The currentValue variable doesn't use InputOverlay.OVERLAY_
constants, it uses NativeLibrary.ButtonType constants.
Sigh, why do enums have to be so bad on Android that Google
recommends against using them :(
Anyway, simply not doing anything is a reasonable option here.
What happens then is that if the currently selected button is
invalid for the current controller, none of the available options
in the dialog will be pre-selected.
