Hello,

I want to use my OpenCL lib to process image on my moto Z. I get the so file of the library and now I would like to use it in my project in Android Studio.

I am not able to find a example of OpenCL process in Android Studio in c++.

Where could I get a sample example?

Edit:  I looked at the adreno SDK for linux, I notice that there are no OpenCL headers folder and no example contrary to the sdk on Mac.

Why that difference?

I try to build a project from that page:

http://arrayfire.com/getting-started-with-opencl-on-android/

The compilation works with nkd10e but when I run on my moto Z  I get that error:

I just try to use that page to link OpenCL:

http://arrayfire.com/getting-started-with-opencl-on-android/

But as soon as I link the libOpenCL.so on my project I get that:
