cannot use if or switch on jSONObject

I simply have an asynctask that use a listener to communicate with the main activity. Where the response arrive arrive, and the first Toast will been showen wuth correct values. the problem is that in the try catch i can recover the values. so if or switch dont work anymore.

   @Override
    public void OnAsyncTaskComplete(String response) {

        Toast.makeText(getContext(),((ActivityLogin) getActivity()).choiceButton+" result: "+response, Toast.LENGTH_LONG).show();

        try {
            JSONObject obj = new JSONObject(response);

            String objservice = obj.getString("service");
            String objstatuCode = obj.getString("status-code");
            String objdescription = obj.getString("status-description");

            JSONObject result = obj.getJSONObject("result");


            if(!objstatuCode.equals("200") || objstatuCode.equals(null)){
                Toast.makeText(getContext(), objstatuCode+"", Toast.LENGTH_SHORT).show();
                return;
            } else {
                Toast.makeText(getContext(), objstatuCode+"", Toast.LENGTH_SHORT).show();
                return;
            }



        } catch (JSONException e){
            e.printStackTrace();
        }


    }
