As the docs say, the onRetainNonConfigurationInstance() should only be used as an optimization, not to replace a working implementation of the normal onSaveInstanceState() et al mechanism. (The latter is the only thing that can be done in the case where an app's process needs to be killed or its activities removed while in the background, which is what destroying activities immediately emulates.)
At any rate, you should be able to put a styled CharSequence into a bundle (or use the TextUtils class to write it directly to a Parcel) and get it out again with the styling intact. Unfortunately this currently only works for the built-in styleable classes, so if you need to retain your own custom ones you will probably do your own marshalling/unmarshalling with the Parcel.
