android SDK manager, only show installed package

Question

There is something wrong with my SDK manager, which only show the installed package. I couldn\'t install the others.

*I downloaded the ADT bundle for windows from htt

Answer 1

Manager is unable to load list of packages from repository, probably it's proxy or firewall issue (as I know, it uses standard http). So, it just doesn't know anything about non-installed packages.

Check your internet connection and try again (there is a button "Reload" in the "Packages" menu)
