I am trying to update my Android SDK Tools to 17 rev. and I updated usign SDK Tools but in Properties/library ;
But the fact that in the support folder there is a annotations.jar already. What should I do to fix it?
I had the same problem. I went to the SDK Manager within eclipse (Window --> Android SDK Manager) and installed the Android Support package which is found in the Extras folder. After the install the error was gone (at least in my system)
