我工作的一个简单的OpenCV code索贝尔接受手术后才能显示图像。我已经包括了所有必要的路径的项目属性，包括 OpenCV4Android 文件夹。我决定除了一个所有的错误：

I am working on a simple OpenCV code to display an image after undergoing sobel operation. I have included all the necessary paths to the Project Properties for including the OpenCV4Android folder. I resolved all the errors except one:

错误：方法NewStringUTF（）无法解析

我列入＆LT; jni.h＆GT; 我也包含在项目的路径AndroidNDK文件夹。我的Eclipse是高度非predictable。此前，它工作得很好，当我开发在Android其它应用。 Eclipse是依赖于机器的？我能做些什么来解决这个问题？

I included <jni.h> I have also included AndroidNDK folder in the project paths. My Eclipse is highly unpredictable. Earlier, it worked fine when i developed other application on Android. Is eclipse machine dependent? What can i do to fix this error?

推荐答案

有机会，你在 CPP使用 C 语法文件

Chances are that you are using C syntax in CPP file

我有同样的错误

只需切换到正确的语法和问题都将迎刃而解 C语法

Just switch to the right syntax and Problem will be solved C syntax

return (*env)->NewStringUTF(env, "Hello from JNI !");

C ++语法

return (env)->NewStringUTF("Hello from JNI !");

切换从C到C之后++语法我的问题得到有效解决。

After switching from C to C++ syntax my problem got solved.
