I am using the XMPP Connection(using smack) for chat in android application.I have made the connection with openfire and also i can send and receive the message.But the problem is that when i go in the XMPPClient.java activity then it made the connection.So i cant get any message till not go in that activity.So how can made the connection at the starting and then reuse at other activity.Code is in this 2 links ConnectionSettings file and the chatscreen in which we can do chat.In this link the comment line is also my questions so please also see that comment.

Create global XMPPConnection object and Use below funciton and store in global XMPPConnection object and use that connection object everywhere. This is a sample gtalk example.

    public XMPPConnection login() throws XMPPException {

         ConnectionConfiguration config = new
         ConnectionConfiguration("talk.google.com",5222,"gmail.com");   
         config.setSecurityMode(SecurityMode.required);
         config.setTruststoreType("BKS");
         config.setTruststorePath("/system/etc/security/cacerts.bks");
         XMPPConnection connection = new XMPPConnection(config);        
        connection.connect();
        connection.login(username, password);
        Presence presence = new Presence(Presence.Type.available);
        presence.setMode(Presence.Mode.available);  
        connection.sendPacket(presence);
        try {
            Thread.sleep(3000);
        } catch (Exception ex) {
            ex.printStackTrace();
        }
     return connection;
}
