Practical Performance Tuning on Android
summary
Practical Android performance tuning for a healthcare app: measured CPU, memory, network and rendering with Android Profiler and Layout Inspector to identify deep view hierarchies and 4× overdraw. Fixes included flattening layouts and removing backgrounds to reduce GPU time, reusing thread pools to avoid thread-creation overhead, adding disk/memory caches and switching JSON to protocol buffers to shrink payloads, using WebP for images (≈24–35% savings), and batching work with WorkManager to reduce network and battery use.
