Forget everything you know about APKs
summary
Explains that the Android App Bundle replaces multi‑APK chaos (developers used to manage 20–60 APK variants) and enables Google Play Dynamic Delivery: upload a .aab, Play uses bundletool to produce device‑specific split APKs and apply APK signature v2 and Play App Signing. Dynamic feature modules install on demand via the Play Core SplitInstallManager and require SplitCompat and context/asset handling; demos show Sudoku generator and JNI libs downloaded and run live, though live demo installs can be flaky. Instant apps go from 4MB to 10MB (beta) and language splits can save megabytes.
