Additional Exercises

1. Try changing some of the questions and answers to the Android Quiz app. Doing so should not change any part of how the app functions—you are simply changing data.

2. Add questions and answers to the quiz. What do you have to change to make them appear?

3. Make the answers non–case sensitive so that cupcake and Cupcake will both be correct. You can do this without changing the question or answer text.

4. Add an image to go with each question, and have the picture on the screen change when the question changes.
