我使用的是smack4.1.2，引用方法我之前在ejabberd的连接、登录、收发消息这部分介绍过了

在使用注册功能之前，也需要对ejabberd服务器的配置进行一些小的修改，或者使用创建功能却遇到了403 -auth错误的朋友也可以参考一下。具体方法如下:

完成了上述的准备工作后，我们就可以进行ejabberd用户的创建了。具体方法如下:
private void XmppRegister(String username){
AccountManager account = AccountManager.getInstance(con);
account.sensitiveOperationOverInsecureConnection(true);
try {
boolean tag = account.supportsAccountCreation();
if(tag){
Log.d("PushTest", "you can register");
}
account.createAccount(username, "123456");
Log.d("PushTest", "register successfully");
} catch (SmackException.NoResponseException e) {
e.printStackTrace();
} catch (XMPPException.XMPPErrorException e) {
e.printStackTrace();
} catch (SmackException.NotConnectedException e) {
e.printStackTrace();
}
}

需要注意的是:
1、需要先建立连接，再进行创建用户
2、连接的账号需要具备创建用户的权限
如果有什么问题，欢迎大家不吝指教!
