Hi, check if the build file under prebuilts/clang/host/linux-x86 mentions libclang_rt.asan-i686-android.so It might have not been there yet. If that's the case, you can try to engage in software archaeology and figure out how to build the missing library at the matching version (it needs to be more or less in sync with clang), but that's a long story. The short answer is: Android N is probably too old and does not support asan/x86.
