Android - OpenCV Template Matching

Question

So I'm attempting to follow this example: OpenCV Template Matching example in Android

I'm trying to use it with the updated OpenCV Examples which I have working. The difference I'm aware of in the updated examples is how the OpenCV libraries are added. The examples have you pull in a library project instead of a jar.

The error I'm getting is this.

Thanks in advance.

Answer 1

googling a little bit , you will found that you've called the template matching before loading the OpenCV library see the same error in openCV forum :

you can only call opencv functions after the BaseLoaderCallback finished(the opencv dlls were loaded). so, if you put that code into your onCreate function, you'll get that error.

you could find a complete BaseLoaderCallback documentation in openCV doc

Hope this could help you ^^
