Your "put" and "get" operations use different keys:
this.gameState.getClass().getName() // Can vary with the actual class of
gameState
and
GameState.class.getName() // Always "GameState"
presumably you have various subclasses of GameState, so there is a
mismatch and thus "gameState.setState()" crashes with a null pointer.
Just define a string constant and use it as the key in both places:
private static final String GAME_STATE_KEY =
"com.wright.james.GAME_STATE_KEY";
b.putParcelable(GAME_STATE_KEY, gameState)
and
gameState = bundle.getParcelable(GAME_STATE_KEY)

protected void onSaveInstanceState(Bundle b) {
b.putParcelable(this.gameState.getClass().getName(),
this.gameState);
super.onSaveInstanceState(b);
}
and retrieved in Activity's OnCreate as follows:
if (bundle != null&& !bundle.isEmpty()) {
gameState = (GameState)
bundle.getParcelable(GameState.class
.getName());
gameState.setState(State.REGULAR);
}
