In DataDroid Library, for executing request we use 
execute(request, listner)
Is there any method for executing request without using listner?
I need to send Information to server and for which the response is not related to    user.So, I will handle error and success case in Operation.
I dont want to override methods : 
onRequestFinished(),
onRequestConnectionError(),
onRequestDataError()
as there is no UI updation.
