Covers app signing by Google Play (upload key + Play‑held release key), the Play Core split install API and SplitCompat, the local testing tool bundletool, and a new internal test track for up to 100 testers. Shows dynamic feature modules loaded on demand and that the system works across pre‑ and post‑Lollipop devices.
