4. Going for Your First Ride: Creating an Android User Interface
Life is like a riding a bicycle, you don’t fall off unless you stop pedaling.

By creating this application, you will learn more about how to code with the Android activity lifecycle, how to code a simple user interface, and how to specify user preferences.
