The book requires basic knowledge of Java and system development in general, and the goal is that the reader, after reading this book, is able to write simple applications to an Android phone.
Important topics are the most common widgets, layouts and basically about activities, but also use of files and databases are processed. Mobile phone programming is in many ways different from programming to a usual computer, for example because the phone is another machine than a traditional computer, and the phone and, for that matter, other Android devices like tablets have other features that are not available on a PC. However, these features are dealt with in the following book.
As the title says this series of books deals with software development, and the goal is to teach the reader how to develop applications in Java. It can be learned by reading about the subject and by studying complete sample programs, but most importantly by yourself to do it and write your own programs from scratch. Therefore, an important part of the books is exercises and problems, where the reader has to write programs that correspond to the substance being treated in the books. All books in the series is built around the same skeleton and will consist of text and examples and exercises and problems that are placed in the text where they naturally belongs. The difference between exercises and problems is that the exercises largely deals with repetitions of the substance that is presented in the text, and furthermore it is relatively accurately described what to do. Problems are in turn more loosely described, and are typically a little bigger and there is rarely any clear best solution. These are books to be read from start to finish, but the many code examples, including exercises and problems plays a central role, and it is important that the reader predict in detail studying the code to the many examples and also solves the exercises and problems or possibly just studying the recommended solutions.
