在 ActivityManager.java 的源码页面中，找到声明 native 关键字的函数。在官方的 cs.android.com 上，你可以直接 Ctrl+Click 或点击函数名，系统会提供跳转链接，直接指向 android_util_Process.cpp 中的 JNI 实现。
If you modify the Android framework for custom hardware, relying on public tools is impossible. You can deploy a local OpenGrok instance to index your custom AOSP build. Step 1: Install Dependencies
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。 xref aosp

Navigating the Android Open Source Project (AOSP) can feel overwhelming due to its massive scale. With millions of lines of code spanning thousands of repositories, finding a specific function definition or tracking down a bug requires specialized tools. This is where becomes indispensable. 在 ActivityManager
The real power of these tools becomes clear when tackling complex tasks.
When developers search for "xref aosp", they are typically looking for one of two things: Share it with the community in the comments below
When developers search for "xref aosp," they are typically looking for web-based tools that allow them to:
tab. The giant was tamed, at least until the next nightly build. how to use xref for specific Android debugging, or are you interested in setting up a local AOSP build
is the primary web-based code search and cross-reference tool used by developers to navigate the massive Android Open Source Project (AOSP) codebase . Managing billions of lines of code across thousands of repositories is nearly impossible without indexing. Xref tools solve this by turning raw source code into an interactive, searchable map.
