You can use this:

String getMetaTag(Document document, String attr) {
    Elements elements = document.select("meta[name=" + attr + "]");
    for (Element element : elements) {
        final String s = element.attr("content");
        if (s != null) return s;
    }
    elements = document.select("meta[property=" + attr + "]");
    for (Element element : elements) {
        final String s = element.attr("content");
        if (s != null) return s;
    }
    return null;
}

Then:

 String title = document.title();
 String description = getMetaTag(document, "description");
 if (description == null) {
    description = getMetaTag(document, "og:description");
 }
 // and others you need to
 String ogImage = getMetaTag(document, "og:image")
