Android is the fastest growing operating system (OS) with one of the largest installed bases of any mobile OS. Android uses one of the most popular programming languages, Java, as the primary language for building apps of all types. So, you should first obtain a solid grasp of the Java language and its foundation APIs to improve the chances of succeeding as an Android app developer.
This book will show you how to get your Android development environment set up and you will soon have your first working game. The difficulty level grows steadily with the introduction of key Java topics such as loops, methods, and OOP. You'll then use them in the development of games. You will learn how to build a math test game, a Simon-like memory game, a retro pong-style game, and for the grand finale, a Snake-style, retro arcade game with real Google Play leaderboards and achievements. The book has a hands-on approach and is packed with screenshots.

Learn how to use RxJava and its reactive Observables to build fast, concurrent, and powerful applications through detailed examples
If you are a Java developer that knows how to write software and would like to learn how to apply your existing skills to reactive programming, this book is for you.
Whether you are a Java expert or at a beginner level, you'll benefit from this book, because it will teach you a brand new way of coding and thinking.
The book starts with an explanation of what reactive programming is, why it is so appealing, and how we can integrate it in to Java. It continues by introducing the new Java 8 syntax features, such as lambdas and function references, and some functional programming basics. From this point on, the book focuses on RxJava in depth. It goes through creating Observables, transforming, filtering, and combining them, and concurrency and testing to finish with extending the library itself.
This book is a definite tutorial in RxJava filled with a lot of well-described examples. It explains reactive programming concepts in plain and readable language, without scientific formulas and terms.
Get thoroughly up to speed on Android programming, and learn how to create up-to-date user experiences for both handsets and tablets. With this book's extensively revised second edition, you'll focus on Android tools and programming essentials, including best practices for using Android 4 APIs. If you're experienced with Java or Objective-C, you'll gain the knowledge necessary for building well-engineered applications.
Programming Android is organized into four parts:
This updated edition of Programming Android focuses on the knowledge and developer priorities that are essential for successful Android development projects.
In todayâs app-driven era, when programs are asynchronous and responsiveness is so vital, reactive programming can help you write code thatâs more reliable, easier to scale, and better-performing. With this practical book, Java developers will first learn how to view problems in the reactive way, and then build programs that leverage the best features of this exciting new programming paradigm.
Authors Tomasz Nurkiewicz and Ben Christensen include concrete examples that use the RxJava library to solve real-world performance issues on Android devices as well as the server. Youâll learn how RxJava leverages parallelism and concurrency to help you solve todayâs problems. This book also provides a preview of the upcoming 2.0 release.
The book provides complete, accurate, and detailed coverage of the Java programming language. It fully describes the new features added in Java SE 8, including lambda expressions, method references, default methods, type annotations, and repeating annotations. The book also includes many explanatory notes and carefully distinguishes the formal rules of the language from the practical behavior of compilers.
