By "not readily" he means that there is no nice public API for "what application has focus", but things that look close (e.g. RunningAppProcessInfo importance sounds close, but requires polling, is slow to update, and refers to scheduler time, not what the user is doing.) If you want to play non public API games pre-JellyBean you could watch for ActivityManager messages for application start (JellyBean restricts the Log output so you need to be a system app to see it.)
The Google company line for not providing such an API seems to range from privacy to performance. The net result is that if the performance monitoring tools provided (stuff under Settings or dumpsys) don't match your needs precisely, tough luck, you don't get to harness the app developers out there to create something beyond what Google provides. Unless your company has some bizarre change request process, you'll be much happier having activity A do some IPC you can count on.
