The thread http://ubuntuforums.org/showthread.php?t=1473194 is closed, but the problem persists:

Android development requires eclipse and ant1.8.

If you install eclipse in Ubuntu 10.4 and then ant1.8, the second 'apt-get install' removes eclipse.

If you install ant1.8 first and then eclipse, the latter fails with this message:
Code:
The following packages have unmet dependencies:
  eclipse: Depends: eclipse-jdt but it is not going to be installed
           Depends: eclipse-pde but it is not going to be installed
E: Broken packages
Has there been any progress?
