It would have been helpful to have more info here, like logs. In any case, I attempted to reproduce the issue locally. When I run the above steps I see this in my logs:

The important part there is that it's failing to load a native library named libAtalaBar.so I recompiled the platform/android/kfxutilities.jar and see that through chain of calls, we get to com.kofax.kmc.kut.utilities.IpLibutil class, which attempts to load the native libraries: AtalaBar and EvrsJniWrapper. That means there should be an libAtalaBar.so and libEvrsJniWrapper.so somewhere to load. Since this is a JAR file, it isn't inside it. So the basic issue stems from missing native libraries that aren't packaged with this app, but are required by the kfxutilities.jar they're trying to consume. They need to make sure if they have Java libraries that require native libraries that they include those as well (They'd end up at a location like platform/android/libs/<arch>/libAtalaBar.so where arch is x86 or armeabi-v7a). Typically you'd package this up all of this as an AAR so the java code in this jar would be included as well as the native libraries it depends upon and you wouldn't have to worry about copying multiple files/paths over.
