Shrinking Your APK, By Example
summary
Walks through making a toy cat‑pictures app shrink from ~2.2 MB to ~1.1 MB (and an xxhdpi split to ~800 KB) by using APK Analyzer to find big assets, converting PNGs to WebP (75% quality) and an MP3 to OGG to cut image/audio bytes, enabling ProGuard + resource shrinking while fixing AAPT keep rules (merged-manifest override to remove an unused activity), and publishing density splits with a version‑code math trick to serve smaller per-device APKs; notes an Instant Apps bug affecting resource shrinking.
