Crashes when app runs in android devices

I am currently using vuforia 6.2 and Google VR 1.20 at the same time on Unity 5.5.1

They work fine when working through a Unity however, 

when I build and run on android devices, it crashes after the unity logo with saying the app has stopped.

We tested on several devices, samsung note3, Galaxy 4s and Galaxy 6s. 

version for note 3 is 4.4.2, 4s is 5.0.1 and 6s is 6.0.1.

None of these works.

I have uploaded the log file below.

 

Thank you
