By default, the HttpURLConnection class will not allow localhost as the hostname. You need to define a custom hostname verifier which will allow localhost. You can place this code into a static block at the top of the class where you intend to use HttpURLConnection:

public final class YourClassName {
    static {
        //for localhost testing only
        javax.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier(
            new javax.net.ssl.HostnameVerifier(){

                    public boolean verify(String hostname,
                                      javax.net.ssl.SSLSession sslSession) {
                        if (hostname.equals("localhost")) {
                            return true;
                        }
                        return false;
                    }
                });
    }

    // use HttpURLConnection here ...
}

Please find the working code,

PROXY_SERVER set to a valid proxy server and port for http I am using is 8080

proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(PROXY_SERVER, PROXY_PORT));

And when you establish the connection pass the proxy as an argument.

urlConnection = (HttpURLConnection) ((new URL(URI).openConnection(proxy)));
