UnsatisfiedLinkError library open failed

I have imported one sample OpenCv Facerecognition project from https://github.com/ayuso2013/face-recognition, This code works perfectly on Lollipop and Marshmallow devices.

When I run the same project on Nougat devices I am getting following crash report.

So I have tried copy paste armeabi-v7a jniLibs folder and rename it as arm64-v8a and now I am getting java.lang.UnsatisfiedLinkError: dlopen failed: “/data/app/org.opencv.javacv.facerecognition-2/lib/arm64/libopencv_java.so” is 32-bit instead of 64-bit

So how can I overcome these issues?
Where can I get 64 bit native files for these 32 bit files?
or else can I force the system to use only 32 bit files in 64 bit system also?
If yes how can I force?

Actually I want working sample of opencv facerecognition project on both 64bit and 32bit systems.

I have searched lot and finally I am helpless. Any help will be highly motivated to me.
