GeekYouUp's Battery Widget includes a simple example of creating a graph/meter somewhat similar to the example posted. It's code and graphics are available at code.google.com/p/batterywidget/

Where will is the meter graphic to appear? On a main activity screen? In the taskbar? In an app widget? Live wallpaper?
