UE4.11.1 Android build - Failed to load VrApi driver

As I know Oculus mobile sdk 1.0.0 is included into UE4.11 and there isn’t way to install or change it separately from engine. There must be some kind of emulator of Gear vr or something like that, because in android manifest I see permission for gyro sensors and other sruff. Also I see a lot of UE VR apps in play market for google CB and I’m sure that they didn’t make their own emulator.

Or can you suggest any way to start using UE under google cardboard?
