Answer 1

To get all links/URLs from your webView, you need a html parser to iterate the page content. Then, you can loop the result list and check if it contains your Youtube Channel url or the url that you are looking for.

1) You can use jsoup, this is an example (taken from here ):

File input = new File("/tmp/input.html");
Document doc = Jsoup.parse(input, "UTF-8", "http://example.com/");

Elements links = doc.select("a[href]"); // get all "a" elements with "href"
Elements pngs = doc.select("img[src$=.png]");// get all "img" with src ending .png

Element masthead = doc.select("div.masthead").first();

2) OR use HTML Parser library.

public static List getLinksOnPage(final String url) {
    final Parser htmlParser = new Parser(url);
    final List result = new LinkedList();

    try {
        final NodeList tagNodeList = htmlParser.extractAllNodesThatMatch(new NodeClassFilter(LinkTag.class));
        for (int j = 0; j < tagNodeList.size(); j++) {
            final LinkTag loopLink = (LinkTag) tagNodeList.elementAt(j);
            final String loopLinkStr = loopLink.getLink();
            result.add(loopLinkStr);
        }
    } catch (ParserException e) {
        e.printStackTrace(); // TODO handle error
    }

    return result;
}

3) OR create your own parser, something like:

String HTMLPage; // get the HTML page as a String
Pattern linkPattern = Pattern.compile("(]+>.+?)",  Pattern.CASE_INSENSITIVE|Pattern.DOTALL);
Matcher pageMatcher = linkPattern.matcher(HTMLPage);
ArrayList links = new ArrayList();
while(pageMatcher.find()){
    links.add(pageMatcher.group());
}

links ArrayList will contains all links in the page.

PS: You can edit linkPattern to filter some links.
