推荐答案

创建全局XMPPConnection对象，请使用以下功能可按并存储在全球XMPPConnection对象，并使用该连接对象无处不在。这是一个简单的，每增加一个例子。

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;
}
