How to BACK from second screen to first screen when device rotate 90 degree in android cardboard?

Question

I am trying to develop an sample cardboard app in android. In that I am switching from First screen to Second screen, and i have done that successfully .

But when i am trying to BACK from second screen to first screen i don't know how to do that. I have gone through some of the links but didn't get success.

Actually, you don't need two screens , you need to update the layout when you rotate your screen .use two xml layout for the same activity. you need to handle screen change in onConfigurationChanged method.here is a full explanation on how to achieve it http://www.codeproject.com/Articles/422431/Handling-screen-layout-changes-in-Android
