Android/Firebase - Error while parsing timestamp in GCM event - Null timestamp

Question

I\'m building an Android app which will receive push notifications. I\'ve got Firebase Cloud Messaging setup and pretty much working, such that I can send the following payl

Answer 1

replace

 "notification" : {
    "title" : "title !",
    "body" : "body !",
    "sound" : "default"
  },
  "condition" : "'xxx' in topics",
  "priority" : "high",
  "data" : {
....

by (remove notification) :

{
  "condition" : "'xxxx' in topics",
  "priority" : "high",
  "data" : {
    "title" : "title ! ",
     "body" : "BODY",
 ......
}

And on you code : Replace :

 @Override
        public void onMessageReceived(RemoteMessage remoteMessage) { 
           remoteMessage.getNotification().getTitle();
           remoteMessage.getNotification().getBody();

        }

by

@Override
    public void onMessageReceived(RemoteMessage remoteMessage) { 
       remoteMessage.getData().get("title");
       remoteMessage.getData().get("body");

    }
