Method Detail

- 

getMetadata

android.support.v4.media.MediaMetadataCompat getMetadata​([Player](../../Player.html "interface in com.google.android.exoplayer2")player)

Gets the MediaMetadataCompat to be published to the session.

An app may need to load metadata resources like artwork bitmaps asynchronously. In such a case the app should return a MediaMetadataCompat object that does not contain these resources as a placeholder. The app should start an asynchronous operation to download the bitmap and put it into a cache. Finally, the app should call MediaSessionConnector.invalidateMediaSessionMetadata(). This causes this callback to be called again and the app can now return a MediaMetadataCompat object with all the resources included.

Parameters:player - The player connected to the media session.Returns:The MediaMetadataCompat to be published to the session.

default boolean sameAs​(android.support.v4.media.MediaMetadataCompat oldMetadata,
                       android.support.v4.media.MediaMetadataCompat newMetadata)

Returns whether the old and the new metadata are considered the same.
