Question

I’am developing a sample push notification app in android using c2dm. Here is my PHP code to send the message from server to device.

function sendMessageToPhone($authCode, $deviceRegistrationId, $msgType, $messageText) {

    $headers = array('Authorization: GoogleLogin auth=' . $authCode);
    $data = array(
        'registration_id' => $deviceRegistrationId,
        'collapse_key' => $msgType,
        'data.message' => $messageText //TODO Add more params with just simple data instead           
    );

    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, "https://android.apis.google.com/c2dm/send");
    if ($headers)
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);


    $response = curl_exec($ch);

    curl_close($ch); 

}
sendMessageToPhone("my application server auth token ","my device id","UTF-8","hello");

But i’am getting “No info.” notification on my emulator. Where i’am going wrong ? Please help me.

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://android.apis.google.com/c2dm/send");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Authorization: GoogleLogin auth=$token", "Content-Length: $len", "Content-Type: application/x-www-form-urlencoded"));
echo curl_exec($ch);
curl_close($ch);

This is the php code that my app uses to send C2DM messages where $data is your data array. Please note that the Content-Length is necessary and is is the length of your data.

EDIT: Something you may also find useful a class for php that makes sending messages a little nicer.
