Stopping it with a task manager/killer may only cause the service to restart. Sometimes it won't, but sometimes it will and the task killer will try again, creating a resource draining loop because the task killer itself is also draining things as it keeps restarting itself and the app/widget you're concerned with.
I just let the OS handle things, unless I notice slow down, then I'll go in and find out what's up, which is most often too many things running at once, in which case I'll go ahead and reboot the device.
The whole idea is to let you play music while your're multi-tasking on your phone. That said I do agree there should be a "quit" option like on Pandora or TuneIn Radio. Now the Music Player does mute itself while a call is in progress. My advice .... just use the drop down menu to control the player (note there is a CD DISC icon on top of the lock screen) or perhaps find a new music player in the market. A widget would be a nice feature. I like the way Pandora is set up.
That's just the thing. It isn't running in the background. If it's running it would be using CPU cycles. When you hit pause and hit home, the player stops but stays in RAM. If it's not using CPU cycles, it isn't using battery.
Android manages the RAM and will (most of the time) kill processes that are idle to free up RAM if more is required. Some people do this themselves using task killers.
It doesn't hurt anything to have it sitting in RAM, other than you won't see as much free.
No, it's not "running" per se, as it's using no CPU cycles (Well, minimal, since it needs the CPU to poll it, etc).
It's sitting there (A portion) in RAM, waiting to be called again, ready where you left it. If you don't use it for a while, and RAM gets gobbled up by more recent processes, it will push it out of memory for you
That's the thing with these phones. You can either let them do what they're supposed to do, or you can do the work for them. Seems like if you keep closing it, it'll actually use more battery than just letting it sit idle.
they intefere with how android manages memory...despite what verizon will tell you in the store.
these phones are linux-based...no mini windows computers.
now you can use programs like minifree manager or autokiller (root for both) that will play nicely with androids memory management *IF* you know what your doing to mess with the free app settings and such
