OK, so I'm playing around with an android app.

The 90% use case is that users want to go straight to the primary list screen to find what they're looking for. That's what I want as my default screen.

The first time a user loads the app however, some configuration is required before their list screen is of any value to them.

So my question, is how I can go about displaying the configuration activity the first time the app is opened up, and then the list screen for future openings.

I also want to put a demo button on the configuration screen, so I suppose more than just detecting that it's the first time, I specifically want to detect whether the user has performed certain configurations within the first screen.
