What types of leaks get reported in logcat and what other ways or tools do we have for finding leaks?

I'm beginning Android development and I am concerned about leaks.

I think thread leaks can get reported in logcat if memory serves. But what other types of leaks get reported by logcat? I have gotten feedback about potential leaks that concerns me and I take it very seriously.

What other 开发者_C百科ways do I have for detecting leaks? For example can I instrument my code so that an otherwise unnoticeable leak will show up in logcat?

Thanks for any reply. Happy coding.

Great talk at IO this year on the subject http://www.google.com/events/io/2011/sessions/memory-management-for-android-apps.html

There's the Allocation Tracker tool in DDMS, that goes down to a very detailed level. Here's some info from Romain Guy (one of the folks on the Android dev team at Google):

Extremely valuable tool.
