library import about calimero-core HOT 3 CLOSED

The gradle version part does not start with a 'v', remove that.

Every connection implementation has a method to add a tuwien.auto.calimero.KNXListener, and every link implementation has a method to add a tuwien.auto.calimero.link.LinkListener. Both will provide you with a notification if the connection/link got closed.

Hello, thank you for your answer !

It's working, but I tested it deactivating mobile data and the linkClosed event is triggered after 30-45 seconds after turning mobile data off.. ain't 30 seconds too much?

        DataHolder.knxLink.addLinkListener(new NetworkLinkListener() {
            @Override
            public void confirmation(FrameEvent e) {
            }

            @Override
            public void indication(FrameEvent e) {
            }

            @Override
            public void linkClosed(CloseEvent e) {
                     //what to do on losing connection
            }
        });

The notification will be sent when the link actually got closed; if the link is idle and does not do any communication (and the socket is not closed by the OS), then there can be a certain time delay.

On Android, if you want an immediate notification about changes to your connection, you probably should use android.net.ConnectivityManager. CONNECTIVITY_ACTION or something like that.
