title: the android studio instantly remove my copy & paste import statement
body: <p>i've a project (blank activity) set up by android studio 0.8x, but when i paste (ctrl + v) some import statement like the following</p>
  
  <pre><code>import android.app.Activity;
  import android.content.res.Resources;
  import android.graphics.drawable.TransitionDrawable;
  import android.os.Bundle;
  import android.widget.ImageView;
  </code></pre>
  
  <p>the android studio will automatically rollback (ctrl + z) and only default import statement will stay, so i can't use any custom import statement  now, what the matter is going on?</p>
