ошибка во время выполнения с активностью фрагмента

Question

Я пытаюсь воссоздать пример FragmentPagerSupport , но получаю сообщение об ошибке и не знаю, о чем он просит.

это делает

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.fragment_pager_list, container, false);
        View tv = v.findViewById(R.id.text);
        ((TextView)tv).setText("Fragment #" + mNum);
        return v;
    }

затем выдает ошибку времени выполнения

это я. Фрагмент_пейджер

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" 
android:id="@+id/layout">

<TextView
    android:id="@+id/text"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="60dp"
    android:text="Large Text"
    android:textAppearance="?android:attr/textAppearanceLarge" />



<ListView
    android:id="@+id/list"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/text"
    android:layout_centerHorizontal="true" >

</ListView>

</RelativeLayout>

а это мой главный

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<android.support.v4.view.ViewPager
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:id="@+id/pager"/>
</LinearLayout>

ошибка
