Is it possible to generate binding for already compiled shared library for Android?

[mSerdcevas]

Hello,
I couldn't find example how to generate binding for already compiled library. I tried using gradle-javacpp-android as example but I couldn't figure out how can I link my shared library.
I have 4 libraries for 4 architectures:

lib
|-arm64-v8a
    |-libtest_library.so
|-armeabi-v7a
    |-libtest_library.so
|-x86
    |-libtest_library.so
|-x86_64
    |-libtest_library.so

test.h

#ifndef UNTITLED1_TEST_H
#define UNTITLED1_TEST_H

class Test {
    int m_val;
public:
    Test();

    int get_val();
};

#endif //UNTITLED1_TEST_H

Sure, what is the issue exactly?

This is my forked example I added libs to src/main/jniLibs added my test.h to src/main/cpp and edited NativeLibraryConfig

package com.example.myapplication;

import org.bytedeco.javacpp.*;
import org.bytedeco.javacpp.annotation.*;
import org.bytedeco.javacpp.tools.*;

@Properties(
    value = @Platform(include = {"NativeLibrary.h", "test.h"}),
    target = "com.example.myapplication.NativeLibrary"
)
public class NativeLibraryConfig implements InfoMapper {
    static {
        // Let Android take care of loading JNI libraries for us
        System.setProperty("org.bytedeco.javacpp.loadLibraries", "false");
    }

    public void map(InfoMap infoMap) {
    }
}

Where should I specify linkage to my test_library? Without linking to my library I get error:

app/src/main/cpp/jniNativeLibrary.cpp:760: error: undefined reference to 'Test::Test()'

You'll need to add that to the CMakeLists.txt file. This isn't related to JavaCPP, but with the CMake build system that comes with Android Studio.
