Build me a simple Android demo app that looks like a fake lock screen for a security awareness project, with a custom app name, icon, warning title, warning message, and an unlock code screen.

I want it to be easy to personalize, package into an APK, and run on Android for a harmless demo, not anything that actually locks or harms a device. Please keep the setup simple, include an install script if needed, and make the interface look polished enough for a classroom or proof of concept. If you need current build or packaging steps, look up the latest docs online.
