It appears the AIR SDK has support for this in the form of https://bdsc.webapps.blackberry.com/air/apis/qnx/s
It's possible this one isn't exposed directly in the NDK yet. There is a PPS object (user_activity) we could monitor, and that's probably the same one the AIR runtime is watching. It's best to avoid direct access to those, however, as they could change in any release and you don't generally want to couple your app to them tightly...
Best is if there is or will be an NDK API to match the one AIR has.
