🔥 Android Studio 版本 🔥  

 🔥 创建包含JNI的类 JNIAccessMethod.java 🔥

package com.cmake.ndk1.jni;

import com.cmake.ndk1.model.Animal;

public class JNIAccessMethod {
    static {
        System.loadLibrary("access-method-lib");
    }

    public native void accessInstanceMethod(Animal animal);

    public native void accessStaticMethod(Animal animal);
}

 🔥 Java方法对应JNI中方法名称 🔥
