Flickr Sign out in Android programmatically

I am getting some issue when image is uploaded to flickr,oath token as well as user credentials get stored in the web browser cache.As a result am not being able to sign out from it.So when I go to flickr to upload my image again,it automatically uploads it rather than opening the login page.Now when I clear all the default browser cookies,then it ask for the login page.Is there any other way to sign out it automatically when I am redirected back to my application.Any kind of support will be appreciated.
Thanks in advance...

I think it is a bad idea to make your activity parcelable. Activities are not supposed to be transported via intents. And if your activities are inside the same application, you do not need transport via intent at all - just stick with standard java mechanisms.
