Android Java代码与JNI交互基础数据类型转换(三)

Android Studio 版本  

基础类型数据的转换

定义传递基础数据类型到Native的JNI接口函数

package com.cmake.ndk1.jni;

public class JNIBasicType{
    static{
        System.loadLibrary("native-lib");
    }

    public native int callNativeInt(int num);
    public native byte callNativeByte(byte b);
    public native char callNativeChar(char ch);
    public native short callNativeShort(short sh);
    public native long callNativeLong(long l);
    public native float callNativeFloat(float f);
    public native double callNativeDouble(double d);
    public native boolean callNativeBool(boolean  b);
};

Native层创建callNativeInt 提供给Java调用
