You should use CookieManager.setCookie() and set the cookie to the empty string. Something like this should work:

String cookieString = "cookieName=''";
cookieManager.setCookie(cookieDomain, cookieString);

In addition to setting the cookie value to empty, you can also expire the cookie by setting the 'expire' value in the cookie string to a time in the past. For example:

String cookieString = "cookieName=;expires=Mon, 17 Oct 2011 10:47:11 UTC;";
