i want insert php service. i've got error :

unable start service skripsi.ubm.studenttracking.altitudesurvey@366d624d intent { flg=0x4 cmp=skripsi.ubm.studenttracking/.altitudesurvey (has extras) }: android.os.networkonmainthreadexception 

this code :

public void insert() {         string time;         simpledateformat dayformat = new simpledateformat("hh:mm:ss", locale.us);         calendar calendars = calendar.getinstance();         time = dayformat.format(calendars.gettime());         try {             httpclient = new defaulthttpclient();             httppost = new httppost("http://studentstracking.hol.es/altitudesurvey.php");             namevaluepairs = new arraylist<namevaluepair>(2);             namevaluepairs.add(new basicnamevaluepair("baro", value));             namevaluepairs.add(new basicnamevaluepair("jam", time));             httppost.setentity(new urlencodedformentity(namevaluepairs));             response = httpclient.execute(httppost);             responsehandler<string> responsehandler = new basicresponsehandler();             final string response = httpclient.execute(httppost, responsehandler);             toast.maketext(altitudesurvey.this, "response server : " + response, toast.length_short).show();             if (response.equalsignorecase("success")) {                 toast.maketext(getapplicationcontext(), "data has been inserted", toast.length_short).show();             } else {                 toast.maketext(getapplicationcontext(), "data failed", toast.length_short).show();             }         } catch (clientprotocolexception e) {             e.printstacktrace();         } catch (unsupportedencodingexception e) {             e.printstacktrace();         } catch (ioexception e) {             e.printstacktrace();         }     } 

this method inside service. me how resolve ?

you facing android.os.networkonmainthreadexception means calling insert() method oncreate . need use asynctask save exception.

private class downloadfilestask extends asynctask<url, integer, long> {      protected long doinbackground(url... urls) {          insert()          return result;      }       protected void onprogressupdate(integer... progress) {       }       protected void onpostexecute(long result) {       }  } 

start asynctask

new downloadfilestask().execute();
