Error base operand of '->' has non-pointer type 'JNIEnv {aka _JNIEnv}' when create NDK project

Question

I create my first NDK project, that show some text on screen. I use native method in class NativeLib in java and implement in a class in C. But I received an error base operand of '->' has non-pointer type 'JNIEnv {aka _JNIEnv}

 #include <jni.h>
 #include <string.h>
 #include <stdio.h>
 #include <android/log.h>

#define DEBUG_TAG "MY_NDK_DEMO"
JNIEXPORT jstring JNICALL Java_com_example_helloworld_NativeLib_helloWorld
  (JNIEnv * env, jobject obj) {
    return (*env)->NewStringUTF("Hello World JNI!");
}

Why is that different for C++? – Ciro Santilli OurBigBook.com Jun 22 '16 at 17:26

c++ is different from c so to make it work use env->NewStringUTF("Hy");
