Install sun jdk on ubuntu 10.10

Android requires JDK5.0 to build the source code (at the time of writing).

(When build Android, the java and javac version is checked by */build/core/main.mk)

So, you need to: download and install the JDK5.0 from Sun's (Oracle's) website, or, use the old repositories:

1a. For Java 5, Add Jaunty to repositories

$ sudo add-apt-repository "deb http://us.archive.ubuntu.com/ubuntu/ jaunty multiverse"

1b. For Java 6, Add Jaunty to repositories

$ sudo add-apt-repository ppa:sun-java-community-team/sun-java6

2. Update source list  

$ sudo apt-get update

3. Install 

$ sudo apt-get install sun-java6-jdk (or sun-java5-jdk)
