Android demo is giving issue at compiling

[soham24]

/src/main/cpp/vnnjni.cpp:59: undefined reference to `VNN_Destroy_Face'

/src/main/cpp/vnnjni.cpp:1197: undefined reference to `VNN_Destroy_ObjCount'

./../src/main/cpp/vnnjni.cpp:1313: undefined reference to `VNN_Destroy_DocRect'

Can I know a specific version of the CMake tool and NDK version which is used at the time of compiling demos

[mrbrantofgithub]

cmake: 3.6.4111459, ndk: 21.3.6528147

I am building this on Linux machine / ubuntu

I have uploaded the demo project, (which is getting failed to build) on the above link. this was the error: undefined reference to 'VNN_Destroy_DocRect'

I wonder why is this coming even when all files are properly provided in the path

Sorry! Because of some mistakes, android so files are not newest. Now you can update so files, and try to build again.

[soham24]

@mrbrantofgithub thank you so much for your quick response. it is working fine now. You guys are doing very good work by open-sourcing this. much respect.
