How to know if an app has been downloaded from Google Play or Amazon?
问题 Is there any way to know if an application has been downloaded from Amazon App Store or Google Play Store? I meant within the app itself, of course. I have deployed an app to both sites and I rather like to know from where the customer has downloaded it within the application. I know, I can deploy different applications to each service, but this adds some maintenance work that could be avoided if there were some manner to solve it just with a conditional within the app using the same package.
