If you are currently working on a specific debugging or reverse-engineering task, tell me you are trying to locate, and I can help you construct the exact query or guide you through its typical architecture.
以 为代表的第一代在线工具改变了游戏规则。基于 OpenGrok 引擎 构建，开发者第一次可以通过浏览器无痛地查阅 AOSP 源码，并支持基础的代码跳转（如点击函数名跳转至定义）。然而，这一时期的工具反应较慢（约 500-1000ms），且主要支持到 Android 9，更新速度略显迟滞。
For example, to locate the Activity class definition, you could use the Definition search with "Activity," optionally restricting the path to "frameworks/base" to narrow results.
The narrative of cross-referencing in AOSP is therefore a narrative about attention and trust. Effective xref tools reduce cognitive friction: they let you follow a function from system service through Binder IPC into native libraries, trace an API’s evolution across branches, and locate the exact device overlay that turns generic behavior into a handset’s unique fingerprint. That traceability turns anxiety about change into a scaffold for deliberate action. You can refactor with a map in hand, confidently remove dead code, or submit a security patch knowing where the touchpoints lie. xref aosp
如果你使用的是 AOSPXRef 或 AndroidXRef，以下 OpenGrok 搜索语法能极大地提高工作效率：
But here is the eerie part: The xref reveals the ghosts . Scroll back far enough in the history, and you’ll find code written by engineers who have since left Google. You’ll find FIXME comments from 2012 about devices that have been recycled into soda cans. You’ll find the remnants of “Project Fuchsia” experiments hidden behind #ifdef statements.
Instantly find every file that calls a specific function. If you are currently working on a specific

Use xref to answer: "Which modules depend on libaudioclient ?" In cs.android.com, click the module name to see reverse dependencies.
