Adding compatibility note for drag/drop in N. am: 06b9b60c

         * {@link android.widget.LinearLayout.LayoutParams LinearLayout.LayoutParams} to

         * {@link android.widget.RelativeLayout.LayoutParams RelativeLayout.LayoutParams}).</li>

         * <li>Your application processes will not be killed when the device density changes.</li>

         * <li>Drag and drop. After a view receives the

         * {@link android.view.DragEvent#ACTION_DRAG_ENTERED} event, when the drag shadow moves into

         * a descendant view that can accept the data, the view receives the

         * {@link android.view.DragEvent#ACTION_DRAG_EXITED} event and won’t receive

         * {@link android.view.DragEvent#ACTION_DRAG_LOCATION} and

         * {@link android.view.DragEvent#ACTION_DROP} events while the drag shadow is within that

         * descendant view, even if the descendant view returns <code>false</code> from its handler

         * for these events.</li>

         * </ul>
