Xref Aosp

file: Filters results by file path (e.g., file:core/java/ to look only inside core framework Java files).

Replace /path/to/your/aosp/source with your actual source directory and adjust the port mapping as needed.

In software engineering, a tool indexes a codebase to show exactly where variables, macros, functions, and classes are defined, and where else they are called or modified throughout the project.

Android Code Search excels at comparing code across branches. When investigating whether a particular behavior changed between Android 12 and Android 13, you can switch branches directly in the interface, then visually compare the same file across different versions. This capability is invaluable for determining if an observed bug is specific to your current platform version or exists upstream. xref aosp

It is slow for deep dives. If you need to work offline, or if you are integrating navigation into an IDE (VS Code, Android Studio, or Vim), you need a local solution.

When developers search for "xref aosp," they are typically looking for web-based tools that allow them to:

And it is beautiful. Because xref AOSP proves that despite the polished glass and aluminum slabs in our pockets, the machine running the show is still a scrappy, messy, open bazaar of logic. It is the closest thing we have to a soul for the smartphone—one line of cross-referenced C++ at a time. file: Filters results by file path (e

xref aosp is a command commonly used within the Android Open Source Project (AOSP) development environment. The xref tool is utilized for searching within the AOSP source code. When you run xref aosp , you're essentially asking the tool to provide a cross-reference of where a particular term, usually a function, variable, or a specific string, is used across the AOSP codebase.

sudo docker run --rm -d \ --name "opengrok" \ -v /path/to/your/aosp/source:/src \ -v /path/to/opengrok/data:/data \ -p 9092:8080 \ scue/docker-opengrok:latest

The initial indexing will take significant time—potentially several hours for a full AOSP checkout. Once complete, access your private XRef server at http://<your-ip>:9092/source/ . Android Code Search excels at comparing code across branches

xref generates a browsable, hyperlinked view of your source code. It parses symbols (functions, classes, variables, macros) and lets you:
