Dear Community!

 

My plan is develop application for GooglePlay! I want to take money only inside application! 

( Inner purchase. ) (So, it will COMMERCIAL software for GooglePlay!!!)
How can I detect in Delphi Professional, if downloader payed or not??? (Android, GooglePlay)

 

Where can I find this? Some example source code?
