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
How can I uninstall Java version "1.6.0_24" and install Java SE 1.6? I have alien installed so I can install .rpm packages.

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
