    @Override

} 

und dies ist der PHP-Code.

<?php 
require "time_init.php"; //connecting mysql 

$pic = $_POST["pic"]; 
$owner = $_POST["owner"]; 
$mobile = $_POST["mobile"]; 
$addrs = $_POST["addrs"]; 
$otime = $_POST["otime"]; 
$ctime = $_POST["ctime"]; 
$fee = $_POST["fee"]; 

$sql = "INSERT INTO park_info VALUES ('$pic', '$owner', '$mobile', '$addrs', '$otime', '$ctime', '$fee');"; 
mysqli_query($con, $sql) 

?>

denke ich, besser als aproach Anfrage Gebäude selbst Volley für den Umgang mit der Arbeit mit Anforderungen verwendet.

Volley ist eine HTTP-Bibliothek, die Netzwerke für Android-Apps einfacher und vor allem schneller macht.
