I think we’re close now to reintegrating the changes back into Nixpkgs. The only showstopper is the fact that cross compilation to Android will be broken, for which I need help.
The other issue is that the androidenv.buildGradleApp function is still not ported. I don’t use this function myself, and I don’t have the means to validate it. I did not receive any comments about it yet (or any fixes), so I assume that it’s not extensively used. Furthermore, since there is no gradle2nix yet (or at least an implementation that works) I think this function is also quite limited, because it can’t use any external dependencies in a pure build environment.
Anyway, if somebody thinks that the buildGradleApp function is a showstopper then please let me know.
