Unable to build caffe2 AICamera app

Issue

While trying to build AICamera app master branch, we failed to link the required native-lib library.

native-lib.cpp:144: error: undefined reference to 'caffe2::Predictor::run(std::__ndk1::vector<caffe2::Tensor<caffe2::CPUContext>*, std::__ndk1::allocator<caffe2::Tensor<caffe2::CPUContext>*> > const&, std::__ndk1::vector<caffe2::Tensor<caffe2::CPUContext>*, std::__ndk1::allocator<caffe2::Tensor<caffe2::CPUContext>*> >*)'

Please advise

Android studio: 3.1.3

NDK: 17.1.4828580

Solution

So the problem was with Android studio version. The app cant be compiled using it. Switching to 3.0.1 solved the problem. Also, switching to NDK 13b helps with compiling it properly.
