   @Override
    public void onCreate() {
        super.onCreate();
//how to get notification body here not in onMessageReceived(RemoteMessage remoteMessage) 
    }
}

Answer 1

Messages are handled in onMessageReceived() , see the example at the bottom.

Firebase has multiple message types - notification messages and data messages: https://firebase.google.com/docs/cloud-messaging/concept-options#notifications_and_data_messages

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);

    //notification message
    RemoteMessage.Notification notification = remoteMessage.getNotification();
    String body = notification.getBody();

    //data message
    Map<String, String> data = remoteMessage.getData();
}
