RESTful web service error 500 on android

Question

Hello guys I'm new to restful service. My friend created REST backend with Spring. When I post this URL --> http://smartcar.tobaconsulting.com:9999/api/v1/login with postman or angularjs http.post, it's fine. You guys can check it out in postman by including this body

{ "username":"alvin", "password":"alvin" }

and set content type to JSON (application/json).

But when I code to Android, why it's not working and return 500 error code. My friend said that I'm not including header. I'm using loopj http library http://loopj.com/ . Here is my android code

        RequestParams params = new RequestParams();
        params.put("username", username);
        params.put("password", password);

        AsyncHttpClient client = new AsyncHttpClient();
        client.post("http://smartcar.tobaconsulting.com:9999/api/v1/login", params, new AsyncHttpResponseHandler() {
            @Override
            public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
                Log.d(TAG, String.format("status code: %d", statusCode));
            }

            @Override
            public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
                Log.d(TAG, String.format("status code: %d", statusCode));
            }
        });

Please help me guys. I trying to solve this problem for hours and haven't find any clue. Thanks

I would personally suggest using Volley lib for android, there is some useful method inside volley and google strongly recommended that Transmitting Network Data Using Volley
