I´ve setup crashlytics for android using the suggested gradle method and while running in android studio things work fine. I get crash reports, statistics and everything just as expected (and looking great btw!).
The problem is when I want to use the same features in our release environment. We´re using APKtool on a build server to modify resources, package name and a few other things. Basically, we are producing a lot of release APKs all based on exactly the same code. When I run the produced release APKs nothing gets reported to crashlytics. From what I´ve understood it seems crashlytics communicates with the fabric API during the build process and since we are essentially creating a new APK (with a new package name) we probably need to do this manually somehow.
I´ve seen it mentioned in the ios beta distribution docs that you can run a script to submit created builds to the API so is there something similar available for Android, preferably without changing our whole build process?
