Show (); } }); }The Wifip2pmanager.actionlistener interface in the code above is called only if the initialization succeeds or fails. If you want to listen to changes in the state of the connection, you need to implement the Wifip2pmanager.connectioninfolistener interface, and its method onconnectioninfoavailable () will be recalled when the connectio
