Directly put JsonObject i.e. obj into jsonArray

jsonArray.put(obj);
//result is [{ "abc":"test","bed":"cot","help":"me"}]

Final code

JSONObject obj= new JSONObject(str);
JSONArray jsonArray = new JSONArray();
//simply put obj into jsonArray
jsonArray.put(obj);
//result is [{ "abc":"test","bed":"cot","help":"me"}]

It works for me.

JSONObject obj = new JSONObject(result.toString());
JSONArray arr = obj.getJSONArray("value");

Passing string in JSONObject(string) but still getting error . Provided type Map while required type is String.
