我是XMPP的新手请指导我如何使用android在xmpp中发送和接收iq数据包。这是我的代码。当我调试我的代码时它会给我这个日志错误

这是我的代码
protected String doInBackground （String ... urls）
{
String host =web.vlivetech.com; //getText(R.id.host）;
String port =5222; //getText(R.id.port）;
String service =web.vlivetech.com; //getText(R.id.service）;
String username =has12345; //getText(R.id.userid）;
String password =123; //getText(R.id.password）;
//创建连接
ConnectionConfiguration connConfig =
new ConnectionConfiguration（host，Integer.parseInt（port），service）;
XMPPConnection connection = new XMPPConnection（connConfig）;
try {
connection.connect（）;
Log.i（XMPPClient，[SettingsDialog]已连接到+ connection.getHost（））;
} catch（XMPPException ex）{
Log.e（XMPPClient，[SettingsDialog]无法连接到+ connection.getHost（））;
MainActivity.setConnection（null）;
}
试试{
connection.login（用户名，密码）;
Log.i（XMPPClient，登录为+ connection.getUser（））;
//将状态设置为可用
Presence presence = new Presence（Presence.Type.available）;
connection.sendPacket（在场）;
MainActivity.setConnection（connection）;
} catch（XMPPException ex）{
Log.e（XMPPClient，[SettingsDialog]无法以+ username身份登录）;
MainActivity.setConnection（null）;
}
返回null;
}
I am new to XMPP please guide me how to send and receive iq packets in xmpp using android. Here is my code. when i debug my code it will give me this log error
