# This shell script is to set up ASAN for debugging native libs.
# Specify your own path in those variables below.

# They have to be adjusted to your environment and NDK version.
# Although note that whenever we use AAP the NDK version has to be fixed to
# this one otherwise libc++_shared.so version mismatch may bite you.
#
# Also note that you need below in build.gradle:
# > android.packagingOptions.jniLibs.useLegacyPackaging = true
