High performance in Android
summary
Lists concrete limits and tools: UI must hit 0.1s / 1s / 10s limits to avoid jank or ANRs; use Traceview and DDMS (allocation tracker, network tagging, heap viewer) plus Hierarchy Viewer and GPU rendering to find slow frames. Remove default window background, use merge/include/ViewStub to cut layout depth; prefer @IntDef over enums for smaller dex, avoid static Views and cancel async subscriptions to prevent memory leaks; batch/prefetch network calls, respect connectivity classes, and use exponential backoff to save battery.
