If you have access to some JSON library, it seems like that's the way to go.

If using org.json library, use public JSONObject(java.util.Map map):

String jsonString = new JSONObject(data).toString()

If Gson, use the gson.toJson() method mentioned by @hellboy:

String jsonString = new Gson().toJson(data, Map.class);
