my android kotlin activity is not finding libhunspell.so

Question

I want to write a activity for my android app that spell-checks words in my language (Czech). I included the .dic and .aff that I need. The app runs normally but when I try to proceed to this activity

package com.example.mainscreen

import android.content.ClipData
import android.content.ClipboardManager
import android.content.Context
import android.content.Intent
import android.os.Bundle
import android.widget.Button
import android.widget.ImageView
import android.widget.TextView
import android.widget.Toast
import androidx.appcompat.app.AppCompatActivity
import androidx.core.content.ContextCompat.getSystemService
import androidx.core.content.ContextCompat.startActivity
import com.nikialeksey.hunspell.Hunspell
import com.sun.jna.Native
import com.sun.jna.NativeLibrary

    class TextCheck : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_text_check)
        val incorrectText = findViewById<TextView>(R.id.incorrectText)
        val correctText = findViewById<TextView>(R.id.suggText)
        val copyBtn = findViewById<ImageView>(R.id.copyicon)
        val backBtn = findViewById<Button>(R.id.backBtn)

        val resultTV = intent.getStringExtra("resultTV")

        incorrectText.text = resultTV


        val libPath = "MainScreen\\app\\libs\\hunspell.jar"

        val hunspell = Hunspell("resources/dictionaries/cs_CZ.dic", "resources/dictionaries/cs_CZ.aff")
        NativeLibrary.addSearchPath("hunspell", libPath)

        val misspelledWords = mutableMapOf<String, List<String>>()

        resultTV?.split(" ")?.forEach { word ->
            if (hunspell.spell(word)) {
                misspelledWords[word] = hunspell.suggest(word)
            }
        }

        if (misspelledWords.isNotEmpty()) {
            val correctedText = StringBuilder()
            misspelledWords.forEach { (misspelled, suggestions) ->
                correctedText.append("$misspelled: ${suggestions.joinToString(", ")}")
                correctedText.append("\n")
            }
            correctText.text = correctedText.toString()
        } else {
            correctText.text = getString(R.string.textright)
        }

        copyBtn.setOnClickListener {
            val clipboard = getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
            val clip = ClipData.newPlainText("corrected text", correctText.text)
            clipboard.setPrimaryClip(clip)
            Toast.makeText(this, "Corrected text copied to clipboard", Toast.LENGTH_SHORT).show()
        }


        backBtn.setOnClickListener {
            val intent = Intent(this, MainActivity::class.java)
            startActivity(intent)
        }


    }



    }

it returns to main page and giving me this error
