jObjectArray尚未声明

Question

In my function, i am trying to get the size of a String array that has been passed to a C++ class through JNI, but i keep getting the error: "jobjectarray has not been declared". here is my C++:

int targetCount = 0;
    JNIEXPORT void JNICALL
    Java_com_example_processArray(JNIEnv *env, jobject obj, jobjectarray targetsArray){
        targetCount = env->GetArrayLenght(env, targetsArray);
    }

Not sure how to go about this because i thought it uses the Array already passed directly. Solutions greatly appreciated as always. Thanks

Use javah to create your jni signatures. jobjectarray is not correct, the correct syntax is jobjectArray
