Memory allocation in Android widget

I have developed a widget in Android and it uses too much RAM (over 30 MB). What can it开发者_开发百科 be that takes up so much memory? The widget is a clock and weather widget that uses different skins (saved as drawables).

Thanks

It's hard to say could be a lot of thing. But lucky for you Android DDMS has a Allocation Tracker, that might help you solve your problem.
