Determines the rate at which the elapsed time changes. Used to update the elapsed time and the progress bar. The seek bar is updated using the media session's playback state in a similar way: Media controls UI and corresponding metadata fields This screenshot shows how these metadata fields are displayed in the media controls. putLong(MediaMetadata.METADATA_KEY_DURATION, currentTrack.duration) // 4 indicator won't be shown on the seekbar. If duration isn't set, such as for live broadcasts, then the progress MediaMetadata.METADATA_KEY_ALBUM_ART_URI, currentTrack.albumArtUri) The URI scheme needs to be "content", "file", or "android.resource".
