Hello, I know that using task killers are not necessary, but I'm wondering about a particular scenario. I will open Facebook for Android on my phone, just to check out news feeds, etc. However, when I leave, I'd like to make sure FB closes down. Instead, it seems to stay running, which indicates to people that I'm still on (and I get chat messages, etc., which I end up not seeing, because by then, the phone is already in my pocket). What's the best way to ensure that when I *exit* Facebook, I actually exit it -- I only hop on my phone to check things out quickly; I'm not looking to be a hardcore user (so, for chatting, for example, I do that from a desktop/laptop). Do I have to actually go into "manage applications" and force stop it there? Thanks!
