Download the Android SDK

ADT Plugin for Eclipse 

Installing the SDK 

Create Android Emulator

The Android SDK includes a mobile device emulator -- a virtual mobile device that runs on your computer. The emulator lets you prototype, develop, and test Android applications without using a physical device.

The Android emulator mimics all of the hardware and software features of a typical mobile device, except that it can not receive or place actual phone calls. It provides a variety of navigation and control keys, which you can "press" using your mouse or keyboard to generate events for your application. It also provides a screen in which your application is displayed, together with any other Android applications running.

Steps to create a emulator

Open eclipse
Window>Android SDK and AVD Manager

It will shows the Android SDK and AVD Manager

In that Virtual Device click that new Button

 Fill the name and all.
