[ZhouGongZaiShi]

The android project references the .so file produced by androidNativeArm32/64. If there is a problem with the native code, the following log will be printed:

Even if I use addr2line I don't get the number of rows.

cd ~/.konan/dependencies/target-toolchain-21-linux-android_arm64/bin/
./aarch64-linux-android-addr2line -fe ~/work_dir/work_code/brotli-project/brotli-kotlin-native/build/bin/arm64/debugShared/libbrotli_kotlin_native.so  000000000003c27c 0000000000028af4 

TerminateWithUnhandledException
:?
Java_dec_DecoderJNITest_nativeCreate
:?

Please tell me how to get the number of rows in the error stack, or other debugging ways?? Thank you!
