One subtlety about Brad's answer: even if you load the SharedPreferences in onCreate(), you should probably still read values on the background thread because getString() etc. block until reading the shared file preference in finishes (on a background thread):

public String getString(String key, String defValue) {
    synchronized (this) {
        awaitLoadedLocked();
        String v = (String)mMap.get(key);
        return v != null ? v : defValue;
    }
}

edit() also blocks in the same way, although apply() appears to be safe on the foreground thread.

(BTW sorry to put this down here. I would have put this as a comment to Brad's answer, but I just joined and don't have enough reputation to do so.)
