php - How to send information from android app to server? -

hello everone started studying webservices in android , tried save information android app server

for firstly made php file. tried insert code using that. succesful in inserting code using php code file

<?php $con=mysqli_connect("localhost","root","","abhi_db"); // check connection if (mysqli_connect_errno()) {   echo "failed connect mysql: " . mysqli_connect_error(); }  // escape variables security $uname = mysqli_real_escape_string($con, $_post['uname']); $email = mysqli_real_escape_string($con, $_post['email']);  $sql="insert user_records (user_name, email) values ('$uname', '$email')";  if (!mysqli_query($con,$sql)) {   die('error: ' . mysqli_error($con)); } echo "1 record added";  mysqli_close($con); ?> 

after tried send information app server hitting url. code used is

public class mainactivity extends activity {       textview tv1;     httpclient httpclient;     httppost httppost;       @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);         tv1 = (textview) findviewbyid(r.id.tv1);         httpclient = new defaulthttpclient();         httppost = new httppost("http://10.0.2.2/name.php");         new getresult().execute();       }      @override     public boolean oncreateoptionsmenu(menu menu) {         // inflate menu; adds items action bar if present.         getmenuinflater().inflate(r.menu.main, menu);         return true;     }      public class getresult extends asynctask<void, void, void>{           string result = null;         @override         protected void doinbackground(void... arg0) {             // todo auto-generated method stub             try {                 list<namevaluepair> namevaluepairs = new arraylist<namevaluepair>(2);                 namevaluepairs.add(new basicnamevaluepair("uname", "rocky"));                 namevaluepairs.add(new basicnamevaluepair("email", "rockss"));                 httppost.setentity(new urlencodedformentity(namevaluepairs));               } catch (exception e) {                 // todo auto-generated catch block                 e.printstacktrace();                 log.e("exception", e.tostring());             }             return null;         }          @override         protected void onpostexecute(void result1) {             // todo auto-generated method stub             super.onpostexecute(result1);             tv1.settext("data inserted");             //log.i("my response :: ", result);         }      }  } 

in textview message i.e data inserted problem value not inserted in database.

so if people kindly tell mistake making. somuch helpful me. in advance

you need execute http post request:

        try {             httpparams params = new basichttpparams();             params.setparameter(coreprotocolpnames.protocol_version,             httpversion.http_1_1);             httpclient httpclient = new defaulthttpclient(params);              list<namevaluepair> namevaluepairs = new arraylist<namevaluepair>(2);             namevaluepairs.add(new basicnamevaluepair("uname", "rocky"));             namevaluepairs.add(new basicnamevaluepair("email", "rockss"));              httppost.setentity(new urlencodedformentity(namevaluepairs, "utf-8"));              string resp = httpclient.execute(httppost, new basicresponsehandler());         } catch (exception e) {             // todo auto-generated catch block             e.printstacktrace();             log.e("exception", e.tostring());         } 

to data server use below code:

        try {             httpparams params = new basichttpparams();             params.setparameter(coreprotocolpnames.protocol_version,             httpversion.http_1_1);             httpclient httpclient = new defaulthttpclient(params);              // put parameters if needed              string resp = httpclient.execute(httppost, new basicresponsehandler());              string[] nameemailpairs = resp.split("<br>");              for(string pair : nameemailpairs){                 string[] par = pair.split(" ");                 string name = par[0];                 string email = par[1];             }         } catch (exception e) {             // todo auto-generated catch block             e.printstacktrace();             log.e("exception", e.tostring());         }
