NDK(4)"Unresolved inclusion jni.h”的解决方法

3种解决办法:

1.重新初始化eclipse对该project的native support

1. 在eclipse中关闭指定Project

2. 用其他编辑工具打开该project的.project文件，删除以下内容：

后面几行在<nature> 下

     ......
     <buildCommand>
         　　<name>org.eclipse.cdt.managedbuilder.core.genmakebuilder</name>
         　　<triggers>clean,full,incremental,</triggers>
         　　<arguments>
         　　</arguments>
     </buildCommand>
         ......
     <buildCommand>
     　　<name>org.eclipse.cdt.managedbuilder.core.ScannerConfigBuilder</name>
     　　<triggers>full,incremental,</triggers>
     　　<arguments>
         　　</arguments>
     </buildCommand>

         ......

     <nature>org.eclipse.cdt.core.cnature</nature>
     <nature>org.eclipse.cdt.core.ccnature</nature>
     <nature>org.eclipse.cdt.managedbuilder.core.managedBuildNature</nature>
     <nature>org.eclipse.cdt.managedbuilder.core.ScannerConfigNature</nature>

3. 删除.cproject文件

4. 在eclipse里打开原来的project， refresh，然后右键->properties->Android Tools -> Add Native Support

2.include path

项目右键  > Properties   >  C/C++ General  >  Paths and Symbols  > Add ndk目录下的头文件

　　如: 我用的是19,21出错.

　　/home/admin/Android/android-ndk-r10e/platforms/android-19/arch-arm/usr/include

3.重建项目

　　保存 .project 到其它目录,当按下面操作失败时,再把 .project 拷回来.

just pointed NDK location under Preferences > Android > NDK.I created new, clean Eclipse workspace.Deleted from my project with C++ code next files/folders:

.settings
.classpath
.cproject
.project

Eclipse > New > Other > Android > Android Project from Existing Code > then point folder with your project, let Eclipse detect it, check "Copy project into workspace" and click Ok/Next, whatever.Clean project.Right click on project > Android Tools > Add native supportRebuild, possibly restart workspace.
