Type View requires API level 14 (current min is 4):

<GridLayout
        android:columnCount="4"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/gridContainer"
        android:animateLayoutChanges="true"

        />

When I change android:columnCount="4" to android:columnCount="5" , eclipse show the error "Type View requires API level 14 (current min is 4): <GridLayout>" .

Solution : just clean the project and rebuilt it .
