Sorry a task can't return a result, simply because it does not make sense -- for example the user can move out of the other task and back to yours without finishing it to return a result, or they can leave and go to another app that then launches the same task for a result and you now have that one activity instance trying to present the user with a UI to deliver a result to two different activities. The solution is probably to just not use singleTask or singleInstance. I think 90% of the time when people think they want to use these, they really don't.
