Welcome to the Android Dev Guide! The Dev Guide is a practical introduction to developing applications for Android. It explores the concepts behind Android, the framework for constructing an application, and the tools for developing, testing, and publishing software for the platform.
欢迎来到Andoid开发者指南！该指南是开发Android应用的实践介绍。她探索了Android背后的概念，构成应用的框架和针对平台进行开发、测试以及发布软件的各种工具。
The Dev Guide holds most of the documentation for the Android platform, except for reference material on the framework API. For API specifications, go to the Reference tab above.
开发者指南包括了Android平台的绝大多数文档，但不包括框架API的参考内容。请到“参考”标签下获取API规范。
As you can see in the panel on the left, the Dev Guide is divided into a handful of sections. They are:
开发者指南深入一下几个章节。她们是：
Android起步：她是什么？她能用来做什么？她如何适用于你的应用？
Discussions of particular parts of the Android framework and API. For an overview of the framework, begin with Application Fundamentals. Then explore other topics — from designing a user interface and setting up resources to storing data and using permissions — as needed.
讨论了Android框架与API的特定部分。请从“应用基础”开始，了解框架的概览。接着可以探索其他的话题——根据你的需要——从设计用户界面和配置资源开始，到存储数据和使用授权。
Developing：开发
Directions for using Android's development and debugging tools, and for testing the results.
关于Android的开发/调试工具，以及测试结果的指导。
Publishing：发布
Instructions on how to prepare your application for deployment and how to publish it when it's ready.
当应用以就绪，这里介绍了如何为部署准备你的应用，以及如何发布应用。
Recommendations on preferred techniques for writing applications that perform efficiently and work well for the user.
建议：针对用户，编写应用时有效执行和良好工作的首选技术。
Step-by-step tutorials and sample code demonstrating how an Android application is constructed.
手把手的教程，还有范例代码；她们展示了Andorid应用是如何构成的。
Appendix：附录
Reference information and specifications, as well as FAQs, a glossary of terms, and other information.
参考信息和规范，还有FAQs，术语的词汇表，以及其他的信息。
The first step in programming for Android is downloading the SDK (software development kit). For instructions and information about the kit, go to the SDK tab above.
编程的第一步，是下载SDK（软件开发包）。去SDK标签页，获取有关开发包的指令和信息。
After you have the SDK, begin by looking over the Dev Guide. If you want to start by getting a quick look at the code, the short Hello World tutorial walks you through a standard "Hello, World" application as it would be written for the Android platform. The Application Fundamentals document is a good place to start for an understanding of the application framework.
当你有了SDK，就可以纵观这份开发者指南。如果你想要快速纵览代码，可以看看较短的Hello World教程，她会带领你看看在Android平台下的“Hello World”应用。而应用基础文档，则是理解应用框架的好地方。
