I can't speak to Android, but JNI passes values just like Java does, primitive types are passed by value and all objects (including arrays) are passed by reference. The wiki article on JNI is pretty good.

It depends on the type. Primitive types are passed by value and reference types by... reference. See http://java.sun.com/docs/books/jni/html/types.html
