alt Hacker Newsyou already could! just install Termux, npm install your favourite agent harness (pi for one has explicit Termux support, but its AGENTS.md works just fine with Claude Code for example - https://github.com/badlogic/pi-mono/blob/main/packages/codin...), and say you want an android app. It problem solves for a bit, then spits out an apk out to your Downloads folder.
Let me try this. Last year this was a dream. Can't belive we are so close to automate all of this.
My major issue last time was providing the feedback to the agent by running the apk on phone i.e, pass the debug log from the apk back to agent so it can iterate on it without me providing any input.
