SiriLV/Andlinux — reverse-engineered prompt

Build me an Android app that gives me a real Linux terminal on my phone without needing root. I want it to install like a normal APK, download what it needs on first launch, then set up the latest stable Alpine Linux inside the app using proot. It should also let me open a plain Android shell if I do not want to enter Alpine.

Make the terminal feel good on mobile, with multiple sessions, a side menu to switch between them, extra on screen keys like Esc, Ctrl, Alt and arrows, and settings for text size, scrollback, shortcuts, font, background image, transparency, and showing or hiding bars and virtual keys. Let me choose my default shell in Alpine, including ash, bash, fish, and zsh, and install it automatically if missing.

On first setup, ask for a visible username and hostname and use that in the prompt. I also want built in themes that style both the terminal and the app UI. Please make sure it builds into a release APK. Look up current Android docs if you need to.
