Apps IAB V3 - get onActivityResult from outside

[refaelos]

I'm trying to implement Android's IAB V3 and it asks that i override 'onActivityResult' in my Activity and use it to handle the IAB response.

My problem is that there are cases where i don't have access to the Activity and i need to intercept 'onActivityResult' for my needs. Is it possible to get a callback when an Intent finishes and get all the result data from it ?

Generally, what i'm trying to do is use IAB V3 without and Activity or with a dummy Activity. Is it possible ?

Thanks!
