Setup Java Development Kit (JDK)

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 have 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, then Environment 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’s official website: http://developer.android.com/sdk/index.html. If you are installing SDK on Windows machine, then you will find ainstaller_rXX-windows.exe, so just download and run this exe which will launch Android SDK Tool Setup wizard to guide you throughout the installation, so just follow the instructions carefully. Finally, you will have Android 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

Once you launched SDK manager, it is time to install other required packages. By default it will list down total 7 packages to be installed, but we will suggest to de-select Documentation for Android SDK and Samples for SDK packages to reduce installation time. Next click the Install 7 Packages button to proceed If you agree to install all the packages, select Accept All radio button and proceed by clicking Install button. 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.

Step 3 -Setup Eclipse IDE 

All the examples in this tutorial have been written using Eclipse IDE. So we would suggest you should have latest version of Eclipse installed on your machine. To install Eclipse IDE, download the latest Eclipse binaries from http://www.eclipse.org/downloads/. Once you have downloaded the installation, unpack the binary distribution into a convenient location. For example in C:\eclipse on windows, or /usr/local/eclipse on Linux and finally set PATH variable appropriately. Eclipse can be started by executing the following commands on windows machine, or you can simply double click on eclipse.exe %C:\eclipse\eclipse.exe Eclipse can be started by executing the following command on Linux machine: $/usr/local/eclipse/eclipse

Step 4 -Setup Android Development Tools (ADT) Plugin 

This step will help you in setting Android Development Tool plugin for Eclipse. Let's start with launching Eclipse and then, choose Help > Software Updates > Install New Software. This will display the following dialogue box.
Now use Add button to add ADT Plugin as name and https://dlssl.google.com/android/eclipse/ as the location. Then click OK to add this location. As soon as you will click OK button to add this location, Eclipse starts searching for the plug-in available in the given location and finally lists down the found plugins.
Now select all the listed plug-ins using Select All button and click Next button which will guide you ahead to install Android Development Tools and other required plugins.
