Class SessionCallbackBuilder.DefaultAllowedCommandProvider

  • All Implemented Interfaces:
    SessionCallbackBuilder.AllowedCommandProvider
    Enclosing class:
    SessionCallbackBuilder
    public static final class SessionCallbackBuilder.DefaultAllowedCommandProvider
extends Object
implements SessionCallbackBuilder.AllowedCommandProvider
    Default implementation of SessionCallbackBuilder.AllowedCommandProvider that behaves as follows:
    • Accepts connection requests from controller if any of the following conditions are met:
      • Controller is in the same package as the session.
      • Controller is allowed via setTrustedPackageNames(List).
      • Controller has package name MediaSessionManager.RemoteUserInfo.LEGACY_CONTROLLER. See package name limitation for details.
      • Controller is trusted (i.e. has MEDIA_CONTENT_CONTROL permission or has enabled notification manager).
    • Allows all commands that the current player can handle.
    • Accepts all command requests for allowed commands.

    Note: this implementation matches the behavior of the ExoPlayer MediaSession extension and MediaSessionCompat.

        Description copied from interface: SessionCallbackBuilder.AllowedCommandProvider
        Called to query allowed commands in following cases:
        • A MediaController requests to connect, and allowed commands is required to tell initial allowed commands.
        • Underlying SessionPlayer state changes, and allowed commands may be updated via MediaSession.setAllowedCommands(androidx.media2.session.MediaSession.ControllerInfo, androidx.media2.session.SessionCommandGroup).

        The provided baseAllowedSessionCommand is built automatically based on the state of the SessionPlayer, SessionCallbackBuilder.RatingCallback, SessionCallbackBuilder.MediaItemProvider, SessionCallbackBuilder.CustomCommandProvider, and SessionCallbackBuilder.SkipCallback so may be a useful starting point for any required customizations.

        Specified by:
        getAllowedCommands in interface SessionCallbackBuilder.AllowedCommandProvider
        Parameters:
        session - The media session.
        controllerInfo - The MediaSession.ControllerInfo for the controller for which allowed commands are being queried.
        baseAllowedSessionCommands - Base allowed session commands for customization.
        Returns:
        The allowed commands for the controller.
