The new ShowcaseView (v5.0)

This library has become more popular than I ever intended - but at the same time more unwieldy.This version is intended to be more stable,more friendly and better tested.

There are features missing compared to v4. If you'd like to keep using them, then use the legacy branch in this repository. Please see the bottom of this page for more information.

ShowcaseView library

The ShowcaseView library is designed to highlight and showcase specific parts of apps to the user with a distinctive and attractive overlay. This library is great for pointing out points of interest for users, gestures, or obscure but useful items.

The library is based on the "Cling" view found in the Launcher on Ice-Cream Sandwich and Jelly Bean, but extended to be easier to use.
