Debugging C++/native library modules not working with Android Studio (Cmake used)

Question

I\'m having trouble debugging C++ files of my library module.

Is this possible in general?

The debugging works fine if the application project contains the c++ c

Answer 1

I had the similar issue with my own libraries some months ago because I thought that if I added the -g (gcc) flag it would generate the debug symbols, as the desktop (linux, unix kernel) apps.

But, actually it does not work to generate debug symbols.

I see that you use Cmake as a external build tool and clang compiler.

So in my case I configure my cmake script with gcc but out of gradle scripting, but I think it will be the same, I add -mapcs-frame in the CMAKE_CXX_FLAGS.

externalNativeBuild {
        cmake {
            arguments "-DANDROID_PLATFORM_LEVEL=${11}",
                    '-DANDROID_TOOLCHAIN=gcc', 
                    '-DANDROID_STL=gnustl_static',
                    'DCMAKE_CXX_FLAGS=-mapcs-frame'
        }
    }

I know that if you use clang compile may be this flag could not work. But my idea was to share my experience with android native debugging.

I Hope this clues could help you.

Cheers.
