Android HttpURLConnection seems to post nothing? -

any idea why not posting data? php page $_post array(0){} or in other words nothing in $_post. getdata() string full of data. i'm trying switch deprecated defaulthttpclient.

httpurlconnection conn = null;             try {                 url u = new url(url);                 conn = (httpurlconnection) u.openconnection();                 conn.setdooutput(true);                 conn.setdoinput(true);                 conn.setchunkedstreamingmode(0);                 conn.setconnecttimeout(10000);                 conn.setreadtimeout(10000);                 conn.setrequestmethod("post");                 conn.setrequestproperty("content-type", "application/x-www-form-urlencoded");                 //conn.setrequestproperty("content-type","application/json");                 conn.getoutputstream().write(getdata().getbytes("utf-8"));                 conn.connect();                  inputstream content = new bufferedinputstream(conn.getinputstream());                 bufferedreader buffer = new bufferedreader(new inputstreamreader(content));                 string s = "";                 while ((s = buffer.readline()) != null) {                     builder.append(s + "\n");                 }             } catch (exception e) {                 e.printstacktrace();             } {                 conn.disconnect();             } 

the best approach -->>

class jsonasynctask extends asynctask<string, void, boolean> {   protected void onpreexecute() {     super.onpreexecute();     dialogoff.setmessage("loading data..");  } protected boolean doinbackground(string... urls) {       try {          httpget httppost = new httpget(urls[0]);         httpclient httpclient = new defaulthttpclient();         httpresponse response = httpclient.execute(httppost);          // statusline stat = response.getstatusline();         int status = response.getstatusline().getstatuscode();          if (status == 200) {             httpentity entity = response.getentity();             string data = entityutils.tostring(entity);              data=new string(data.getbytes("iso-8859-1"), "utf-8");              jsonarray jarray = new jsonarray(data);             latlng point;              (int = 0; < jarray.length(); i++)                  jsonobject object = jarray.getjsonobject(i);                 return true;         }        } catch (ioexception e) {         e.printstacktrace();     } catch (jsonexception e) {         e.printstacktrace();     }        return false; } protected void onpostexecute(boolean result) {       if(result)        toast.maketext(getapplicationcontext(), "data transfered successfully", toast.length_long).show();     else{         toast.maketext(getapplicationcontext(), "unable fetch server", toast.length_long).show();         dialogoff.cancel();     }    }
