Android : Integrating the FB SDK in Android project

I have a working android project. I'm trying to integrate the Facebook SDK for android. As I see in the installation instructions.. I need to unzip the package.Then import the facebook folder as a project. Then in my project in properties ads a new library and choose the facebooksdk project. When I do this I'm getting error

Jar mismatch! Fix your dependencies

Which is for the android-support-v4.jar file. I have once the that file in my project libs folder and again in the facebookSDK project. If I make them the same files (copy one over the other) I'm getting errors in the FacebookSDK project...

I'm really confused,can you please help to work this out =]
