What the file says
## 面试官在意什么 Android 工程师的日常是在 Kotlin 与 Jetpack 体系里写业务页面与架构层：Activity/Fragment 或 Compose 页面、ViewModel 与状态流、协程管理异步、Room/DataStore 存储、Hilt 注入、Gradle 多模块构建、适配从 Android 8 到最新版本以及各家厂商 ROM 的差异。真实面试里 Android 题的分水岭在"系统为什么这样设计"：能背出生命周期回调顺序的人很多，能解释配置变更时 ViewModel 为什么能活下来、Fragment 的 viewLifecycleOwner 为什么存在、协程作用域为什么和生命周期绑定的人少。面试官最在意三件事：一是对系统机制的真实理解（生命周期与进程、消息循环与主线程、Binder 与四大组件、ART 与内存），二是协程与 Compose 这两套新范式的心智模型是否正确（结构化并发、异常传播、重组与稳定性），三是线上问题的排查闭环（ANR、OOM、卡顿、启动、包体各自的工具与归因方法）。 校招侧重四大组件、生命周期、Handler 机制、View 绘制与事件分发、Kotlin 语言特性、协程基本用法与 RecyclerView；社招侧重架构分层与模块化、Compose 落地经验与性能坑、协程异常与取消的工程实践、启动与包体的量化治理、ANR 与 OOM 的归因、Gradle 构建提速、以及厂商 ROM 与新版本适配的踩坑。一线大厂通常还有"手撕算法 + 系统原理 + 项目深挖"的固定结构，这个包负责系统原理与项目深挖里的 Android 特有部分。 怎么问才像这个方向的面试官： - 每个系统机制题都追"系统为什么这么设计"：生命周期、Handler、Binder、后台限制，能背回调但说不出设计动机的要标记。 - 协程与 Compose 是当前最能区分深度的两块：题目从"异常把兄弟协程取消了""不该重组的组件重组了"这类真实 bug 切入，让候选人解释模型。 - 性能题必须落到工具与数字：Perfetto、Layout Inspector、Profiler、build scan 的实际使用经验是社招硬门槛，只说"放子线程""减少嵌套"的要追工具。 - 不考版本时效：不问"Android 15 新增了什么 API"，考的是行为变更的排查方法与兼容思路；平台无关的启动、包体、灰度、跨端题交给 parent 包 mobile。 ## 项目 / 实习怎么深挖 简历上出现下面这类经历时从哪里切、追什么。追到候选人能说出机制、数字的来源与一次真实的故障或取舍才算实；只有框架名与结论、说不出自己那一段的，记为危险信号。通用的追问方法见 project-deep-dive。 …

How to install
mdr add yuecao365/offercome/android@git:20260920.a4843f5mdr add yuecao365/offercome/android@sha256:59ab8a405d3d162dPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
