I want to draw my results (draw lines between point features) from the Optical Flow method via Android... To do this,I am trying to integrate the OpenCV libraries, but I have serious problems to do this... I tried to do it with different methods... Basically, I have two questions...

How is it possible draw lines in FastCV?  and How is it possible integrate Opencv-sdk-android with FastCV...?

I will appreciate any suggestion....


I have tried to add OpenCV libraries and FastCV in my Android project, doing this:
 1.- Adding my .a libraries in the library folder in my Android_ndk path.. (as:

for libs: $(ANDROID_NDK_ROOT)/platforms/android-19/arch-arm/usr/lib

for include: $(ANDROID_NDK_ROOT)/platforms/android-19/arch-arm/usr/include


But I get errors like:

error: undefined reference to 'vtable for tbb::task'

"error: undefined reference to 'gzgets'"

I understand which i will need to add more libraries, but i don't which and where they are...

2.- Trying to add  the Opencv sdk for android in my Android.sdk like this:

$(info $(LOCAL_SRC_FILES))
include $(OPENCV_PATH)



Finally, I discarded to use OpenCV and implemented a draw line function via Bresenham's algoritm
