If you want help, you need to give more info.

Soory for late replying. My code is shown as below. The client can connect to the server with connect method, but it get "host-unknown" error at the login line

ConnectionConfiguration connConfig = new ConnectionConfiguration(
"192.168.0.44", Integer.parseInt(5222), "");

XMPPConnection conn
conn = new XMPPConnection(connConfig);

try{
conn.connect();

conn.login("test", "test");

}catch (Exception e){
}
