@patuoynageek @darvincisec can you give suggestions how to resolve this issue. I am trying to add this C module in another project. TIA

In my case fixed this issue by changing the path in add_custom_command in CMakeList.txt

FROM :

add_custom_command( TARGET native-lib
        POST_BUILD
        COMMAND "${ANDROID_TOOLCHAIN_PREFIX}strip" -R .comment -g -S -d --strip-unneeded ${CMAKE_HOME_DIRECTORY}/../../../build/intermediates/cmake/${CMAKE_BUILD_TYPE}/obj/${ANDROID_ABI}/libnative-lib.so
        COMMENT "Stripped native library")

TO :

add_custom_command( TARGET native-lib
        POST_BUILD
        COMMAND "${ANDROID_TOOLCHAIN_PREFIX}strip" -R .comment -g -S -d --strip-unneeded ${CMAKE_HOME_DIRECTORY}/../../../build/intermediates/cxx/${CMAKE_BUILD_TYPE}/6g1o2x5t/obj/${ANDROID_ABI}/libnative-lib.so
        COMMENT "Stripped native library")

[darvincisec]

Explicit strip command is not really required. I introduced it for removing specific sections in the binary, which is an optional step. As part of building the apk, there is a gradle task that will strip all the native libraries.

[erpriyeshpanchal]

@darvincisec so suppose if i remove the above line of codes it will not affect anything? also do i have to write anything in build.gradle or somewhere else for strip all the native libraries if i remove that add_custom_commandcode ?

[darvincisec]

No need to do anything if you remove add_custom_command code

[erpriyeshpanchal]

Okay, Thank you so much @darvincisec, i am seeking one more help from you where all i have to add code to crash the app or finish the app when frida is detected ?

[erpriyeshpanchal]

wherever __android_log_print is called should i add code for crashing the app ?

[darvincisec]

Search for logs containing text "Act now". You can introduce crash code in the place of the logs.
