You do not want to put a Spinner in the onSaveInstanceState() Bundle.
Besides the fact that it is impossible, doing so would cause your new
activity to hold onto a reference to that Spinner, which holds onto a
reference to your old activity, which will cause a substantial memory
leak.
Your Spinner's contents are set via some sort of Adapter. You should
be making sure your new Activity can re-create that Adapter. Then, put
either getItemSelectedId() or getItemSelectedPosition() in the Bundle,
so you can restore the selection in the new Activity.
