Retaining AIR functionality in Flash Player (3D)

I have to target Flash Player 11 for 3D projects, which means I'm struggling to retain some important AIR functionality for Android:

NativeApplication.nativeApplication.systemIdleMode = SystemIdleMode.KEEP_AWAKE;

NativeApplication.nativeApplication.addEventListener(Event.DEACTIVATE, DeactivateDevice);

NativeApplication.nativeApplication.addEventListener(Event.ACTIVATE, ReactivateDevice);

I get the error:

1120: Access of undefined property NativeApplication.

Or this if I try to import the class manually:

1172: Definition flash.desktop:NativeApplication could not be found.

Is it possible to have the best of both worlds? And if not, how can I achieve the above things some other way?
