java - Android 4.0.3 https post returns empty, http works, both works on 2.0.3 -

i'm connecting application rest type webservice. i'm using apache http library, request standard post request, ran in background thread.

now problem if i'm using

http://myserver.com/api/command 

it works , proper response, same url https:

https://myserver.com/api/command 

i empty response. http header 200 ok.

both of these work on 2.0.3 not on 4.0.3. on 4.0.3 api seems work if use plain http, https empty responses.

this code:

@override protected httpresponse doinbackground(string... params) {     string link = params[0];     httpclient client = createhttpclient();     try {         hashmap<string, contentbody> files = apimanager.getfiles();         multipartentity mpentity = new multipartentity();         if(files != null)  {             for(string : files.keyset()) {                 contentbody k = files.get(i);                 mpentity.addpart(i, k);             }         }         if(this.callparameters != null) {             for(namevaluepair : this.callparameters) {                 stringbody sb = new stringbody((string)i.getvalue(),"text/plain",charset.forname("utf-8"));                 mpentity.addpart(i.getname(), sb);             }         }         httppost.setentity(mpentity);         // execute http post request         log.d("apitask","executing request: "+httppost.getrequestline());         httpresponse response = null;         response = client.execute(httppost);         client.getconnectionmanager().shutdown();         return response;     }      catch(unknownhostexception e) {         exception = e;         return null;     }     catch (ioexception e) {         exception = e;         return null;     }     catch(exception e) {         return null;     } }  @override protected void onpostexecute(httpresponse result) {     system.out.println("status:"+result.getstatusline());     try {         stringbuilder responsetext = this.inputstreamtostring(result.getentity().getcontent());         system.out.println("response:"+responsetext);     }     catch(exception e) {         system.out.println("error");     } }  private httpclient createhttpclient() {     httpparams params = new basichttpparams();     httpprotocolparams.setversion(params, httpversion.http_1_1);     httpprotocolparams.setcontentcharset(params, http.default_content_charset);     httpprotocolparams.setuseexpectcontinue(params, true);     httpconnectionparams.setconnectiontimeout(params, 10000);     httpconnectionparams.setsotimeout(params, 10000);      schemeregistry schreg = new schemeregistry();     schreg.register(new scheme("http", plainsocketfactory.getsocketfactory(), 80));     schreg.register(new scheme("https", sslsocketfactory.getsocketfactory(), 443));     clientconnectionmanager conmgr = new threadsafeclientconnmanager(params, schreg);     return new defaulthttpclient(conmgr, params); } 

thank in advance
