Since the new opencv 2.4.4 is now released in desktop Java, is it now possible to host opencv codes in Google App Engine? If possible can anybody please provide some pointer on some introductory tutorial on this?

Thanks in advance.

I am using windows and trying to build OpenCV Tutorial 3 - Add Native OpenCV in OpenCV4Android 2.4.3. I have followed all the instructions in the following two tutorials http://docs.opencv.org/doc/tutorials/introduction/android_binary_package/android_dev_intro.html#cdt-builder http://docs.opencv.org/doc/tutorials/introduction/android_binary_package/dev_with_OCV_on_Android.html#native-c

I am trying to build the tutorial 3 in Eclipse and getting the following in console,

17:45:42 * Auto Build of configuration Default for project OpenCV Tutorial 3 - Add Native OpenCV * "C:\android-ndk-r8b\ndk-build.cmd" "Compile++ thumb : native_sample <= jni_part.cpp

In file included from jni/jni_part.cpp:1:0: C:/android-ndk-r8b/platforms/android-14/arch-arm/usr/include/jni.h:592:13: note: the mangling of 'va_list' has changed in GCC 4.4 SharedLibrary : libnative_sample.so

Install : libnative_sample.so => libs/armeabi-v7a/libnative_sample.so

17:45:44 Build Finished (took 2s.247ms)

The libnative_sample.so file has been correctly produced. Still, I am getting error that "There is error in the project". Then I've gone to jni_part.cpp and it is showing that it is not getting the header "vector". and it is not understanding the namespace "std". It is also not being able to find FastFeatureDetector. How can I compile it and run it?

Thank you very much. The information was very helpful.

I am much impressed to watch the performance boost achieved by enabling the tegra optimization (https://play.google.com/store/apps/details?id=org.opencv.imgdemo). But I was wondering how can I do that in my code. I could not find any helpful documentation on how to utilize tegra power in the opencv website. Can anyone please help me on this?
