I have what I thought would be quite a simple problem.
I'm trying to use JmDNS to broadcast a service which I've managed to do successfully, however when the app is paused, I want to unregister a service and then on resuming the app, reregister the service.
I am however running into issues doing this. The code is below:
//I use jmdns.create again before these lines which I don't know if i should?
mServiceInfo = ServiceInfo.create(registeredServiceName, registeredServiceType, registeredServicePort,"Hello");
try {
jmdnsNetworkDiscoveryManager.registerService(mServiceInfo);
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
Log.i(TAG, "Service Registration Error");
}
When I try this I get this error log which is confusing me:

Can someone explain to me what I'm doing wrong or an alternative approach. The strings I apply to the service creation are definitely valid as they are used to register a service earlier in the application.
