Challenges

Challenges are exercises at the end of the chapter for you to do on your own. Some are easy and provide practice doing the same thing you have done in the chapter. Other challenges are harder and require more problem solving.

We cannot encourage you enough to take on these challenges. Tackling them cements what you have learned, builds confidence in your skills, and bridges the gap between us teaching you Android programming and you being able to do Android programming on your own.

If you get stuck while working on a challenge, take a break and come back to try again fresh. If that does not help, check out the forum for this book at forums.bignerdranch.com. In the forum, you can review questions and solutions that other readers have posted as well as ask questions and post solutions of your own.

To protect the integrity of your current project, we recommend you make a copy and work on challenges in the new copy.

In your computer’s file explorer, navigate to the root directory of your project. Copy the GeoQuiz folder and Paste a new copy next to the original (on macOS, use the Duplicate feature). Rename the new folder GeoQuiz Challenge. Back in Android Studio, select FileImport Project.... Inside the import window, navigate to GeoQuiz Challenge and select OK. The copied project will then appear in a new window ready for work.
