Lock.Android: Custom Fields at Signup
Lock.Android allows you to specify additional fields 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 the Custom Fields
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.
You can also create fields that will not be shown to the user but can be used to include additional metadata in a dynamic way after sign up.
// Regular field
val nameField = CustomField(R.drawable.ic_name, FieldType.TYPE_NAME, "first_name", R.string.hint_first_name, CustomField.Storage.PROFILE_ROOT)
// Hidden field
val androidField = HiddenField("android_version", Build.VERSION.SDK_INT.toString(), Storage.USER_METADATA)
val customFields = listOf(nameField, androidField)

Repeat the above steps as many times as fields you need.
Use the Custom Fields
Pass the list of custom fields to the Lock instance while you are building it, using the method withSignUpFields()
.
val lock = Lock.newBuilder(auth0, callback)
.withSignUpFields(customFields)
//...
.build(this)

If you have enabled sign up in the Application's Dashboard, users will be prompted to fill the remaining fields after they complete the basic fields (email/username, password) and hit Submit. The user must fill all of the custom fields before being able to complete the signup.
During sign up, the extra fields are attached to the user_metadata
attribute or are directly set in the root user profile, depending on the Storage option chosen. You can access these properties by querying the user profile at any time, even from the Dashboard in the User's section.
Field Types
Each custom field can only have one FieldType
associated.
TYPE_NAME
TYPE_NUMBER
TYPE_PHONE_NUMBER
TYPE_EMAIL
Storage
Each custom field can only have one Storage
associated. You can choose to store it at the root level in a root profile 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. By default, fields will be stored inside the user_metadata
attribute.
Available choices:
PROFILE_ROOT
USER_METADATA (default)
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.
