                },
                {"item":
                   [{"id":"goals1","label":"Goals"}]
                },
                {"item":
                    [{"id":"rprojects1","label":"Reference Projects"}]
                },
                {"item":
                      [{"id":"iwh1","label":"Internal Work History"}]
                },
                {"item":
                     [{"id":"ewh1","label":"EXternal Work History"}]
                }
                ]
        },{.....}
 ]
 }

i need to parse the data and get the values of id,label ,i write some code to parse the data but it didnt work.

  JSONObject subObj = new JSONObject(data2);
  JSONObject innerObj1 = subObj.getJSONObject("result");
  JSONObject subArrayObj = innerObj1.getJSONObject("menu_items");
  for(int j =0;j < subArrayObj.length();j++) {
  JSONObject innsersubObj = subArrayObj.getJSONObject("item");
  String id = innsersubObj.getString("id");
  String label = innsersubObj.getString("label");
  Log.e("id",id);
  Log.e("label",label);
   }

How to parse the data any thing need to change in the code ?

You have to use JSONObject and JSONArray are different objects, you have to use correct class:

JSONArray resultArray = subObj.getJSONArray("result");
JSONObject firstItem = resultArray.getJSONObject(0);
JSONArray menuItems = firstItem.getJSONArray("menu_items");

etc.

JSONARRAY subArrayObj = innerObj1.getJSONARRAY("menu_items");

Since menu_items is returning an array..it should be collected in an array object..

JSONObject innsersubObj = subArrayObj.getJSONObject("item");

Yes, it will show an error.. Bec you have to use index of an array then you can fetch "item".. You can use a for loop and use get JSONOBJECT (i) method to do so.. Then inside loop u can have "item" which will again return an array.. So, basically use the correct classes by seeing the R.H.S that what it is returning.
