I am trying to build OpenCV as part of an AOSP 13 build. I cloned OpenCV and integrated it into AOSP using an Android.bp file. However, I keep encountering errors related to missing headers and undeclared identifiers during the build process.

Steps Taken:

1. Cloned OpenCV into external/opencv. cmake -DCMAKE_TOOLCHAIN_FILE=/android-ndk-r21e/build/cmake/android.toolchain.cmake -DANDROID_ABI=arm64-v8a -DANDROID_STL=c++_shared -DANDROID_NATIVE_API_LEVEL=33

2. Created an Android.bp file to build OpenCV as part of AOSP. And I think problem is with the Android.bp

   cc_library_shared {
       name: "libopencv_core",
       srcs: [
           "modules/core/src/**/*.cpp",
           "modules/imgproc/src/**/*.cpp",
           "modules/highgui/src/**/*.cpp",
           "modules/calib3d/src/**/*.cpp",
       ],
   exclude_srcs: [
       "modules/highgui/src/backend_*.cpp",
       "modules/core/include/opencv2/core/private.hpp",
       "modules/core/include/opencv2/core/private.cuda.hpp",
       "external/opencv/modules/core/include/opencv2/core/private.cuda.hpp",
       "external/opencv/modules/core/include/opencv2/core/private.hpp",
   ],
   export_include_dirs: [
       "modules",
       "include",
       "modules/core/include",
       "modules/imgproc/include",
       "modules/highgui/include",
       "modules/calib3d/include",
       "build",
       "include",  
   ],
   cflags: [
       "-DANDROID",
       "-DOPENCV_ANDROID",
       "-fexceptions",
       "-frtti",               
       "-DHAVE_OPENCL=0",     
       "-DOPENCV_DISABLE_TRACING", 
       "-DNO_OPENCL",
   ],
   shared_libs: [
       "liblog",
       "libandroid",
       "libmediandk",
       "libjpeg",
       "libpng",
       "libz", 
   ],
   static_libs: [
       "libc++_static",
       "liblog",
   ],
   stl: "c++_shared",
   rtti: true,  
   strip: {
       none: true,
       },
   }
   

So is my Android.bp file correctly set up for OpenCV in AOSP? Does OpenCV require additional configuration to work with AOSP's build system?
