Nix Android CI Gradle Builds

I’m working on making android Gradle builds work in the nix build env.

I’m currently stuck with this issue Offline mode build dependencies fetching (AGP) from local repo - Help/Discuss - Gradle Forums. I post it here because I know that some of you are familiar with Gradle. Feel free to write on this thread if you don’t have a Gradle discuss account, it’s made for that.
