/**
 * Activity used to demonstrated safe partitioning of data.

 * <p>It has multiple partitions, but only accepts autofill on each partition at time.
 */
/*
 * TODO list
 *
 * - Fix top margin.
 * - Use a combo box to select if credit card expiration date is expressed as date or text.
 * - Use a dedicated TextView (instead of Toast) for error messages.
 * - Use wrap_context to CustomView container.
 * - Use different background color (or borders) for each partition.
 * - Add more partitions (like address) - should match same partitions from service.
 * - Add more hints (like w3c ones) - should match same hints from service.
