提前致谢
【问题讨论】：
【参考方案1】：希望这还不算太晚，错误是指 SASL 验证，我注意到您没有在 doInBackground() 中设置任何相关内容，请在您的 try 块中尝试以下操作（可能不完全是你需要，但这是基本的）：
ConnectionConfiguration config = new ConnectionConfiguration(server, port);
//... any other stuff you need
//very basic security stuff just to get you going...
config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
XMPPTCPConnection connection = new XMPPTCPConnection(config);
SASLAuthentication.supportSASLMechanism("DIGEST-MD5", 0);
connection.connect();
//... any other stuff you want
connection.login(user, passw);
希望这会有所帮助！
