title: Android/Facebook: Project is missing required library
body: <p>I have imported the Facebook SDK downloading it there : <a href="https://github.com/facebook/facebook-android-sdk/commits/master" rel="nofollow">https://github.com/facebook/facebook-android-sdk/commits/master</a> and following the instructions there <a href="http://www.android10.org/index.php/articleslibraries/290-facebook-integration-in-your-android-application" rel="nofollow">http://www.android10.org/index.php/articleslibraries/290-facebook-integration-in-your-android-application</a></p>
  
  <p>I have added FacebookSDK as a Library for my current project.</p>
  
  <p>But I have errors in all the Samples imported when I import the facebook project:
  "Project FacebookSDK is missing required library libs/android-support-v4.jar" appears as one error for FacebookSDK project
  And then I have 
  "The container 'Android Dependencies' references non existing library C:...\facebook-android-sdk-master\facebook\bin\facebooksdk.jar" for all the facebook sample projects that are in the facebook project.</p>
  
  <p>I tried to clear the project, to do Properties > Java Compiler > Compiler compliance level 1.6 (because 5.0 or 6.0 level was needed, not 1.7, so I downloaded jdk 1.6)
  tried to do Android Tools > Fix project properties</p>
  
  <p>But I still have the same erros...
  Could someone tell me what I should do?
  Thanks</p>
