title: Android Rotation Problem with onConfigurationChanged
body: <p>I gave <code>android:configChanges="orientation|keyboard"</code> to my activity in manifest and when I rotate my device, <code>onConfigurationChanged</code> is always called. No problem with it.</p>
  
  <p>What I want is when device is rotated, font size of widget become changed.</p>
  
  <pre><code>&lt;TextView android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:textSize="@dimen/my_font_size" /&gt;
  </code></pre>
  
  <p>Like above, <code>textSize</code> attribute refer the value in resource
  and the xml file defining <code>my_font_size</code> is in values-land, values-port folders.</p>
  
  <p>Ok. I'm ready. Build it, run it, and rotate the device, and there is no change.
  requestLayout() in onConfigurationChanged() doesn't work.
  Any advise about it?</p>
  
  <p>Thanks.</p>
