- Mark the chooser activity as never launching in to a new task, even if the caller asks for it. These are dialogs so don't make sense as stand-alone tasks. (Maybe later the policy should be to not launch into a new task in any case that the activity is a dialog or even transparent at all.) - Keep track in the task record of whether any activities in it have been shown to the user, and use this to automatically remove the task when all activities finish. This leans up cases where apps are launching stub activities that get turned in to tasks but are never seen by the user because they immediately launch another activity in another task and then finish.
