title: Set android window title bar icon from custom application theme
body: <p>Is it possible to set the window title bar title and icon from my own custom theme?
  when i create a new Android project in eclipse and have it use AppTheme as shown here</p>
  
  <pre><code>&lt;style name="AppTheme" parent="android:Theme.Light" /&gt;
  </code></pre>
  
  <p>the window title bar title and icon appear as i want them.</p>
  
  <p>When i select my own theme in the mainfest file only the title shows in the window title bar and not the icon.</p>
  
  <p>My theme is as follows</p>
  
  <pre><code>style name="GenericWallpaper" parent="android:Theme.Light"
  item name="android:windowBackground"&gt;@drawable/blackbackground
  item name="android:layout_width"&gt;fill_parent
  item name="android:layout_height"&gt;fill_parent
  </code></pre>
  
  <p>I would rather use my xml style file to specify the icon and title are required than having to set it programatically in the window title bar in every activity.</p>
  
  <p>I am using <code>android:minSdkVersion="8"</code>, <code>android:targetSdkVersion="15"</code></p>
