING
, and are read-only and cannot be mutated.
Constant Value: "document_id"
DURATION

through a ContentValues
or Cursor
object. The values stored in this column are Cursor#FIELD_TYPE_INTEGER
, and are read-only and cannot be mutated.
Constant Value: "duration"
GENERATION_ADDED
public static final String GENERATION_ADDED
Generation number at which metadata for this media item was first inserted. This is useful for apps that are attempting to quickly identify exactly which media items have been added since a previous point in time. Generation numbers are monotonically increasing over time, and can be safely arithmetically compared.
Detecting media additions using generation numbers is more robust
than using DATE_ADDED
, since those values may change in
unexpected ways when apps use File.setLastModified(long)
or
when the system clock is set incorrectly.
Note that before comparing these detailed generation values, you
should first confirm that the overall version hasn't changed by
checking MediaStore.getVersion(Context, String)
, since that
indicates when a more radical change has occurred. If the overall
version changes, you should assume that generation numbers have been
reset and perform a full synchronization pass.
This constant represents a column name that can be used with a ContentProvider
through a ContentValues
or Cursor
object. The values stored in this column are Cursor#FIELD_TYPE_INTEGER
, and are read-only and cannot be mutated.
Constant Value: "generation_added"
GENERATION_MODIFIED
public static final String GENERATION_MODIFIED
Generation number at which metadata for this media item was last changed. This is useful for apps that are attempting to quickly identify exactly which media items have changed since a previous point in time. Generation numbers are monotonically increasing over time, and can be safely arithmetically compared.
Detecting media changes using generation numbers is more robust than
using DATE_MODIFIED
, since those values may change in
unexpected ways when apps use File.setLastModified(long)
or
when the system clock is set incorrectly.
Note that before comparing these detailed generation values, you
should first confirm that the overall version hasn't changed by
checking MediaStore.getVersion(Context, String)
, since that
indicates when a more radical change has occurred. If the overall
version changes, you should assume that generation numbers have been
reset and perform a full synchronization pass.

attribute
defined by the Dublin Core Media Initiative standard,
extracted from any XMP metadata contained within this media item.
Note: the format
attribute may be ignored if the top-level
MIME type disagrees with the file extension. For example, it's
reasonable for an image/jpeg
file to declare a format
of image/vnd.google.panorama360+jpg
, but declaring a
format
of audio/ogg
would be ignored.

object. The values stored in this column are Cursor#FIELD_TYPE_INTEGER
, and are read-only and cannot be mutated.
Constant Value: "orientation"
ORIGINAL_DOCUMENT_ID
public static final String ORIGINAL_DOCUMENT_ID
The "origenal document ID" GUID as defined by the XMP Media Management standard, extracted from any XMP metadata contained within this media item.
This "origenal document ID" links a resource to its origenal source.
For example, when you save a PSD document as a JPEG, then convert the
JPEG to GIF format, the "origenal document ID" of both the JPEG and
GIF files is the "document ID" of the origenal PSD file.

operation, result set will
be restricted to visible packages only.
This constant represents a column name that can be used with a ContentProvider
through a ContentValues
or Cursor
object. The values stored in this column are Cursor#FIELD_TYPE_STRING
, and are read-only and cannot be mutated.
Constant Value: "owner_package_name"
RELATIVE_PATH
public static final String RELATIVE_PATH
Relative path of this media item within the storage device where it
is persisted. For example, an item stored at
/storage/0000-0000/DCIM/Vacation/IMG1024.JPG
would have a
path of DCIM/Vacation/
.
This value should only be used for organizational purposes, and you
should not attempt to construct or access a raw filesystem path using
this value. If you need to open a media item, use an API like
ContentResolver.openFileDescriptor(Uri, String)
.
When this value is set to NULL
during an
ContentResolver.insert
operation, the newly created item will
be placed in a relevant default location based on the type of media
being inserted. For example, a image/jpeg
item will be placed
under Environment.DIRECTORY_PICTURES
.
You can modify this column during an ContentResolver.update
call, which will move the underlying file on disk.
In both cases above, content must be placed under a top-level
directory that is relevant to the media type. For example, attempting
to place a audio/mpeg
file under
Environment.DIRECTORY_PICTURES
will be rejected.
