My app has a 3-tabbed ActionBar layout. The 3 tabs are Dashboard, Feed and Messages.
When you click any of the three, the application is supposed to create a WebView of www.flyalaskava.org/incog/mobile/ which - if you do not have an active session for - will display an image and a "log-in with facebook" button.
The problem is, when I load the first tab (Dashboard) and cliek Log-In with Facebook, it logs me in - but as soon as I click onto another tab, I lose my session and am re-prompted.
Please keep in mind that currently all of these are using the same php file and that the log-in system works perfectly outside of Android. Sorry if this is a newbie question - any help is appreciated.

*\\\\\\\\UPDATE\\\\\\*
I found this article which seems to be a similar problem, maybe because im using mWebView.loadUrl("http://www.flyalaskava.org/incog/mobile/"); it is acting like a new browser, is there any way to change urls without using that method.
Here is a picture of the problem.
