                public void onClick(View v) {

                    if(checkandRequestPermission()){
                        VCard vCard = Ezvcard.parse(resultText).first();

                        File vcfFile = new File(getActivity().getExternalFilesDir(null), "generated.vcf");

                        try {
                            vCard.write(vcfFile); <<---- error  generated for this line ----- >>
                        } catch (IOException e) {
                            e.printStackTrace();
                        }

                        Intent i = new Intent();
                        i.setAction(android.content.Intent.ACTION_VIEW);
                        i.setDataAndType(Uri.fromFile(vcfFile), "text/x-vcard");
                        startActivity(i);
                    }

Thank you for the report. This is a bug. Fixed in 68278719de4ad6232aa6c4711314a28688244e92.

Work-around:

Use the VCardWriter class instead:

VCard vCard = ...
File vcfFile = ...

VCardWriter writer = null;
try {
  writer = new VCardWriter(vcfFile, vCard.getVersion());
  writer.write(vCard);
} finally {
  if (writer != null) { writer.close(); }
}
