Overview

This code snippet demonstrates how to add a specific contact to the contact list of the device.

The application creates a few input fields. After the user fills them in and presses the «Save» button, contact information with entered data will be added to the contact list, using the method ContactList.createContact().

If an error occurs, a message describing the error is displayed.
