When sending a MediaItem to a MediaSession with a Media3 MediaController important information is removed for privacy reason. To look up the fully populated MediaItem the mediaId is used as a key. Hence having the mediaId marhalled to the JSON representation that is sent to a Cast device enables app developers to use the same look up facilities. #minor-release PiperOrigin-RevId: 420022868
Cast module
This module provides a Player implementation that controls a Cast receiver app.
Getting the module
The easiest way to get the module is to add it as a gradle dependency:
implementation 'androidx.media3:media3-cast:1.X.X'
where 1.X.X
is the version, which must match the version of the other media
modules being used.
Alternatively, you can clone this GitHub project and depend on the module locally. Instructions for doing this can be found in the top level README.
Using the module
Create a CastPlayer
and use it to control a Cast receiver app. Since
CastPlayer
implements the Player
interface, it can be passed to all media
components that accept a Player
, including the UI components provided by the
UI module.
