Mentioned class and method createAccount
create new account on server as you can read from the Github code:
https://github.com/igniterealtime/Smack/blob/master/smack-extensions/src/main/java/org/jivesoftware/smackx/iqregister/AccountManager.java
Code:
/**
* Creates a new account using the specified username and password. The server may
* require a number of extra account attributes such as an email address and phone
* number. In that case, Smack will attempt to automatically set all required
* attributes with blank values, which may or may not be accepted by the server.
* Therefore, it's recommended to check the required account attributes and to let
* the end-user populate them with real values instead.
*
* @param username the username.
* @param password the password.
* @throws XMPPErrorException
* @throws NoResponseException
* @throws NotConnectedException
* @throws InterruptedException
