onSuccess() does not get triggered

[raheemadamboev]

In order to make a payment, user needs to go out of application and he has several options, right. Via telegram bot, Click application and USSD these are good options. But user has to go outside of the application that this SDK implemented.

If user does not come back to application, it is obvious that onSuccess() method does not get triggered. So the code that must be executed after payment is successfull never gets executed. Basically user gets nothing and thinks he got scammed.

Is it possible to make payment without going outside of the application, or there another way of achieving it?
