Android: HttpClient与Webview共享cookies

本人最近和别人合做一个app应用，app加webview。
app登陆有webview也要是登陆状态，解决的办法是app登陆后把设置下cookie

httpclient与webview需要进行cookie 共享，因为如果不共享，那么假设你在httpclient进行了登录，然后用webview里打开那些login之后才能看的page，就会叫你再login

DefaultHttpClient httpclient=....;  
String toUrl="https://cap.cityu.edu.hk/studentlan/details.aspx.....";  
  
List<Cookie> cookies = httpclient.getCookieStore().getCookies();  
  
if (! cookies.isEmpty()){  
    CookieSyncManager.createInstance(this);  
    CookieManager cookieManager = CookieManager.getInstance();  
        //sync all the cookies in the httpclient with the webview by generating cookie string  
    for (Cookie cookie : cookies){  
        String cookieString = cookie.getName() + "=" + cookie.getValue() + "; domain=" + cookie.getDomain();  
        cookieManager.setCookie(toUrl, cookieString);  
        CookieSyncManager.getInstance().sync();  
    }  
}
