Is there an Android Material Design onboarding/tutorial overlay/showcase library? [closed]

Question

I've seen this in Google Calendar. It looks cool:

I know about the old ShowCaseView and have seen RoboDemo but neither seem to be updated for Material Design.

Is there a library that means we don't have to roll/adapt our own?

Answer 1

There is now a library called MaterialShowcaseView.

Answer 2

I came across a reddit post with a similar question a while back.

https://www.reddit.com/r/androiddev/comments/38nu7x/how_can_i_make_this_onboarding_animation/

There was one library and one tutorial among the answers within.

I also came across the following while browsing android-arsenal.com (under the "Showcase Views" Tag.)
