AttachCallback
open class AttachCallback
Base class for Aware attach callbacks. Should be extended by applications and set when calling WifiAwareManager.attach(AttachCallback, android.os.Handler). These are callbacks applying to the Aware connection as a whole - not to specific publish or subscribe sessions - for that see DiscoverySessionCallback.
