Possible to run process on Worker Thread instead of UI Thread?

[rezalaki]

Hi sir
thanks for your great library, it's much use full!

I am using 1.0.0v, and I logged the thread name in OnCompleteListener Interface. It is working on Main/UI Thread.
Have you implemented any solution to run the processes(create and restore backup) on Worker thread?
Or I myself must implement a solution for it (Rx or Coroutine)?

Thanks for helping or notifying if it is handled in newer versions
