public void synCookies(String url,String cookies) {?
LogUtil.d(tag, "synCookies:"+url);
??? CookieSyncManager.createInstance(mContext);?
??? CookieManager cookieManager = CookieManager.getInstance();?
??? cookieManager.setAcceptCookie(true);?
??? LogUtil.d(tag, "cookie:"+cookies);
??? cookieManager.setCookie(url, cookies);//cookies是在HttpClient中获得的cookie?
??? CookieSyncManager.getInstance().sync();?
??
??? LogUtil.d(tag, "cookie:"+cookieManager.getCookie(url));
}

?String cookies = "sid=" + sessionId +";domain=域名;";
