Android 給WebView設置Cookie

最近項目中用到WebView訪問新浪支付頁面，有個要求是必須是登錄狀態，否則會報Token過期，然后我簡單的將我從cookie中取得的ticket，即一串數字可以代表用戶登錄的唯一標識作為參數拼接到url路徑上，竟然成功了，但是，當在新浪頁面進入第二級界面的時候，還會報Token過期，這才意識到，還是新浪網頁沒有獲取到cookie。
    可是ios也是用的webview訪問的新浪支付，並且沒有設置任何屬性，新浪就可以獲取到cookie。百度了一番，當然如何獲取cookie，自己百度查查吧，我這是已經獲取到cookie之后的操作。注意的是要在WebView.loadUrl()之前調用syncCookie方法：
    public  void syncCookie(Context context, String url) {
        try {
            CookieSyncManager.createInstance(context);
            CookieManager cookieManager = CookieManager.getInstance();
            cookieManager.setAcceptCookie(true);
            cookieManager.removeSessionCookie();// 移除
            cookieManager.removeAllCookie();
            //以下是我們在請求中獲取到的cookie相關信息，然后存到本地，你需要做的就是 將自己的cookie 中的信息分別取出來 如：
//            cookie0: SFFGDFEID=0F7AE910509938FE024D6F94CB882DCA
//            cookie1： Domain=.dotyre.cn
//            cookie3:  Expires=Sat, 12-Aug-2017 05:41:47 GMT
//            cookie4:  Path=/
            String cookie = SharedPreferencesUtils.getString(context, "cookie0");
            String domain = SharedPreferencesUtils.getString(context, "cookie1");
            String path = SharedPreferencesUtils.getString(context, "cookie4");
            //然后分別拼到StringBuilder 上，然后通過cookieManager.setCookie(url, cookieValue);最后再進行同步，Cook//ieSyncManager.getInstance().sync();
            StringBuilder sbCookie = new StringBuilder();
            sbCookie.append(cookie);
            //       sbCookie.append(String.format(";domain=%s", domain));
            //       sbCookie.append(String.format(";path=%s", path));
            sbCookie.append(";"+domain);
            sbCookie.append(";"+path);
            String cookieValue = sbCookie.toString();
            Log.e("==cookieValue==", cookieValue);
            cookieManager.setCookie(url, cookieValue);
            CookieSyncManager.getInstance().sync();
        } catch (Exception e) {
            Log.e("==異常==", e.toString());
        }
    }
    另外提供一個工具類：
