I used Claude Code. I actually just asked it what tools I needed for a CLI-driven build, and it told me what to install (or even installed it for me in some cases). I basically didn't read any documentation, just asked Claude what I should do.
Edit: Holy shit, in 30 minutes I used Claude code to make a simple PDF viewer app, and it totally works. I did have to prompt it through the process quite a bit, including correcting some obvious flubs, but I'm super impressed.
I didn't even have to install the android dev tools because I asked it to generate a Dockerfile in which to do the build, and a simple script to copy the apk out when done :-D
