How can I use the android version of facedetection in android native c++ code?

Is it possible to **directly** invoke the android facedetection api from native c++ code without calling back java api?

I mean, is the c++ header file of the libmnnfacedetection.so public available?

since I could get the camera stream in android native c++, I'd like to invoke the c++ facedetection api from android native code for higher performance interactive exprience. What can I do to achieve that? Help..please.

Start by checking the Android native C++ integration points and whether a public C++ header is shipped with libmnnfacedetection.so. Review how the camera stream is obtained in native code and look for documented FaceDetection entry points. Done means establishing and documenting a supported direct native path, or clearly confirming that Java invocation is required.
