/* if respond is object respond = { "a": "a", "b" : [1,2] } */ JSONObject jo = new JSONObject(respond); String a = jo.getString("a"); // a JSONArray ja2 = jo.getJSONArray("b"); // [1,2] int one = ja2.getInt(0) // 1

/* if respond is array respond = [ {"a": "a", "b" : [1,2] } ] */ JSONArray ja1 = new JSONArray(respond); JSONObject jo= ja1.getJSONObject(0); // {"a": "a", "b" : [1,2] } String a = jo.getString("a"); // a JSONArray ja2 = jo.getJSONArray("b"); // [1,2]
