How to build opencv from source for android studio on windows?

I have to to build opencv from source due to opencv_contrib. Although I have tried many tutorials, I faild to build opencv from source.
The code I used:
cmake -G"MinGW Makefiles" -DANDROID_NDK=D:/androidNDK/android-ndk-r22b -DANDROID_SDK_ROOT=D:/android-sdk -DCMAKE_TOOLCHAIN_FILE=D:/androidNDK/android-ndk-r22b/build/cmake/android.toolchain.cmake -DBUILD_EXAMPLES=OFF -DBUILD_TESTS=OFF -DBUILD_PERF_TESTS=OFF D:/OpenCV455/opencv-4.5.5

How to fix it?
I try to find solutions for similar problem, and here maybe the only similar one. The developer suggetsted that:
Android SDK: not used, projects are not built
After that message Java-based projects should be skipped completely.
Try to upgrade your Android SDK "BuildTools".
CMAKE_CONFIG_GENERATOR="MinGW Makefiles"
There is ninja build tool in Android NDK. Use cmake -GNinja ... for better experience.
I don't quite grasp how to do, My build tools version is 33.0.0.

I found two options:
shell script (reference)
Install Git Bash and set it in PATH (C:\Program Files\Git\cmd)
Install Cmake 3.24.3 and set it in PATH (C:\Program Files\CMake\bin)
Install java and set it in PATH (C:\Program Files\Java\jdk1.8.0_202\bin), create variable JAVA_HOME(C:\Program Files\Java\jdk1.8.0_202)
Install C compiler (mingw or Visual Studio or etc.). If you use mingw, then you will need to install: mingw32-base-bin,
mingw32-gcc-fortran-bin,
mingw32-gcc-g++-bin,
mingw32-gcc-objc-bin,
msys-base-bin. And then in PATH add C:\MinGW\bin
You may also need WSL for Windows, but I did it just through Git Bash
Create a script in an empty folder and name it build.sh:
#!/bin/bash -e
myRepo=$(pwd)
CMAKE_GENERATOR_OPTIONS=-G"Visual Studio 17 2022"
#CMAKE_GENERATOR_OPTIONS=-G"Visual Studio 15 2017 Win64"
#CMAKE_GENERATOR_OPTIONS=(-G"Visual Studio 16 2019" -A x64) # CMake 3.14+ is required
if [ ! -d "$myRepo/gstreamer" ]; then
echo "cloning gstreamer"
git clone https://github.com/GStreamer/gstreamer.git
else
cd gstreamer
git pull --rebase
cd ..

if [ ! -d "$myRepo/openexr" ]; then
echo "cloning openexr"

