I browsed games and applications on the Gear VR store and didn't find application with in-app purchase. I also browsed documentation (technical and submission).
Did I miss something, or is there no way to put in-app purchase on Gear VR applications?
Or maybe should I use classical android in-app system? But I don't think that the Gear let Android overlay in VR mode.
From what I can tell from the article it seams that it is just talking about the desktop store. I am not sure if the Gear VR store will get the multiple release channels feature.
