Android - SignalR - not receiving message from server

[vandanabpatel]

HubConnection mHubConnection; HubProxy mHubProxy;

try { Platform.loadPlatformComponent(new AndroidPlatformComponent()); mHubConnection = new HubConnection("http://differenzuat.com/SignalRChat/signalr/hubs"); mHubProxy = mHubConnection.createHubProxy("ChatHub"); ClientTransport transport = new ServerSentEventsTransport(mHubConnection.getLogger());

        mHubProxy.on("sendPrivateMessage",
                new SubscriptionHandler1<Object>() {
                    @Override
                    public void run(final Object result) {
                        Log.e(TAG, "Message Received :: ");
                        try {
                            JSONObject json = decodeResult(result);
                            Log.e(TAG, "Message Received :: " + json.toString());
                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                    }
                }, Object.class);

        SignalRFuture<Void> signalRFuture = mHubConnection.start();
        signalRFuture.get();

        mHubConnection.error(new ErrorCallback() {
            @Override
            public void onError(Throwable e) {
                Log.e(TAG, "mHubConnection.error :: " + e.toString());
                e.printStackTrace();
            }
        });

        // Subscribe to the connected event
        mHubConnection.connected(new Runnable() {
            @Override
            public void run() {
                Log.e(TAG, "CONNECTED");
            }
        });

    } catch (InterruptedException e) {
        e.printStackTrace();
    } catch (ExecutionException e) {
        e.printStackTrace();
    }

// here, i am calling invoke method to send message mHubProxy.invoke("SendPrivateMessage", "30", "31", "test message", "");

public static JSONObject decodeResult(Object result) throws JSONException { if (result == null) return null; Gson gson = new GsonBuilder().serializeNulls().create();//Fix the missing null attributes problem return new JSONObject(gson.toJson(result)); }

============================== i am getting following error log

I believe the exception says that your callback has just one parameter but the server is trying to invoke it with 7 arguments so there is a mismatch.
