                val document = Document(pdfDocument, PageSize.A4)


                document.add(Paragraph(line1).setFont(myFont))
                document.add(Paragraph(line2).setFont(myFont))

but I got below error :

I stil try to context.assets.open("fonts/yekanbakh.ttf").readBytes().

but I failed and got same error ... the full code is :

        val myFile = File(dir, "$name.pdf")

        try {
            val fileOutputStream = FileOutputStream(myFile)
            val pdfWriter = PdfWriter(fileOutputStream)
            val pdfDocument = PdfDocument(pdfWriter)

            val typeface = ResourcesCompat.getFont(requireContext(),R.font.yekanbakh)
            val context = requireContext()

                document.add(Paragraph(line1).setFont(myFont))
                document.add(Paragraph(line2).setFont(myFont))


                val table1 = Table(subHeaders1.size)
                    .useAllAvailableWidth()
                    .setFontSize(10f)

                subHeaders1.forEach { col ->
                    table1.addHeaderCell(col)
                }
                body1.forEach { row ->
                    row.forEach { col ->
                        table1.addCell(col.toString())
                    }
                }
                document.add(table1)


                val table2 = Table(subHeaders2.size)
                    .useAllAvailableWidth()
                    .setFontSize(10f)

                    table2.addHeaderCell(col.toString())
                }
                body2.forEach { row ->
                    row.forEach { col ->
                        table2.addCell(col.toString())
                    }
                }
                document.add(table2)


                val table3 = Table(subHeaders3.size)
                    .useAllAvailableWidth()
                    .setFontSize(10f)

                subHeaders3.forEach { col ->
                    table3.addHeaderCell(col)

                        table3.addCell(col.toString())
                    }
                }
                document.add(table3)

                document.add(Paragraph(line3))

                document.close()
                fileOutputStream.close()

Answer 1

Your code is correct, you have fonts in wrong directory, you have to put it in assets directory. AssetsManager from context is working with assets directory, not the res.

With Android studio create assets folder like this: File -> New -> Folder -> Assets Folder, and put your font in it. It should look like in the picture:

Directory font is used for defining fonts your app will use for showing text, you can't load font as byte array from there.
