title: Import 3 SDKs, get error: Found 3 versions of android-support-v4.jar
body: <p>I create an Android-application.
  Have imported all my SDKs (GoogleSDK, FacebookSDK, AppCompatSDK)</p>
  
  <p>Right-click on my <strong><em>project -> properties -> Android -> Add</em></strong> my 3 SDKs.
  Press on Apply and get this error:</p>
  
  <blockquote>
    <p><strong>Found 3 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.</strong></p>
  </blockquote>
  
  <p>What should I do?
  The project isnt red, there is nothing red in <em>Order and Export, &amp; Libraries</em></p>
  
  <p>( This app will work from API 8 &amp; above )</p>
  
  <p>P.S
  <em>If you know any link to a good tutorial there it shows how to make loginbutton for FacebookSDK 3.5, login and go back to a new Activity would be nice. Just login &amp; signout, nothing more.</em></p>
  
  <p>Thank you.</p>
