getMetadata
public android.support.v4.media.MediaMetadataCompat getMetadata(Player player)
Description copied from interface:MediaSessionConnector.MediaMetadataProviderGets theMediaMetadataCompatto 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
MediaMetadataCompatobject 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 callMediaSessionConnector.invalidateMediaSessionMetadata(). This causes this callback to be called again and the app can now return aMediaMetadataCompatobject with all the resources included.- Specified by:
getMetadatain interfaceMediaSessionConnector.MediaMetadataProvider- Parameters:
player- The player connected to the media session.- Returns:
- The
MediaMetadataCompatto be published to the session.
