Example 11 with ControllerInfo

use of androidx.media3.session.MediaSession.ControllerInfo in project media by androidx.

the class MediaLibrarySessionImpl method onSubscribeOnHandler.

    // to call notifyChildrenChanged() in the callback.
    // 
    // onSubscribe is defined to return a non-null result but it's implemented by applications,
    // so we explicitly null-check the result to fail early if an app accidentally returns null.
