Question

Answer 1

Use JSONObject constructor. DON"T CREATE YOUR OWN since you might miss some cases such when the value is an array.

JSONObject jsonObject = new JSONObject(hashMap);

This is actually a complete solution since it covers for corner cases such as where the value is an array. Thus, it will make it as JSONArray for you.
