Yes, changing the screen orientation means going through onCreate() onResume() which, if your activity is implemented correctly, should be transparent, since you also need to deal with this same thing happening when your process is killed in the background and the user returns to the app. As a result, there is pretty extensive support in the system for remember the state of activities, lists, etc, and restoring them when being re-created.
See the API demos for saving and restoring state for a simple example. This is how most apps in the emulator work, so it is not a design flaw.
