Provide pure-floss build flavor

[Deleted user]

Google Analytics (and most likely bugsnag?) is non-free software, could you provide a gradle flavor that does not require this?

Provide how? The debug build does not use either of these services.

Still they are required by build.gradle (and checked before anything is actually build) You can add build flavors like

productFlavors {
        play {
        }
        free {
        }
    }

and then marking the dependcies only with playCompile instead of compile. After that you can move all flavor related stuff out of src/main into /src/play or src/free instead. If this is possible with your app requires deeper knoledge of how and why those services are used.
