Android小记-根据domain清除cookie

Android WebView中可以直接全部清除cookie，但如果我们想要根据某个域名指定清除cookie，则大概代码如下：

必要方法：

    public static void clearCookieByUrl(String url, CookieManager pCookieManager, CookieSyncManager pCookieSyncManager) {        Uri uri = Uri.parse(url);        String host = uri.getHost();        clearCookieByUrlInternal(url, pCookieManager, pCookieSyncManager);        clearCookieByUrlInternal("http://." + host, pCookieManager, pCookieSyncManager);        clearCookieByUrlInternal("https://." + host, pCookieManager, pCookieSyncManager);    }    private static void clearCookieByUrlInternal(String url, CookieManager pCookieManager, CookieSyncManager pCookieSyncManager) {        if (TextUtils.isEmpty(url)) {            return;        }        String cookieString = pCookieManager.getCookie(url);        Vector<String> cookie = getCookieNamesByUrl(cookieString);        if (cookie == null || cookie.isEmpty()) {            return;        }        int len = cookie.size();        for (int i = 0; i < len; i++) {            pCookieManager.setCookie(url, cookie.get(i) + "=-1");        }        pCookieSyncManager.sync();    }    private static Vector<String> getCookieNamesByUrl(String cookie) {        if (TextUtils.isEmpty(cookie)) {            return null;        }        String[] cookieField = cookie.split(";");        int len = cookieField.length;        for (int i = 0; i < len; i++) {            cookieField[i] = cookieField[i].trim();        }        Vector<String> allCookieField = new Vector<String>();        for (int i = 0; i < len; i++) {            if (TextUtils.isEmpty(cookieField[i])) {                continue;            }            if (!cookieField[i].contains("=")) {                continue;            }            String[] singleCookieField = cookieField[i].split("=");            allCookieField.add(singleCookieField[0]);        }        if (allCookieField.isEmpty()) {            return null;        }        return allCookieField;    }

调用方式：

        String domainUrl = "http://www.facebook.com";        CookieManager mCookieManager = CookieManager.getInstance();        CookieSyncManager mCookieSyncManager = CookieSyncManager.createInstance(getApplicationContext());        Utils.clearCookieByUrl(domainUrl , mCookieManager, mCookieSyncManager);
