The Developer's Guide

Welcome to the Android Dev Guide! The Dev Guide provides a practical introduction to developing applications for Android and documentation about major platform features. It explores the concepts behind Android, the framework for constructing an application, and the tools for developing, testing, and publishing software for the platform.

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.

As you can see in the panel on the left, the Dev Guide is divided into several sections:

Android Basics
An initial orientation to Android — what it is, what it offers, and how your application fits in.
Framework Topics
Discussions of particular parts of the Android framework and API. For an introduction to 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.
Android Market Topics
Documentation for topics that concern publishing and monetizing applications on Android Market, such as how to enforce licensing policies and implement in-app billing.
Developing
Directions for using Android's development and debugging tools, and for testing the results.
Publishing
Instructions on how to prepare your application for deployment and how to publish it when it's ready.
Best Practices
Recommendations on preferred techniques for writing applications that perform efficiently and work well for the user.
Web Applications
Documentation about how to create web applications that work seamlessly on Android-powered devices and create Android applications that embed web-based content.
Appendix
Reference information and specifications, as well as FAQs, a glossary of terms, and other information.

The first step in programming for Android is downloading the SDK (software development kit). For instructions and information, visit the SDK tab.

After you have the SDK, begin by looking through the Dev Guide. If you want to start by getting a quick look at some code, the Hello World tutorial walks you through a standard "Hello, World" application to introduce some basics of an Android application. The Application Fundamentals document is a good place to start learning the basics about the application framework.

For additional help, consider joining one or more of the Android discussion groups. Go to the Developer Forums page for more information.

To return to this page later, just click the "Dev Guide" tab while any Dev Guide page is loaded.
