 public void registeruser(hashmap<string,string> map)     {           uri.builder builder = uri.parse(baseuri).buildupon();         builder.appendpath("api.php");         for(map.entry<string, string> entry:map.entryset())         {         builder.appendqueryparameter(entry.getkey(),entry.getvalue());         }         uri builturi = builder.build();         log.i("hossam", builturi.tostring());         httpclient httpclient = new defaulthttpclient();           httpget request = new httpget(builder.tostring());            responsehandler<string> handler = new basicresponsehandler();           string result = null;         try {               result = httpclient.execute(request, handler);           } catch (clientprotocolexception e) {               e.printstacktrace();           } catch (ioexception e) {               e.printstacktrace();           }           httpclient.getconnectionmanager().shutdown();           string tag = null;         //log.i("http response", result);       } 

the order issue, because using map, , in java maps unordered , unsorted type of collection, unless use either linkedhashmap or treemap cost way more in performance regular list, if want specific order must go list, other way map return values in unordered way, , related special characters because url contains them, , default url coneverted encoded version of them since can ascii, here list of url encoded characters... http://www.degraeve.com/reference/urlencoding.php
