i've read several articles on the internet that state that android does not need a task killer. that it manages and closes tasks all on its own. however, last night i pulled up all my running applications. i was using over 300mb of ram. my phone had been idling for over an hour (screen off, no usage). and i still had applications running that i hadn't used in several hours such as gallery and tikl. shouldn't android have killed these apps by that point? and isn't 300mb of ram a lot at one time? edit: i also noticed that tikl uses quite a bit of ram. but every time i force it to stop, it comes back on its own without me even opening it.
