- callback

- Attributes
Remarks
Remove from the list a callback that was previously added with #register. This uses the IInterface#asBinder callback.asBinder() object to correctly find the previous registration. Registrations are not counted; a single unregister call will remove a callback after any number calls to #register for it.
