xmppframework - How to manage XMPP connection -

i designing chat application using ejabberd xmpp server , smack 4.1 api. below code snippet managing connection.

    // create connection server.com server on 5222 port.     xmpptcpconnectionconfiguration config = xmpptcpconnectionconfiguration.builder()       .setusernameandpassword("user", "password")       .setservicename("server.com")       .sethost("server.com_ip")       .setport(5222)       .setsecuritymode(securitymode.disabled)       .build();     xmpptcpconnection conn = new xmpptcpconnection(config);     try {         conn.connect();         system.out.println("connection established.");         conn.login();         system.out.println("logged in.");     } catch (smackexception | ioexception | xmppexception e) {         system.out.println("connection not established: " + e.getmessage());     } 

some processing chat , muc.

    // disconnect     conn.disconnect();     system.out.println("connection closed."); 

my requirement:

• once user logs app, might not log out months @ time. way whatsapp works.

my question is:

• is idea keep connection open long user logged in?
• if not idea open , close connection every chat message?

need suggestion:

• what efficient way handle connection xmpp server?

although question different, this so answered might (comments too), in nutshell:

opening , closing connection each , every message not should do.

regarding keeping connection idle (like whatsapp), it's 1 of options (look services), other connect when application comes , stay connected long it's up, , use push notifications when app not running.

another option combination of both (more close whatapp does).

hope helps.
