Hi, my name's Davide. I'm having some difficulty in testing the package provided through this support. In the ScanActivity.java I get this error:

E/AndroidRuntime: FATAL EXCEPTION: main

Point by point the line reported by Android studio is this:
System.loadLibrary("opencv_java3");

would you have an idea on how to solve?
