android - HttpPost is not working in andorid (with php and iis 8) -
i use code data server hosted on internet using httppost request
and use asynctask class call makehttprequest method in jsonparser class in following link
public class jsonparser { static inputstream = null; static jsonobject jobj = null; static string json = ""; public jsonobject makehttprequest(string url, string method, list<namevaluepair> params) { try { if (method == "post") { defaulthttpclient httpclient = new defaulthttpclient(); httppost httppost = new httppost(url); urlencodedformentity urlencodedformentity = new urlencodedformentity( params); httppost.setentity(urlencodedformentity); httpresponse httpresponse = httpclient.execute(httppost); httpentity httpentity = httpresponse.getentity(); = httpentity.getcontent(); } else if (method == "get") { defaulthttpclient httpclient = new defaulthttpclient(); string paramstring = urlencodedutils.format(params, "utf-8"); log.d("get_param", paramstring); url += "?" + paramstring; log.d("get_url", url); httpget httpget = new httpget(url); httpresponse httpresponse = httpclient.execute(httpget); httpentity httpentity = httpresponse.getentity(); = httpentity.getcontent(); } } catch (unsupportedencodingexception e) { e.printstacktrace(); log.d("unsupportedencodingexception", "unsupportedencodingexception"); } catch (clientprotocolexception e) { e.printstacktrace(); log.d("clientprotocolexception", "clientprotocolexception"); } catch (illegalstateexception e) { // todo auto-generated catch block e.printstacktrace(); } catch (ioexception e) { // todo auto-generated catch block e.printstacktrace(); } try { bufferedreader reader = new bufferedreader(new inputstreamreader( is, "iso-8859-1"), 8); stringbuilder sb = new stringbuilder(); string line = null; while ((line = reader.readline()) != null) { sb.append(line + "\n"); } is.close(); json = sb.tostring(); log.d("json_string", json.tostring()); } catch (exception e) { log.e("buffer error", "error converting result " + e.tostring()); } try { jobj = new jsonobject(json); } catch (jsonexception e) { log.e("json parser", "error parsing data " + e.tostring()); } return jobj; } }

uses permission
<uses-permission android:name="android.permission.internet" /> i user php file
<?php $varusername = $_post['paramusername']; $varpassword = $_post['parampassword']; $success = array(); if($varusername == "anuja" && $varpassword == "123"){ $success['success'] = 'working'; echo json_encode($success); }else{ $success['success'] = 'invalid'; echo json_encode($success); } ?> it returning nothing.my emulator not responding @ time. when checked local wamp server worked when tried remote server not returning.
