I didn't try it out, maybe you're right. I know how to deploy my stuff via systemd, install Rust/cargo/Elm/Python/Node/GHC/libopencv/Nix/whatever, link static libs and so on. And when I'm using Raspberry Pi I need near-zero new knowledge to do all that.
I suspect that trying something like that on Android will be a long road with lots of caveats, even if possible, learning to do all the things the new "Android" way. Am I wrong?
For building native code it will mostly be the same, but you will need to learn some Android stuff for making the nonnative part of your app so you can learn how to create a background service and how to tell Android to restart your service if it gets killed due to low memory.
