android-opencv this is an example of an android library project that has some reusable code that exposes part of OpenCV to android. In particular this provides a native camera interface for loading live video frames from the android camera into native opencv functions(as cv::Mat's) to build make sure you have swig and the crystax ndk in your path cp sample.local.env.mk local.env.mk make that should work... more later on how to build actual project for android - see the code.google.com/p/android-opencv for details on this
