Easy AR 3.1 open camera failed on Android 5.1 device Unity 2017.4 & 2018.2.19 & 2018.4.5

Question

The app works fine with Easy AR 2.3 but I want to get 64 bit.  I've tried building with easy AR 3.0 and 3.1  both get same error

 I/Unity   (24884): [EasyAR] use ezar camera device
I/Unity   (24884):
I/Unity   (24884): (Filename: /Users/builduser/buildslave/unity/build/artifacts/generated/Android/runtime/DebugBindings.gen.cpp Line: 51)
I/Unity   (24884):
I/Unity   (24884): [EasyAR] open camera failed
I/Unity   (24884):
I/Unity   (24884): (Filename: /Users/builduser/buildslave/unity/build/artifacts/generated/Android/runtime/DebugBindings.gen.cpp Line: 51)

Also tried to use the custom camera option but opening of camera still fails.  The result is that the app is up and running but camera never opens.  Any advice would be greatly appreciated.  Thanks for your time.

What's your Android device? Are you using a built-in camera or a USB camera?
