App install tracking?

Having experimented with Twitter’s CPI app install advertising, I found it was a problem not being able to track actual install events. Doing seems to involve integrating an SDK not supported in Corona. Google’s app install ads work the same way. Has anyone used any app install advertising that can be tracked via Corona?

I’m also interested in this. With so much competition an optimised ad campaign would really help - my corona games are using the Facebook publishinstall notification but I’d like to try other ad networks to get a lower CPI. It seems that an https://www.adjust.com plugin would go a long way to help here as it is supported by lots of networks (notably twitter). The adjust SDK is open source so it would seem to be pretty straightforward to turn it into a plugin.
