How to remove cookies using CookieManager for a specific domain?

Question

I know about the existince of CookieManager, but how do I remove cookies of a domain only?

Can someone help me with some code fragment?

Answer 1

Here is a code sample from an open source project. Maybe could help someone.

https://github.com/janrain/engage.android/blob/96f21b45738ef82a911e27d8a707aff3a1024d36/Jump/src/com/janrain/android/utils/WebViewUtils.java

private static void deleteWebViewCookiesForDomain(Context context, String domain, boolean secure) {
    CookieSyncManager csm = CookieSyncManager.createInstance(context);
    CookieManager cm = CookieManager.getInstance();

    /* http://code.google.com/p/android/issues/detail?id=19294 */
    if (AndroidUtils.SDK_INT >= 11) {
        // don't trim leading '.'s
    } else {
        /* Trim leading '.'s */
        if (domain.startsWith(".")) domain = domain.substring(1);
    }

    /* Cookies are stored by domain, and are not different for different schemes (i.e. http vs
     * https) (although they do have an optional 'secure' flag.) */
    domain = "http" + (secure ? "s" : "") + "://" + domain;
    String cookieGlob = cm.getCookie(domain);
    if (cookieGlob != null) {
        String[] cookies = cookieGlob.split(";");
        for (String cookieTuple : cookies) {
            String[] cookieParts = cookieTuple.split("=");

            /* setCookie has changed a lot between different versions of Android with respect to
             * how it handles cookies like these, which are set in order to clear an existing
             * cookie.  This way of invoking it seems to work on all versions. */
            cm.setCookie(domain, cookieParts[0] + "=;");

            /* These calls have worked for some subset of the the set of all versions of
             * Android:
             * cm.setCookie(domain, cookieParts[0] + "=");
             * cm.setCookie(domain, cookieParts[0]); */
        }
        csm.sync();
    }
}
