jni.h 文件的相关文章

jni.h头文件详解(二)

一:struct JNINativeInterface_{} 结构体的作用:它有点像我们char字符驱动的 file_ops结构体,它定义各种函数对在(jni.h头文件详解一)中定义的各种数据的操作函数集体． 二:它包含那些针对Java中类和对象的相关操作呢如下图． 三:下面我们讲详细介绍14个部分方法的用法和解析 3.1.版本信息操作函数. 一.GetVersion jint (JNICALL *GetVersion)(JNIEnv *env) --模块信息:该模块主要针对的JNI接口的版本信

jni.h头文件学习笔记

Now :2015年 6月 8日 星期一 22时17分05秒 CST Note: 这篇笔记是我半年前写的,当时因为某些原因经常需要写jni方面的代码,所以就深入学习了下jni方面的知识,现在再来看之前写的东西,一句话概括就是深度不够,废话太多.因为这是一个不全的笔记(还有一部分想写的内容未能写上),所以当初想分享给其他同事的也不好意思分享. #-------------Add Now-------------# jni是java native interface的简写,是java和c/c++通信

fatal error C1083: 无法打开包括文件“jni.h”

在cocos2d-x vs2010编写HelloWorld中,想使用JniHelp对C++和java进行调试,出现错误: ..\cocos2dx\plateform\android\jni\jnihelp.h(27):fatal error c1083:无法打开包括文件“jni.h” 我使用的java路径在:C:\Program Files (x86)\Java\jdk1.6.0 vs2010工作目录在:C:\Program Files (x86)\Microsoft Visual Studio

android NDK开发编译C++文件出现Type &#39;jint&#39; could not be resolved和Unresolved inclusion: &lt;jni.h&gt;的解决办法

今天在编译android NDK工程的时候,在jni文件夹下的cpp文件中报了一大堆错误,诸如:Unresolved inclusion: <jni.h>.Type 'jint' could not be resolved.Type 'jintArray' could not be resolved等,根据经验,这样的错误肯定是没有包含相应的头文件导致的. 解决方案: 选中工程,右键->Properties,点击C/C++ General展开,点击Path and Symbols,在右边

简单地迁移你的android jni代码逻辑到iOS - 编写iOS下jni.h的替代 - ocni.h

1. jni的代码逻辑中与上层平台语言交互了. 2. 使用非Xcode的ide开发工具,希望使用纯净的c/c++代码,不掺杂其它平台相关的语言语法. 3. 只想简单地替换jni代码对上层平台语言的功能调用. 对了,本文就是这样一个出发点. 先说一下jni.h头文件是为jni代码(c/c++)去使用java平台层的对象(功能)提供的c或c++接口集.如果在iOS平台OC层的生态环境下比较容易就可以实现同样功能的java对象,你的jni代码就不用去改变逻辑,只要将向java平台层访问的地方改成对同等

创建JNI头文件

1. 创建JNI头文件 在工程目录下输入: javah -classpath bin/classes -d jni com.example.rgbir.rgbirJNI  遇到的问题 error: cannot access com.example.rgbir.rgbirJNI class file for com.example.rgbir.rgbirJNI not found javadoc: error - Class com.example.rgbir.rgbirJNI not foun

jni.h No such file or directory

如果有如下错误: fatal error C1083: Cannot open include file: 'jni.h': No such file or directory 将以下文件: \jdk\include\jni.h \jdk\include\win32\jawt_md.h \jdk\include\win32\jni_md.h 复制到VS的安装目录下的\VC\include目录中