else
cd openexr
git pull --rebase

if [ ! -d "$myRepo/tesseract" ]; then

cmake --build . --config debug
echo "************************* $Source_DIR -->release"
cmake --build . --config release
cmake --build . --target install --config release
cmake --build . --target install --config debug
popd
Open Git Bash, open the folder with our script in it and write bash build.sh
If you have following error syntax error: unexpected end of file, then here is the solution
As result we get opencv_java460.dll and opencv-460.jar
Cmake with ninja (taken from here, but modified)
Here I will describe what I used to build (it's not a fact that this is all I need or specific versions, but it worked for me):
Install Python and set it in PATH (C:\Users\volce\AppData\Local\Programs\Python\Python311\Scripts\ и C:\Users\volce\AppData\Local\Programs\Python\Python311\)
Install java 8 and set it in PATH and in JAVA_HOME (see above)
Install Cmake 3.24.3 (I haven't tried it on another version) and set it in PATH (see above)
Download NDK r25, unzip and add an environment variable ANDROID_NDK: C:\Users\volce\AppData\Local\Android\Sdk\ndk\android-ndk-r25b
Download SDK tools r25.2.3, platform-tools r25.0.1 and build-tools r25.0.1
In the SDK folder, replace the contents of the tools, build-tools and platform-tools folders with the downloaded ones
Also, in PATH I added: C:\Users\volce\AppData\Local\Android\Sdk\tools and C:\Users\volce\AppData\Local\Android\Sdk\platform-tools
Adding environment variables: ANDROID_HOME and ANDROID_SDK_ROOT, where we specify the path to the SDK (for example, C:\Users\volce\AppData\Local\Android\Sdk)
Download ant and set it in PATH (C:\apache-ant-1.10.12\bin и C:\apache-ant-1.10.12\lib) and create ANT_HOME (C:\apache-ant-1.10.12)
Download MinGw, install the necessary packages and set it in PATH (see above)
Download and install Visual Studio
What did I do next
Created a folder for our task
In it we do git clone https://github.com/opencv/opencv.git and git clone https://github.com/opencv/opencv_contrib.git
In the folder with opencv, go to samples\android and in the file CMakeLists.txt deleting add_subdirectory(15-puzzle) (because of this, I did not build)
Create a build folder in our root folder (which was created for building opencv)
We go into it and do git clone https://github.com/ninja-build/ninja.git
Open Visual Studio. In it: Tools->Command Line->Developer Command Line. In the command line, write the path to the created folder build and write python configure.py --bootstrap. This is how we configured ninja
Being in our build folder in the console, we write the following(don't forget to change the paths to your own):
cmake -GNinja -DCMAKE_MAKE_PROGRAM=E:\OpenCV\build\ninja.exe -DCMAKE_INSTALL_PREFIX=E:\OpenCV\install -DANDROID_PROJECTS_BUILD_TYPE="ANT" -DBUILD_ANDROID_PROJECTS=ON -DBUILD_EXAMPLES:BOOL=OFF -DBUILD_TESTS:BOOL=OFF -DBUILD_PERF_TESTS:BOOL=OFF -DBUILD_JAVA=ON -DBUILD_opencv_java=ON -DBUILD_SHARED_LIBS:BOOL=OFF -DBUILD_FAT_JAVA_LIB=ON -DBUILD_PYTHON:BOOL=OFF -DINSTALL_ANDROID_EXAMPLES:BOOL=OFF -DANDROID_EXAMPLES_WITH_LIBS:BOOL=OFF -DBUILD_DOCS:BOOL=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, armeabi-v7a, x86_64, x86' -DANDROID_NDK_HOST_X64=ON -DBUILD_opencv_python3:BOOL=OFF -DBUILD_opencv_python2:BOOL=OFF -DOPENCV_EXTRA_MODULES_PATH=E:/OpenCV/opencv_contrib/modules -DOPENCV_ENABLE_NONFREE=ON -DANDROID_NATIVE_API_LEVEL=25 -DANDROID_TARGET_SDK_VERSION=32 -DANDROID_MIN_SDK_VERSION=21 E:\OpenCV\opencv
After execution , write ninja -j8 in console
After waiting for the execution of the previous command, we write ninja install
As result we get the OpenCV SDK for Android

Please help me to solve this error!
Here is my packages installed :
qt-opensource-windows-x86-android-5.8.0
JDK.7.Update.80.x64
apache-ant-1.10.1-bin
Android-NDK32-r10-windows-x86_64
Android.SDK.Release.v24.4.1.Windowsinstaller_r24.4.1-windows
what is '-fstack-protector-strong' ?
I think this prevents Qt Creator from continuing !

This problem was because of my android NDK, it was a little old.
I removed Android-NDK32-r10-windows-x86_64 and installed Android-NDK32-r14-windows-x86_64 and now it works fine.

Using buildozer with Kivy 1.9.1-dev

I want to contribute to Kivy 1.9.1-dev.
Trying to debug on android, using buildozer, from ~/ I've tried:
git clone git://github.com/kivy/kivy.git
cd kivy
python setup.py build_ext --inplace -f
then from ~/ I did:
git clone https://github.com/kivy/buildozer.git
cd buildozer
sudo python2.7 setup.py install
finally from ~/kivy-test/
buildozer init
buildozer android debug deploy run
eventually I get the following error:

Any suggestions?

Buildozer can't compile Cython

I am trying to build my kivy application, but having run buildozer android debug --verbose the only I get is following:

How can I make it work?

This is an issue with the Cython version 0.21 and old code. The easiest solution is to downgrade Cython to 0.20, which works.
To use the newer Cython, delete the downloaded pyjnius and let buildozer download the most recent version:
rm ~/.buildozer/android/packages/pyjnius-master.zip
But the newer Cython also needs newer Kivy code. In your buildozer.spec, change kivy in the requirements to kivy==master to get the most recent Kivy code.

Android SDK/NDK error with python-for-android/kivy

I'm on Fedora Linux 19, using the latest Android SDK, latest java SDK, and NDK=R9. Using the instructions here, I'm trying to create a python/kivy installation specialized for android, by running the command, ./distribute.sh -m "kivy". It produces the output below. Can anyone tell me what's going wrong here, and what I can do to fix it? Thank you.

In accordance with the above suggestion of downgrading the API and NDK (to 14 and r8c, respectively), I've downgraded the android tools, and the problem seems to have been resolved. Thanks!
