How To install Android environment:

Here’s a quick start installation guide to get you up and running with the Google Android Software Development Kit (SDK). This guide will describe how to install the Android SDK and set up your chosen development environments. If you’ haven’t already done so you can download the Android SDK from the link below, then we can get started.

First you’ll need to download the Android SDK source files:
( http://code.google.com/android/download.html )

System Requirements

In order to first use the Android SDK code and tools for development you will of course need a suitable environment develop from.

Currently the following operating systems are supported:

• Windows XP or Vista
• Mac OS X 10.4.8 or later (x86 only)
• Linux (tested on Linux Ubuntu Dapper Drake)

You will also need to install a suitable development environment such as:

1. Eclipse
2. JDK (Java Development Kit)
3. Android SDK
4. ADT (Android Development Tools)

1.Installing the Eclipse:

1. Download and install Eclipse IDE latest version or 3.2 or 3.3 or above. Recommended version is “Eclipse IDE for Java Developers”

                                  http://www.eclipse.org/downloads/.

Ø  For Windows, The Eclipse download comes as a big ZIP file that you install by extracting the files to your favorite directory. We’ll assume that you extracted to C:/eclipse.

Ø  For Mac OS X, The Eclipse download comes as a big tar ball (.gz file) that you install by extracting             the files to your favorite directory. we'll assume that you extracted to /usr/lib/eclipse.

2.Installing the JDK:

1. Install JDK (Java Development Kit) version 5.0 or 6.0.

Ø  For Windows, you can go to http://java.sun.com/javase/downloads and choose JDK 6 Update.

Ø  In Mac OS X, we don't need to do this as JDK (5.) is built-in installed with Mac OS X.

3.Installing the Android SDK

First you will need to download the Android SDK pack .zip archive, once downloaded find a suitable installation location on your machine and extract the zipped files.

Mac OS X

1. In the home directory locate the .bash_profile and locating the PATH variable add the location to your $SDK_ROOT/tools folder.

Windows XP / Vista

1. Download the latest Android SDK.
2. Unzip to C:\AndroidSDK
3. Right-click on (My) Computer, and select Properties
4. Go to Advanced settings
• XP: Click the Advanced tab
• Vista/7: Click Advanced system settings on the left
5. Click the Environment Variables button
6. double-click on Path (under System Variables)
7. Add the full path to the tools/ directory:

C:\AndroidSDK\tools\

(Make sure a semicolon (;) separates this new path from all the others)

The Android SDK also requires a suitable development environment to work in, here’s the installation guides for each of the supported environments.
