Hello again! I imported the OpenCV samples in Eclipse and encountered errors like "C:/.../android-ndk-r4-crystax/ndk-build.cmd" is not found in PATH.

How can I resolve these errors?

I downloaded android-ndk-r4-windows-crystax-4.zip from this website http://www.crystax.net/android/ndk-r4.php but I can't find ndk-build.cmd . Screenshot of my directory. image description

You're trying to use an outdated NDK, please download the official version 8b from Google and the problem should disappear.

@Andrey Pavlenko. I downloaded the new Android ndk called android-ndk-r8b-windows. I extracted the file to C:\android-ndk-r8b and added it to the PATH (System Properties->Advanced System Settings->Environment Variables) . This gives me the error "C:/android-ndk-r8b/ndk-build.cmd" is not found in PATH". I can see the ndk-build.cmd in the directory but Eclipse didn't detect it.

I suggest you don't use Cygwin.

Then what will I use? How did you manage to install your opencv in eclipse? Please.

Use the tools mentioned in the Tutorial (http://docs.opencv.org/trunk/doc/tutorials/introduction/android_binary_package/android_dev_intro.html#manual-environment-setup-for-android-development): Oracle/Sun Java (JDK 6), Eclipse+ADT, Android SDK & NDK.

I installed the tools and followed the instructions. But there's a problem in Building application native part from Eclipse (CDT Builder). I've encountered errors on ndk-build.cmd. It's in my directory but Eclipse doesn't recognize it. I really need to proceed. How did you installed your opencv Sir?
