Android 给WebView设置Cookie

最近项目中用到WebView访问新浪支付页面，有个要求是必须是登录状态，否则会报Token过期，然后我简单的将我从cookie中取得的ticket，即一串数字可以代表用户登录的唯一标识作为参数拼接到url路径上，竟然成功了，但是，当在新浪页面进入第二级界面的时候，还会报Token过期，这才意识到，还是新浪网页没有获取到cookie。
可是ios也是用的webview访问的新浪支付，并且没有设置任何属性，新浪就可以获取到cookie。百度了一番，当然如何获取cookie，自己百度查查吧，我这是已经获取到cookie之后的操作。注意的是要在WebView.loadUrl()之前调用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();
//以下是我们在请求中获取到的cookie相关信息，然后存到本地，你需要做的就是 将自己的cookie 中的信息分别取出来 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");
//然后分别拼到StringBuilder 上，然后通过cookieManager.setCookie(url, cookieValue);最后再进行同步，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("==异常==", e.toString());
}
}
另外提供一个工具类：
package com.hibo.bm.utils;
import android.content.Context;
import android.os.Build;
import android.util.Log;
import android.webkit.CookieManager;
import android.webkit.CookieSyncManager;
import android.webkit.WebView;
import com.hibo.bm.url.AppUrl;
import org.xutils.http.cookie.DbCookieStore;
import java.net.HttpCookie;
import java.util.List;
