Yes, some straightforward code missing.

But even methods…
Look this:
@Override
 public void dismiss(OnDismissedListener listener) {
 AnimationUtils.registerCircularRevealExitAnimation(getContext(), getView(), (RevealAnimationSetting) getArguments().getParcelable(ARG_REVEAL_SETTINGS), getColor(R.color.white), getColor(R.color.prezi_blue), listener);
 }”
-> the method and the listener

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
