what may be the reasons for this issue. Please advice. Regards, Vinod

Answer 1

It was a mistake with me. the issue was with the variable name of the server script.

if (isset($_GET["regId"]) && isset($_GET["message"])) {
    $regId = $_GET["regId"];
    $message = $_GET["message"];

    include_once './GCM.php';

    $gcm = new GCM();

    $registatoin_ids = array($regId);
    $message = array("price" => $message);

    $result = $gcm->send_notification($registatoin_ids, $message);

    echo $result;
}     . The line $message = array("price" => $message); changed to   $message = array("message" => $message); Now I could get the push message on my android phone.
