And, according to material design guidelines, user interactions should be illustrated graphically using movement and color to intuitively demonstrate the action being performed, such as the ripple animations that result from tapping on a button.

But first, we will examine one or two more ways of applying the look and feel we want, and Android users expect, to our designs. This process is largely assisted by the use of support libraries, in particular, the AppCompat...
