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:
- Eclipse
- JDK
(Java Development Kit)
- Android
SDK
- ADT
(Android Development Tools)
1.Installing
the Eclipse:
- Download and install Eclipse IDE latest version or 3.2
or 3.3 or above. Recommended version is “Eclipse IDE for Java
Developers”
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.
- Install
JDK (Java Development Kit) version 5.0 or 6.0.
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
- 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
- Download
the latest Android SDK.
- Unzip
to C:\AndroidSDK

on (My) Computer, and select Properties
- Go
to Advanced settings
- XP:
Click the Advanced tab
- Vista/7:
Click Advanced system settings on the left
- Click
the Environment Variables button
- double-click
on Path (under System Variables)
- 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.
