: While in the createBitmap() method, you'll see it calls other functions, like a native method nativeCreate() . By clicking on nativeCreate() , the XREF tool can take you to its JNI (Java Native Interface) implementation, likely in a .cpp file, and from there, you can continue tracing the code into the C++ layers of the Android Framework.

Instantaneous search, deeply integrated cross-references, includes Git history, supports dark mode, and indexes sub-projects like Jetpack, Fuchsia, and the Linux Kernel.
You are debugging an issue related to how Android creates a Bitmap object and want to find all the code that might be involved. : While in the createBitmap() method, you'll see
Companies like Sourcegraph, Understand, and Scitools offer incredible AOSP xref capabilities, but they come with licensing fees (often $500–$2,000 per user/year). While Google’s internal cs.android.com is free, it has limitations: it lacks deep call hierarchy for native code, has rate limits, and requires constant internet access. For offline work or deep static analysis, you need an alternative.
If you need to quickly track down a specific class definition or hardware abstraction layer (HAL) interface, web-based indexing tools provide immediate value. Below are the premier free platforms currently available: Google’s Official Android Code Search ( cs.android.com ) mkdir aosp-source && cd aosp-source repo init -u
Powered by Google’s open-source Kythe semantic indexer, this tool understands the abstract syntax tree (AST) of the compilation graph.
