Android HttpClient and Cookies

Question

I have a problem with the HttpClient in Android: By using the following code, I want to use the cookies which are already set before by logging in through a webview. So the login data should be there and is indeed there, I tested it. But when I use the cookies in an httppost or httpget it doesn't use the login data. but these cookies actually should be enough to receive that page for which a login is necessary, shouldn't they? I'm not really sure if I need to send the cookies in a special way to the server or so or if it is enough to load it into the httpcontext. Here is the code:

DefaultHttpClient httpclient = new DefaultHttpClient();
CookieStore lCS = new BasicCookieStore();


if (CookieManager.getInstance().getCookie(pUrl) != null) {  
    String cookieString = CookieManager.getInstance().getCookie(pUrl);

    String[] urlCookieArray = cookieString.split(";");
    for (int i = 0; i < urlCookieArray.length; i++) {           
        System.out.println(urlCookieArray[i]);          
        String[] singleCookie = urlCookieArray[i].split("=");
        Cookie urlCookie = new BasicClientCookie(singleCookie[0], singleCookie[1]);
        lCS.addCookie(urlCookie);           
    }

}

HttpContext localContext = new BasicHttpContext();
httpclient.setCookieStore(lCS);
localContext.setAttribute(ClientContext.COOKIE_STORE, lCS);

HttpPost httppost = new HttpPost(pUrl);        


    // get the url connection       
try {

    StringBuilder sb = new StringBuilder();     
    HttpResponse response = httpclient.execute(httppost, localContext);     
    InputStream is = response.getEntity().getContent();         
    InputStreamReader isr = new InputStreamReader(is);          

And if I run the code I only receive the login page of that site, so it didn't accept the cookie.

Thanks for help in advance

I had the same problem and I used similar approach as in the question with no luck. The thing that made it work for me was to add the domain for each copied cookie. (BasicClientCookie cookie.setDomain(String))

My util function:

public static BasicCookieStore getCookieStore(String cookies, String domain) {
    String[] cookieValues = cookies.split(";");
    BasicCookieStore cs = new BasicCookieStore();

    BasicClientCookie cookie;
    for (int i = 0; i < cookieValues.length; i++) {
        String[] split = cookieValues[i].split("=");
        if (split.length == 2)
            cookie = new BasicClientCookie(split[0], split[1]);
        else
            cookie = new BasicClientCookie(split[0], null);

        cookie.setDomain(domain);
        cs.addCookie(cookie);
    }
    return cs;
}

 String cookies = CookieManager.getInstance().getCookie(url);
 BasicCookieStore lCS = getCookieStore(cookies, MyApp.sDomain);

 HttpContext localContext = new BasicHttpContext();
 DefaultHttpClient httpclient = new DefaultHttpClient();
 httpclient.setCookieStore(lCS);
 localContext.setAttribute(ClientContext.COOKIE_STORE, lCS);
