Issue #2035 Calling cv::namedWindow crashes on Android fixed.
Window-related functions is guarded from calls from application code.
Old implementations with "no-gui" exception are stell compiled and linked to OpenCV library for binary compatibility.

You know, cv::namedWindow is not supposed to work on Android anyway. It is not so easy to create a window on Android, because all applications have a single window and are fullscreen. So, we didn't decide if we would allow such calls (and other GUI related calls from highgui).

But crash is unexpected behavior in any case. Could you please provide more details about your appication? Did you modify some of OpenCV4Android samples? Or your application is command line? If you could attach a small sample that shows the problem, it would be very helpful for us...
