The android developer guide suggests you install ia32-libs when developing on a 64bit platform. However this installs some 242 packages. A much more sensible option is to only install the 32bit libraries that are actually needed and then you only have to install 57 new packages. Additionally Quantal Quetzal comes with an up to date version of eclipse (3.8) so you can install this via the package manager as well instead of downloading 3.7 as the guide suggests.
To install the packages simply run the following command:
sudo apt-get install eclipse libgl1-mesa-dev:i386 libsdl1.2debian:i386
The installation of eclipse will also provide a compatible Java runtime required for building android apps.
