Undefined Reference in JNI

Question

I am declaring a JObject NewObjectV.

jobject NewObjectV (JNIEnv *env, jclass cls, jmethodID methodId, WIMAX_API_DEVICE_ID_P pDeviceId);

But am getting the following error

undefined reference to ' android :: NewObjectV(_JNIEnv *, _jclass *, _jmethodID *, _WIMAX_API_DEVICE_ID_P *).

What should be the code to remove this error?

My complete code is

void fun_IndDeviceStatusUpdate(WIMAX_API_DEVICE_ID_P pDeviceId, WIMAX_API_DEVICE_STATUS deviceStatus, WIMAX_API_STATUS_REASON statusReason, WIMAX_API_CONNECTION_PROGRESS_INFO connectionProgressInfo) {

JNIEnv *env = NULL; 
int nResult = -1; 

// LOGD(" AttachCurrentThread() ->D1");

nResult = g_jVM->AttachCurrentThread(&env, NULL);

// LOGD(" AttachCurrentThread() ->D2-%d",nResult);

if ((nResult != 0) || (env == NULL))
{ 
    LOGD(" AttachCurrentThread() failed");
} 
else
{

// LOGD(" AttachCurrentThread() ->D3");

    if(deviceStatusChangeCB == NULL)
        {

            LOGD(" deviceStatusChangeCB is NULL ");

    }
    else
        {
            LOGD(" deviceStatusChangeCB is not  NULL ");

    }

    jclass cls = env->GetObjectClass(deviceStatusChangeCB);

// LOGD(" AttachCurrentThread() ->D4"); jmethodID methodId = env->GetMethodID(cls, "callback", "(Landroid/net/wimax/structs/DeviceId;III)V"); jobject NewObjectV (JNIEnv *env, jclass cls, jmethodID methodId, WIMAX_API_DEVICE_ID_P pDeviceId);

// LOGD(" AttachCurrentThread() failed->D5"); if (methodId) { LOGD(" STARTING CALL VOI D ");

        env->CallVoidMethod(deviceStatusChangeCB, methodId, NewObjectV, deviceStatus, statusReason, connectionProgressInfo);
    }

    if (g_jVM->DetachCurrentThread() != JNI_OK) {
        LOGE("%s: DetachCurrentThread() failed", __FUNCTION__);
    }
}

// LOGD("JNI->CALLBACK->D3");

    }
