title: Android: invalid parent reference
body: <p>Things get weird when I using Android Studio 3.0 to open a project which was programmed under Android Studio in an older version, after <code>sync</code>, this piece of code didn't work which was programmed by my friend, but I just can't figure it out that why it doesn't work.</p>
  
  <pre><code> &lt;style name="MyActionBar.MenuTextStyle"
      parent="style/TextAppearance.AppCompat.Widget.ActionBar.Title"&gt;
      &lt;item name="android:textColor"&gt;@color/colorLightPurple&lt;/item&gt;
      &lt;item name="android:textSize"&gt;14sp&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
