JNI修改Native方法數組參數中數組裏面的元素值

JNIEXPORT jintArray JNICALL Java_com_example_feisou_a02_1helloworld_JNI_arrElementsIncrease
        (JNIEnv *env, jobject thiz, jintArray jarray){
    jsize  length = (*env)->GetArrayLength(env,jarray);

        *(arrayPointer+i) += 10;
    }
    (*env)->SetIntArrayRegion(env, jarray, 0,length,arrayPointer);
    return jarray;

}
