title: Error:(28, 34) error: package android.support.annotation does not exist
body: <p>After importing an Eclipse ADT project into Android Studio, I'm seeing these errors:</p>
  
  <p><code>Error:(28, 34) error: package android.support.annotation does not exist</code></p>
  
  <p><code>Error:(34, 34) error: package android.support.v4.content does not exist</code></p>
  
  <p><code>Error:(26, 30) error: package android.support.v4.app does not exist</code></p>
  
  <p>I have installed the Android Support Library and Repository through SDK Manager, and here's my dependencies in the build.grade file for the module:</p>
  
  <pre><code>compile project(':pullToRefreshListView')
  compile project(':facebook')
  compile 'com.android.support:support-v4:23.3.0'
  compile 'com.android.support:design:23.3.0'
  compile 'com.google.android.gms:play-services:+'
  compile 'com.actionbarsherlock:actionbarsherlock:4.4.0@aar'
  compile files('libs/google-play-services.jar')
  </code></pre>
  
  <p>Not sure why it doesn't see the Android support library. </p>
