title: Facebook SDK for Android duplicate support library on dependencies
body: <p>I have implemented the new Facebook SDK 3.0 beta. The library project contains the Android support library v4. I also have the support library on my own proyect (a different version though). When I add the Facebook SDK as a library I get the next error on the console:</p>
  
  <pre><code>Jar mismatch! Fix your dependencies
  Found 2 versions of android-support-v4.jar in the dependency list,
  but not all the versions are identical (check is based on SHA-1 only at this time).
  All versions of the libraries must be the same at this time.
  </code></pre>
  
  <p>I've tried to exclude the <code>libs</code> folder on the buildpath, but the error remains.</p>
  
  <p>I have to put the same .jar in both places. Am I missing something here? The idea is to use the support library of my own project (to keep it updated).</p>
