Quite late to answer for the thread but felt it will be helpful for someone. The same implementation works fine for FCM firebase implementation as well

// Get a random value 
int notificationId = new Random().nextInt();
// Add the notification ID which is unique as a first value of the notify method.
notificationManager.notify(notificationId, notificationBuilder.build());
