Another good solution is to use GSON. Here's an example:

private static final String MAP = "map";    
private static final Type MAP_TYPE = new TypeToken>() {}.getType();

private static SharedPreferences prefs = MyApplication.getContext().getSharedPreferences(PREFS_NAME, Context.MODE_PRIVATE);

private static Map myMap;

public static void saveMap (Map map) {
    SharedPreferences.Editor editor = prefs.edit();

    editor.putString(MAP, new Gson().toJson(map));
    editor.commit();
    myMap = map;
}

public static Map loadMap() {
    if (myMap == null) {
        myMap = new Gson().fromJson(prefs.getString(MAP, null), MAP_TYPE);
    }
    return myMap;
}
