This tutorial shows how to use basic overflow menus, which expand from the top right part of the action bar, to change the color of the action bar. The tutorial is also made using material design themes and colors, according to the new design guidelines.
It is of course possible to use material design with pre-lollipop versions of android by using the support libraries, however, for this first video, I like to keep things simple and stick to just lollipop.
If you are interested in the source code I will be more than happy to create a Github repository.
Thanks for watching, and feel free to ask for any topics you want to learn about :)
