* This class is a view for choosing an activity for handling a given {@link Intent}.
*
* The view is composed of two adjacent buttons:
*
* -
* The left button is an immediate action and allows one click activity choosing.
* Tapping this button immediately executes the intent without requiring any further
* user input. Long press on this button shows a popup for changing the default
* activity.
*
* -
* The right button is an overflow action and provides an optimized menu
* of additional activities. Tapping this button shows a popup anchored to this
* view, listing the most frequently used activities. This list is initially
* limited to a small number of items in frequency used order. The last item,
* "Show all..." serves as an affordance to display all available activities.
