<span class="abstract-title-text">耗时大半年，开源一本 Android 电子书《Android 技术内幕：系统机制、性能优化与工具实战》</span>
</a>
<div class="abstract-content">
<p>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。</p>
<p>AIW 想补的就是这个缺口。全称 Android Internal Wiki，中文书名是《Android 技术内幕：系统机制、性能优化与工具实战》，五部分二十六章，正文钉在 Android 17。仓库现已公开：</p>
<p><a target="_blank" rel="noopener" href="https://github.com/Gracker/android-internals-wiki">https://github.com/Gracker/android-internals-wiki</a></p>
<p>打开仓库能拿到的是二十六章正文、一份完整目录，和每周编一次的 EPUB。</p>
<p>这二十六章现在到了可以拿出来给人读的程度。读到哪一段和源码对不上，欢迎提 issue 或者 PR。</p>

<span class="abstract-title-text">Android Perfetto 系列 18：响应速度实战，从输入事件到首帧反馈</span>
</a>
<div class="abstract-content">
<p>按钮按下后，按压态何时出现？滑动列表时，内容何时第一次跟着手指移动？这两个问题都要找到输入事件和对应的第一帧反馈；启动总耗时与后续动画帧率回答的是别的问题。</p>
<p>本文用 Perfetto 把 InputReader 读到事件、InputDispatcher 派发、App 处理、帧提交和 SurfaceFlinger 呈现分开计时。每一步的起止点要能回到 Trace 核对。</p>
<p>从 InputReader 的 <code>read_time</code> 到关联帧 present，可以得到系统内部延迟的候选值 <code>estimated_input_to_present_ms</code>。只有确认目标 layer、业务状态确实在那一帧发生视觉变化，才把它写成 <code>input_to_present_ms</code>。这段时间不包含触控 IC、驱动上报前延迟、显示扫描和面板响应。</p>
<p>点击和滑动还需要不同的终点定义：按压态、转场首帧和内容第一次位移不能混成一个数。App marker 能说明业务动作，高速相机可补外部可见时点。</p>

<p>这里用 Camera 和 Audio 两个场景说明：先确认一次操作涉及哪些进程和线程，再按阶段或真实周期计算耗时，最后把异常时间点、来源轨道和质量限制写进报告。平台侧还要维护稳定的事件名和采集配置，下一次 Trace 才能复用查询。</p>

<p><code>dumpsys meminfo</code> 显示进程内存上涨，Java heap dump 却没有对应的对象增长时，下一步先查上涨落在 Native Heap、图形 Buffer，还是其他映射。若可疑部分来自 malloc/new，heapprofd 可以把分配与调用栈对应起来。</p>
<p>heapprofd 的分配、释放和调用栈记录能与业务事件放在同一条 Perfetto 时间轴上，便于核对一次操作前后哪些分配仍未释放。</p>
<p>heapprofd 是采样工具，看到的 native allocation 不能直接当作 RSS，也不覆盖 Java 对象引用或所有图形 backing 内存。先分清内存账，再决定是否抓 profile。我更倾向先用 meminfo 和 smaps 把上涨来源拆开，再打开 flamegraph；若涨的是 GraphicBuffer，盯着 malloc 调用栈改代码就找错了方向。</p>

<span class="abstract-title-text">Android Perfetto 系列 11：PerfettoSQL、Trace Processor 与回归检测</span>
</a>
<div class="abstract-content">
<p>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，还能不能算出可复查的数字。</p>
<p>PerfettoSQL 与 Trace Processor 可以把时间窗口、线程身份和耗时口径写进查询，再让 Python 对多份 Trace 执行同一段 SQL。这样复测版本时，能回到每份原始 Trace 核对数字。</p>
<p>下面从一条手工判断出发，逐步得到可批量执行的查询和结构化输出。示例代码需要替换目标进程、时间窗口和采集条件后再用于自己的场景。</p>

