GWP-ASan
Important: GWP-Asan is one of many tools available for memory debugging and mitigation. See Memory error debugging and mitigation for an overview of all the tools.

GWP-ASan is a native memory allocator feature that helps find use-after-free and heap-buffer-overflow bugs. Its informal name is a recursive acronym,"GWP-ASan Will Provide Allocation SANity". Unlike HWASan or Malloc Debug, GWP-ASan does not require source or recompilation (that is, works with prebuilts), and works on both 32- and 64-bit processes (although 32-bit crashes have less debugging information). This topic outlines the actions you need to take to enable this feature in your app. GWP-ASan is available on apps that target Android 11 (API level 30) or higher.
