So, we had a discussion a while back about using FGL Enhance to inject ads, analytics and other services into a mobile app. At that time it still required a little bit of code to be manually added to the game and a small JAR included. This will, as most of you know, not work due to the nature of the Defold engine and build pipeline.
FGL has (recently?) added support for a ZeroCode option where a Pre-Roll ads are injected into an APK. This is, as the name implies, done without the need for any code at all. You simply upload the APK and let the FGL Enhance service do its magic and in a minute or two you get your APK back with Pre-Roll ads injected. I tried it on an Android app and it worked like a charm. Try it yourself!
