Is there a library for dynamic hints?

Question

Android

Hey!
In different applications I see such hints: let's say they added some kind of thread button to the activity, and when you first open this activity, it is highlighted with some kind of circle thread, the rest of the screen is filled with some kind of thread with a translucent background, and there are hints on it, such as this button for that -something and close button;
You press the button - this background folds so cool, well, you continue to use the activity.
Can you tell me if there is a library for this thread? It is unlikely that every application writes its own implementation.
