For example, if you click the button a few times and get a different color and fact and then switch the orientation, it then resets to the hard coded activity layout. Can someone explain why this happens?
Thanks!

When you tilt your phone from portrait to landscape android actually closes your current activity and creates another in the relevant orientation. You can obviously code the app to continue (as most apps do) by making use of the methods called during the activity life cycle.
http://developer.android.com/training/basics/activity-lifecycle/index.html
Another approach is to force android to stay in one particular orientation (which i prefer for this app), you can do this by going to the android manifest and selecting your main activity to the right there will be a list of options go to Orientation and select portrait. If done correctly the app will now not change your current perspective when you tilt your phone and will therefore not restart your progress.
Hope this helps
