How to return a array which be created in native method?

Question

i wrote my native method like this:
jintarray array=env->Newintarray(10);
jint* p=env->GetIntArrayElements(array,0);
for(int i=0;i<10;i++){
p=i;
return array;
the result is that i got a array which has ten elements and all the elements are 0.
it seems the value of the array never be chenged.
how can i do? where is the mistake? how can i get the correct result?

Answer 1

Not quite clear what you are trying to do.
o You create a java in array, which will be initialized to zeroes.
o You then asked to access that array (as p), but you didn't pass a pointer to a boolean so it can tell you whether p points into the java array, or is a separate memory area.
o You assigned a bunch of int values to p - not p[0], p [1], ....?
o You returned to java the original array.
Here's some (untested) code that will likely work:
jBoolean isCopy;
jintarray array=env->Newintarray(10);
jint* p=env->GetIntArrayElements(array,&isCopy);
for(int i=0;i<10;i++){
p=i;
if (isCopy == JNI_TRUE)
env->ReleaseIntArrayElements(array, p, 0);
return array;
