== The Fabric Plugin and Crashlytics

The https://docs.fabric.io/android/fabric/overview.html[Fabric] plugin, which is used to integrate the Crashlytics crash-reporting tool (among others), is very popular, yet imposes some hefty performance penalties during the build process.
This is due to the need for each version of your app to have a unique identifier so that it can be identified in the Crashlytics dashboard.
