Android : jquery signalr client works- but in java it cannot be made to work :-/

we have a SignalR hub. The following jquery code connects and properly processes SignalR client "call" events successfully on cordova.

        var connectionURL = urlName + "/message";
        connection = $.connection(connectionURL);

        connection.start().done(function () {
            console.log("Connected to hub again");
        });

        connection.disconnected(function () {
            setTimeout(function () {
                connection.start().done(function () {
                    console.log("Disconnected and Connected to hub again");
                });
            }, 5000);
        });

        connection.stateChanged(function (change) {
            if (change.newState == $.signalR.connectionState.reconnecting) {
            }
            else if (change.newState == $.signalR.connectionState.connected) {
            }
            else if (change.newState == $.signalR.connectionState.disconnected) {
            }// else if 
        });

        connection.received(function (data) {
            connectId = connection.id + "";
            console.log("onDeviceReady run");

            // call the function to parse the data
            if (data.PayloadType == "Dispatch") {
                dataDispatch(data);
            }
            if (data.PayloadType == "ConnectionAcknowledge") {
                sendConnectionAcknowledge(data);
            }
        });

however when I try to emulate this code in java apk android I get huge numbers of errors.

package com.some.thing;

public class SignalRHelper extends Service {

    @Override
    public void onCreate() {
        super.onCreate();
    }

    @SuppressWarnings("deprecation")
    @Override
    public void onStart(Intent intent, int startId) {
        super.onStart(intent, startId);
        Toast.makeText(this, "Service Start", Toast.LENGTH_LONG).show();

        String server = urlName + "/message";
        HubConnection connection = new HubConnection(server);
        HubProxy proxy = connection.createHubProxy("ptThroughputHub");

        SignalRFuture<Void> awaitConnection = connection.start();
        try {
            awaitConnection.get();
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (ExecutionException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        proxy.invoke("JoinGroup", "Group1");

        //Then call on() to handle the messages when they are received.
        proxy.on( "broadcastMessage", new SubscriptionHandler1<String>() {
            @Override
            public void run(String msg) {
                Log.d("result := ", msg);
            }
        }, String.class);   

    }
    @Override
    public void onDestroy() {
        super.onDestroy();
    }
    @Override
    public IBinder onBind(Intent arg0) {
        return null;
    }
}

can anyone help me translate the working, jquery signalr client code into usable java client code?
