HTTPPOST with JSON Object having array -

below json object need pass on server:

{     "postimages": [{         "fileformat": "jpeg",         "id": "0",         "filebytearray": "long byte array of file",         "filecaption": "",         "videolink": ""     },{         "fileformat": "jpeg",         "id": "0",         "filebytearray": "long byte array of file",         "filecaption": "",         "videolink": ""     }],     "adminscheduleid": "0",     "categoryid": "1",     "userid": "4",     "presenter2": "0",     "ideatitle": "gfgfdgdfgdfg",     "isimplementedbyown": "false",     "noofvolunteer": "0",     "postid": "0",     "clubid": "2",     "description": " dfgdfgdf",     "presenter1": "0" } 

i have done passing json object server. create issue because of long byte array.

see below working code:

string res = null;      httppost request = new httppost(create_idea_url);     request.addheader("content-type", "application/json; charset=utf-8");     //request.addheader("content-type", "application/x-www-form-urlencoded");     try {          jsonarray array=new jsonarray(postimages); // array of images details          jsonobject jobject = new jsonobject()                     .put("ideatitle",ideatitle)                     .put("description",description)                     .put("isimplementedbyown",isimplementedbyown)                     .put("noofvolunteer",noofvolunteer)                     .put("postid",postid)                     .put("userid",userid)                     .put("clubid",clubid)                     .put("adminscheduleid",adminscheduleid)                     .put("categoryid",categoryid)                    .put("presenter1",presenter1)                    .put("presenter2",presenter2)                     .put("postimages",array);         stringentity entity = new stringentity(jobject.tostring(2),  "utf-8"); // add line have arabic language in post         system.out.println("jobject is:::: "+jobject.tostring());         request.setentity(entity);         system.out.println("====the entity is: "+entity.tostring());              defaulthttpclient httpclient = new defaulthttpclient();         //----------------------         if(lc5_api.getcookiesfromlc5() == null){         }else{          cookiestore cookiestore = new basiccookiestore();              for(cookie cook : lc5_api.getcookiesfromlc5()){                 cookiestore.addcookie(cook);              }             ((abstracthttpclient) httpclient).setcookiestore(cookiestore);         }             //-------------------         httpresponse response = httpclient.execute(request);         //res = response.tostring();         int rescode = response.getstatusline().getstatuscode();         system.out.println("our res: "+jobject.tostring());         system.out.println("result code: "+rescode);          bufferedreader in = new bufferedreader(new inputstreamreader(response.getentity().getcontent()));         string line="";         stringbuffer returnfromserver = new stringbuffer();         while ((line=in.readline())!=null){             returnfromserver.append(line);         }         //toast got server         //toast.maketext(getapplicationcontext(),returnfromserver.tostring(), toast.length_long).show();          system.out.println("responce: "+returnfromserver.tostring());         res = returnfromserver.tostring();          if (entity != null){             entity.consumecontent();         }         // toast.maketext(getapplicationcontext(),response.getstatusline().getstatuscode()+"", toast.length_long).show();     }catch(exception e){         e.printstacktrace();         res=null;     }      system.out.println("responcre is:"+res);     return res;*/  } public static string get_adoptidea(string postid) {     string responce = null;     restclient client = new restclient(get_adopt_idea);  //  if(lc5_api.debug) log.d("setcookie", lc5_api.session_cookiename + ":"+ lc5_api.session_cookievalue+""); //  client.addheader("cookie", session_cookiename+"="+lc5_api.session_cookievalue);      client.addparam("postid", postid);      try {         client.execute(requestmethod.get);         responce = client.getresponse();     } catch (connecttimeoutexception e) {         e.printstacktrace();         if(debug)log.d(tag, "");         responce=null;     }catch(exception e)     {         responce=null;     }      if(debug)log.d(tag, "response: "+responce);     return responce; 

above code works perfect. want send namevaluepair server.

see below code:

string res = null;     try {         httpclient client = new defaulthttpclient();           string url = create_idea_url;         httppost post = new httppost(url);          list<namevaluepair> postparameters;         postparameters = new arraylist<namevaluepair>();         //postparameters.add(new basicnamevaluepair("postid", postid));         postparameters.add(new basicnamevaluepair("ideatitle",ideatitle));         postparameters.add(new basicnamevaluepair("description",description));         postparameters.add(new basicnamevaluepair("isimplementedbyown",isimplementedbyown));         postparameters.add(new basicnamevaluepair("noofvolunteer",noofvolunteer));         postparameters.add(new basicnamevaluepair("postid",postid));         postparameters.add(new basicnamevaluepair("userid",userid));         postparameters.add(new basicnamevaluepair("clubid",clubid));         postparameters.add(new basicnamevaluepair("adminscheduleid",adminscheduleid));         postparameters.add(new basicnamevaluepair("categoryid",categoryid));         postparameters.add(new basicnamevaluepair("presenter1",presenter1));         postparameters.add(new basicnamevaluepair("presenter2",presenter2));           //postparameters.add(new basicnamevaluepair("postimages",ctx.getstring(r.string.json_object_test)));          jsonarray array = new jsonarray(postimages);          list<namevaluepair> param = new arraylist<namevaluepair>();            for(int i=0; i<array.length();i++){             imagesdata img = new imagesdata();               string video = array.getjsonobject(i).getstring("videolink").equalsignorecase("") ? "xyz" : array.getjsonobject(i).getstring("videolink");             system.out.println("video:: "+video);              param.add(new basicnamevaluepair("id", array.getjsonobject(i).getstring("id")));             param.add(new basicnamevaluepair("filecaption", array.getjsonobject(i).getstring("filecaption")));             param.add(new basicnamevaluepair("fileformat", array.getjsonobject(i).getstring("fileformat")));             param.add(new basicnamevaluepair("videolink", video));             param.add(new basicnamevaluepair("filebytearray", array.getjsonobject(i).getstring("filebytearray")));              postparameters.add(new basicnamevaluepair("postimages",param.tostring()));           }          post.setentity(new urlencodedformentity(postparameters));          post.setheader("content-type", "application/json; charset=utf-8");          if(lc5_api.debug) log.d("request rest:", "the requested string is:"+create_idea_url+postparameters);          //--------------------------------          if(lc5_api.getcookiesfromlc5() == null){          }else{             cookiestore cookiestore = new basiccookiestore();              //-------------------------------------------             for(cookie cook : lc5_api.getcookiesfromlc5()){                 cookiestore.addcookie(cook);              }             ((abstracthttpclient) client).setcookiestore(cookiestore);         }          //---------------------------------         httpresponse responsepost = client.execute(post);         httpentity resentitypost = responsepost.getentity();           if (resentitypost != null)          {             string response=entityutils.tostring(resentitypost);             res = response;         }     } catch (exception e) {e.printstacktrace();}     return res; 

now, when passes values above code gives me invalid json primitive: ideatitle.

everything fine not getting proper response. please me how pass json object having json array.

fyi, postimages json array details.

please me.
