The album title for the media.
The artwork for the album of the media's original source as a
Bitmap.
The artwork should be relatively small and may be scaled down by the
system if it is too large. For higher resolution artwork
METADATA_KEY_ALBUM_ART_URI should be used instead.
The artist for the album of the media's original source.
The artwork for the album of the media's original source as a Uri
formatted String. The artwork can be loaded using a combination of
openInputStream(Uri) and
decodeStream(InputStream).
For the best results, Uris should use the content:// style and support
EXTRA_SIZE for retrieving scaled artwork through
openTypedAssetFileDescriptor(Uri, String, Bundle).
The artwork for the media as a Bitmap.
The artwork should be relatively small and may be scaled down by the
system if it is too large. For higher resolution artwork
METADATA_KEY_ART_URI should be used instead.
The artist of the media.
The artwork for the media as a Uri formatted String. The artwork can be
loaded using a combination of openInputStream(Uri) and
decodeStream(InputStream).
For the best results, Uris should use the content:// style and support
EXTRA_SIZE for retrieving scaled artwork through
openTypedAssetFileDescriptor(Uri, String, Bundle).
The author of the media.
The compilation status of the media.
The composer of the media.
The date the media was created or published. The format is unspecified but RFC 3339 is recommended.
The disc number for the media's original source.
A description that is suitable for display to the user. When displaying more information for media described by this metadata this should be preferred to other fields if present.
An icon or thumbnail that is suitable for display to the user. When
displaying an icon for media described by this metadata this should be
preferred to other fields if present. This must be a Bitmap.
The icon should be relatively small and may be scaled down by the system
if it is too large. For higher resolution artwork
METADATA_KEY_DISPLAY_ICON_URI should be used instead.
A Uri formatted String for an icon or thumbnail that is suitable for
display to the user. When displaying more information for media described
by this metadata the display description should be preferred to other
fields when present. The icon can be loaded using a combination of
openInputStream(Uri) and
decodeStream(InputStream).
For the best results, Uris should use the content:// style and support
EXTRA_SIZE for retrieving scaled artwork through
openTypedAssetFileDescriptor(Uri, String, Bundle).
A subtitle that is suitable for display to the user. When displaying a second line for media described by this metadata this should be preferred to other fields if present.
A title that is suitable for display to the user. This will generally be
the same as METADATA_KEY_TITLE but may differ for some formats.
When displaying media described by this metadata this should be preferred
if present.
The duration of the media in ms. A negative duration indicates that the duration is unknown (or infinite).
The genre of the media.
A String key for identifying the content. This value is specific to the
service providing the content. If used, this should be a persistent
unique key for the underlying content. It may be used with
playFromMediaId(String, Bundle)
to initiate playback when provided by a MediaBrowser connected to
the same app.
The number of tracks in the media's original source.
The title of the media.
The track number for the media.
The user's rating for the media.
The writer of the media.
The year the media was created or published as a long.
