How to set mime type for Android email attachment

Question

I'm sending emails via an Intent. Sometimes they need to have an attachment, but the attachment gets the same MIME type as the main email (message/rf822).

Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_EMAIL, new String[] { address });
intent.putExtra(Intent.EXTRA_TEXT, body);
intent.putExtra(Intent.EXTRA_SUBJECT, subject);
if (fileName != null) {
    intent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://" + fileName));
}
intent.setType("message/rfc822");

Is there a way to specify the MIME type for the attachment ?
