Android: implementing sliding cards in widget
I have a widget that periodically updates itself (hourly) to display top result of search query. I would like to extend it so it captures several top results and then loops through these. The best example would be `Genie News and Weather` widget for which I was unable to find a source code.

QUESTIONS:

 1. What would be a good way to implement the animation? I'm thinking `ViewAnimator` + timer, but is there maybe a better way, say `FrameLayout` + alerts? I'm already using `AlertManager` to periodically pull search results for the widget
 2. How bad such arraignment would affect phone's battery life?
