Android : Copy cookie from WebView to HttpUrlOpenConnection

I want to copy cookie which I recived in WEbView and then use them in my urlopenconnections.

By default I use

CookieManager cookieManager = new CookieManager();
        CookieHandler.setDefault(cookieManager);

And it works perfectly to handle cookies in my HttpUrlOpenConnection requests. However, somehow it does not attach cookes from webview to my requests. I tried

mWebView.setWebViewClient(new WebViewClient() {
            @Override
            public void onPageFinished(WebView view, String url) {
                String cookies = android.webkit.CookieManager.getInstance()
                        .getCookie(url);
                HttpCookie cookie = new HttpCookie(url, cookies);
                URI uri = null;
                try {
                    uri = new URI(url);
                } catch (URISyntaxException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                CookieManager c = new CookieManager();
                c.getCookieStore().add(uri, cookie);
                Log.d("cookie check", "All the cookies in a string:" + cookies);
                // CookieManager cookieManager = new CookieManager();
                CookieHandler.setDefault(с);
            }
}

But did not succed. How can I attack cookies from webview to my requests?
