Lock.Android: Custom Fields at Signup

Lock.Android allows you to specify additional fields that the user must complete before creating a new account. The extra fields will be shown on a second screen after the user completes the basic fields (email, username, password).

Create a new CustomField object passing all these 4 mandatory parameters.

Icon: The int that points to the resource you want to use as Icon (keep it small).
Type: The FieldType to use in this field. The type defines the keyboard layout and sometimes the input validation.
Key: The String that identifies this value in the result JSON. It shouldn't be repeated! Repeated field keys will result in the second field getting removed from the list.
Hint: The @StringRes of the text to show as hint in the field.

In addition, you can specify where the field is going to be stored on the user's profile. See the Storage section below for details.

List<CustomFields> customFields = new ArrayList<>();

CustomField fieldName = new CustomField(R.drawable.ic_field_person, FieldType.TYPE_TEXT_NAME, "firstName", R.string.hint_first_name);
customFields.add(fieldName);

Repeat the above steps as many times as fields you need.

Create a new List to store the fields. Pass the list to the Lock.Builder before you build it, using the method withSignUpFields().

Lock lock = Lock.newBuilder(auth0, callback)
              .withSignUpFields(customFields)
              //...
              .build(this);

That's it! If you have enabled users Sign Up in the Application's Dashboard, after they complete the basic fields (email/username, password) and hit Submit, they will be prompted to fill the remaining fields. The user must fill all of the custom fields before being able to complete signup.

When requesting a user Sign Up or Sign In, the extra fields will be attached to the user_metadata attribute in the request body. You can access them by querying the user profile at any time, even from the Dashboard in the User's section.

Each custom field can only have one FieldType associated.

TYPE_NAME
TYPE_NUMBER
TYPE_PHONE_NUMBER
TYPE_EMAIL

Each custom field can only have one Storage associated. You can choose to store it right at the root level in a root attribute or inside the user_metadata attribute. To specify the storage location, use the five-parameter constructor and pass the Storage parameter of your choice (see below). By default, fields will be stored inside the user_metadata attribute.

Available choices:

PROFILE_ROOT
USER_METADATA (default)

CustomField fieldName = new CustomField(R.drawable.ic_field_person, FieldType.TYPE_TEXT_NAME, "firstName", R.string.hint_first_name, Storage.PROFILE_ROOT);

For the fields to be saved at the root level of the user's profile, their keys must match the ones listed in the endpoint documentation.
