Hello everyone I am building OpenCV for Android with opencv_conitrb. I am using the following cmake:

cmake -GNinja -DCMAKE_MAKE_PROGRAM=c:/ninja/ninja -DCMAKE_INSTALL_PREFIX=E:/OpenCVAndroidSdk -DANDROID_PROJECTS_BUILD_TYPE="ANT" -DBUILD_ANDROID_PROJECTS=ON -DBUILD_EXAMPLES=OFF -DBUILD_TESTS=OFF -DBUILD_PERF_TESTS=OFF -DBUILD_JAVA=ON -DBUILD_opencv_java=ON -DBUILD_SHARED_LIBS=OFF -DBUILD_FAT_JAVA_LIB=ON -DBUILD_PYTHON=OFF -DINSTALL_ANDROID_EXAMPLES=OFF -DANDROID_EXAMPLES_WITH_LIBS=OFF -DBUILD_DOCS=OFF -DWITH_OPENCL=ON -DANDROID_NDK_HOST_X64=ON  -DANDROID_NDK=C:/Users/volce/AppData/Local/Android/Sdk/ndk/android-ndk-r25b/   -DANDROID_SDK=C:/Users/volce/AppData/Local/Android/Sdk -DCMAKE_TOOLCHAIN_FILE=C:/Users/volce/AppData/Local/Android/Sdk/ndk/android-ndk-r25b/build/cmake/android.toolchain.cmake -DANDROID_TOOLCHAIN=clang -DANDROID_STL=c++_static -DANDROID_ARM_NEON=ON -DANDROID_ABI=arm64-v8a -DANDROID_ABI=x86_64 -DANDROID_ABI=x86 -DANDROID_ABI=arm64-v8a -DANDROID_NDK_HOST_X64=ON -D BUILD_opencv_python3=OFF -D BUILD_opencv_python2=OFF  -D OPENCV_EXTRA_MODULES_PATH=E:/OpenCV/opencv_contrib-4.6.0/modules -DOPENCV_ENABLE_NONFREE=ON -DANDROID_NATIVE_API_LEVEL=21 -DANDROID_SDK_TARGET=30  ..

But cmake can’t find java and ant:

I get the following error:

BUILD FAILED
C:\Users\volce\AppData\Local\Android\Sdk\tools\ant\build.xml:649: The following error occurred while executing this line:
C:\Users\volce\AppData\Local\Android\Sdk\tools\ant\build.xml:655: null returned: -1073741819

I have switched to sdk tool 25.2, sdk platform tools 25, java 8

4

sdk tool 25.2, sdk platform tools 25, java 8, Does it work？

So what’s the solution?
