Android Async Http Client - Getting POST Url

Im using the LoopJ - Async Http Client For Android to perform some async post requests to login to a website. Im using the AsyncHttpRequestHandlers to keep the process async and seperate from the Android UI thread.

I want to get the page URL after the request - usually the HTTP Response is 200, with ocassional 3xx responses, in between the onSuccess method. Im unsure how I get access to the page URL.

Ive seen various solutions that use synchronous or deprecated methods

• Getting URL after a redirect using HttpClient.Execute(HttpGet) - Synchronous
• Obtaining URL from http response when no location header is sent - Synchronous
• Apache HttpClient: Location of redirected URLs - Deprecated
• HttpClient 4 - How to capture last redirect URL - Deprecated (Redirect Strategy)

Current Code Structure

static AsyncHttpClient client = new AsyncHttpClient();

static {
    client.setUserAgent(USER_AGENT);
    client.setEnableRedirects(true);
} 

public static void login(String user, String password) {
    RequestParams params = new RequestParams();
    params.put("login", user);
    params.put("password", password);

    client.post(LOGIN_URL, params, new TextHttpResponseHandler() {

        @Override
        public void onSuccess(int statusCode, Header[] headers, String responseString) {
            //Get Final Url Of Page
        }

        @Override
        public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {
            //Handle Failure
        }
    });
}

Is there a possible solution that I can easily integrate with this structure, whilst retrieving the current page url once the post request has been successful?
