Currently ive been working on my very first android app (clap clap clap) thank you ive ran into the wall of not knowing how to include payments of real money from inventory objects any help?
You will need to integrate with someone that can handle the payments. For example, http://www.paymentwall.com/
Once a payment is made, it will send a callback to your server, where you can then add the item to that player. You will need a basic web server that manages your players however.
Thank you @zibber big help you da dog
