Choice of implementation interaction of fragments?

Question

Android

guys got a question. I use fragments in my application. The fragment has a button to move to another fragment. I implemented it using the interface (Processing an event from a fragment in an Activity, the code comes out in order more than the second way), well, I was also able to implement it directly without using the Activity using the usual button processing, which creates a fragment and changes it with the current one. Which of the methods is considered more correct and flexible?

Answer 1

it all depends on your architecture, both methods have the right to life, as well as a number of other methods - whichever is more convenient and do it
more code not the mvp / mvvm metric even more code and nothing, use )
