You can not use ImageSpan in Notification.

If you want to show images, there are two approaches to do it.
1. Custom Notification This is a code snip

      RemoteViews contentViews = new RemoteViews(context.getPackageName(), R.layout.view_notice_common);
        SimpleDateFormat fmt = new SimpleDateFormat("HH:mm");
        contentViews.setTextViewText(R.id.notice_time, fmt.format(Calendar.getInstance().getTime()));
        contentViews.setTextViewText(R.id.notice_title, title);
        contentViews.setTextViewText(R.id.notice_extend_message, content);
        Bitmap smallBitmap = bundle.getParcelable("APP_ICON");
        if (smallBitmap != null) {
            contentViews.setImageViewBitmap(R.id.notice_drawable, smallBitmap);
        } else {
            contentViews.setImageViewResource(R.id.notice_drawable, R.drawable.icon);
        }
        notification.contentView = contentViews;

2. Use Unicode Data
Code snip

  String originalStr = "emoji-" + newString(0x1f602) +newString(0x1f684)+"--over";
  public static final String newString(int codePoint) {
     return new String(Character.toChars(codePoint));
}

Then use originalStr as the Title Text.
