具体描述

Ask yourself...how do you learn best? Well, like most programmers, you may well prefer to have a solid, real app that you can tear apart and analyze bit by bit. Featured on phones like the Google Nexus One, the Motorola Droid, the Samsung Galaxy S, a variety of HTC phones, and the many Android-based tablet computers, Android is a powerful, full-featured, open source mobile platform that is ready for discovery, use, and creative programming.

This Android Projects book provides you first with a brief and concise introduction to the Android platform. It then dives right into setting up the Android SDK. Starting from scratch, you will learn how to set up the tools and configure Eclipse and Netbeans with their appropriate Android plug-ins on top of the Android SDK. From there you will be building and extending fun and creative mobile applications using the Android SDK, Java, and other languages such as Python, Ruby, Javascript/HTML, Flex/AIR, and Lua.

What you’ll learn The quickest way to get a working Android virtual device up and running your code Key Android platform architecture concepts and application principles Build, debug, and sign your Java Android apps with the SDK tools, Eclipse, and Netbeans Code for an open, accessible, component-based, mobile, and powerful computing platform Code Android applications with open web development technologies for maximum cross-platform compatibility Code Android applications with Python, Ruby, Javascript/HTML, and Flex Extend Android Java application code with free and open source scripting languages Develop Android applications that interact with social web applications Get up and running with Android graphics and game development Who this book is for Any developer new to the Android platform who wants to learn to build mobile applications using the Android SDK, Java, and other languages such as Python, Ruby, Javascript/HTML, Flex, and Lua. Knowledge of the fundamentals of Java programming is assumed. Table of Contents Introducing Android Roll your own Android scripting environment Hosting open source JVM extension scripting languages on Android Beginning Android scripting with Scripting Layer for Android (SL4A) How to interact with a third party web API using REST Beginning Android development with Rhodes and Ruby Programming an Android GUI: Javascript/HTML and Flex with AIR Practical Approach: Android and Google App Engine Android and Social Media: Facebook and Twitter Game Development: Graphics Game Development: Animations App Inventor Setup and Sample Project

用户评价

作为一名工作了几年、自认为对移动开发有所了解的工程师，我发现这本书仍然能带给我很多“原来如此”的时刻。它的深度和广度达到了一个很好的平衡点。很多初级书籍会教你如何使用现成的库，而高级书籍又可能过于聚焦于底层源码，让人感觉脱离实际。这本书恰恰填补了这个空白。它不仅展示了如何有效集成那些流行的第三方库，更重要的是，它教会了你如何在关键时刻“放弃”依赖外部库，转而自己动手实现那些性能敏感的核心功能。例如，书中关于后台任务调度的章节，详细对比了JobScheduler、WorkManager以及原生的AlarmManager的适用场景和性能损耗，并且给出了一个基于项目需求的决策树。这种不偏不倚、注重实效的分析，让我对Android系统的调度机制有了更深刻的敬畏和理解。它不是在推销某种“最佳实践”，而是在教授你如何成为一个能为自己项目做出最佳技术选型的工程师。

这本编程指南真是出乎我的意料，远远超出了我对一本技术书籍的期待。我本来以为这会是一本枯燥的理论堆砌，但作者以一种非常实用的方式呈现了内容。书中的项目设计得非常巧妙，它们不仅仅是简单的“Hello World”级别的示例，而是深入到了实际应用场景中，让我能够立即将学到的知识应用到我自己的项目中去。比如，书中对如何构建一个高效的后台数据同步机制的讲解，详尽到每一个API调用的细节和错误处理的边界情况，这对于任何想要开发企业级应用的开发者来说，都是无价之宝。更让我欣赏的是，作者在介绍新技术时，并没有停留在表面，而是深入探讨了其背后的设计哲学和权衡取舍，这使得我不仅学会了“如何做”，更理解了“为什么这么做”。阅读完前几章后，我感觉我对Android的理解深度有了质的飞跃，那些过去困扰我的性能优化和内存管理问题，现在都有了清晰的解决方案和实践路径。这绝对是一本我未来很长时间都会频繁翻阅的工具书，它的价值远超其售价。

我通常对技术书籍的排版和图示要求很高，因为复杂的技术概念如果不能清晰地视觉化呈现，理解起来就会非常吃力。这本书在这方面做得非常出色，几乎可以说达到了艺术品的级别。图表的质量非常高，每一个流程图、架构图都清晰明了，箭头和标签的运用恰到好处，使得即便是最复杂的组件间通信原理，也能一目了然。而且，代码示例的排版也十分考究，高亮和缩进都符合读者的阅读习惯，很多时候我甚至可以直接复制粘贴运行，极大地减少了因格式错误导致的调试时间。这本书的设计者显然深谙“形式服务于内容”的道理。我尤其喜欢它在介绍新的Android Architecture Components（如ViewModel和LiveData）时所使用的对比图，将旧有的回调地狱模式和新的声明式编程范式进行了直观的对比，这种强烈的视觉冲击，比单纯的文字描述有效得多。它真正做到了让阅读体验成为学习过程的一部分，而不是一种负担。

说实话，当我刚打开这本书的时候，我对它的期望值其实挺低的。市面上充斥着太多那种只做表面文章的技术书了，刚看完第一章就觉得味同嚼蜡，根本提不起兴趣继续。但是，这本书的叙事节奏和内容的组织方式却非常抓人。它不是那种按部就班的章节排列，而是通过一系列精心挑选的“项目”来串联起复杂的知识点。这种以终为始的学习方法极大地提高了我的学习效率。举个例子，书中关于自定义View和动画的部分，不是简单地罗列Canvas和Paint的方法，而是构建了一个动态的、响应用户手势的复杂图表组件。作者在讲解每一步时，都会穿插一些经验之谈，比如在处理大规模绘图时如何避免过度绘制，这些都是书本上看不到的“内行话”。读起来就像是跟着一位经验丰富的前辈在旁边指导你做项目一样，不仅学到了技术，还学到了解决实际问题的思路。这对于那些希望快速上手、做出实际成果的开发者来说，简直是福音。

这本书带给我的最直接感受是“自信心的大幅提升”。在阅读之前，我对处理大型、多模块项目的经验比较少，总感觉自己像个“代码搬运工”，而不是真正的架构师。这本书通过其项目驱动的结构，强迫我从全局视角去思考问题。例如，在构建一个涉及到多个模块间依赖和版本控制的项目时，作者不仅给出了依赖配置的示例，还深入讨论了如何设计模块边界以防止循环依赖的产生，以及如何在CI/CD流程中自动化地进行模块间的集成测试。这些内容远远超出了单纯的编码技巧范畴，它们触及到了软件工程的本质。每完成一个项目，我都会有一种强烈的成就感，因为我不是简单地模仿了书中的代码，而是真正理解了如何从零开始构建一个健壮、可维护的生产级应用。这本书，与其说是一本技术书，不如说是一份高级工程师的实战心法，它的影响力会持续地影响我未来的职业发展方向。
