after a lot of research, I can´t find any clue about how to detect in real time if an user of my app is online ( running my app ). I know that most of this question its related to server side deployment, but I just can´t find nothing about this.
This is not too complicated to do with your own B4J server. You can use WebSockets or simply send a http request every minute or so. The server will track the connected clients and remove clients after a few minutes.
