Hi,

I would like to include the opencv-3 android SDK directly into my NDK project, to avoid absolute paths in Android.mk. So what I did was to move the "sdk"-folder to the project's directory, and instead of including "\native\jni\OpenCV.mk" using an absolute path, I used a relative one.

However, ndk-build then complains with:

C:\Users\User\AndroidStudioProjects\OpenCV3Native>C:\ndk\ndk-build V=1 Android NDK: ERROR:jni/Android.mk:opencv_shape: LOCAL_SRC_FILES points to a missing file Android NDK: Check that /../opencv3-sdk//native//jni//../libs/armeabi-v7a/libopencv_shape.a exists or that its path is correct C:/ndk/build/core/prebuilt-library.mk:45: * Android NDK: Aborting . Stop.*

I am quite new to android native development, so it is unclear to me what is going wrong here. Is there any way to include opencv-3 using a project relative path?

Thank you in advance, Clemens

There do not seem to be special NEON-optimized binaries available for the native OpenCV SDK (compared to the OpenCV4Android Java Wrapper / native library manager). Is NEON detected at runtime, or is it required to build OpenCV myself, setting ANDROID_ABI to "armeabi-v7a with NEON"?
