One week ago, we featured a guide by XDA Senior Member marty331 posted in our App Development forums aimed at helping application developers create in-app usage tutorials using transparent demo overlays atop application activities. However, not everybody is a designer able to create aesthetically appealing overlays. Luckily, XDA Senior Member nikwen discovered the open source ShowcaseView library by Alex Curran, which makes it easy to generate Holo-themed demo overlays with ease.
In addition to describing the Apache 2-licensed library, nikwen also put together a quick guide that teaches developers how to showcase views, views in fragments, and parts of the action bar. He also describes how to add listeners to the library to trigger the event, as well as add animations such as a virtual finger that performs a gesture.
As we stated before, one of the keys to getting users comfortable and happy with your application is to show them how to use it. Head over to the guide thread to get started._________