<span class="abstract-title-text">SmartPerfetto 开源：面向 Android Trace 分析的 Perfetto AI Assistant</span>
</a>
<div class="abstract-content">
<p>SmartPerfetto 已经完整开源。打开仓库能看到当前可运行的主干工程：Perfetto UI fork、后端 agentv3、MCP 工具、YAML Skill、场景策略、脚本和文档。没有保留私有核心模块，也没有只放一层 demo 壳。</p>
<p>这个项目来自一个很具体的日常场景：手里有一条 trace，Perfetto 已经把事实摆出来，但从事实到判断还要翻表、写 SQL、对线程、看 FrameTimeline、找 Binder 对端，再回到时间线上确认一遍。SmartPerfetto 想把这些重复动作固化成工具，让性能工程师把时间花在判断上。</p>
<p>它还处在开发阶段。现在放出来，是因为 trace 分析靠真实样本长出来：真实设备、真实厂商差异、真实业务 trace、真实 PR，都会改变 Skill 和策略该怎么写。等所有能力都稳定后再单向发布，反而会错过最需要样本的阶段。</p>
<p>如果你日常会打开 Perfetto 看滑动卡顿、启动、ANR、Binder、CPU 调度或渲染管线，SmartPerfetto 提供的是一个带 AI Assistant 的 Perfetto UI：加载 trace 后，用自然语言提问，后端查询 <code>trace_processor_shell</code>、调用 YAML Skill、组织证据，再把结论和数据表格流式显示在浏览器里。</p>
<p>项目地址：</p>
<ul>
<li>主仓库：<a target="_blank" rel="noopener" href="https://github.com/Gracker/SmartPerfetto">https://github.com/Gracker/SmartPerfetto</a></li>
<li>Perfetto UI fork：<a target="_blank" rel="noopener" href="https://github.com/Gracker/perfetto">https://github.com/Gracker/perfetto</a></li>
</ul>
<p>普通试用只需要看主仓库。<code>Gracker/perfetto</code> 是 <code>perfetto/</code> submodule 对应的前端 fork，主要给需要改 AI Assistant 插件 UI 的开发者使用。</p>
<p>前两篇技术文档更适合想看工程细节的读者：</p>

</ul>
<p>前两篇把内部架构讲得比较细，但源码放出来以后，读者更关心的是仓库里到底有什么、能不能跑、哪些地方还没稳。这篇主要补开源这件事：开放了什么、当前能做什么、内部怎么分工、怎样在本地跑起来、哪些地方适合一起改。</p>

<span class="abstract-title-text">万字长文推演：手机不再从 App 开始，Agent OS 如何接管任务入口</span>
</a>
<div class="abstract-content">
<blockquote>
<p>以 2026 年 4 月 27 日郭明錤关于 OpenAI 手机的产业链消息为起点，从 Android 手机从业者视角，推演手机与 AI 融合之后的系统形态。</p>
</blockquote>
<h2><a href="/2026/04/28/Agent-OS-Task-Entry/#引言：这不是一台新手机的问题" class="headerlink" title="引言：这不是一台新手机的问题"></a>引言：这不是一台新手机的问题</h2><p>郭明錤这条消息最值得关注的地方，不在 2028 年量产这个时间点，也不在联发科、Qualcomm、立讯分别处在什么供应位置。</p>
<p>它把问题推到了系统层：</p>
<p>如果用户的主要目的从打开 App 转向完成任务，手机操作系统应该长什么样？</p>
<p>这句话听起来像 UI 变化，但站在 Android 从业者视角，它牵动的是一整套系统结构：Launcher、通知、权限、IPC、App 能力声明、模型运行时、TEE、端云同步、任务状态机、审计记录、支付确认、开发者分成，都会被重新审视。</p>
<p>过去几年，AI 手机的讨论大多停在功能层。厂商讲 AI 修图、AI 消除、AI 摘要、AI 搜索、AI 助手、AI 简报，这些都能放进现有 Android 或 iOS 架构里。</p>
<p>OpenAI 如果真的按 AI Agent 手机去做，它会把问题从“手机里还能塞多少 AI 功能”，推到“手机的第一入口还要不要从 App icon 开始”。</p>
<p>主线是：Agent OS 更像移动 OS 在图形界面之后的一次结构迁移。前台从 App 网格迁移到任务流，后台从 App 独占能力转为可授权能力，系统从管理进程和窗口转向管理任务、上下文与责任。</p>
<p>OpenAI 做手机不一定基于 Android，但概率很高，因为它能继承硬件适配、驱动、应用兼容和供应链经验。但如果 OpenAI 想完全按 Agent OS 设计第一屏、权限和任务流，它也可能走一条“Android 兼容但不完全是 Android”的路，甚至用 Linux 自建系统，再用 Web、云端执行和应用兼容层补齐服务。</p>
<p>不同 OS 选择会改变进入市场的速度，却不会改变 Agent OS 必须解决的五件事：</p>
<ol>
<li>手机要持续理解用户的当前状态。</li>
<li>App 要从前台入口变成后台能力提供者。</li>
<li>系统要有可恢复、可取消、可审计的任务运行时。</li>
<li>端侧与云端要按数据敏感度和实时性分工。</li>
<li>所有跨 App、跨设备、跨云的执行都要有权限、责任和回滚边界。</li>
</ol>
<p>这五件事没有完成，AI 手机就只是“手机里装了一个 AI 助手”；它们一旦形成系统约束，手机才会朝 Agent OS 走。</p>
