Android NSD. Have errors when trying to resolve

Question

I'm making android quiz with local network multiplayer where host should send message to all clients. I'm using this sample of NsdChat. But when I try to reslove service I get this errors.

E/NsdServiceInfo: While parsing txt records (pos = 1): Zero sized txt record
E/NsdHelper: Resolve Succeeded. name: NsdChatHost, type: ._http._tcp, host: /"myIP", port: "myPort", txtRecord: 
E/NsdService: Unique id with no client mapping: 71
E/NsdService: Unhandled { when=-4ms what=393242 obj=com.android.server.NsdService$NativeEvent@157683e target=com.android.internal.util.StateMachine$SmHandler }

It's my resolve listener.

public void initializeResolveListener() {
        mResolveListener = new NsdManager.ResolveListener() {
            @Override
            public void onResolveFailed(NsdServiceInfo serviceInfo, int errorCode) {
                Log.e(TAG, "Resolve failed" + errorCode);
            }
            @Override
            public void onServiceResolved(NsdServiceInfo serviceInfo) {
                Log.e(TAG, "Resolve Succeeded. " + serviceInfo);
                if (serviceInfo.getServiceName().equals(mServiceName)) {
                    Log.d(TAG, "Same IP.");
                    return;
                }
                mService = serviceInfo;
            }
        };
    }
