What is Android ?
Android is a complete operating environment based upon the Linux® V2.6
kernel. Initially, the deployment target for Android was the mobile-phone
arena, including
smart phones and lower-cost flip-phone devices. However,
Android's full range of computing services and rich functional support have
the
potential to extend beyond the mobile-phone
market. Android can be useful for other platforms and applications. In this
article, get an introduction to the Android platform and learn how to code
a basic Android application.
Android is the world'd most popular mobile platform. With Android you can use all the Google apps you know and love, plus there are more than 600,000 apps and games available on Google Play to keep you entertained, alongside millions of songs and books, and thousands of movies. Android devices are already smart, and will only get smarter, with new features you won't find on any other platform, letting you focus on what's important and putting you in control of your mobile experience.

- android.jar
- Java archive file containing all of the Android SDK classes necessary to build your application.
- documention.html and docs directory
- The SDK documentation is provided locally and on the Web. It's largely in the form of JavaDocs, making it easy to navigate the many packages in the SDK. The documentation also includes a high-level Development Guide and links to the broader Android community.
- Samples directory
- The samples subdirectory contains full source code for a variety of applications, including ApiDemo, which exercises many APIs. The sample application is a great place to explore when starting Android application development.
- Tools directory
- Contains all of the
command-line tools to build Android applications. The most
commonly employed and useful tool is the
adbutility (Android Debug Bridge). - usb_driver
- Directory containing the necessary drivers to connect the development environment to an Android-enabled device, such as the G1 or the Android Dev 1 unlocked development phone. These files are only required for developers using the Windows platform.
