APK Size Optimization Techniques for Game Center Application

Ke Jie explains why reducing the Game Center APK—by eliminating alpha‑PNG images, unused code and resources, limiting language and density assets, disabling v1 signing, compressing images, loading native libraries on demand, shipping only 64‑bit binaries, enabling code/resource shrinking and R‑file inlining—cut size by about 31% (≈20 MB), boosting download conversion and launch performance.
