Hi,
I'm trying to run this opencv4android example (android tutorial 4):
https://github.com/opencv/opencv/tree/master/samples/android/tutorial-4-opencl
The project compiles fine, but when i tryied to run on my Sony xperia Z3 Compact there is only a black screen.
Log shows me:

As we can see org.opencv.android.Camera2Renderer can't find the correct size and is returning size = 0x0. I don't know if it is a bug in Camera2Renderer or if I am missing something.
I`m using opencv 3.1.0.
