Class SessionCallbackBuilder.DefaultAllowedCommandProvider

java.lang.Object

com.castlabs.sdk.mediasession.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.

Method Details

acceptConnection

public boolean acceptConnection(androidx.media2.session.MediaSession session,
 androidx.media2.session.MediaSession.ControllerInfo controllerInfo)

Description copied from interface: SessionCallbackBuilder.AllowedCommandProvider

Called to query whether to allow connection from the controller.

If it returns true to accept connection, then SessionCallbackBuilder.AllowedCommandProvider.getAllowedCommands(androidx.media2.session.MediaSession, androidx.media2.session.MediaSession.ControllerInfo, androidx.media2.session.SessionCommandGroup) will be immediately followed to return initial allowed command.

Prefer use SessionCallbackBuilder.PostConnectCallback for any extra initialization about controller, where controller is connected and session can send commands to the controller.

Specified by:

acceptConnection in interface SessionCallbackBuilder.AllowedCommandProvider

Parameters:

session - The media session.

controllerInfo - The MediaSession.ControllerInfo for the controller that is requesting connect.

Returns:

true to accept connection. false otherwise.

getAllowedCommands

public androidx.media2.session.SessionCommandGroup getAllowedCommands(androidx.media2.session.MediaSession session,
 androidx.media2.session.MediaSession.ControllerInfo controllerInfo,
 androidx.media2.session.SessionCommandGroup baseAllowedSessionCommands)

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.

• MediaSession.SessionCallback.onConnect(MediaSession, ControllerInfo)

onCommandRequest

public int onCommandRequest(androidx.media2.session.MediaSession session,
 androidx.media2.session.MediaSession.ControllerInfo controllerInfo,
 androidx.media2.session.SessionCommand command)

Description copied from interface: SessionCallbackBuilder.AllowedCommandProvider

Called when a MediaController has called an API that controls SessionPlayer set to the MediaSession.

Specified by:

onCommandRequest in interface SessionCallbackBuilder.AllowedCommandProvider

Parameters:

session - The media session.

controllerInfo - A MediaSession.ControllerInfo that needs allowed command update.

command - A SessionCommand from the controller.

Returns:

A session result code defined in SessionResult.

• MediaSession.SessionCallback.onCommandRequest(androidx.media2.session.MediaSession, androidx.media2.session.MediaSession.ControllerInfo, androidx.media2.session.SessionCommand)

setTrustedPackageNames

public void setTrustedPackageNames(@Nullable
 List<String> packageNames)

Sets the package names from which the session will accept incoming connections.

Apps that have android.Manifest.permission.MEDIA_CONTENT_CONTROL, packages listed in enabled_notification_listeners and the current package are always trusted, even if they are not specified here.

Parameters:

packageNames - Package names from which the session will accept incoming connections.
