    You should wrap your response inside a multidemnsional array in the way you are using it in the java code.

    Right now you have basicly set the signup part of the json array to the value of

    "Email Already Exist"

    which is not valid json to be decoded.

    This should do the trick: in the php part

    if (check_customer_email($con, $email)) {
    $msg["status"] = 0;
    $msg["msg"] = "Email Already Exist";
    $response["Signup"][] = $msg;
}
else {
    $sql = "insert into customer(cus_name, cust_email, cust_userpass,cus_mobile) values ('$name', '$email', '$userpass','$phone')";
if(mysqli_query($con, $sql)) {
    $msg["status"] = 1;
    $msg["msg"] = "Values successfully Added";
    $response["Signup"][] = $msg;
}
else {
    $msg["status"] = 0;
    $response["Signup"][] = $msg;
}

    The culprit in particular is this statement [and the ones like it in the code]

    array_push($response["Signup"], $msg["status"]);

    $msg['status'] will be a plain string where you would want to make this value an array by not just assingning it one key ["status"] from the array.
