1. 反射的基石:Class java程序中的各个java类属于同一类事务,描述这类事务的java类名就是Class。 Class常用方法: isPrimitive()//是否基本类型字节码文件 isArray()//是否数组类型的Class字节码文件 //类的基本组成:Field、Method、Contructor、package Method getMethod(); 1. 2. 3. 4. 5. 6. 7. 8. 9. ...
2、运行javah 命令:javah -classpath E:\work\java\workspace\JavaJni com.sundy.jnidemo ChangeMethodFromJni 本文生成的C/C++头文件名为: com_sundy_jnidemo_ChangeMethodFromJni.h 在C/C++中实现本地方法 生成C/C++头文件之后,你就需要写头文件对应的本地方法。注意:所有的本地方法的第一个参数都是指向JN...
