You just need to deal with being restarted due to a configuration change. Note that even if you force an orientation, this can still happen due to the user opening a keyboard, changing the locale, and for many other reasons.
It is true that even if you specify a particular orientation, you may see switches to other orientations in some cases as the user transitions in and out of your app. That doesn't mean your app needs to display and run properly in the other orientation, just don't crash and deal with the config being changed (which you need to do anyway).
