Checkbox always unchecked (no matter what is the default value)
<p>Here i have my preferences in xml folder. No matter what I set as "defaultValue" I always get visually unchecked box, when I open my preference activity. Is this some kind of bug? </p>

<pre><code>&lt;PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" &gt;

  &lt;CheckBoxPreference 
     android:title="Enabled" 
     android:defaultValue="true" 
     android:key="checkbox_enabled_disabled"/&gt;   

&lt;/PreferenceScreen&gt;
</code></pre>
