The end goal is to build opencv with contrib for Android, but i cant seem to get the build_sdk.py script to even work without the --extra_pack flag
I've downloaded build Tools 25.0.3, sdk tools 25.2.5,, ndk 16b and the latest opencv and contrib repos.
Commands:
export ANDROID_SDK=/home/wmmc88/Android/Sdk/
export ANDROID_NDK=/home/wmmc88/Android/android-ndk-r16b/
python3 ../android/build_sdk.py test/ ../../../opencv --no_ccache --config ../android/ndk-16.config.py
Output:
