我使用了所有与 smack 相关的 api，以便我可以登录并在我的应用程序中使用 gtalk。所有的 api（smack 3.22、asmack、qsmack）都给了我同样的错误。错误是从 logcat 复制并粘贴在下面。请帮助我，我现在几乎很沮丧:(
XMPPConnection xmppConnection;
String host = "talk.google.com";
int port = 6222;
String service = "gmail.com";
String username = "test1";
String password = "password";
try {
xmppConnection = new XMPPConnection(new ConnectionConfiguration(host,
port, service));
xmppConnection.connect();
xmppConnection.login(username, password);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
服务器无响应：
