Hello, Android, 2/e : Introducing Google's Mobile Development Platform (Paperback)

Android is a software toolkit for mobile phones, created by Google and the Open Handset Alliance. It's inside millions of cell phones and other mobile devices, making Android a major platform for application developers. That could be your own program running on all those devices.

Getting started developing with Android is easy. You don't even need access to an Android phone, just a computer where you can install the Android SDK and the phone emulator that comes with it. Within minutes, "Hello, Android" will get you creating your first working application: Android's version of "Hello, World."

From there, you'll build up a more substantial example: an Android Sudoku game. By gradually adding features to the game throughout the course of the book, you'll learn about many aspects of Android programming including user interfaces,multimedia, and the Android life cycle.

This second edition has been completely revised for Android 1.5 (Cupcake) and Android 1.6 (Donut). Every page and example was reviewed and updated for compatibility with the new version. In addition, two new appendixes show you how to create Widgets for the Home screen and publish your application to the Android Market.

If you're a busy developer who'd rather be coding than reading about coding, this book is for you. To help you find what you need to know fast, each chapter ends with a "Fast-Forward" section. These sections provide guidance for where you should go next when you need to read the book out of order.

Android是由Google和Open Handset Alliance共同創建的用於移動電話的軟體工具包。它內置於數百萬部手機和其他移動設備中，使Android成為應用程式開發者的主要平台。你可以在所有這些設備上運行自己的程式。

開始使用Android開發非常簡單。你甚至不需要使用Android手機，只需要一台可以安裝Android SDK和附帶的手機模擬器的電腦。幾分鐘內，《Hello, Android》將帶你創建第一個可運行的應用程式：Android版本的“Hello, World”。

從那裡開始，你將逐步構建一個更完整的示例：一個Android數獨遊戲。通過在整本書的過程中逐步添加遊戲功能，你將學習Android編程的許多方面，包括用戶界面、多媒體和Android的生命週期。

這本第二版已完全修訂，適用於Android 1.5（Cupcake）和Android 1.6（Donut）。每一頁和示例都經過審查和更新，以與新版本兼容。此外，兩個新的附錄向你展示如何在主屏幕上創建小部件並將應用程式發佈到Android市場。

如果你是一個忙碌的開發者，寧願寫程式而不是閱讀有關程式的書籍，那麼這本書就是為你而寫的。為了幫助你快速找到所需的資訊，每一章結束時都有一個“快速前進”部分。這些部分提供了在需要按照順序閱讀書籍時應該接下來去哪裡的指導。
