                            //Do not generate hash from local,
                            // it needs to be calculated from server side only. Here,
                            // hashString contains hash created from your server side.
                            val hash: String? = hashString

                            if (!TextUtils.isEmpty(hash)) {
                                val dataMap: HashMap<String, String?> = HashMap()
                                dataMap[hashName!!] = hash!!
                                hashGenerationListener.onHashGenerated(dataMap)
                            }
                        }
                    }
                })
        }

Hash generation in local and i tried to generate in server also...

The test values given in the website no longer works use these values I've got by sending a complaint mail

key -> 'gtKFFx'
merchantSalt -> '4R38IvwiV57FwVpsgOvTXBdLE4tHUXFW'
