today i update the android SDK Tools to rev22.2
and then i can't create new android application project.
it tells me that the Android Support library is either not installed or need to update.
but ver.18 is the newest version of Android Support library!
i pressed the Install/Upgrade button but nothing happened.
i used Android SDK manager tried to uninstall and install the android support library again, restart the Eclipse, restart the computer, but all these can't fix the situation.
now i don't know what to do...
the version of Eclipse is Kepler ver.4.3.0
