}
payment flow stating from here
private fun getHashkey() {
paymentParam!!.setMerchantHash(CreateHash())
PayUmoneyFlowManager.startPayUMoneyFlow(paymentParam, this as PaymentGateways, R.style.AppTheme_default, true);
}
generating hash key from this code
private fun CreateHash(): String {
var hashSequence: String = pro_merchantkey + "|" + txnid + "|" + amount + "|" + prodname + "|" + firstname + "|" + email + "|" +
udf1 + "|" + udf2 + "|" + udf3 + "|" + udf4 + "|" + udf5 +"||||||"+ pro_salt;
val hash = hashcal("SHA-512", hashSequence)
return hash
}
note :- i am getting only one payment option i want to get multiple payment options like netbanking ,Upi

you have set
setIsDebug()true; for some resaons PayU have only provided test cards for testing purposes. So, the release build will have all the options. in simple words setsetIsDebug(false)and you will get all the options.
