1. Install JAVA 

take a look  " http://joec.tistory.com/522 "

2. download 'android-sdk-linux'

go get it " http://developer.android.com/sdk/index.html "

and extract it to a directory

3. install Android SDK Platform-tools

You can see the text-file "adb_has_moved.txt" in 'tools' directory

------------------------------------------------------------------------------------------------

The adb tool has moved to platform-tools/

If you don't see this directory in your SDK,

launch the SDK and AVD Manager (execute the android tool)

and install "Android SDK Platform-tools"

Please also update your PATH environment variable to

include the platform-tools/ directory, so you can

execute adb from any location.

※ you can also install 'openjdk-6-jdk' by "sudo apt-get install openjdk-6-jdk"...

This is about installing SUN-JAVA JDK.

1.  Downloading

go to "http://www.oracle.com/technetwork/java/javase/downloads/index.html"

and donwload jdk (I got "jdk-7u3-linux-i586.tar.gz")

and extract it. you can see a directory named ""jdk1.7.0_03"

move the directory to "/usr/lib/java/" (create the 'java' directory)

2.  Installing

execute 'sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/java/jdk1.7.0_03/jre/bin/java" 1'

and 'sudo update-alternatives --config java'

If you have another java-jdk, you can see some menus to select.

If you have just one, you can see this...

"There is only one alternative in link group java: /usr/lib/java/jdk1.7.0_03/jre/bin/java

Nothing to configure."

3. Checking

add the directory to PATH.

I did... edit '~/.bashrc' file. 

adding.... 

'export JAVA_HOME=/usr/lib/java/jdk1.7.0_03'

'export PATH=$JAVA_HOME:$PATH'

and excute 'java -version' to check.

you can see this...finally.

-------------------------------------------------------------------------------------

java version "1.7.0_03"

Java(TM) SE Runtime Environment (build 1.7.0_03-b04)

Java HotSpot(TM) Server VM (build 22.1-b02, mixed mode)
