title: Animation cannot be resolved to a type
body: <p>i'm writing</p>
  
  <pre><code>Animation anIn;
  </code></pre>
  
  <p>but Animation error,</p>
  
  <pre><code>Animation cannot be resolved to a type;
  </code></pre>
  
  <p>and I don't want to import</p>
  
  <pre><code>android.view.animation;
  </code></pre>
  
  <p>I want to use <code>nineoldandroids</code> library. So import that library project to work-space, then right click on my project , properties, and in Android Tab reference to library in work-space.
  now i can see com.nineoldandroids imports.
  but error exist yet!</p>
  
  <p>what's wrong?
  how can i change a sample from android animation imports to <code>nineoldandroids</code> imports?</p>
