使用JNI将数组数组从java传递到C. [英] passing array of arrays from java to C with JNI

问题描述

我有一个int数组，如int [] [] arrays = {array1，array2，array3，array4，array5};其中 array1 = 30,40,20,40 ， array2 = 40,20,30,30 我试图使用JNI将此数组发送到C.我找不到任何明确的解决方案。我试图把这个int作为一个inarray但没有成功。



有没有办法做到这一点？

I have a int array like int[][] arrays = { array1, array2, array3, array4, array5 };where array1=30,40,20,40 ,array2=40,20,30,30 and I am trying to send this array to C with using JNI. I could not find any clear solution for this. I have tried to take this int as a intarray but no success.

Is there a way to do this?

推荐答案

我发现这个很好的 JNI的Java编程教程示例为int数组。



非常重要的是要小心释放所有内存，否则jni会遇到麻烦而没有任何明显错误。

I found this fine Java Programming Tutorial for JNI with example for int array.

Very important is to release all memory carefully or the jni gets into trouble without any clear errors.
