MyAddressBook

=============

This is the repository that contains both the starter and finished app for the

[Taking Advantage of Kotlin codelab](https://codelabs.developers.google.com/codelabs/taking-advantage-of-kotlin/#0). The starter app is written

in Java, which is then converted to Kotlin and extended.

MyAddressBook is an address book android application, that lists contacts

containing a first name, last name, and email address. The contacts can be

It contains validation for the input fields, stores the data in

SharedPreferences, and supports swipe to delete in the RecyclerView.
