Eclipse is a Software Development Environment that supports multiple languages and comprises of Integrated Development Environment (IDE) and an extensible Plug-in system. It is Java based and can be used to develop Applications in Java with the help of other plug-Ins and languages like C/C++, COBOL, Python and many more. It is primarily for Java Developers but users can extend its capabilities by installing Plug-Ins written for the Eclipse Software Framework.

Android is a popular name in the world of mobile phones and computers. It is moreover a software stack that includes Operating System, Middleware, and key Applications. The applications are JAVA based Object Oriented Applications running on a Dalvik Virtual machine. The features included range from traditional i.e. Bluetooth, Media support (MPEG4, H.264, AAC, AMR, GIF etc) to modern i.e. WiFi, EDGE, 3G GPS and Accelerometer. Since it is Java based system, the applications run in their own process with their own instance of the Dalvik Virtual machine. It also helps the device to run multiple VMs (Virtual machine) It comes with An Application Framework for reuse and replacement of components and a rich Development Environment including device emulator, a plug-in for Eclipse IDE and tools for debugging, and memory and performance profiling. Android provides developers to have full access to the same framework APIs used by the core applications and thus build extremely rich and innovative applications.

The Android SDK (Software Development Kit) is a most useful developing tool that allows the creation of Applications in Eclipse. SDK uses Eclipse as an add-on software for the development of Applications. SDK is often termed as Driver Development Kits (DDK) for specific systems or sub-systems.

Installing the Android SDK into Eclipse is a simple task. Now you follow some instructions listed below to get it done:

Step 1: To install Android SDK on your computer, first you have to download and install Java 6 SDK from the following page:http://java.sun.com/javase/downloads/index.jsp.

In case Java SDK is installed in your computer then make sure it is at least Java 5 SDK.

Step 2: Now you have to install Eclipse 3.5 by downloading it from:http://www.eclipse.org/downloads/

If you are having it than make sure that it is at least Eclipse 3.4. After this download the latest Android SDK from: http://developer.android.com/sdk/index.html

You should unzip the package to a location and that you will not delete in future and remember it. Now add this location to your system path.

Step 3: After this install the ADT (Android Development Tools) plug-ins for Eclipse by using the following instructions: http://developer.android.com/sdk/eclipse-adt.html

Now use the AVD (Android Virtual Devices) Manager to download the latest Files and other SDKs that you may like to support. With this you are ready to work on Your Android Projects.

Android SDK is an important tool for developing Applications. The Android 0.9 SDK is provided an updated and extended API (Application Programming Interface), improved development tools and an updated design for the home-screen. The latest versions comes with; search by voice, alarm clock fixes, sending Gmail freeze fix and refreshing intervals. Some special features also include, video recording, support for Stereo Bluetooth profile and customising onscreen keyboard.

So, open your Computer and star developing Applications and turn your great App idea into reality.
