title: Android ActionBar Not Appearing
body: <p>I know, this sounds dumb, but bear with me.</p>
  
  <p>I use the following</p>
  
  <pre><code>android:minSdkVersion="8"                
  android:targetSdkVersion="17"
  android:Theme.Holo"
  </code></pre>
  
  <p>When I run my app on 2.2 emulator, the menu button brings up my menu.</p>
  
  <p>Whhen I run my app on 4.2 emulator, should the action bar not automatically be activated? I can see program icon + title. I have added some menu items like this:</p>
  
  <pre><code>&lt;item android:id="@+id/itemShare" android:title="@string/titleShare"
      android:icon="@android:drawable/ic_menu_share"
      android:showAsAction="ifRoom"&gt;&lt;/item&gt;
  </code></pre>
  
  <p>I then have defined</p>
  
  <pre><code>onCreateOptionsMenu
  </code></pre>
  
  <p>all my activies inherit from.</p>
  
  <p>Yet, I see nothing "action bar" icons when running my app in 4.2 emulator. I must be missing something obvious.</p>
  
  <p>I am very new to Android and Eclipse, but I am slightly confused of above. The way I do it, should that not be the way to get pre/post honeycomb compability assuming one does not want to use ActionbarSherlock?</p>
