Android: HttpClient与Webview共享cookies

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();
}
}
