это мой код, он отлично работает для меня, я надеюсь, что он будет полезен для вас. Спасибо

попробуй это

private final static String server_host = "talk.google.com";
private final static int SERVER_PORT = 5222;
private final static String SERVICE_NAME = "gmail.com";

ConnectionConfiguration config = new ConnectionConfiguration( server_host, SERVER_PORT , SERVICE_NAME);
        XMPPConnection m_connection = new XMPPConnection(config);
                try {
                     SASLAuthentication.supportSASLMechanism("PLAIN");
                     config.setSASLAuthenticationEnabled(true);     
                     m_connection.connect();
                    Roster.setDefaultSubscriptionMode(Roster.SubscriptionMode.manual);
                } catch (XMPPException e) {
                    e.printStackTrace();
                }       

Я нашел решение этой проблемы. Это было связано с обновлением, которое я сделал для API. Я удалил импортированную библиотеку ASmack из свойства своего проекта. Папка Lib тоже отсутствовала. Поэтому я создал одну папку («libs») в проекте и вставил туда банку ASmack. Очистив проект один раз, ошибка была исправлена. Спасибо. Справочник
