Session cookie not used

After many, many hours, I managed to figure out how to share cookies between my client and my webview. My problem right now is that for some reason my session file is not being used.

In android docs I found: public void setCookie (String url, String value) Because: API level 1 Set a cookie for the given URL. An old cookie with the same name / name / host will be deleted. A new cookie will be added if it has not expired or does not have an expiration date, which means that it is a session cookie.

A thing is a general cookie with a set expiration date and it works. Does anyone have any idea why my session cookie is not used or if it really is because setCookie cannot do this, how can I do it differently.

Here is my code:

            }
