尝试在ejabberd（17.07）的android设备上使用smack api（4.2）注册用户时出现错误

我试图找到错误的原因，但找不到。如果有人可以提出建议，将不胜感激。

I tried to find the reason of the error but cannot found it. If anyone can suggest a way it will be highly appreciated.

以前，我使用的是ejabberd 2.1版，默认设置为mnesia，可以正常工作。我可以从Android应用程序注册用户。

Earlier I was using ejabberd version 2.1 with default mnesia, which was working fine. I was able to register users from the android app.

但是现在当我用mysql安装新的ejabberd 17.07时，它给了我如下错误：

But now when I installed new ejabberd 17.07 with mysql, it gave me error as follow:
