10月27日，IDC发布2026年第三季度中国智能智能手机市场跟踪报告。当季出货量约5806万台，同比下降15.2%，较上半年约4%的降幅明显扩大。存储及元器件成本大幅上升引发的终端涨价与配置调整，已开始抑制消费需求。厂商格局方面：华为以2...
一份 Trace 能在 UI 里打开、SQL 也查得到行，仍可能在采集中丢过统计结果。线程状态缺一段、进程名对不上、Track Event 只有 ID 没有名称时，先查统计结果丢在哪一层，再决定哪些分析还能继续。SQL 只能度量留下来的事件...
开机慢、亮屏后偶发卡顿或几小时后才出现的音频断续，通常等不到工程师连上电脑再按「开始录制」。要保留问题发生前的调度、帧或音频事件，采集配置必须提前在设备上运行。现场抓取要先确定触发点前后各保留多久，再选 Ring Buffer、周期写文件或...
Camera 打开慢要区分 API 返回、HAL 首个 Buffer 和预览画面体现；Audio underrun 要看 App 写入与 mixer 周期是否稳定。这些事件分散在 App、系统服务、HAL 和调度轨道里，单列一张 Top s...
在 Perfetto UI 里框出问题窗口，看主线程、RenderThread 和 CPU 状态，再截几张图，单次定位很方便。换一份 Trace 或换一台设备，截图里的判断就难以按同一口径重算。我更关心的是：下次拿到同一类问题，还能不能算出...
平台 Trace 能体现线程、CPU、帧和 Binder 等系统事件；播放器的 frame id、作品 scene 名称或业务队列里的等待时段，需要软件自己提供。缺少这些标记时，一段主线程耗时只能定位到系统活动，难以对应业务阶段。Perfe...
FrameTimeline 标出一帧晚了，主线程和 RenderThread 没有明显长任务，下一步可以查 GPU 工作与 fence。GPU 频率、电池电流和电源轨只能提供同一窗口的硬件状态，不能单独证明某个 App 帧为何晚呈现。这篇把...
这篇文章只做一件事：把我长期维护、正在推进、已经公开和暂未公开的项目集中到一个地方。范围包括 Android 性能分析、Perfetto 工具、AI 自动化、iOS App、Android Demo、测试套件、博客系列、社群和各个平台账号。...
Android 内部机制的资料，网上不缺。AOSP、官方文档、博客、论文、trace 讨论，想找都找得到。麻烦的是各说各的版本：这篇是 Android 12 的结论，那篇没写版本，再一篇是某台机器上的现象。AIW 想补的就是这个缺口。全称 ...
