IntelliJ IDEA, import OpenCV Library

What do you mean by static linking? The library contains of 2 parts, jars and native code. You just add it to the module dependencies: http://www.jetbrains.com/idea/webhelp/configuring-module-dependencies-and-libraries.html.

Ensure the native libraries are in PATH, added into dependencies or their path is specified via -Djava.library.path=... when running.

Did everything as you wrote, does not work.

What's my mistake?

Thanks.

The warning message clearly states what's the problem. You can't have non-Gradle Java module and Android-Gradle module in the same project.

If your project is Gradle based, dependency should be added via Gradle (via jar dependency, not via Java module dependency).

>> What do you mean by static linking?

Without the support of OpenCV Manager (App).

Importing from Eclipse (Default OpenCV Project).

Previously, I used this material: http://answers.opencv.org/question/14546/how-to-work-with-opencv4android-in-android-studio/ 

https://github.com/ctodobom/OpenCV-3.1.0-Android might be easier.

Thank you! How to be with static linking?

No idea, ask on OpenCV forums. As far as I can see this approach doesn't require the manager app.
