Android :: App Widgets And Remote Views

I've just spent the last few hours nosing around to see what's new in this 1.5 pre-release. I decided to implement an app widget to try out the new package. From the provider end it's very straightforward, but I'm not certain about the performance implications.Specifically, I decided to implement a clock (see http://www.tomgibara.com/android/babilo for a screenshot). In my implementation I render the clock image into a bitmap and have a very simple remote view that consists of a single image view to display it. This means that the bitmap must be marshalled on every update and the process must be in memory too of course. That's a lot of memory for a clock. Is there a better approach? Or is a non-digital clock ill suited as a widget?Also is there a way for the widget provider to know (receive a hint for) the size at which the widget will be rendered? This is useful in this instance since one doesn't want to make the bitmap any larger than necessary.
