Google Play services Task API: can a Task be cancelled

Question

When use )" rel="nofollow noreferrer">Tasks.call(Callable), can I cancel it, and remove all the listeners from the task?

Answer 1

If you need a way to remove all the listeners from any Task at any time, you will have to remember all the listeners you previously added, then remove them all manually.

If you're working with an Android app, and you add Activity-scoped listeners, they will be removed automatically when the host activity is stopped (goes through its onStop() lifecycle method). Note that you have to pass the activity as an argument to addOnCompleteListener().
