http://code.opencv.org/issues/4185
Hello,
I finally get a ride of Android build from sources.
This is built only for arm devices.
you can found the libnative_camera_r5.0.0.so here : https://svn.scolring.org/trunk/dependencies/OpenCV/SDK/android/armeabi-v7a/sdk/native/libs/armeabi-v7a/libnative_camera_r5.0.0.so
the modified camera wrapper :
