R1punk/SARA ? reverse-engineered prompt

Build me a simple Python based tool that can take an Android app and package it with a custom icon, app name, alert title, alert message, and a password for an unlock screen, so I can use it for a security awareness demo in a lab.

I want it to run from the command line on Linux and also have a version that can work in Termux on rooted Android. Please make the setup easy, with an install script and clear steps to build the APK. If you need to check current docs or tooling details online, go ahead.

Keep the output straightforward, show progress while it runs, and save the finished APK somewhere obvious. I also want the script to be easy to edit so I can change the text and branding without digging through a lot of code.
