How can I uninstall my current java and install sun java 1.6

I installed jdk using the following command: sudo apt-get install default-jdk but it is the wrong version. I need Java SE 1.6 for building Android. When I try building Android, I get a message: Checking build tools versions...

You are attempting to build with the incorrect version of java.

Your version is: java version "1.6.0_24". The correct version is: Java SE 1.6.

Please follow the machine setup instructions at

1.) If you’ve already installed OpenJDK (Or in Ubuntu generally it is already installed). Remove it by running this command:

sudo apt-get purge openjdk*

2.) Then:

sudo add-apt-repository ppa:webupd8team/java

Then update:

sudo apt-get update

3.) Select which version you want To install Oracle Java 8:

sudo apt-get install oracle-java8-installer

To install Oracle Java 7:

sudo apt-get install oracle-java7-installer

To install the Java 6:

sudo apt-get install oracle-java6-installer

You can install the Java 6 JDK from Ubuntu's own repository by running the following line in the terminal:

sudo apt-get install openjdk-6-jdk

However, I'm running Eclipse, the Android SDK and I'm able to compile and run Android applications with OpenJDK 7 installed. It can be installed with:

sudo apt-get install openjdk-7-jdk
