The preference_headers resource describes the displayed headers and their associated snippets. It:

<header android:fragment="com.example.android.apis.preference.PreferenceWithHeaders$Prefs1Fragment"
        android:icon="@drawable/ic_settings_applications"
        android:title="Prefs 1"
        android:summary="An example of some preferences." />

<header android:fragment="com.example.android.apis.preference.PreferenceWithHeaders$Prefs2Fragment"
        android:icon="@drawable/ic_settings_display"
        android:title="Prefs 2"
        android:summary="Some other preferences you can see.">
    <!-- Arbitrary key/value pairs can be included with a header as
         arguments to its fragment. -->
    <extra android:name="someKey" android:value="someHeaderValue" />
</header>

<header android:icon="@drawable/ic_settings_display"
        android:title="Intent"
        android:summary="Launches an Intent.">
    <intent android:action="android.intent.action.VIEW"

</header>
