I'm setting up for the first time GameAnalytics in my Unity3D project. I'm try to figure out if there is a way to validate in app purchases for both android and iOS from it.
In the docs I found http://www.gameanalytics.com/docs/ga-data#business-event. I understood that you need to work with native sdks to get this feature, am I right?
Could it be an option to configure from the dashboard an android and an iOS game and then changing the keys in unity with precompilator instructions? (like #if UNITY_ANDROID)?
When you install the Game Analytics unity package, you are essentially installing the native libraries for each platform (Android, iOS, ...) located in the Plugins folder.
If you want to target multiple platforms in your code with an API like Game Analytics, I recommend you use the preprocessor tags as you mentioned since the functions from Game Analytics are platform specific.
