UnsatisfiedLinkError with PDFium on Android 15 Emulator with 16 KB Page Size

[yd-threra-and]

Environment

• Library version: 3.2.0-beta.1
• Android version: 15 (Vanilla Ice Cream)
• Emulator: 16 KB page size

Steps to Reproduce

1. Create an Android emulator with 16 KB page size following the steps in the Android Developers Guide.
2. Use the PDF Viewer library to load a PDF document with the following code from some fragment from our demo test app:

   override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
       super.onViewCreated(view, savedInstanceState)
       val outputFile = File(requireContext().filesDir, "sample.pdf")
       if (!outputFile.exists()) {
           try {
               val inputStream: InputStream = requireContext().assets.open("sample.pdf")
               val outputStream = FileOutputStream(outputFile)
               val buffer = ByteArray(1024)
               var length: Int
               while (inputStream.read(buffer).also { length = it } > 0) {
                   outputStream.write(buffer, 0, length)
               }
               outputStream.close()
               inputStream.close()
           } catch (e: IOException) {
               e.printStackTrace()
           }
       }
   
       binding.pdfView.fromFile(outputFile)
           .enableSwipe(true)
           .swipeHorizontal(false)
           .enableDoubletap(true)
           .defaultPage(0)
           .onLoad { nbPages -> /* Do something on load complete */ }
           .onPageError { page, t -> /* Handle page error */ }
           .load()
   }

3. Observe the error.
