java - RTT time not being shown android studio using asyncTask -

- 

protected string doinbackground(pair<context,integer>... params){  // protected string doinbackground(pair<context, string>... params) {     context = params[0].first;     int name1 = params[0].second;     httpclient httpclient = new defaulthttpclient();      httppost httppost = new httppost("http://android- 996.appspot.com/hello"); // 10.0.2.2 localhost's ip address in android emulator     try {         string name= string.valueof(name1);         // add name data request         list<namevaluepair> namevaluepairs = new arraylist<namevaluepair>(1);         namevaluepairs.add(new basicnamevaluepair("name", name));         httppost.setentity(new urlencodedformentity(namevaluepairs));          // execute http post request         long starttime = system.currenttimemillis();         httpresponse response = httpclient.execute(httppost);         if (response.getstatusline().getstatuscode() == 200) {             return entityutils.tostring(response.getentity());         }         long elapsedtime = system.currenttimemillis() - starttime;         log.d("j", "total elapsed http request/response time in milliseconds" + elapsedtime);         system.out.println("total elapsed http request/response time in milliseconds: " + elapsedtime);          return "error: " + response.getstatusline().getstatuscode() + " " + response.getstatusline().getreasonphrase();      } catch (clientprotocolexception e) {         return e.getmessage();     } catch (ioexception e) {         return e.getmessage();     }} @override protected void onpostexecute(string result) {     toast.maketext(context, result, toast.length_long).show(); } }

i created app using android , @ backend using google app engine java servlet module. want calculate rtt time ,request transfer , response time . want display rtt time in logcat of android studio,but not getting output on logcat.

move below 3 lines above if block:

long elapsedtime = system.currenttimemillis() - starttime; log.d("j", "total elapsed http request/response time in milliseconds" + elapsedtime); system.out.println("total elapsed http request/response time in milliseconds: " + elapsedtime);

so becomes this:

long starttime = system.currenttimemillis();  httpresponse response = httpclient.execute(httppost);  long elapsedtime = system.currenttimemillis() - starttime;  log.d("j", "total elapsed http request/response time in milliseconds" + elapsedtime); system.out.println("total elapsed http request/response time in milliseconds: " + elapsedtime); if (response.getstatusline().getstatuscode() == 200) {     return entityutils.tostring(response.getentity()); }
