1.ensure you ndk is set into environment.
2.run ndk-stack to analyze logcat and symbol file to find where crash printed.
//gradlew build with ndkBuild:
adb logcat | ndk-stack -sym ./aesjni/build/intermediates/ndkBuild/debug/obj/local/arm64-v8a/objs-debug/
//gradlew build with CMake:
adb logcat | ndk-stack -sym ./aesjni/build/intermediates/cmake/debug/obj/arm64-v8a
//if you run ndk-build command:
adb logcat | ndk-stack -sym ./aesjni/src/main/obj/local/x86/
../obj/local/x86/ and ../obj/local/armeabi-v7a/ is symbol file directory.
I got crash logs:
