Maybe I am late, but if you are using latest smack-android:4.1.0, you can try below code for creating XMPPTCPConnectionConfiguration's connection object and register a user:

// Creating a connection
XMPPTCPConnectionConfiguration connConfig =
        XMPPTCPConnectionConfiguration.builder()
                .setHost("myHost.com")  // Name of your Host
                .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
                .setPort(5222)          // Your Port for accepting c2s connection
                .setDebuggerEnabled(true)
                .setServiceName("myServiceName")
                .build();
AbstractXMPPConnection connection = new XMPPTCPConnection(connConfig);

try {
    // connecting...
    connection.connect();
    Log.i("TAG", "Connected to " + connection.getHost());

    // Registering the user
    AccountManager accountManager = AccountManager.getInstance(connection);
    accountManager.sensitiveOperationOverInsecureConnection(true);
    accountManager.createAccount(username, password);   // Skipping optional fields like email, first name, last name, etc..
} catch (SmackException | IOException | XMPPException e) {
    Log.e("TAG", e.getMessage());
    xmppClient.setConnection(null);
}

If you have used smack 4.1.0 or above version convert your username to Localpart for create new account on server.

 public static void registration(String username,ICallBack iCallBack){

    AccountManager accountManager = AccountManager.getInstance(connection);
    try {
        if(accountManager.supportsAccountCreation()){
            accountManager.sensitiveOperationOverInsecureConnection(true);
            accountManager.createAccount(Localpart.from(username), username);
            iCallBack.onSuccess();
        }
    } catch (SmackException.NoResponseException | XMPPException.XMPPErrorException | SmackException.NotConnectedException e) {
        iCallBack.onFailure(e);
    } catch (InterruptedException e) {
        e.printStackTrace();
    } catch (XmppStringprepException e) {
        e.printStackTrace();
    }

}

I solved it by developing a webservice that takes the username and password as post parameters. If we post the username and pasword, the webservice registers a new user.

Instead of signing up from the app i found this to be rather simple...
