Answer 1

How about this? Below statement parse all tags start with "og:". It's useful.

doc.select("meta[property^=og:]")

void parseOGTag(String response) {
    // Parse og tags
    Document doc = Jsoup.parse(response);
    Elements ogTags = doc.select("meta[property^=og:]");
    if (ogTags.size() <= 0) {
        return;
    }

    // Set OGTags you want
    String title;
    String desc;
    String image;
    for (int i = 0; i < ogTags.size(); i++) {
        Element tag = ogTags.get(i);

        String text = tag.attr("property");
        if ("og:image".equals(text)) {
            image = tag.attr("content");
        } else if ("og:description".equals(text)) {
            desc = tag.attr("content");
        } else if ("og:title".equals(text)) {
            title = tag.attr("content");
        }
    }                    
}
