Problem with receive push in some devices with '0123456789ABCDEF' serial number.

Messaging Service Push Notifications

I have a problem with some devices that have “0123456789ABCDEF” Serial Number. This is my code for register device:

Backendless.Messaging.registerDevice(GCMSenderId, channels, date, new AsyncCallback<Void>() {
    @Override
    public void handleResponse(Void arg0) {
        Log.i("GCM", "OK");
    }

    @Override
    public void handleFault(BackendlessFault arg0) {
        Log.i("GCM", "=" + arg0.getMessage());
    }
});

Registration work well but these device don’t receive push notifications. Although it’s work very well in other devices with real Serial Number.

Hi Reza. Push notifications work only on real devices. Not virtual

I know that, but they are real devices. Most of them have Android 4. I have 10,000 users and 500 of them have this problem. I had a research and find their serial number is the same, and it’s “0123456789ABCDEF”

In order to receive push notification, device serial should be unique.Try to set a unique value to Backendless.Messaging.DEVICE_ID before registering the device :

private static final String DEFAULT_SERIAL = "0123456789ABCDEF";

if (Backendless.Messaging.DEVICE_ID.equals(DEFAULT_SERIAL) {
  Backendless.Messaging.DEVICE_ID = UUID.randomUUID().toString();
}

Hope it helps
