I am trying to set up Google Cloud Messaging on Android with PHP (following this tutorial: http://www.androidhive.info/2012/10/android-push-notifications-using-google-cloud-messaging-gcm-php-and-mysql/). My device registers successfully with GCM and then with the server (the regId is stored into the database).
When I try and send to the device nothing is received, although I get this response:
{"multicast_id":4701392840778619841,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1355907831651938%978fee92f9fd7ecd"}]}
Google API reports that no requests have been made.
This is my send_notification function in PHP:
public function send_notification($registration_ids, $message) {
// include config
include_once './config.php';
// Set POST variables
$url = 'https://android.googleapis.com/gcm/send';
$fields = array(
'registration_ids' => $registration_ids,
'data' => $message,
);
$headers = array(
'Authorization: key=' . GOOGLE_API_KEY,
'Content-Type: application/json'
);
// Open connection
$ch = curl_init();
// Set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Disabling SSL Certificate support temporarly
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
// Execute post
$result = curl_exec($ch);
if ($result === FALSE) {
die('Curl failed: ' . curl_error($ch));
}
// Close connection
curl_close($ch);
echo $result;
}
From research, I have seen similar questions have been asked to this, however they vary slightly - for example, different programming languages and no solution that I have found has solved this problem.
Extra Info:
1. I have checked and cURL is enabled.
2. My onMessage method
protected void onMessage(Context context, Intent intent) {
Log.i(TAG, "Received message");
String message = intent.getExtras().getString("price");
displayMessage(context, message);
// notifies user
generateNotification(context, message);
}
(price in the above just retrieves the message as its stored like this: $message = array("price" => $message); before being given as a parameter to the send_notification function on the server.
I have checked LogCat and 'Received message' does not appear.
