Android Development 20

Android Development 20In 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.

  1. Hi Derek,

    won’t you store all of the contacts into database? Just the way you did it in ContactApp.

    Thanks

  2. Derek, thanks for the solid effort in all video tutorial.
    I have learned a great deal of android programming.
    Would you be discussing on any interface controls like eye gazing ?
    Would be interested in location sensing application too.
    once again thanks for your great work!

    1. Hi Gary, Thank you I’m very happy that you’re enjoying them. I have no idea where this tutorial will go and it is possible I could go down the road of covering location sensing, but I have never done that stuff. Thank you for the request 🙂
