The problem I am running into is, when implementing the card.io library, it was adding the opencv library to my apk 2x as I am already using the opencv library. I updated my build.gradle to resolved that issue:
packagingOptions {
pickFirst 'lib/x86/libopencv_core.so'
pickFirst 'lib/x86/libopencv_imgproc.so'
}
Now when I run my app and open the card.io Activity I get the following in my logcat:
I/card.io: card.io 5.5.0 01/26/2017 16:20:26 -0500
D/card.io: Loaded card.io decider library.

I/card.io: Processor not Supported. Skipping camera.
Also, if I remove my implementation of openCV and my manifest changes the card.io works as expected, what am I missing??
I am running this in emulator but have tested the same outcome occurs on a real device.
Any help is greatly appreciated!
UPDATE After some searching, It seems that card.io is using openCV version 2.4.13-0
So I attempted to change the openCV version I am using, which started the card.io camera functions working again, but that is causing another error in my project.

So from what I take it is looking for 'libjniopencv_core.so' is that something that is not in this older version? I was using version: 3.1.0-1.3
I am not farmiliar with OpenCV so I'm not sure if there is something in the code specifically loading this file, a freelancer did our OpenCV work a long while back. Any help or input is appreciated!
To fix this I had to get a java developer better than myself to compile card.io using the later 3.1.0-1.3 version of openCV.
