            HttpPost httppost = new HttpPost(builder.getUrl());
            httppost.setHeader(HTTP.CONTENT_TYPE,
                    "application/x-www-form-urlencoded;charset=UTF-8");
            // Add your data
            httppost.setEntity(new UrlEncodedFormEntity(builder
                    .getNameValuePairs(), "UTF-8"));

            // Execute HTTP Post Request
            HttpResponse response = httpclient.execute(httppost);

Note: the builder just contains url and namevalue pairs.
