Java – do I need to call releaseintarrayelements on an array created using newintarray?

I have a local method to do some work on bitmaps Inside the method, I obtain image data through a method call, which writes the data into the jintarray parameter created using newintarray:

jintArray pixels = env-> NewIntArray(width * height);

I don't need to return this array to the calling java code - it's only used for processing in this method Do I need to call releaseintarrayelements on pixels? If so, what do I pass the elems parameter because I don't need to copy it back to the Java array?

Void (jnical * releaseintarrayelements) (jnienv * Env, jintarray array, jint * elements, jint mode);

Solution

You don't need to do anything It is a local reference that will be cleared when your JNI method exits As Edward Thompson mentioned, releaseintarrayelements() is the opposite of getintarrayelements() It has no other functions
