Creating a Stack Overflow notifier

I could not find a Stack Overflow notifier Android app so I am planning on making one. I hope that my app will serve a similar purpose as the Stack Overflow Notifier Chrome extension. This will be my first Android app so I am still unfamiliar with the platform.

So I currently plan to ask the user to login by bringing up a WebView and then access the Recent Activity page in the background at specific intervals.

My question: How can I store the authentication cookie from StackOverflow after the user has logged in through the WebView and then send t开发者_如何学运维his cookie in the HttpGet request when accessing the Recent Activity page?

Stack Overflow is challenging because there is no username and password - you need to be able to allow the user to login fully with their OpenID setup.

An embedded browser where you can read the StackOverflow cookie would be the best choice.
