If you're pulling down a large-ish collection of data from the database, and you want to convert that all into a JavaBean type collection, you may want to offload that onto another thread as the size of data its use of reflection may cause too much work for the main thread. The only way to know about this for sure is to benchmark it yourself. Generally speaking, you get 16ms to do things on the main thread before you start dropping from the optimal rendering speed of 60 frames per second.

I recently tweeted a diff on a project of mine where I refactored a pattern for sending database listener to an Executor for background processing. However, your app may not call for this kind of complexity. It was good for my app, however. https://twitter.com/CodingDoug/status/773277680867258368
