In a native function with a jbyteArray argument, I want to pass data back into the calling app using SetByteArrayRegion.
I would like to resize the array to exactly fit the data, is that possible?

You can’t. Arrays are fixed size in java.
Possible solution would be to use a different data structure (e.g. ArrayList) or you could create a jbyteArray of the correct size and let the native function return this.
