Stay Calm and Modularize

" summary

Modularizing a simple app takes less than a day using Android Studio’s refactor modularize tool and splitting into an instant app module, an installed module, per-feature modules and a single base module; the build produces a zip of mini‑APKs so each feature downloads on demand. Instant features must be under 4 MB (base + feature) and the APK analyzer verifies sizes. Practical shrink tactics: ProGuard (saved ~600 KB on one base module), convert images to WebP, downloadable fonts, and Gradle flavors to swap Picasso vs bundled images.
