In this part of my Android Development Tutorial I will continue talking about Fragments. If you missed parts 18 and 19 watch them first or you will be confused.

We will also cover how to use CheckBoxs and OnCheckChangedListener. Will explore how to generate unique IDs for all our contacts using UUID. Will create a singleton that will hold all our contacts in an ArrayList and more. All of the code is available below.
