How to send a high-priority GCM?

Question

I'm using a Nexus 5 with Android M Preview.

My problem that I'm trying to solve is:

Network access is disabled, unless your app receives a high priority Google Cloud Messaging tickle.

What I'm doing is:

I put the phone into Doze mode and then I send a push notification with the priority with value 10 and I'm expecting to have internet access for a brief moments, but this is not working.

Should I use other type of notifications? There are any documentation already available?

Thanks.

Answer 1

Setting priority to 10 is the correct thing to do, but it does not work with the version of Android M released at I/O. It has been fixed, and priority 10 messages will work as expected with the public release.

In fact, it's related with Google Play Services version not Android version. Use "high" for priority.

Just add this into your File (.php, .jsf, etc):

$fields = array(
                    'registration_ids' => $android,
                    **'priority' => 'high',**
                    'data' => array( 'message' => $message,
                                     'title' => $title,                                 
                                     'created_at' => $created_at,                                
                                     'is_background' => $is_background,
                                     'pantallaMostrarPushAndroid' => "pushNotificationNormal")
                ); 

                $ch = curl_init();
                curl_setopt($ch, CURLOPT_URL, $url);
                curl_setopt($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));

                // Execute post
                $resultAndroid = curl_exec($ch);
