how to quit instead of suspend on Android?

http://qt-project.org – For various reasons, I’d really like to just quit my Android app instead of being suspended. I’ve tried grabbing the applicationStateChanged() signal and calling QGuiApplication->quit(), but that seems not to work. I’ve also tried to accomplish this by setting the android:noHistory property on the activity, to no discernible effect. Any ideas? (HowTos)
