: While Google's Code Search is the standard, some developers still use community-hosted mirrors like AOSPXRef for specific legacy views or custom indexing. Who Is This For? Source control tools
Here is a breakdown of the best free ways to cross-reference AOSP online today. 1. Google’s Official Android Code Search (android.com)

Even with free tools, mistakes happen. Here is what to avoid:
codebase requires specialized tools to navigate millions of lines of code. While several "xref" (cross-reference) sites have historically served this need, the landscape has shifted toward official and community-maintained alternatives. 🛠️ Top AOSP Cross-Reference Tools
This is where the "xref" component comes into play. In software development, a cross-reference tool allows developers to search for definitions and usages of functions, variables, and classes instantly. Unlike a simple text search, a cross-reference tool understands the structure of the code. If a developer wants to know where the Activity class is initialized, an xref tool will list every file in the repository where that class is referenced. Historically, OpenGrok has been a popular tool for this purpose, but the specific search query "xref aosp" often directs users to a streamlined, web-based interface often hosted at domains like cs.android.com or independent mirrors specifically optimized for AOSP.
