Question

I am almost dead doing this.Need help.

My Requirement :-

What I tried :-

For this I tried HttpClient and HttpURLConnection referring many SO questions but failed.

Can anybody please give me a sample code?

Say I have cookies in a hashmap cookies. How Can I use HttpClient and HttpURLConnection or anything else to get the other page html. The website I am trying with is https:

Please give a sample code

Are you able to read the Cookie with the session-id by JavaScript in your WebView? By default these Session-Cookies are marked "HttpOnly" when created server-side, so it should not be possible to get the values by script. Try to execute `console.log(document.cookie)` in your WebView and watch LogCat. Can you see the SessionId? — hgoebl, Jan 10 '14 at 15:00
@hgoebl we can get the httponly cookies also by CookieManager.getInstance().getCookie("url") — user, Jan 10 '14 at 15:45
So where is the problem? Take the cookie and [set the header](http://en.wikipedia.org/wiki/HTTP_cookie#Setting_a_cookie). — hgoebl, Jan 10 '14 at 16:54

If I am right u are trying to use your webview's cookies to get other pages of site in your activity java code.if yes try this:

BufferedReader reader = null;
try {
    URL url2 = new URL("url");
    URLConnection con = (URLConnection) url2.openConnection();
    CookieManager.getInstance().setAcceptCookie(true);

    con.setRequestProperty("Cookie",CookieManager.getInstance().getCookie("logged in url in webview"));
    con.setDoOutput(true);
    con.connect();

    reader = new BufferedReader(new InputStreamReader(con.getInputStream()));
    StringBiffer html;
    String line = "";
    while ((line = reader.readLine()) != null) {
        html.append(line);
    }
} catch (Exception e) {
    e.printStackTrace();
}

It worked for me.

Have you tried to add the cookie as a HTTP header? I am not sure if I have understood you right but you can consider these:

Cookies: If you want to load some resource (no matter if it is a web page, image, css, js or something else) you are making a HTTP request. If the server keeps a session for your user, you are probably given a session cookie. The cookie must be sent with each request to the server as e COOKIE header. So if you want to pass the cookie to your request, add it as a header. Android provides you an easy way to do this with the CookieManager class. You can refer to this.
SSL: If you are trying to access a secured web site (https) you have to use an SSL certificate. Android comes up with a bunch of predistributed certificates for most of the popular web cites (e.g Facebook, Google, Twitter, etc.). You can use them out of the box. If your SSL certificate is not presented, you have to add it manually. Read this for more information.

I hope this was useful :)
