标准回答

This guide covers Android startup, rendering, concurrency, memory, and system performance. It connects application behavior with Framework services, the runtime, and the Linux kernel. Perfetto traces help identify where a critical path spends time and which dependency prevents progress.

A useful case report states the scenario, metric definitions, observations, changes, and validation results. It also records device and software versions, resource costs, and unresolved questions. These details make the conclusion easier to reproduce and review.

中文说明：第一段交代技术范围，第二段说明案例记录的必要内容。critical path 指关键路径，observations 指已观察到的现象，validation results 指验证结果。

Scenario, metric and observation

A scenario describes the user operation. A metric defines what is measured. An observation records what the available data shows. 三者分别对应场景、测量口径和已观察到的事实。
