android - Keep getting "Target host must not be null, or set in parameters" -

i keep getting error above (title) when try make http-request server special character (the character 'å'). have tried call:

_login = urlencoder.encode(_login, "utf-8"); 

but still exception. if try change url works fine. seems happends whatever url try if has special characters. example http://www.ål.no.

anyone know work-around? 1 way of course use ip-address. rather avoid that.

thanks help!

some of source code:

    private string _login =        "http://www.ål.no";      httpclient httpclient = new defaulthttpclient();      try {         _login = urlencoder.encode(_login, "utf-8");     } catch (unsupportedencodingexception e1) {         // todo auto-generated catch block         e1.printstacktrace();     }      httppost httppost = new httppost(_login);      list<namevaluepair> namevaluepairs = new arraylist<namevaluepair>();      //namevaluepairs.add(new basicnamevaluepair("mail", this.email));     //namevaluepairs.add(new basicnamevaluepair("password", this.password));       try     {         httppost.setentity(new urlencodedformentity(namevaluepairs));          basichttpresponse response = null;          try         {             response = (basichttpresponse) httpclient.execute(httppost);         }         catch (clientprotocolexception e)         {             system.out.println("basichttpresponse");             e.printstacktrace();         } } 

edit: found work around. used firebug dig little deeper. according firebug server has name when communicating (as far can see). name not contain special characters , managed communicate server using application. help! :)
