I’ve been playing around with getting started building Android (I’d like to get 2.0 working on my Joggler). To build Android under Linux, you need the sun-java5-jdk package.

This is due to a conflict in the @Override command, which means you can’t use the Java 6 JDK for this task.

Unfortunately the sun-java5-jdk package isn’t available by default in the Karmic or Lucid repositories, so you need to grab it from somewhere else. To save you searching, here’s the howto:

1. Enable the jaunty-updates multiverse repository

You can do this by adding a single line to your sources.list file.

First, open your sources.list with the command:

sudo vim /etc/apt/sources.list

Then you can add the following line (making sure you comment – # – with why you added it) to the file:

deb http://cz.archive.ubuntu.com/ubuntu jaunty-updates main multiverse

Then you can save that and quit.

2. Refresh sources

You need to do an update to refresh your repository list then you’re good to go:

sudo apt-get update

3. Install package

And finally to install:

sudo apt-get install sun-java5-jdk

4. Continue process
