这个是自己总结出来的经验，用户名密码登录验证后保存Session

// 你的URL
                HttpPost httppost = new HttpPost(Constants.ServerUrl.WEB_URL + url);
                try {
 
                        List nameValuePairs = new ArrayList(2);
 
                        // Your DATA
                        nameValuePairs.add(new BasicNameValuePair("UserName", map
                                        .get("UserName")));
 
                        nameValuePairs.add(new BasicNameValuePair("Password", map
                                        .get("Password")));
 
                        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
 
                        HttpResponse response;
 
                        response = httpclient.execute(httppost);
                        if (response.getStatusLine().getStatusCode() == 200) {
                                // 获得响应
                                String result = EntityUtils.toString(response.getEntity());
                                // SharedPreferences preferences = context.getSharedPreferences(
                                // "login", Context.MODE_PRIVATE);
                                // Editor editor = preferences.edit();
                                // String handlers = "";
                                String cookie = "";
                                Date sessionTime = new Date();
                                List cookies = httpclient.getCookieStore().getCookies();
                                if (!cookies.isEmpty()) {
                                        for (int i = 0; i < cookies.size(); i++) {
                                                cookie = cookies.get(i).getName() + "="
                                                                + cookies.get(i).getValue() + ";domain="
                                                                + cookies.get(i).getDomain();
                                                ;
                                                sessionTime = cookies.get(i).getExpiryDate();
                                        }
                                }
                               //保存session
                                PersistentConfig config = new PersistentConfig(context);
                                config.setCookie(cookie);
 
                                config.setSessionTime(sessionTime.getTime());
                                // for (int i = 0; i < response.getAllHeaders().length; i++) {
                                // if (response.getAllHeaders().toString().contains(
                                // "set-cookie")) {
                                // handlers += response.getAllHeaders().toString();

                                // }
                                // }
                                //

                                // editor.commit();
                                return result;
                        }
 
                } catch (ClientProtocolException e) {
 
                        // TODO Auto-generated catch block
 
                        e.printStackTrace();
 
                } catch (IOException e) {
 
                        // TODO Auto-generated catch block

如何在Webview请求网站时使用Session

        //webview初始化的时候调用
        main_view = (WebView) findViewById(R.id.main_webview);
        new WebViewTask().execute();
         
        private class WebViewTask extends AsyncTask {
                String sessionCookie;
                CookieManager cookieManager;
 
                @Override
                protected void onPreExecute() {
                        CookieSyncManager.createInstance(MainActivity.this);
                        cookieManager = CookieManager.getInstance();
 
                        sessionCookie = new PersistentConfig(getApplicationContext())
                                        .getCookieString();
                        if (sessionCookie != null) {
                                // delete old cookies
                                cookieManager.removeSessionCookie();
                        }
                        super.onPreExecute();
                }
 
                protected Boolean doInBackground(Void... param) {
                        // this is very important - THIS IS THE HACK
                        SystemClock.sleep(1000);
                        return false;
                }
 
                @Override
                protected void onPostExecute(Boolean result) {
                        if (sessionCookie != null) {
                                cookieManager.setCookie(Constants.ServerUrl.WEB_URL,
                                                sessionCookie);
                                CookieSyncManager.getInstance().sync();
                        }
                        main_view.setScrollbarFadingEnabled(true);
                        main_view.getSettings().setPluginsEnabled(true);
                        main_view.getSettings().setPluginState(PluginState.ON);
                        main_view.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
                        WebSettings webSettings = main_view.getSettings();
                        webSettings.setJavaScriptEnabled(true);
                        // 设置可以访问文件
                        webSettings.setAllowFileAccess(true);
                        // 设置支持缩放
                        webSettings.setBuiltInZoomControls(true);
                        main_view.setWebViewClient(new WebViewClient() {
                                @Override
                                public void onPageStarted(WebView view, String url,
                                                Bitmap favicon) {
                                        // TODO Auto-generated method stub 
                                        super.onPageStarted(view, url, favicon);
                                }
 
                                @Override
                                public void onLoadResource(WebView view, String url) {
                                        // history(); 
                                }
                        });
                        main_view.setWebChromeClient(new WebChromeClient() {
                                public void onProgressChanged(WebView view, int progress) {
                                        //Change
                                }
                        });
                        ShowUrlView(Constants.ServerUrl.INDEX);
                }
        }

这样就可以每次刷新页面的时候带着session一起请求

如果想保存用户信息，还是老方法SharedPreferences
