There is no android support package in my SDK manager, as shown:

And whenever I try to create an android application project I am presented with this screen at the end:

If I click install/upgrade this appears:

And it installs and everything, but nothing happens and it stays on the same screen as before. Clicking check again doesn’t do anything either.
How can I get this to work?
For some weird reason android-sdk decided to install everything in
/extras/compatibilityinstead of/extras/supportwhich eclipse recognises, so I renamed/extras/compatibilityto/extras/supportand now everything works fine.
