I'm trying to build POCO for Android (x86) with NetSSL_OpenSSL support which is not enabled by default. This is my configure line:
$ ./configure --config=Android
And this is my cmake line:
$ cmake -H. -B./poco-build-x86 -G'Ninja' -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=/Users/me/Library/Android/android-ndk-r19c/build/cmake/android.toolchain.cmake -DANDROID_NATIVE_API_LEVEL=21 -DANDROID_ABI=x86 -DCMAKE_INSTALL_PREFIX:PATH=install-x86 -DOPENSSL_ROOT_DIR=/Users/me/dev/openssl-1.1.1g/install-x86/ -DOPENSSL_CRYPTO_LIBRARY=/Users/me/dev/openssl-1.1.1g/install-x86/lib -DOPENSSL_INCLUDE_DIR=/Users/me/dev/openssl-1.1.1g/install-x86 -DENABLE_CRYPTO=ON -DENABLE_NETSSL=ON
I'm getting this error at cmake time:

What I'm doing wrong?
The solution for this question was use static libraries from OpenSSL. So, you need to link against .a instead of .so/.dylib. Something like:
cmake -H. -B./poco-build-x86 -G'Ninja' -DCMAKE_BUILD_TYPE=Release -DCMAKE_MAKE_PROGRAM=/Users/juangarcia/Library/Android/sdk/cmake/3.10.2.4988404/bin/ninja -DCMAKE_TOOLCHAIN_FILE=/Users/juangarcia/Library/Android/android-ndk-r19c/build/cmake/android.toolchain.cmake -DCMAKE_C_COMPILER=/Users/juangarcia/Library/Android/android-ndk-r19c/toolchains/llvm/prebuilt/darwin-x86_64/bin/clang -DCMAKE_CXX_COMPILER=/Users/juangarcia/Library/Android/android-ndk-r19c/toolchains/llvm/prebuilt/darwin-x86_64/bin/clang++ -DANDROID_NATIVE_API_LEVEL=24 -DANDROID_ABI=x86 -DOPENSSL_CRYPTO_LIBRARY=/Users/juangarcia/Downloads/openssl_111_android/lib/x86/libcrypto.a -DOPENSSL_SSL_LIBRARY=/Users/juangarcia/Downloads/openssl_111_android/lib/x86/libssl.a -DOPENSSL_USE_STATIC_LIBS=TRUE -DENABLE_NETSSL=TRUE -DOPENSSL_INCLUDE_DIR=/Users/juangarcia/Downloads/openssl_111_android/inc/x86 -DCMAKE_INSTALL_PREFIX=install-x86
You should note that in the command above, I'm setting CMAKE_INSTALL_PREFIX to auto install in a directory, but it is not necessary to solve the question.

Problem Description:
I am trying to compile OpenCV 4.5.1 on Ubuntu 20.04 LTS for Android (aarch64) with OpenCL support (since the stock OpenCV Android SDK does not have OpenCL support activated). I largely followed this tutorial covering the cross-compilation of OpenCV.
When trying to configure the build, Cmake seems to be unable to correctly create/locate all the necessary folders and thus throws an error (see cmake output below).
I suspect that it might have something to do with Cmake struggling to recognise the ant installation correctly (as indicated by the missing version number following the ant path in the Cmake output).
I have set the environment variables for the ANT executable as well as the Java Home folder through the Cmake build flags (see Cmake command below).
When looking at the error messages at the bottom of the Cmake output, it becomes clear that there is some problem with creating the necessary Android and/or Java folders. Upon inspection of modules/java/android_sdk/CMakeLists.txt (see extract below) I noticed that the variable OPENCV_JAVA_DIR should probably be set at some earlier stage in the cmake configuration. However, when running my command pasted below, this variable remains empty and hence cmake cannot access the folders since the path is not correct.
These are the values of the variables when running my cmake configuration command:
-- OPENCV_JAVA_DIR = /opencv
-- ANDROID_EXECUTABLE = FALSE
-- ANDROID_BUILD_BASE_DIR =
-- OpenCV_BINARY_DIR= /home/flavio/Downloads/opencv/build_manual
Is there some configuration error in my Cmake buildflags or something entirely different that I am doing wrong?
Thanks for you help!

I have tried all the proposed changes, so far with no success. Reinstallation of ant did not help, neither creating a symlink to the executable store at /usr/share/ant/bin/ant in /usr/bin.

I had similar errors, so I fixed it by turning on -DBUILD_ANDROID_PROJECTS=ON and fix all incompatible "SDK TOOL version" or "gradle versions". Then gradle can set all necessary paths like ANDROID_BUILD_BASE_DIR in modules/java/android_sdk/CMakeLists.txt:15.
For example to update SDK Tools: Open android studio > setting > system settings > Android SDK > SDK Tools > update Android SDK build tools and NDK(side by side)

I am trying to build an android native project using gradle. While the build passes for the architectures arm64-v8a, x86 and x86_64, it fails for armeabi-v7a with a unique error:

ninja: build stopped: subcommand failed.
The issue here is I am able to run this command and it builds the native libraries successfully when run the machine locally, but it fails when it is run through jenkins. The other amusing thing is that it fails only for the abi armeabi-v7a and passes for all other architectures.
I have verified the user, path and environment variables like ANDROID_HOME and ANDROID_NDK_HOME which are same when I run using the command line on the machine locally and when run using jenkins.
The command was not able to open the output files in the location "/apps/temp" as this directory was not present in the slave. This temp directory present in the jenkins master and was passed to the slave which was visible in the build variable TMP_DIR. Explicitly mentioning a valid temporary directory for the jenkins slave fixed the issue.
I have tried several days installing the NDK into Android Studio but it always gives me an error message saying that the build failed and I should install a c compiler. I installed the NDK via the SDK Manager by checking the NDK and C Make.
I have already tried completely reinstalling Android Studio and the NDK but that did not work as well -same error.
Something maybe worth mentioning is that if I do not check the C++ support during the project creation there are no errors(but no c++ support too:D).
What should I do because it kills my workflow?
Thank you very much

I cloned a project from a github repository and opened it in my Android Studio 3.0.
As soon as I open up Android Studio I get an Error:
Cannot load module file 'C:\Users\David Ferrara\AndroidStudioProjects\ClBooking-master\Bookingtest.iml':
File C:\Users\David Ferrara\AndroidStudioProjects\ClBooking-master\Bookingtest.iml does not exist
Would you like to remove module 'Bookingtest' from the project?
I don't understand why a file doesn't exist when I cloned the project right from the github.
Another Error that come up with the Gradle Sync is and External Native Build Issue.

I've tired to search for answers on this subject and have come across some answers that are similar to my question except they are not solutions for my specific question.
I'm stuck at a wall and don't know what to do to resolve this Error. All I want to do is clone a repo from github and work on the project in Android studio. All of my SDKs are installed.
This may be caused by the space in the folder C:/Users/David Ferrara/AppData/Local/
If so, it is likely a bug in Android Studio, CMake, or ninja
