Java and Android Development: A Beginner's Guide (2nd Edition)

This book is the Chinese translation of the English original Java for Android, 2nd Edition, written for readers who want to master the Java language and then engage in Android app development. The book has 50 chapters in total, divided into two major parts in learning order. Part One (Chapters 1 to 22) systematically explains the basics and core features of the Java language: starting from downloading and installing Java, the first program, coding conventions, and integrated development environments, it then introduces language basics, statements, objects and classes, core class libraries, arrays, inheritance, error handling, number operations, interfaces and abstract classes, polymorphism, enums, date and time handling, the collections framework, generics, input/output, annotations, nested and inner classes, threads, concurrency utilities, internationalization, and network programming. Part Two (Chapters 23 to 50) moves into practical Android platform development: first an overview of Android and setting up the development environment, then chapter by chapter covering activities, UI components, layouts, listeners, the action bar, menus, ListView, GridView, styles and themes, bitmap handling, graphics and custom views, fragments and multi-panel layouts, animation, preferences, file and database operations, taking photos and recording video, recording sound, Handler, asynchronous tools, services, broadcast receivers, alarm services, and content providers. The examples in the book are based on Java 8 and the official Android development environment of the time, and the appendices include descriptions of the three command-line tools javac, java, and jar, as well as brief introductions to NetBeans and Eclipse.
