title: Error adding custom theme to app
body: <p>I added the following theme to my app with a background color of white.But I get the following  error and I'm not sure where I have gone wrong.</p>
  
  <p><code>Error: Color types not allowed (at 'android:windowBackground' with value '#FF0000')</code>.</p>
  
  <pre><code>&lt;style name="MyTheme" parent="@android:style/Theme.Light"&gt; 
    &lt;item name="android:windowBackground"&gt;#FF0000&lt;/item&gt;
   &lt;/style&gt;
  </code></pre>
  
  <p>And referenced the theme in mymanifest:</p>
  
  <pre><code>&lt;activity
          android:name=".MyActivity"
          android:theme="@style/MyTheme" /&gt;
  </code></pre>
  
  <p>Any ideas or suggestions? Thanks</p>
