public class IdentityChangedListener
extends Object


Base class for a listener which is called with the MAC address of the Aware interface whenever it is changed. Change may be due to device joining a cluster, starting a cluster, or discovery interface change (addresses are randomized at regular intervals). The implication is that peers you've been communicating with may no longer recognize you and you need to re-establish your identity - e.g. by starting a discovery session. This actual MAC address of the interface may also be useful if the application uses alternative (non-Aware) discovery but needs to set up a Aware connection. The provided Aware discovery interface MAC address can then be used in createNetworkSpecifierOpen(int, byte[]) or createNetworkSpecifierPassphrase(int, byte[], String).
