Cmake link wrong path of a pre built binary android

Question

I'm trying to add python on my android app using PyBridge . I compiled libpython3.8.so using python-for-android Docker container for ABI arm64-v8a armeabi-v7a with no error. I successfully build a test apk using cmake for native library.

But when i run app on my phone I got this error

2022-01-29 14:09:42.066 23611-23611/com.manob.pythontest E/AndroidRuntime: FATAL EXCEPTION: main

In errorlog I find path of libpython3.8.so /Users/manobbiswas/AndroidStudioProjects/PythonTest/app/src/main/cpp/../libs/arm64-v8a/libpython3.8.so instade of /lib/arm64/libpython3.8.so

hear is CmakeList.txt

cmake_minimum_required(VERSION 3.10.2)
project("pythontest")
add_library(
        pythontest
        SHARED
        native-lib.cpp)

add_library(python3.8
        SHARED
        IMPORTED)

set_target_properties(python3.8
        PROPERTIES IMPORTED_LOCATION
        ${PROJECT_SOURCE_DIR}/../libs/${ANDROID_ABI}/libpython3.8.so )

include_directories(include/${ANDROID_ABI})

find_library(log-lib log)

target_link_libraries(pythontest python3.8 ${log-lib})

Answer 1

This error happens caused while building libpython3.8.so SONAME header wasn't set.

It can be verified by

readelf -a libpython3.8.so
