Java 释放JNI阵列 我在C++中实现回调函数，但是我面临一些漏洞问题。

数组创建的实现：

jshortArray convertShortArrayToJNI(JNIEnv* env, short* arr, size_t count) {
  jshortArray retval = env->NewShortArray(count);
  env->SetShortArrayRegion(retval,0,count,arr);
  return retval;
}

下面是回调调用：

short* audio_frame;
int size;
jobject* callbackObject;
jshortArray array = convertShortArrayToJNI(jenv, audio_frame, size);
LOGI("array %d", array);
jenv->CallVoidMethod(*callbackObject, callbackMI, array);
LOGI("callback called!");
jenv->ReleaseShortArrayElements(array, audio_frame, 0);

经过几次呼叫后，显示以下错误：

怎么了？

答案是：

调用

jenv->DeleteLocalRef（数组）解决我的问题

 对此不完全确定，但尝试删除对ReleaseShortArrayElements的调用。当您调用newshortaray时，该数组现在被放置在垃圾收集内存中。SetShortaryRegion只是将内存从缓冲区复制到GC堆中：释放您（而不是JNI）分配的内存必然会导致问题。将ReleaseShortArrayElements用于GetShortArrayElements。对此不完全确定，但请尝试删除对ReleaseShortArrayElements的调用。当您调用newshortaray时，该数组现在被放置在垃圾收集内存中。SetShortaryRegion只是将内存从缓冲区复制到GC堆中：释放您（而不是JNI）分配的内存必然会导致问题。使用ReleaseShortArrayElements获取ShortArrayElements。
