Error: type "JNIENV" cannot be resolved

Question

I am new to Android NDK launching the first hello JNI example. I added the jni folder and added the c file, in which I get an error that some of them are not allowed.

I also convert the project to C / C ++ and add NDK to eclipse as shown below

But there is still a red line of error in the cpp file, which indicates that some of them cannot be resolved.

Guys help me!
