Build your android app without the Android Gradle Plugin

Replaces AGP with a minimal custom Gradle plugin that actually runs AAPT2 to compile resources, merges manifests into a single AndroidManifest.xml, invokes javac and kotlinc to emit class files, runs D8 to dex, zips an unsigned APK, signs it with a keystore, and installs via adb. Shows generated artifacts like R.txt and unsigned APK, explains cachable Gradle task annotations, inputs/outputs wiring, and where each tool is downloaded and cached.
