App doesn't work when published

I have a very basic vr app using Google cardboard sdk. It simply looks at a model like the one in the Cardboard App. And recognises magnet pull and screen touch to set of an animation. I build and run the app onto my android device and it works exactly how it should with no flaw when I then publish that apk file onto the play store and download that app and open it. The splash screen appears then I see the Google cardboard settings button and back button on a fully black screen. Urgently need some help.
Thanks all

 

Make sure split application binary is unselected under publishing settings
