build-settings-shortcut.sh: One-Tap Android Settings Shortcuts, Built From a Single Bash Script

This article presents build-settings-shortcut.sh, a self-contained Bash script that creates minimal Android APKs for quickly accessing 20 different system settings screens (WiFi, Bluetooth, Hotspot, Battery, Developer Options, etc.). The script downloads its own toolchain (JDK 17, Android SDK, Gradle) into a local directory, builds a Kotlin project, fetches Material Symbols icons, and produces a debug APK that opens the specified settings activity and closes. It supports fallback to public Settings.ACTION_* intents for cross-vendor compatibility. The article explains usage, features like no root requirement, and how it caches icons and toolchain for efficiency.
