64-bit Adaptation Practices for iQIYI Android App

iQIYI migrated its Android app to 64‑bit by configuring ABI selection, delivering native libraries via universal or split APKs, plugin packages, and a cloud‑based SO distribution platform, adding a front‑end SDK and back‑end publishing service, and applying size‑reduction and hot‑fix optimizations, resulting in faster startup, better performance, and a unified library management workflow.
