Sorry for recreating new topic since this was asked but I think in this 2020 maybe there are some tools and ways to do this!
Why do I want to change my aia to android studio? it is because I have tried to use IAB component but it is not working for me, so I think using Android studio will be easy.
But if one will help me to know how I can implement IAB on my app then there will be no need to think of android studio.
