Android dashboard pattern as fragment

Question

Is is possible to use the android dashboard pattern from Google I/O as a fragment so that in landscape mode on a tablet the dashboard is shown on the left while the content of the current category is shown on the right?

I've tried something that looks like the code below but it doesnt work.

main.xml:

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- Include dashboard -->
    <include layout="@layout/fragment_dashboard"/>

    <!-- Include details -->
    <fragment
        android:id="@+id/fragment_details"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.example.fragments.Details" />
</LinearLayout>

Details.java:

public class Details extends Fragment
{

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                        Bundle savedInstanceState)
        {
                View view = inflater.inflate(R.layout.details, container, false);

                return view;
        }

}
