Baidu reduced the iOS app package by over 350 MB by discarding dead code, replacing unreliable Mach‑O analysis with a source‑level AST approach built on LLVM libtooling and the Swift compiler, and implementing a multi‑layer static‑analysis pipeline that extracts, transforms, stores, and filters method usage data.
This article details the systematic reduction of the JD Finance Android app's APK size from 117 MB to 74 MB between 2019 and 2022, covering background analysis, APK and SDK component breakdown, a series of optimization techniques—including image processing, resource inlining, compression tools, dynamic SO loading, and pluginization—plus governance, results, and future plans.
Facing a 420 MB iOS bundle that hurt download conversion, Baidu APP launched a comprehensive size‑optimization project—covering compiler flags, image and resource slimming, code deduplication, and build‑architecture upgrades—that trimmed 50 MB (≈12 %) of the package, boosted conversion rates, and set a benchmark for industry‑wide iOS app size management.
This article examines why Baidu's super‑app needed a drastic reduction in its iOS package size, outlines the metrics that link bundle size to download conversion, compares the app‑size footprints of major domestic and overseas apps, and details the multi‑layered technical solutions—resource trimming, architecture safeguards, compiler tweaks, image compression, and code slimming—that together saved over 50 MB while preserving functionality.
This article presents practical methods for reducing iOS app bundle size by detecting and removing unused Objective‑C/Swift classes, redundant resources, and applying binary optimizations such as segment migration and link‑time optimization, illustrated with real‑world experience from 58.com.
This article details JD's Android app package‑size reduction journey, covering component analysis with APK Analyzer and zipinfo, dependency mapping via Gradle, a suite of slimming measures such as plugin‑to‑download, resource compression, R8, 7‑zip, and a systematic governance framework that ties component growth to enforceable size‑control policies, ultimately achieving over 30% reduction in APK size.
