DatePicker android:calendarViewShown

Question

I've the following code:

<DatePicker
    android:id="@+id/datepicker"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:calendarViewShown="true" />

But the attribute android:calendarViewShown is not working. Why?
It's in the Android Developer's Guide.

Answer 1

That's only available for API 11 and higher. Are you targeting a lower one?
