# Registering a user

User will be registered anonymously right after SDK initialization. To set specific user attributes, pass them using UserCom.getInstance().register() function. Usually, we are registering the client's information in LoginActivitiy when a client passes data in forms.

You should copy registerUserComCustomer() method e.g. for example to LoginActivity(if you want to get client's attribute in this activity) and then call it in method in which you want to retrieve client's information.

class LoginActivity{
    private void registerUserComCustomer() {

        Customer customer = new Customer()
                .id("idfromyourdatabase") // id of your user
                .attr("loyalCustomer", true)
                .attr("age", 33)

                .register(customer, new CustomerUpdateCallback() {
                    public void onSuccess(RegisterResponse response) {
                        Log.d(TAG, "onSuccess: " + response);
                        // user is registered and now you can send events via SDK

                    public void onFailure(Throwable throwable) {
                        Log.e(TAG, "onFailure: ", throwable);
                        // try again - something went wrong

This will create a user in User.com with all the attributes you specify, or log in an existing one if data matches the record in User.com database. You can add any number of custom customer attributes, or use predefined, and combine them.
