Android Interface As iOS delegation

Delegate is a pattern to make communication between two objects.In the same way we use interface in Android to create communication between two objects

In iOS Delegation is a common way of organising certain aspects of the Objective-C code for an iOS app. "A delegate is an object that acts on behalf of, or in coordination with, another object when that object encounters an event in a program."

Most useful scenario of using Interface/Delegation is when we call web-service and we need to push result to controller class. 

• We can callback method through Interface in Android as we create in objective c with delegate.

So hear is an example of Android code to call web-service and give response to its controller class.
