Why is the actionbar so tall on Nexus 7?
<p>For my own entertainment, I'm writing my first android app. On my Nexus 7 in portrait mode, the actionbar looks too tall, for example it is considerably taller than the one in the gmail app (<a href="http://www.flickr.com/photos/matthelliwell/8526407062/" rel="nofollow">http://www.flickr.com/photos/matthelliwell/8526407062/</a>)</p>

<p>I've ran the same app on an HTC Sensation phone and the actionbar looked more like the height I would expect it. For the style I'm using Theme.Holo.Light with showHome set:</p>

<pre><code>&lt;resources&gt;
  &lt;style name="GedcomTheme" parent="android:style/Theme.Holo.Light"&gt;
    &lt;item name="android:actionBarStyle"&gt;@style/GedcomActionBarStyle&lt;/item&gt;
    &lt;item name="android:textViewStyle"&gt;@style/GedcomTextView&lt;/item&gt;
    &lt;item name="android:editTextStyle"&gt;@style/GedcomEditText&lt;/item&gt;
  &lt;/style&gt;

  &lt;style name="GedcomTextView" parent="android:Widget.TextView"&gt;
    &lt;item name="android:textAppearance"&gt;?android:attr/textAppearanceSmall&lt;/item&gt;
  &lt;/style&gt;

  &lt;style name="GedcomEditText" parent="android:Widget.EditText"&gt;
    &lt;item name="android:textAppearance"&gt;?android:attr/textAppearanceSmall&lt;/item&gt;
  &lt;/style&gt;

  &lt;style name="GedcomActionBarStyle" parent="@android:style/Widget.Holo.ActionBar"&gt;
    &lt;item name="android:displayOptions"&gt;showHome&lt;/item&gt;
  &lt;/style&gt;
&lt;/resources&gt;
</code></pre>

<p>The menu itself is created as:</p>

<pre><code>&lt;menu xmlns:android="http://schemas.android.com/apk/res/android"&gt;
    &lt;item
        android:id="@+id/open_menu_item"
        android:title="Open"
        android:icon="@drawable/ic_menu_archive"
        android:showAsAction="ifRoom"/&gt;
    &lt;item
        android:id="@+id/delete_menu_item"
        android:title="Delete"
        android:icon="@drawable/ic_menu_delete"
        android:showAsAction="ifRoom"/&gt;
&lt;/menu&gt;

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.home_menu, menu);
    return true;
}
</code></pre>

<p>So how do I shrink it on the Nexus without making it excessively small on other devices?</p>
