Hi,
I know there are lots of posts regarding Android native camera access issues, but I think my case differ a little bit from other to post my own question... (hope i'm right :-) )
I'm trying to open a camera from a cpp code called from another library (libpd).
When I call :
new cv::VideoCapture(CV_CAP_ANDROID + 0);
The app crashes, logcat *:E tells :
E/SensorManager(21134): thread start

I'm surprised because the sample Native Activity works fine.
I'm using OpenCV4Android 2.4.6 r2 and targeting to Android 4.3 (also tried 4.1.2).
Could someone help me on this ?
Thanks ! a
