JNI错误(应用程序错误):本地引用表溢出(最大= 512)

我正在尝试运行LibSVMAndroidClassification Android项目与我自己的数据集。 它与已经提供的数据集一起工作得很好,当我用我的csv和100行(这是小于原始大小的1%)时,它也工作正常。 但是当我尝试去为例如1000行“训练CSV”,然后我看到这个错误。 我甚至试图在Manifest.xml中设置android:largeHeap =“true”,但没有任何改进。

这是我的logcat转储。

我已经search了很多,但我仍然无法理解背后的背景和原因。 很多人在不同的情况下都面临同样的错误。 什么可以成为解决scheme的合适指针?

提前致谢 !

您最好使用DeleteLocalRef来删除以后不再使用的本地引用。 例如

 for (int i = 0; i < 512; i++) { jobject obj = env->GetObjectArrayElement(array, i); //your code here env->DeleteLocalRef(obj); }
