android WebView 设置cookie和清除Cookie

   public static boolean syncCookie(String url, String cookie, Context context) {
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
            CookieSyncManager.createInstance(context);
        }
        CookieManager cookieManager = CookieManager.getInstance();
        cookieManager.setCookie(url, cookie);//如果没有特殊需求，这里只需要将session id以"key=value"形式作为cookie即可
        String newCookie = cookieManager.getCookie(url);
        return TextUtils.isEmpty(newCookie) ? false : true;
    }

 

 public static void clearCookies(Context context) {

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1) {
            Log.i(TAG, "Using clearCookies code for API >=" + String.valueOf(Build.VERSION_CODES.LOLLIPOP_MR1));
            CookieManager.getInstance().removeAllCookies(null);
            CookieManager.getInstance().flush();
        } else {
            Log.d(TAG, "Using clearCookies code for API <" + String.valueOf(Build.VERSION_CODES.LOLLIPOP_MR1));
            CookieSyncManager cookieSyncMngr = CookieSyncManager.createInstance(context);
            cookieSyncMngr.startSync();
            CookieManager cookieManager = CookieManager.getInstance();
            cookieManager.removeAllCookie();
            cookieManager.removeSessionCookie();
            cookieSyncMngr.stopSync();
            cookieSyncMngr.sync();
        }
    }
