I'm integrating payuMoney (not payu biz) in my android application. I followed this official documentation of PayuMoney. I have changed merchant key, merchant id and url of hash generation of my server in this sample app. Then it is taking me to PayuMoney sdk screen where I can login/signup. But it is showing the toast message 'Some error occured! Try again' once I login with my credentials. Is there anything else that I'm missing? Please guide me.
This happens because you might not have activated your account on PayUMoney. Try contacting the customer service and get your account activatied. The error will be resolved.
This happens when server generated hash not equal to payUmoney generated hash so payUmoney don't allow payments
also, shows blank screen after login
to fix it generate a hash like this formate
String hashSequence=KEY+"|"+txn+"|"+amount+"|"+productinfo+"|"+firstname+"|"+email+"|"+UDF1+"|"+UDF2+"|"+UDF3+"|"+UDF4+"|"+UDF5+"|"+SALT;
