/**
* 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 {@link WifiAwareSession#createNetworkSpecifierOpen(int, byte[])} or
* {@link WifiAwareSession#createNetworkSpecifierPassphrase(int, byte[], String)}.
