Android high performance baby
summary
Claims concrete gains from techniques like prefetching, connection queuing and exponential backoff, and shows that careful networking and caching cut mobile bandwidth and perceived wait. Uses Android tools: systrace and Traceview, DDMS allocation tracker, network stats and GPU rendering overlay to find 16 ms frame bottlenecks and memory leaks. Gives concrete rules: responsiveness thresholds 0.1s 1s 10s, ANR at 5s, broadcast receivers 10s. Recommends patterns that compile and run: @IntDef, StringBuilder, ViewStub, IntentService, Loaders to reduce allocations and leaks.
