android - Does using interface in android app hurts app performance

Question

In one presentation deck of Reto Meier, I read his suggestion to prefer virtual methods over interface but there were no more explanation. Apart from the runtime overhead is there anything else which specifically hurts app performance in android ? Because to make code more flexible and readable I heavily use interface in my android project.
