title: android:windowActionBarOverlay & android:actionBarStyle requires api level 11
body: <p>I am making an android app and using android-support-v7-appcompat to make sure my app support action bars from android version 2.2 and up.</p>
  
  <p>I need to make the Action Bar overlay and use a translucent background so I have modified the styles.xml to this code :</p>
  
  <pre><code>    &lt;resources&gt;
  
      &lt;style name="AppBaseTheme" parent="android:Theme.Light"&gt;
          &lt;!--
              Theme customizations available in newer API levels can go in
              res/values-vXX/styles.xml, while customizations related to
              backward-compatibility can go here.
          --&gt;
      &lt;/style&gt;
  
      &lt;!-- Application theme. --&gt;
      &lt;style name="AppTheme" parent="AppBaseTheme"&gt;
          &lt;!-- All customizations that are NOT specific to a particular API-level can go here. --&gt;
      &lt;/style&gt;
  
      &lt;!-- TRANSLUCENT THEME --&gt;
      &lt;style name="TranslucentAB" parent="Theme.AppCompat.Light"&gt;
          &lt;item name="windowActionBarOverlay"&gt;true&lt;/item&gt;
          &lt;item name="android:windowActionBarOverlay"&gt;true&lt;/item&gt;
          &lt;item name="android:actionBarStyle"&gt;@style/BlackBar&lt;/item&gt;
          &lt;item name="actionBarStyle"&gt;@style/BlackBar&lt;/item&gt;
      &lt;/style&gt;
  
      &lt;!-- TRANSLLUCENT COLOR STYLE --&gt;
      &lt;style name="BlackBar" parent="@style/Widget.AppCompat.Light.ActionBar.Solid.Inverse"&gt;
          &lt;item name="android:background"&gt;@drawable/halfblack&lt;/item&gt;
          &lt;item name="background"&gt;@drawable/halfblack&lt;/item&gt;
      &lt;/style&gt;
  
  &lt;/resources&gt;
  </code></pre>
  
  <p>and modified manifest file to adapt the new ActionBar as :</p>
  
  <pre><code>android:theme="@style/TranslucentAB"
  </code></pre>
  
  <p>The problem is that the following two lines of code require API level 11 and up :</p>
  
  <pre><code>&lt;item name="android:windowActionBarOverlay"&gt;true&lt;/item&gt;
  &lt;item name="android:actionBarStyle"&gt;@style/BlackBar&lt;/item&gt;
  </code></pre>
  
  <p>but I need to support from API level 8 and up. If I remove these two lines the app runs fine on Android 2.2 with black translucent action bar. But if I run the app in Android 4.3 the app launches with a solid white action bar. halfblack is just a png file in drawable folder with 70% black color.</p>
