WhatsApp format of vcard is not supported?

[rohaitas]

What am i missing? I am able to add contact as a file. But not in sender intent

` VCard vcard = new VCard();
String fileName = "null";
String num = getRawNUmber(item);
if (num != null) {
vcard.addTelephoneNumber(num, TelephoneType.CELL);
}
fileName = item.getDisplayNamePrimary();
vcard.setFormattedName(item.getDisplayNamePrimary());

    vcard.setKind(Kind.individual());
    vcard.setGender(Gender.male());
    vcard.addLanguage("en-US");

    StructuredName n = new StructuredName();
    n.setFamily("Doe");
    n.setGiven("Jonathan");
    n.getPrefixes().add("Mr");
    vcard.setStructuredName(n);

    vcard.setRevision(Revision.now());
    vcard.validate(VCardVersion.V4_0);

    File files = new File(context.getFilesDir(), fileName + ".vcf");

    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {

        try {
            files.createNewFile();
            Path file = Paths.get(files.getAbsolutePath());
            Ezvcard.write(vcard).version(VCardVersion.V4_0).go(file);
            Uri fileUri = FileProvider.getUriForFile(context, context.getPackageName() + ".provider", files);
            Intent shareIntent = new Intent(Intent.ACTION_SEND);
            shareIntent.setType("text/vcard");
            shareIntent.putExtra(Intent.EXTRA_STREAM, fileUri);
            shareIntent.putExtra(Intent.EXTRA_SUBJECT, "Share Contact");
            shareIntent.putExtra(Intent.EXTRA_TEXT, "Here's a contact.");
            context.startActivity(Intent.createChooser(shareIntent, "Share contact using..."));

        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }`
