    In the onCreate method your application file. Place the following code

    StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());

    This will make the exception go away. However, this is used mostly as a diagnostic tool and it not a proper solution.

    Another solution with the fileProvider method would be to add FLAG_GRANT_READ_URI_PERMISSION flag to your intent.

    Intent intent = new Intent(Intent.ACTION_VIEW, FileProvider.getUriForFile(this, AUTHORITY, f));
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);

    Try below code it works for sharing VCFile:

     private void shareContact(ContactsModal modal) {

    String lookupKey = null;
    Cursor cur = ((Activity)context).getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, new String[]
            { ContactsContract.Contacts.LOOKUP_KEY },
            ContactsContract.Contacts._ID + " = " + modal.getContactID(), null, null);

    if (cur.moveToFirst()) {
         lookupKey = cur.getString(0);
    }
    if(lookupKey!=null){
        Uri vcardUri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_VCARD_URI, lookupKey);
        Intent intent = new Intent(Intent.ACTION_SEND);
        intent.setType(ContactsContract.Contacts.CONTENT_VCARD_TYPE);
        intent.putExtra(Intent.EXTRA_STREAM, vcardUri);
        intent.putExtra(Intent.EXTRA_SUBJECT, "Contact Name");
        ((Activity)context).startActivity(intent);
    }
}
