Hello, I'm new to OpenCV and more generally to "computer vision" and android.hardware.Camera. I try to run the examples (tutorial-0-androidcamera et tutorial-1-addopencv) and nothing works.
For the first, the LogCat say :
- 09-21 14:35:47.800: E/BufferQueue(15201): [unnamed-15201-0] setBufferCount: SurfaceTexture has been abandoned!

And for the second :

I saw that there were some known issues with the previous version, but were theoricaly corrected with the latest one. However, I tried to compare yesterday solutions with today's code, and i can't explain what's going wrong.
I used this package : http://sourceforge.net/projects/opencvlibrary/files/opencv-android/2.4.2/OpenCV-2.4.2-android-sdk.zip/download
sorry for my bad english
