我正在使用asmack 4.0.7和eclipse。
这是我用来连接服务器的代码：
config = new ConnectionConfiguration("192.168.43.214", 5223);
// config.setReconnectionAllowed(true);
config.setDebuggerEnabled(true);
config.setSecurityMode(SecurityMode.disabled);
connection = new XMPPTCPConnection(config);
connection.setPacketReplyTimeout(10000L);
connection.connect();
connection.login(session.getUsername(), session.getRamz());
和logcat：

有什么问题？
答案 0 :(得分：0)
很奇怪，但我在OnDestroy中有这行代码，经过大量的跟踪和调试后，我发现它导致了这个问题：
if (run != null)
run.cancel(true);
* run是应用程序用来连接服务器的AsyncTask。
我注释掉了2行，app现在连接到服务器没有任何问题。
