In the Android 2.2 SDK there's a sample app (new for 2.2) called
"Spinner" that demonstrates how to do this using SharedPreferences. It
will save the state of the spinner across pause() and resume(), and
also across app shutdown and restart.
Even better, it comes with a test package project called SpinnerTest
that demonstrates the unit test for this.
And best of all, the Activity Testing tutorial uses this app and its
test package to demonstrate unit testing in Android.
Enjoy!
