Fügen Sie Koordinaten zu mysql von Android

Question

Ich habe ein Tutorial über GPS-Ortungsdienst gefunden. Alles funktioniert gut. Das nächste, was ich schreiben möchte, ist die Übergabe von Koordinaten aus der App an mysql. Ich habe mehrere Tutorials über Android mysql ausprobiert, aber ich weiß nicht, wie man sie auf diesen Code anwendet.

Was ich versuche zu erreichen, ist onLocationChanged senden Breite und Länge zu Datenbank.

Kann mir jemand sagen, wie das geht?

Dies ist der 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'; 
}

Sie haben einen Anruf über Httpclient zu Ihrem Server zu machen und Ihre Daten durch, dass als Beitrag senden mit Ihren Daten verschlüsselt.

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()); 
    }
