Android Activity Lifecycle Callbacks: How to unset / clear them?

I read in the Titanium 3.4.0 changelog that activitiy lifecycle events are deprecated and callbacks should be used instead see changelog.

I was wondering if it is possible to remove a callback? I used to do the following:

activity.addEventListener('pause', stopRefresh);
// ... then at some point
activity.removeEventListener('pause', stopRefresh);

activity.onPause(stopRefresh);
