void onSuccess(String result) {
//Do what you need to do

if(callback != null) { callback.onSuccess(..); } //notify caller
via callback
}

//Do what you need to do
....
if(callback != null) { callback.onFailure(..); } //notify caller

SuccessType and FailureType can by anything including Void if you don't
care about information and just want to be notified.
