http - Android login unauthorized -

i work on android project connect web service. there function show data after user login. login function call web service using http post method. here login code connect server:

public httpresponse makerequestnew(string path, string params, string params2) throws clientprotocolexception, ioexception      {      httpclient = new defaulthttpclient();      httppost httppost = new httppost(path);     httppost.setheader("content-type", "application/x-www-form-urlencoded;charset=utf-8");     list<namevaluepair> entity = new arraylist<namevaluepair>();     entity.add(new basicnamevaluepair("name", params));     entity.add(new basicnamevaluepair("pass", params2));       try {         httppost.setentity(new urlencodedformentity(entity));     } catch (unsupportedencodingexception e) {         // todo auto-generated catch block         e.printstacktrace();     }      // execute http post request     /*     try {         return httpclient.execute(httppost);     } catch (clientprotocolexception e) {         // todo auto-generated catch block         e.printstacktrace();         return null;     } catch (ioexception e) {         // todo auto-generated catch block         e.printstacktrace();         return null;     }     */     return httpclient.execute(httppost);  } 

i tried code , return http 200 code. it's mean code works , application connected server. when want show data, using code:

public jsonobject getjsonfromurlauth(string url) {      // making http request     try {         // defaulthttpclient         config c = new config();         jsonobject jo = c.getsetting();          defaulthttpclient httpclient = new defaulthttpclient();          //credentialsprovider credprovider = new basiccredentialsprovider();         try {             //credprovider.setcredentials(new authscope(authscope.any_host, authscope.any_port), new usernamepasswordcredentials(jo.getstring("username"), jo.getstring("password")));             //httpclient.setcredentialsprovider(credprovider);             httpclient.getcredentialsprovider().setcredentials(new authscope(authscope.any_host, authscope.any_port),                     new usernamepasswordcredentials(jo.getstring("username"), jo.getstring("password")));          } catch (jsonexception e1) {             // todo auto-generated catch block             e1.printstacktrace();         }           httppost httppost = new httppost(url);          httpresponse httpresponse = httpclient.execute(httppost);         httpentity httpentity = httpresponse.getentity();         = httpentity.getcontent();                 } catch (unsupportedencodingexception e) {         e.printstacktrace();     } catch (clientprotocolexception e) {         e.printstacktrace();     } catch (ioexception e) {         e.printstacktrace();     }      try {         bufferedreader reader = new bufferedreader(new inputstreamreader(                 is, "iso-8859-1"), 8);         stringbuilder sb = new stringbuilder();         string line = null;         while ((line = reader.readline()) != null) {             sb.append(line + "\n");         }         is.close();         json = sb.tostring();     } catch (exception e) {         log.e("buffer error", "error converting result " + e.tostring());     }      // try parse string json object     try {         jobj = new jsonobject(json);     } catch (jsonexception e) {         log.e("json parser", "error parsing data " + e.tostring());     }      // return json string     return jobj;  } 

it return http 401 unauthorized.
