OpenCV Java library not available

[Kleyson de Sousa Rios]

Hi,

I'm trying to come up with an Android project where I can use OpenCV in both Java and C++ on the same project.

I'm able to configure OpenCV Java using this tutorial https://github.com/kleysonr/opencv_android , where OpenCV C++ doesn't work.

And now - thanks for your great work on this - I can also have a project with OpenCV C++, but not working for Java.

Have you tried to have both Java and C++ working on the same project ? Do you have any idea about what can be done in your configuration to have OpenCV Java working as well ?

Best Regards.

Hi @kleysonr,
I found a solution to integrate the Opencv java stuff with android.
You can find a detailed explanation in my article here.

Initially I followed your instruction (because I forgot the steps). But the AndroidStudio compiler complains about the fact that wasn't able to find R.styleable.
After some search I found that is necessary to edit the Opencv build.gradle by setting the variable res.srcDirs = ['res'].
After this fix everything works fine. I hope you can fix it too.

Best Regards.

Hi @Luca96,

Actually I got it working at the same day late night :) I was planning update this issue with the steps this weekend.

My steps was the same that you did.

Regarding the issue below, the step 6 in my instructions is to avoid it.

After some search I found that is necessary to edit the Opencv build.gradle by setting the variable res.srcDirs = ['res'].
