Cardboard application shows a blue screen when launched in an android mobile


I’m a newbie cardboard developer. I’m working on a cardboard experience for android using unity 5.5.0f3 however, I’m facing a major problem. Every time I launch the application in any mobile phone all it shows is a blue screen.The application is working fine in the unity editor. I’m using Google SDK version 0.7 and building for Android 2.3.1 ‘Gingerbread’ API level 9. Any help will be greatly appreciated.

Thank you.

I have resolved my issue for Google cardboard by these steps.

Edit -> Project settings -> Player -> Other settings -> Graphics APi

And remove Vulkan from the list by clicking - at the right bottom.
