Отправка cookie с помощью http post android

Привет, ребята, я пытаюсь отправить файл cookie с http-сообщением в Android.

вот мой код

webUrl = "XXXXXX";
        webView = (WebView) findViewById(R.id.webview);
        try
        {
            CookieStore cookieStore = new BasicCookieStore();
            Cookie cookie = new BasicClientCookie("session_id", "1234");
            cookieStore.addCookie(cookie);

            DefaultHttpClient httpclient = new DefaultHttpClient();

            BasicHttpContext mHttpContext = new BasicHttpContext();

            mHttpContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);

             HttpGet httpget = new HttpGet("XXXXX");

             HttpResponse response = httpclient.execute(httpget);
             HttpEntity entity = response.getEntity();

             Log.i("TAG", "Login form get: " + response.getStatusLine());
             if (entity != null) {
                 entity.consumeContent();
             }
             Log.i("TAG", "Initial set of cookies:");
             List<Cookie> cookies = httpclient.getCookieStore().getCookies();
             if (cookies.isEmpty()) {
                 Log.i("TAG", "None");
             } else {
                 for (int i = 0; i < cookies.size(); i++) {
                     Log.i("TAG", "- " + cookies.get(i).toString());
                 }
             }

            HttpPost httpost = new HttpPost("XXXXX");

            List <NameValuePair> nvps = new ArrayList <NameValuePair>();
            nvps.add(new BasicNameValuePair("session_id", "1234"));
            nvps.add(new BasicNameValuePair("selected_cid", "1234"));
            nvps.add(new BasicNameValuePair("selected_kaisai_id", "1234"));
            nvps.add(new BasicNameValuePair("iid", "1234"));
            nvps.add(new BasicNameValuePair("tid", "1234"));

            httpost.setEntity(new UrlEncodedFormEntity(nvps));

            response = httpclient.execute(httpost);
            entity = response.getEntity();

            Log.i("TAG", "Login form get: " + response.getStatusLine());
            if (entity != null) {
                entity.consumeContent();
            }

            Log.i("TAG", "Post logon cookies:");
            cookies = httpclient.getCookieStore().getCookies();
            if (cookies.isEmpty()) {
                System.out.println("None");
            } else {
                for (int i = 0; i < cookies.size(); i++) {
                    Log.i("TAG", "- " + cookies.get(i).toString());
                }
            }
            httpclient.getConnectionManager().shutdown();        
        }
        catch(Exception e)
        {
            Log.i("TAG", e.getMessage());
        }
        WebSettings webSettings = webView.getSettings();
        webSettings.setJavaScriptEnabled(true);
        String postData = "session_id=1234";
        webView.postUrl(webUrl, EncodingUtils.getBytes(postData, "BASE64"));

Я могу опубликовать данные из postData, но не файл cookie, файл cookie не отображается в веб-просмотре, вот сторона PHP

public function cookietestAction()
    {
        echo "mixi for netrecorder tester<br/>\n";

        echo "<br/>Cookies...<br/>\n\n";
        $request = new Zend_Controller_Request_Http();
        $sessionid = $request->getCookie('session_id');
        echo "<br/>\nsessionid = ".$sessionid."<br/>\n";

        $selected_cid = $request->getCookie('selected_cid');
        echo "\nselected_cid = ".$selected_cid."<br/>\n";

        $selected_kaisai_id = $request->getCookie('selected_kaisai_id');
        echo "\nselected_kaisai_id = ".$selected_kaisai_id."<br/>\n";

        $iid = $request->getCookie('iid');
        echo "\niid = ".$iid."<br/>\n";

        $tid = $request->getCookie('tid');
        echo "\ntid = ".$tid."<br/>\n";

        if($this->getRequest()->isPost())
        {
            echo "<br/>POST data only...<br/>\n\n";
            $post = $this->getRequest()->getPost('session_id');
            echo "<br/>\nsession_id=".$post."<br/>\n";
            $post = $this->getRequest()->getPost('selected_cid');
            echo "selected_cid=".$post."<br/>\n";
            $post = $this->getRequest()->getPost('selected_kaisai_id');
            echo "selected_kaisai_id=".$post."<br/>\n";
            $post = $this->getRequest()->getPost('tid');
            echo "tid=".$post."<br/>\n";
            $post = $this->getRequest()->getPost('iid');
            echo "iid=".$post."<br/>\n";
        }
}

кто-нибудь может сказать мне, что случилось? благодарю вас
