Build Android APK without Android Studio, Gradle, or internet

Run R8/ProGuard on Android APK without Gradle — shrink, obfuscate and minify DEX using R8 that's already inside d8.jar

Build a minimal Android game APK (like Tetris) from scratch using only Java, Canvas, and android.jar — no Gradle, no Kotlin, no libraries. Result: 16KB APK.
