How to register a new user on XMPP using (a)Smack library

Question

I have set up a xmpp server and android client using the great post here... I have some pre defined users set up in the xmpp server and i could login with those credentials.

Answer 1

I want to update the answer to reflect the change in Asmack library version 4.0 onward. Connection.getAccountManager() is now AccountManager.getInstance(XMPPConnection)

AccountManager accountManager=AccountManager.getInstance(connection);
try {
    accountManager.createAccount("username", "password");
} catch (XMPPException e1) {
    Log.d(e1.getMessage(), e1);
}
