You need to implement in client InBand Registration functionality

Answer 2

It's too late but hope it helps

           XMPPTCPConnectionConfiguration.Builder config = XMPPTCPConnectionConfiguration
                    .builder();
            config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
            config.setServiceName("nouman.test");
            config.setHost(serverAddress);
            config.setPort(5222);
            config.setDebuggerEnabled(true);
            XMPPTCPConnection.setUseStreamManagementResumptiodDefault(true);
            XMPPTCPConnection.setUseStreamManagementDefault(true);
            config.setSendPresence(true);
            config.setDebuggerEnabled(true);
            config.setSendPresence(true);
            config.setCompressionEnabled(false);
            connection = new XMPPTCPConnection(config.build());
            connection.connect();


 AccountManager accountManager = AccountManager.getInstance(connection);
        Map<String, String> attributes = new HashMap<>();
        attributes.put("name", "full_name");
        attributes.put("email", "email");
        try {
            if (accountManager.supportsAccountCreation()) {
                accountManager.sensitiveOperationOverInsecureConnection(true);
                accountManager.createAccount("username","password", attributes);
                isAccountCreated = true;
            }
        } catch (Exception e) {
            //TODO : Case 409 or Message conflict is the case of username exist handle the case
            LogUtil.printStackTrace(e);
        }

Make sure you have the correct service name otherwise you will get bad request error.

If you are using latest version then use this one.

new Thread() {
                    @Override
                    public void run() {
                        try {
                            AccountManager accountManager = AccountManager.getInstance(mConnection);
                            accountManager.sensitiveOperationOverInsecureConnection(true);
                            Map<String, String> map = new HashMap<String, String>();
                            map.put("username","vinay");
                            map.put("name", "vinay");
                            map.put("password", "vinay");
                            map.put("emial", "vinay@gmail.com");
                            accountManager.createAccount(Localpart.from("vinay"), "vinay", map);
                        } catch (SmackException.NoResponseException e) {
                            e.printStackTrace();
                        } catch (XMPPException.XMPPErrorException e) {
                            e.printStackTrace();
                        } catch (SmackException.NotConnectedException e) {
                            e.printStackTrace();
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        } catch (XmppStringprepException e) {
                            e.printStackTrace();
                        }

                    }
                }.start();

Answer 4

Just elaborating on what Flow has posted. AccountManager class has all the ingredients for maintaining user accounts in XMPP

Assume you have a connection object created.

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

Answer 5

Smack has InBand registration functionality that can be used via the AccountManager class. Note that not every server has this feature implemented/enabled.

Answer 6

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);
}
