how to send google cloud messaging in queing?

Question

Hi i am sending notifications to android mobile from php server. Its working fine with single notifications. But if i send 2 notifications at once. First notification is replacing by second notifications. is there any way i can see 2 notifications in queing (ie like sms inbox message format).

Below is my php code:

<?php
define("GOOGLE_API_KEY", "API id");
define("GOOGLE_GCM_URL", "https://android.googleapis.com/gcm/send");

function send_gcm_notify($reg_id, $message) {

$fields = array(
    'registration_ids'  => array( $reg_id ),
    'data'              => array( "message" => $message ),
);

$headers = array(
    'Authorization: key=' . GOOGLE_API_KEY,
    'Content-Type: application/json'
);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, GOOGLE_GCM_URL);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));

$result = curl_exec($ch);
if ($result === FALSE) {
    die('Problem occurred: ' . curl_error($ch));
}

curl_close($ch);
echo $result;
}

$reg_id = "device id";
$msg = "Google Cloud Messaging working well";
 for($i=0;$i<=3;$i++){
 send_gcm_notify($reg_id, $msg);}

Answer 1

since you are sending data to the same notification builder.. second one is placed on top of first one. that is the default way of notification. but if you want to send multiple notifications for two tasks, you should use two notification builders and filter the received messages and call relevant notification builder. but there are limitations, so this depends on your program requirement.

Answer 2

if you are looking for notification as following image
