The guide explains how game publishers can modify Android App Bundles—using bundletool to decompile, update icons (including adaptive ones), change app names across languages, and adjust base or PAD resources—then re‑package the AAB for Google Play compliance.
The workflow extracts PAD assets from an AAB, builds a universal APK with bundletool, runs the legacy APK split pipeline, then reassembles a new AAB by merging the split base module with the saved PAD zip, preserving Play Asset Delivery for Google Play compliance.
Starting in August 2021, Google Play will mandate that all newly published Android apps be distributed as Android App Bundles (AAB), a format that reduces app size by about 15% and enables dynamic delivery features, while existing apps remain unaffected.
This article explores the motivations, methodology, and practical implementation of converting existing Android business libraries into Dynamic Feature modules with minimal intrusion, covering Android App Bundle basics, build tools, dependency handling, resource merging, Arouter integration, and performance gains achieved through parallel and incremental builds.
Qigsaw, iQIYI’s open‑source framework released in 2019, enables low‑risk dynamic loading of Android App Bundle split APKs across all components and processes, offering Play‑Core‑compatible APIs, single‑hook stability, resource merging, and Tinker‑based hot updates, thereby simplifying plugin integration and reducing app size.
