org.opencv.imgproc.Imgproc.Canny_3 Not not working in OpenCv 3.3.0 for Android

[gurankas]

System information (version)

• OpenCV => 3.3.0 for android
• Operating System / Platform => Windows 7 64 Bit
• Compiler => Android Studio gradle

Detailed description

I have linked the OpenCV library before calling the onCreate method. Loading of OpenCV library is successful. I am also able to use Mat, imgproc.cvtcolor but when I try to use imgproc.Canny, I get a UnsatisfiedLinkError in void org.opencv.imgproc.Imgproc.Canny_3

Steps to reproduce

Link the OpenCV library for Android, Click a photo and apply GuassianBlur, EdgeDetection, contouring and then Canny. That's how I set up my project

There is a dump of loaded OpenCV version above this line.

does this help?

[alalek]

No, version line is still cut (~20 lines above).
We need something like these lines and below:

i was using opencv 3.3.1 as part of my app, but opencv manager 3.0.0 downloaded from the play store. i had to uninstall the play store version and manually install opencv manager 3.3.1 using adb to make this error go away.

[ojgarciab]

I had the same issue resolved installing apk from downloaded sdk. Please, update play store manager! Thanks.

[igor036]

I just installed opencv apk what is on folder the sdk and canny started to work
