Question

I’m making a chat with a notification service. Sometimes that the notifications dont arrives to my device. I’m using JavaPNS, so my code isn’t very complex, but when I send a lot of messages very quickly (about 10) from one device to another, I don’t receive all the notifications. Some of them are lost in the way (generally one of two).

Here is my code:

PushNotificationPayload payload = PushNotificationPayload.complex();
payload.addAlert("Name : text"); payload.addSound("default");
payload.addBadge(1); 
payload.addCustomDictionary("type", NOTIF_MESSAGE);
Push.payload(payload, "******.p12", "password", false, URI);

Answer 1

It’s OK.

Important: Because delivery is not guaranteed, you should not depend
on the remote-notifications facility for delivering critical data to
an application via the payload. And never include sensitive data in
the payload. You should use it only to notify the user that new data
is available.
