The droid-fu open source library has a handful of methods to help you apply a karate chop to slice your development time drastically. The library is composed of utility classes that do all the mundane heavy lifting for you, such as handling asynchronous background requests, retrieving images from the web, and, most amazingly, enhancing the application life cycle.

Also check out ignition, a replacement for droid-fu by the same authors but now in the alpha stage.
