Insérer des coordonnées à mysql depuis android

Question

J'ai trouvé un tutoriel sur le service de localisation GPS. Tout fonctionne bien. La prochaine chose que je veux écrire est de passer des coordonnées de l'application à mysql. J'ai essayé plusieurs tutoriel sur mysql Android mais je ne sais pas comment les appliquer à ce code. Ce que j'essaye de réaliser est de onLocationChanged envoyer la latitude et la longitude à la base de données.

Quelqu'un pourrait-il me dire comment faire?

Voici le code:

connect.php

<?php 
define('HOST','localhost'); 
define('USER',''); 
define('PASS',''); 
define('DB','coordinates'); 

$con = mysqli_connect(HOST,USER,PASS,DB) or die('Unable to Connect'); 
?> 

insert.php

<?php 
require_once('connect.php'); 

if($_SERVER['REQUEST_METHOD']=='POST'){ 
    $la = $_POST['la_string']; 
    $lo = $_POST['lo_string']; 

    $get_result = $con->query("INSERT INTO gps(la,lo) VALUES ('$la','$lo')"); 

    if($get_result === true){ 
    echo "Successfully Registered"; 
    }else{ 
    echo "Not Registered"; 
    } 
}else{ 
    echo 'error'; 
}

Vous devez faire un appel via HttpClient à votre serveur et d'envoyer vos données par ce que vos données après codées.

try{ 
     String data = URLEncoder.encode("la_string", "UTF-8") + "=" + 
      URLEncoder.encode(data_la.text, "UTF-8"); 
     data += "&" + URLEncoder.encode("lo_string", "UTF-8") + "=" + 
      URLEncoder.encode(data_lo.text, "UTF-8"); 

     URL url = new URL(URL); 
     URLConnection conn = url.openConnection(); 

     conn.setDoOutput(true); 
     OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream()); 

     wr.write(data); 
     wr.flush(); 

     BufferedReader reader = new BufferedReader(new 
      InputStreamReader(conn.getInputStream())); 

     StringBuilder sb = new StringBuilder(); 
     String line = null; 

     // Read Server Response if you have something to do with it 
     while((line = reader.readLine()) != null) { 
      sb.append(line); 
      break; 
     } 

     return sb.toString(); 
    } catch(Exception e){ 
     return new String("Exception: " + e.getMessage()); 
    }
