Implement this interface to receive control over various channel events. Channels will try to get this interface from a channel's notificationCallbacks or, if not available there, from the loadGroup's notificationCallbacks. These methods are called before onStartRequest, and should be handled SYNCHRONOUSLY.

code.
@param oldChannel

@param newChannel
