Answer 1

simply use

 if (throwable is HttpException && (throwable!!.code() == 400 || throwable!!.code()==404)){
                               var responseBody = throwable!!.response()?.errorBody()?.string()
                               val jsonObject = JSONObject(responseBody!!.trim())
                               var message = jsonObject.getString("message")
                               tvValMsg.set(message)
                            }
