Note that this only works with applications that want to participate in the mechanism, and pretty much none of the built-in applications do this. We moved away from this approach because managing the UI for an arbitrary number of additional items is a challenge. Our preference these days is for the application to start a chooser activity from which the user can select what they want to do; see the Intent docs for info on this.
