I mean technology should be to empower people not to emphasise on their level of literacy.
Integrating Paystack into Android Studio is really a challenge, uptil now i have not found a documented video on how to, only github guide which is not enough, Please do well to ask your team make videos on how to implement paystack on android studio this would encourage lots of Nigeria programmers to start using Paystack, I Love Paystack
