Fann library integration in android studio, where to find libfann.so files?

Question

Java

I'm trying to integrate the fann library into android studio, but everything is even.
In my project I also use libgdx and because of it I have files:

• arm64-v8a
  
• armeabi
  
• armeabi-v7a
  
• x86
  
• x86-64
  

In all these files I have: libjnidispath.so - this file for each of the folders. When I run the project, it crashes with an error - java.lang.UnsatisfiedLinkError: Unable to load library 'fann': Native library (android-arm/libfann.so) not found in resource path (.)
Also in gradle I have 2 more lines in the file:

• implementation group: 'net.java.dev.jna', name: 'jna', version: '4.5.0'
  
• implementation group: 'com.googlecode.fannj', name: 'fannj', version: '0.6'
  

Where can I get these files? Already climbed a bunch of forums, was on their official website, but did not find anything about these files

Answer 1

The fact is that jna and fannj are just wrappers. You will have to cross-compile the library itself. You can see an example for dlib .
