Cannot import all classes correctly

[sgrumo]

I've tried to clone the project and starting one on my own. I've followed your instruction, but when I finish importing the module of your project it gives me this error:
error: package com.google.vrtoolkit.cardboard does not exist
I've tried to import the modules of googlecardboard as mentioned in Google sample but still gives me the error. How can I do to solve this problem?

It gives me the same error. Cannot import the vr libraries! I don't know why

package com.google.vrtoolkit.cardboard is in cardboard sdk. Do you have the same questions if you import the cardboard sdk for android?

I've imported the sdk through modules. Gave me the error
