Overview of this book

Android is one of the most popular mobile operating systems presently. It uses the most popular programming language, Java, as the primary language for building apps of all types. However, this book is unlike other Android books in that it doesn’t assume that you already have Java proficiency. This new and expanded second edition of Learning Java by Building Android Games shows you how to start building Android games from scratch. The difficulty level will grow steadily as you explore key Java topics, such as variables, loops, methods, object oriented programming, and design patterns, including code and examples that are written for Java 9 and Android P. At each stage, you will put what you’ve learned into practice by developing a game. You will build games such as Minesweeper, Retro Pong, Bullet Hell, and Classic Snake and Scrolling Shooter games. In the later chapters, you will create a time-trial, open-world platform game. By the end of the book, you will not only have grasped Java and Android but will also have developed six cool games for the Android platform.

Using Java packages

Packages are grouped collections of classes. If you look at the top of the code that we have written so far, you will see these lines of code.

import android.app.Activity;
import android.os.Bundle;

These lines of code make available the Activity and Bundle classes as well as their methods. Comment out the above two lines like this:

// import android.app.Activity;
// import android.os.Bundle;

Now look at your code and you will see errors in at least three places. The word Activity has an error because Activity is a class which Android Studio no longer is aware of in the following line:

public class SubHunter extends Activity {

The word onCreate also has an error because it is a method from the Activity class and the word Bundle has an error because it is a class which since we commented out the previous two lines Android is no longer aware of. This next line highlights where the errors are.

protected void onCreate(Bundle savedInstanceState) {

Uncomment the two lines of code...
