how exactly do u close an app?

[anyways]

I though by going back to home an app will automaticly close, but I was wrong, it actually suck ur memory to death and I can't seem to find that sweet X that u see in windows window.

You don't. There's a few threads about this, search Linux is dif from Windows. I sure would like to be able to close down some apps, but i have gotten used to it.

Please read my post in this thread. Bottom line: Hit the home button to close an app.

You have nothing else to worry about.

Gibbage, I'm sorry, but that just doesn't make any sense to me. I've had programs that have been searching for information, I hit the home button, go to another app, hit the home button again, and go back to that original app, and its still loading. I just don't buy it that the home button kills applications.

That makes no sense at all. Linux is indeed different from Windows, but that does not explain why there's no close button on Android. Applications left running may continue to use resources, but they have to be able to give up these resources at a moment's notice. When the foreground application needs more resources, the OS can redistribute them.

In short, you need to keep on hitting the back button until it backs itself out to the home screen.

Long explanation:
1. If a program is doing something, then it will continue to run in the background.
2. If the program stops doing stuff and it is no longer in the foreground, Android keeps it in "hibernate" mode (in Windows terms). In other word, the system memory state of the program is dumped to storage memory.
3. When the program is loaded again, Android looks to see if there is an instance of that program hibernating. If so, it will load the hibernating instance; otherwise, a fresh new instance.
4. Android treats almost all applications as web pages, unless specifically told not to. What I mean is it keeps "browsing history" for each application so that when you hit "back," you would be returned to the previous state of the application, just as if you hit "back" in a browser.
5. Putting everything together, what this means is that if you simply hit the home button, you might not be erasing the history portion of the application. This over time will kill your system memory.

You can try this out by going into Google Talk, keep on starting and closing conversations with people on your list. After a while, try hitting the "back" button and see if Android brings you back to the list of the 4 chat clients. It won't. In fact, it will act as if you have not pressed anything. The reason is the previous state of Google Talk probably looks identical to the one you are navigating away from. Keep hitting the "back" button and you might see some interesting things, i.e. people who you know are offline would suddenly come online. You probably have to hit the button a dozen times before it finally exits you out. At this point, the memory dump for Google Talk is likely to be a lot smaller than if you hit the "home" button directly.

So you see, if you keep on using the "home" button, it won't take long before both your memory and your battery get depleted, not to mention at some point opening up a hibernating app would instantly cause your G1 to crash and reboot.

^^ good explanation ^^

I just use "Task killer" to close the applications I don't want to stay running, otherwise applications like twitdroid will keep looking for new twits and run in the background.
