What is your aim? Do you want to create a real and/or virtual mashine
for a specific service, like building replicant?

Or do you want to provide a developer environment in a reproducible
way? For the latter, the command "guix environment" might be all you
need: It provides you with an environment that contains the packages
you need (or the build-time dependencies of a package you want to
develop on). See [0] for more.

In either way, one of the problems might be that not everything is
in Guix that you need as a Replicant/Android developer. Guix is a GNU
project and as such sticks to the GNU FSDG. That means, only free
software is part of Guix. Furthermore, Guix tries to stick to
bootstrappable builds [1]. That said, some packages you need might not
be part of Guix proper (yet). For example, Gradle has a dependency that
is written in SBT/Scala. The Scala compiler needs a Scala compiler to be
built. Noone has yet written a Scala compiler that bootstraps from a
different langage other than Scala.

You can clone Guix or use a socalled "Channel" to add your binary
packages to your Guix (and bootstrap them properly later).

I can look over your Guix code, if you like.

If you give me [2] Wiki access, I can add some Guix information to [3].
