更新 :- 对于 smack 4.2.0-beta2 版本，使用以下代码配置 XmppConnection 以进行 PLAIN 身份验证。
XMPPTCPConnectionConfiguration.Builder builder = XMPPTCPConnectionConfiguration.builder();
builder.setHost("example.com");
builder.setPort(5222);
/*builder.setServiceName("example.com");*/ //for older version < 4.2.0-beta2
try
{
builder.setXmppDomain(JidCreate.domainBareFrom("example.com"));
}
catch (XmppStringprepException e)
{
e.printStackTrace();
}
/*builder.setServiceName("example.com");*/
builder.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
builder.setCompressionEnabled(true);
builder.setConnectTimeout(30000);
/*builder.setSendPresence(false);*/
