java - Trying to connect to local data base with Httppost -

im trying user data date base hosted wamp. sent post request php file return json object app gets stuck in httpresponse response = cliente.execute(request);

this code:

private void obtenerjson() {     edittext nombre = (edittext) findviewbyid(r.id.txtnombre);     edittext password = (edittext) findviewbyid(r.id.txtpassword);      string nombreingresado = nombre.gettext().tostring().trim();     string passwordingresado = password.gettext().tostring().trim();      list<namevaluepair> datos = new arraylist<namevaluepair>();     datos.add(new basicnamevaluepair("nombre", nombreingresado));     datos.add(new basicnamevaluepair("password", passwordingresado));      httpclient cliente = new defaulthttpclient();     httppost request = new httppost("http://10.0.2.2/myfiles/myrequest.php");     bufferedreader lector =null;     stringbuffer stringbuffer = new stringbuffer("");      try {         request.setentity(new urlencodedformentity(datos));             httpresponse response = cliente.execute(request);             httpentity entidad = response.getentity();                                 if (entidad != null) {                 string resultado = entityutils.tostring(entidad, "utf-8");             }             lector = new bufferedreader(new inputstreamreader(response.getentity().getcontent()));             string linea = "";             string separadora = system.getproperty("line.separator");          while ((linea = lector.readline()) != null){              stringbuffer.append(linea + separadora);         }         lector.close();         interpretarjson(stringbuffer.tostring(), nombreingresado, passwordingresado);       } catch (exception e) {      } } 

the code below httpresponse response = cliente.execute(request); doesn't matter. thing when send request, return nothing. use log.d show response content, has nothing show.

this php code:

 <?php include('funciones.php');  $nombre = $_post["nombre"]; $password = $_post["pass"];  $result = getsqlresultset("select nombre, password   `usuario` nombre=".$nombre."");         while ($row = $result->fetch_array(mysqli_assoc)) {              foreach ($row $var => $comparar){                  if($nombre == $var ){                     $nombreok = true;                 }                 if($pass == $var){                     $passok = true;                 }                  if($nombreok && $passok){                     $devolver[] = $row;                 }             }                    }         echo json_encode($devolver); ?> 

this code funciones.php:

<?php function getsqlresultset($commando){ $mysqli = new mysqli("localhost", "root", "", "basededatos");  /* check connection */ if ($mysqli->connect_errno) {     printf("connect failed: %s\n", $mysqli->connect_error);     exit(); }   $var = $mysqli->execute($commando);      //return $mysqli->store_result();  $mysqli->close(); return $var; } ?> 

i think might using wrong ip, or problem in php code. translate code if necessary. thank you!
