全书共分三篇，每一篇均有不同的侧重点。

第一篇是勿在浮沙筑高塔，主要是介绍了理解BREW和嵌入式系统所需要的基本知识。其中包括硬件、C语言、编译器和MakeFile等专业性较强的内容。虽然本篇的主要目的是给初学者夯实基础，但是，我相信其中所讲的内容对专业人士也会有一定的参考价值。

第二篇是磨刀不误砍柴工，主要介绍BREW应用程序的开发过程，让我们能够从开发BREW的应用程序的过程中熟悉BREW平台。在本篇中，还推荐了一个基于BREW事件驱动机制的应用程序框架，这个框架采用了状态机的方式实现。通过这个框架，我们可以更加轻松的开发出应用程序。

第三篇是一识庐山真面目，在这一部分里我们剖析了BREW内部的实现方式，这一部分也是本书的重点。从这一篇的内容中我们将了解到BREW是如何使用C语言实现COM机制，BREW内核的工作方式，以及BREW平台中图形系统的结构和一些高级的BREW接口的应用程序。这一篇就是深入BREW内部，分析BREW，为我们的软件系统开发提供参考。

-The book is divided into three, each one have different emphases.



The first chapter is not to build towers in the loose sand, mainly introduces BREW and embedded systems to understand the basic knowledge required. Including hardware, C language, compiler and MakeFile other highly specialized content. Although the main purpose of this is to lay a solid foundation for beginners, but I believe that talking about the content of the professionals will have some reference value.



Second is the Brothers do not mistake firewood industry, introduces the BREW application development process, so that we can develop BREW applications from the course familiar with the BREW platform. In this, it is also recommended an event-driven mechanism based on the BREW application framework that uses a state machine ways. Through this framework, we can more easily develop applications.



Part III is a truth about knowledge, in this section we analyze the internal BREW implementations, this part is also t
