There is some changes im remember, where im moved all public security keys to strings.xml and not in glbasic, because its was hard to meanstream it, after the new StoreKey update, where google phased out v2 purchase system, and the init was required to been done in OnCreate now, which is invoked before any glbasic code started. SKU was still can do in the inapp_config.gbas throught.
But the idea and functions is pretty much the same, and actuelly im did newer do a real example of this system. Im thinks one of your guys, should do a proper example in the default android example to show off how those works?
Howover im will see can do in the follow weeks to create a inapp purchase example and doing that in the normal android extras example.... There was as im wrote few updates, but only how the public keys is implemented, not the functions its self.
PS. Im do no longer support Google Ads, so im can no longer help on that one. The reason behind, Google Ads have been shown unstablilty and have a lots of malware for its users. Also im also seen, while its works nicely here, its can crash on other devices. So its was a hit or miss.... And, its diddent work on Android TV at all. So im will then focus to doing a better inapp purchase example. But a release might first do after my vaccation, so some where in Aug first.
