Pass a return value from a method,which is a json array, to android asynctask, doInBackground method as an argument -

the json array passed doinbackground return value of following method.

   public jsonarray json_encode(){        string[] log_data;       log_data= this.credentials();       jsonobject  json_var=new jsonobject();         try{         json_var.put("username" ,log_data[0] );         json_var.put("password" ,log_data[1] );          }         catch(jsonexception e){           e.printstacktrace();            }      jsonarray json_array=new jsonarray();     json_array.put(json_var);        return json_array;   } 

i need pass return json array doinbackground method argument. how it? both methods in different class , method's return value passed (json array) in first class (main_activity),the second class aysnctask class ( class background_thread extends asynctask ) , need pass return array doinbackground method of second class.

well, if want value in doinbackground() :-

public class youractivity extends activity {   ...    jsonarray mjsonarray;   ...     @override     protected void oncreate(bundle savedinstancestate) {     ...      mjsonarray = json_encode();      new yourasynctask().execute();     }         private class yourasynctask extends asynctask<void,void,void>{          @override         protected void doinbackground(void... params) {            //now can use mjsonarray here inner class             return null;        }      }  }
