title: java.lang.NoClassDefFoundError: android.support.v4.content.LocalBroadcastManager facebook android app
body: <p>I know this question has been asked and I've tried using many other posts to help me through this but none have worked. I am working through this link to install a Facebook login onto an Android app: <a href="https://developers.facebook.com/docs/android/getting-started" rel="noreferrer">https://developers.facebook.com/docs/android/getting-started</a>. I have imported the Facebook SDK and it works for the sample apps so I know thats ok. I DO NOT have any JARs in my libs folder. In properties > Android libraries I have added appcompat_v7 and FacebookSDK. In Built Path > Order and Export I have Android Dependencies and Android Private Libraries both checked.</p>
  
  <p>The error </p>
  
  <p><code>java.lang.NoClassDefFoundError: android.support.v4.content.LocalBroadcastManager</code></p>
  
  <p>happens on this line of code:</p>
  
  <p><code>Session.openActiveSession(this, true, new Session.StatusCallback() {</code></p>
  
  <p>Any ideas on why this is happening? I have been messing around with my properties all day and can't get it working. The code is right off of the FB developer site so I'm sure its fine. Thanks.</p>
