I've implement the Samsung IAP plugin for Android.
Thanks to many people's help.
The plugin call method well in my project, but I didn't finish the whole purchase progress because I have some trouble in creating Samsung prepaid card. So, I submit the game with plugin for Samsung Store. I'm still waiting the review.
Hope everything OK. God bless my lazy......
So, if anyone have interest, welcome to have a look.https://github.com/freeman5860/gideros_plugin/tree/master/SamsungPlugin
