I setup a old notebook with the newest Fedora 13 recently. The first job is to install Android development environment. The Eclipse was installed using Fedora's Add/Remove Software. Because the default setting of the Eclipse setup, I face the error "Cannot complete the install because one or more required items could not be found" again. It's because the Galileo Download site is not included.
To solve it adding the following site in Eclipse Available Software Sites list.
For details to install Install Android SDK on Eclipse, in Ubuntu, refer here.
