Eclipse中编写jni c文件中报错Type could not be resolved

如下

Type 'JNICALL' could not be resolved
Type 'jstring' could not be resolved
Type 'jclass' could not be resolved
Method 'NewStringUTF' could not be resolved
Symbol 'NULL' could not be resolved

出现的提示信息如下：

Multiple markers at this line
  - Syntax error
  - Type 'JNIEnv' could not be resolved
  - Type 'JNICALL' could not be resolved

是由于没有将jni.h导入的缘故，而这个文件在ndk的目录下面。所以，参照以下步骤：
Project Properties -> C/C++ General -> Path and Symbols
选择include标签，Add -> $Android_NDK_HOME/platforms/android-14/arch-arm/usr/include
且选中All languages. 最后Apply -> OK 这样错误就解决了。

NdkDemo代码已上传至Github
