    try {
            String[] Id,name;
          JSONObject json = new JSONObject(str);

          JSONObject SubString3 = json.getJSONObject("data");
          Log.e(SubString3.toString(),"SubString3");
          JSONArray Array = SubString3.getJSONArray("school");
          Id = new String[Array.length()];
          name =new String[Array.length()]; 
          for(int i=0;i<=Array.length();i++)
          {
              Id[i]= Array.getJSONObject(i).getString("id");
              Log.e(Id[i].toString(),"Id[i]");
              name[i]= Array.getJSONObject(i).getString("name");
              Log.e(name[i].toString(),"name[i]");
          }
      } catch (JSONException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
      }

The Category object is not present inside the Json file

you can try following

    JSONObject json = new JSONObject("str");
    JSONObject data = json.getJSONObject("data");
    JSONArray school = json.getJSONArray("school");

    for (int i = 0; i < data.length(); i++) {
        JSONObject object = school.getJSONObject(i);

        long id = Long.parseLong(object.getString("id"));
        String name = object.getString("name");
        JSONObject category = new JSONObject();
                    category.put("id");
                    category.put("name");




    }

First you need to fetch an OBJECT of the whole JSON because it's in '{' '}'. Then you need to fetch an object again with the name "data" because it is in '{' '}'. And only then should you fetch the array named "school".

JSONObject json = new JSONObject(str);
JSONObject data = json.getJSONObject("data");
JSONArray school = data.getJSONArray("school");
