       List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
   while(keys.hasNext()){
    String key=keys.next();
    String value=keyAndValue.get(key);
       nameValuePairs.add(new BasicNameValuePair(key, value));
   }
       httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs,HTTP.UTF_8));
