Problems with android devices having Android 3.0 or lower version but works well with Android 4.0 and higher version about javacv HOT 5 CLOSED

The Samsung Galaxy Y S5360 seems to come with an ARMv6 processor, which isn't 
compatible with ARMv7. You'll need to recompile the binaries for ARMv6 (or 
ARMv5) as instructed in the README.txt file of the "cppjars" package.

Please post your questions on the mailing next time if possible, thank you!

Thanks for your quick and valid reply.
I read the README.txt file of the "cppjars" package but i could not recompile 
the binaries for ARMv6. I also reffered the thread 
https://code.google.com/p/javacv/issues/detail?id=60 (issue no. 60)
and downloaded the "OpenCV-2.2.0-android-armv5.zip" file as you provided the 
link to download precompiled OpenCV 2.2 for ARMv5. I replaced all the .so files 
of opencv-2.4.5-android-arm with the new one, you provided for ARMv5.

But when i execute the facepreview sample with these changes at my Samsung 
Galaxy Y(with armv6), it crashes and i got the following logs this time.

Can you provide me precompiled binaries for armv6.

There's two problems here:
1. Android does not support ARMv6, only ARMv5 or ARMv7.
2. Although ARMv5 is compatible with both ARMv6 and ARMv7, since it doesn't 
have an FPU, the performance is something like 100 times worse.

Is it OK for your application to be 100 times slower?

Thanks for your quick reply 
i agree with your point but still i want to execute it at my Samsung galaxy Y 
just for curiousity, want to see it working at this device.
So, i need appropriate precompiled binaries for this device.

Hi Samuel.
As i am using javac. Great work done by you. I am facing one problem. i want to 
rotate an IplImage at 90 degree angle. cvFlip(IplImage, IplImage,int param) is 
also there to flip the image but it is not rotating my IplImage at 90 degree 
angle. Please help me out.
Thanks
