here is my PHP code

$response = array("error" => FALSE);

$username = 'mikielhyn';
$password = 'mikielhyn';
$email = 'mikielhynnipaya@yahoo.com';
if(userExist($email)){
$response["error"] = TRUE;
$response["error_msg"] = "User already existed with " . $email;
echo json_encode($response);
}else{
$use = storeUser($fullname,$address,$number,$username,$password,$email);
if ($use!=false) {
$user = getUserByEmail($email);
$response["error"] = FALSE;
$response["user"]["cid"] = $user["CustomerID"];
$response["user"]["fname"] = $user["fullname"];
$response["user"]["address"] = $user["address"];
$response["user"]["contact"] = $user["contact"];

echo json_encode($response);
}else {
// user failed to store
$response["error"] = TRUE;

echo json_encode($response);

}*/

if (isset($_POST['fullname']) && isset($_POST['useraddress']) && isset($_POST['number']) && isset($_POST['useremail']) && isset($_POST['password'])) {

It would really help if you could edit or repost your code using tags to preserve the formatting. Use [ code ] and [ /code ] - but without the spaces

I assume the error is happening here?

JSONObject jObj = new JSONObject(new String(response));
boolean error = jObj.getBoolean("error");

I'm curious why you're creating a new String instead of just using

JSONObject jObj = new JSONObject(response.toString());
