This is the idiom I've used for years and I've never had anyone bat an eye at it. I do the same for unmodifiable constant Sets and Lists too.

How would I handle a HashMap<String, String> with a String key. The Map object doesn't allow me to have a String key so I can't use unmodifiableMap(). I guess casting to a HashMap would defeat the purpose as well. Any ideas?

@Luke I seriously doubt that Android has such a limitation. It makes no sense at all. A quick search found this question here (and many others) which seems to imply you can use a String key for a Map object in Android.

So no one else bothers to investigate, I can confirm there's no problem with using a String key for a Map object on Android.

Jordan: it is an old topic now but I suspect @Luke was trying to use a string as a key in a map that had a different key type, e.g. Map<Integer, String>.
