Public constructors
Builder
Builder()
Create an empty Builder. Any field that should be included in the MediaMetadata must be added.
Builder
Builder(source: MediaMetadata!)
Create a Builder using a MediaMetadata instance to set the initial values. All fields in the source metadata will be included in the new metadata. Fields can be overwritten by adding the same key.
| Parameters | |

Public methods
build
fun build(): MediaMetadata!
Creates a MediaMetadata instance with the specified fields.
| Return | |
|---|---|
MediaMetadata! |

putBitmap
fun putBitmap(
key: String!,
value: Bitmap!
): MediaMetadata.Builder!
Put a Bitmap into the metadata. Custom keys may be used, but if the METADATA_KEYs defined in this class are used they may only be one of the following:
Large bitmaps may be scaled down by the system with Builder.setBitmapDimensionLimit(int) when MediaSession.setMetadata is called. To pass full resolution images Uris should be used with putString.
| Parameters | |
|---|---|
key |
String!: The key for referencing this value Value is android.media.MediaMetadata#METADATA_KEY_ART, android.media.MediaMetadata#METADATA_KEY_ALBUM_ART, or android.media.MediaMetadata#METADATA_KEY_DISPLAY_ICON |

setBitmapDimensionLimit
fun setBitmapDimensionLimit(bitmapDimensionLimit: Int): MediaMetadata.Builder
Sets the maximum width/height (in pixels) for the bitmaps in the metadata. Bitmaps will be replaced with scaled down copies if their width (or height) is larger than bitmapDimensionLimit.
In order to unset the limit, pass Integer.MAX_VALUE as bitmapDimensionLimit.
