Steps to reproduce
- set env of path:
ANDROID_SDK,ANDROID_NDK - clone opencv source code and checkout branch 4.0.1
- build source code
mkdir build
cd build
python ../platforms/android/build_sdk.py
- Install the apk
o4a/opencv_android/face-detection/build/outputs/apk/debug/face-detection-armeabi-v7a-debug.apk
