title: Custom AppCompat Theme not changing Overflow icon on older devices
body: <p>Recently I decided to change the <code>Action Overflow Icon</code> on my app. I got it working on Lollipop devices, but it isn't working on my Ice Cream Sandwich and Kitkat device. Note: on both the devices that it does not work on, the action overflow icon has 3 rounded dots, so the theme is changing it to the Material version....just not my version.</p>
  
  <p>My issue is that I cannot get this to work on older devices, but it works on Lollipop.</p>
  
  <p>Before, I would have had to create separate themes for each version, but now that is not needed. Only one theme is recommended.</p>
  
  <h2>Code</h2>
  
  <pre><code>&lt;resources&gt;
  
      &lt;!-- Base application theme. --&gt;
      &lt;style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"&gt;
  
          &lt;item name="android:actionOverflowButtonStyle"&gt;@style/OverflowMenuButton&lt;/item&gt;
          &lt;item name="colorPrimary"&gt;@color/primary&lt;/item&gt;
          &lt;item name="colorPrimaryDark"&gt;@color/primary_dark&lt;/item&gt;
          &lt;!--&lt;item name="colorPrimaryLight"&gt;@color/primary_light&lt;/item&gt;--&gt;
          &lt;item name="colorAccent"&gt;@color/accent&lt;/item&gt;
          &lt;item name="android:textColorPrimaryInverse"&gt;@color/primary_text_light&lt;/item&gt;
          &lt;item name="android:textColorPrimary"&gt;@color/primary_text&lt;/item&gt;
          &lt;item name="android:textColorSecondary"&gt;@color/secondary_text&lt;/item&gt;
          &lt;!--&lt;item name="icons"&gt;@color/icons&lt;/item&gt;--&gt;
          &lt;item name="divider"&gt;@color/divider&lt;/item&gt;
  
      &lt;/style&gt;
  
      &lt;style name="OverflowMenuButton" parent="@style/Widget.AppCompat.ActionButton.Overflow"&gt;
          &lt;item name="android:src"&gt;@drawable/ic_star_rate_white_18dp&lt;/item&gt;
      &lt;/style&gt;
  
  
  &lt;/resources&gt;
