                                Environment Setup






You will be glad to know that you can start your Android application development on either of the following
operating systems:




  •  Microsoft Windows XP or later version.
  • Mac OS X 10.5.8 or later version with Intel chip.
  • Linux including GNU C Library 2.7 or later.



Second point is that all the required tools to develop Android applications are freely available and can be
downloaded from the Web. Following is the list of software's you will need before you start your Android application
programming.

  •  Java JDK5 or JDK6
  • Android SDK
  • Eclipse IDE for Java Developers (optional)
  • Android Development Tools (ADT) Eclipse Plugin (optional)





Here last two components are optional and if you are working on Windows machine then these components make
your life easy while doing Java based application development. So let us have a look how to proceed to set
required environment.



Step 1 - Setup Java Development Kit (JDK)

You can download the latest version of Java JDK from Oracle's Java site: Java SE Downloads. You will find
instructions for installing JDK in downloaded files, follow the given instructions to install and configure the setup.
Finally set PATH and JAVA_HOME environment variables to refer to the directory that contains java and javac,
typically java_install_dir/bin and java_install_dir respectively.
If you are running Windows and installed the JDK in C:\jdk1.6.0_15, you would have to put the following line in
your C:\autoexec.bat file.

 
set PATH=C:\jdk1.6.0_15\bin;%PATH%

set JAVA_HOME=C:\jdk1.6.0_15





Alternatively, you could also right-click on My Computer, select Properties, then Advanced, thenEnvironment
Variables. Then, you would update the PATH value and press the OK button.
On Linux, if the SDK is installed in /usr/local/jdk1.6.0_15 and you use the C shell, you would put the following code
into your .cshrc file.


 
setenv PATH /usr/local/jdk1.6.0_15/bin:$PATH

setenv JAVA_HOME /usr/local/jdk1.6.0_15


Alternatively, if you use an Integrated Development Environment (IDE) Eclipse, then it will know automatically
where you have installed your Java.

Step 2 - Setup Android SDK

You can download the latest version of Android SDK from Android official website : Android SDK Downloads. If you
are installing SDK on Windows machine, then you will find a installer_rXX-windows.exe, so just download and run
this exe which will launch Android SDK Tool Setup wizard to guide you throughout of the installation, so just follow
the instructions carefully. Finally you will haveAndroid SDK Tools installed on your machine.
If you are installing SDK either on Mac OS or Linux, check the instructions provided along with the
downloaded android-sdk_rXX-macosx.zip file for Mac OS and android-sdk_rXX-linux.tgz file for Linux. This tutorial
will consider that you are going to setup your environment on Windows machine having Windows 7 operating
system.
So let's launch Android SDK Manager using the option All Programs > Android SDK Tools > SDK Manager, this
will give you following window:

SDK packages to reduce installation time. Next click Install 7 Packages button to proceed, which will display
following dialogue box:


If you agree to install all the packages, select Accept All radio button and proceed by clicking Installbutton. Now
let SDK manager do its work and you go, pick up a cup of coffee and wait until all the packages are installed. It
may take some time depending on your internet connection. Once all the packages are installed, you can close
SDK manager using top-right cross button.



again later Steps are as follows by the Software! 
I will Explained you Later............................................................................
