why are apps running when i dont open them? memory leak also..

could be a noob question
every once in a while i will go into my advance task killer and see a bunch of apps running that i didnt manually open. i just checked my phone to see sprint nav, mp3 store, droid locator, internet, ringdroid, etc.. it also takes my phone from 71m free to about 35-40m. ill kill the apps, and they will be open again without me touching the phone. am i stupid, or is there actually a problem?

Okay bc those stock apps are coded to run at startup, and open themselfs for ease-of-access, this is normal. If you want to stop that, add them to autokill, and use a startup manager (market) to remove them from the start up screen.
For the mem issues, try disabling the GPS lovation services, that eats up battery life AND mem, same with internet.

If you really want your phone to fly, don't use a task killer.

In theory this is true but in reality it couldn't be more misleading. Yes a task killer, especially one that is always running and using up resources itself is probably less than optimal in an Android environment, however they are sometimes necessary because things do not always work as they are supposed to. If you have root it is better to just use AutoKiller as it doesn't just kill programs but helps the OS by allowing you to set the limits for when the OS should start closing things. It also allows you to manually kill anything not working right.
Of course this is just my opinion, but I have tried it both ways on 3 different Android phones and my results were the same on all.

There's a section at the bottom that goes over this.
It's really more of an explanation that "Having free RAM will make my phone faster" will not make your phone faster.

task killers?

can anyone recommend a good task killer? ive tried atk on 2.2 but its very sluggish. i dl task panel x and it doesnt update frequently lol. i have autokiller memory but not sure if i am using it right lol. so if anyone is using a task killer, what r u using and r u getting good results? thanks in advance!

Do not use autokiller. I can't remember what problem it causes but it does indeed cause a problem on all galaxy phones. Or at laast my fascinate

You shouldn't need one from all I've read about it.
but I use system panel to kill an app here and there.

Don't bother using a task killer. I used Advance Task Killer for the last two weeks but it probably hampered things more than it helped. Your phone will NOT slow down to a crawl. Most custom ROMs use good minfree settings that'll keep your phone snappy.
Just uninstall your task killer, or if you want to use it, turn off autostart, turn off autokill, and only use it for pesky apps that won't die.

I was using ATK and could not verify any benefit. I read the following article and gained some more understanding. I have been running without a Task Killer since and I see no loss in performance or battery life. I could say I have less FCs and more reliability with syncing email.
Read This: http://lifehacker.com/5650894/android-task-killers-explained-what-they-do-and-why-you-shouldnt-use-them

i have been getting random shutdown these few days (started like 3 days ago), about 1 shutdown per day. i'm not sure if it' the stock task manager, dolphin browser beta 4.0, or widget locker 1.2.7 causing it. i already removed stock task manager and downgraded widget locker to 1.2.4 to see what happens.

Task killers aren't generally needed on android. If its battery life you want then for one try not to compulsively look at your phone preventing the cpu from idling and screen from turning off. Get juice defender. It turns off data unless it is needed. Most apps don't use resorces when the phone is asleep unless they are designed to, like file sharing programs or apps that sync data in the background but there are also bad apps. In froyo Use the built in task manager (long prsss on home) to see what's running. If you havent used something in a while and don't need the process active then close it.
If it is performance you want then no task manager will help. You need to alter the minfree setting which manages memory and how apps use it. I use the one click lag fix app to do that. Other apps I used caused problems. I set the minfree to moderate. Its more agressive than stock but doesn't kill processes you might want running. Anything more agressive than that kills allshare while im streaming movies but there is a performance increase when set to optimal or strict however it is slight.

Nook memory leaking...anyone else?

I am running auto nooter on my nc (lovin it) but i have noticed that the available memory is slowly leaking. On reboot, i usually have around 300 available and that number slowly but surely decreases until its so low that it reboots automatically.
I have advanced task killer installed and periodically kill all the tasks to make sure nothing is running in the background.
Any idea what might be causing this?

Advanced Task Killer is not helping you. Google has come right out and said Task Killers will do more harm than good on your Android device. Here is a good read:
http://android-developers.blogspot.com/2010/04/multitasking-android-way.html
The fact that you can see an application's process "running" does not mean the application is running or doing anything. It may simply be there because Android needed it at some point, and has decided that it would be best to keep it around in case it needs it again.
...
Once Android determines that it needs to remove a process, it does this brutally, simply force-killing it. The kernel can then immediately reclaim all resources needed by the process, without relying on that application being well written and responsive to a polite request to exit. Allowing the kernel to immediately reclaim application resources makes it a lot easier to avoid serious out of memory situations.

It will not reboot when it runs out of ram. My suspicion is you're seeing the 'random reboot' problem that happens on the stock B&N ROM. See here for a workaround: http://nookdevs.com/NookColor_Issues

I totally agree with this on 2.2 upwards... Unfortunately 2.1 is a little more lax about memory handling, and can sometimes get quite slow and jumpy and can benefit from a flush. I use System Panel and exclude all of my important tasks and widget, and if I see my NC getting jumpy or such, I'll kill all (which excludes those already excluded apps of course). But auto task killers are always a bad idea.

Thanks for the post, that was a great read and I am uninstalling my task killer now.

Regarding task killing, I recommend something like Watchdog to monitor apps as opposed to an auto-task killer. Watchdog has a really nice widget for monitoring system resources and in the rare occasion that an app starts misbehaving, it will give you a notification and the option to kill it. Otherwise letting the OS handle things itself is the best option. I've been using computers for a very long time and idea of leaving apps running seems counter-intuitive, but in my experience there is no reason to not trust what Google says about the issue.

i am also having these problems but im on honeycomb
i dont have any task killer installed but i installed one last week to check if my memory was leaking or if the rom was just rebooting

Great stuff here. Thanks for all the info. I think it was the random reboot since it did seem to happen most often when i was putting the nc in to standby.
Lots of good stuff here. Gonna miss the little green widget on my home screen, but i guess google knows best...

well i installed honeycomb preview v2 on my eemc from samuallhaff and it seems to remove this problem
i suggest you switch to his rom if you want the memory leaks to stop

Don't confuse "memory leaks" with "weird wifi sleep reboot bug".

Random applications

Can someone explain to me why I always have different applications that I didn't specifically start listed in my task killer? I am trying to get a handle on the battery life of my CM7 14 NC. I am pretty new to android and have a hunch that it is something simple that I am missing. TIA.

No one else sees applications running on their NC that weren't implicitly started? Sometimes I look and twitter / facebook will be running even though I didn't start them.

That's pretty much how android works, and it's also the reason why you shouldn't be using a task killer...

As has already been implied, don't use task killers. Apps start up and shut down on their own and Android has a built in 'task killer'. I found that when I was using a task killer, my phone ran at maybe 10% faster (due to less running on the ram), but the battery life actually was worse by a good margin. IMO, the Nook runs really well (especially if you OC it) and the battery life can better be controlled in other ways. Turning it off when not in use, unlike a phone (because you need it on to make a call, of course), will save a lot of battery. Also, SetCPU can be used to set profiles, they will save you on battery a lot. Disable auto-update and notifications for apps unless you really need them. use the power control and set it to where you can turn the brightness down low on the fly and keep it down unless you need it up. Sure, the screen looks beautiful when bright, but unless you're playing a game or watching a video, you don't need a bright screen.
Sorry for the rant, hope maybe it helps a little. Also, the more updates we have the better battery life will be.

Thanks for the heads up on this. I had not read that article before. I will uninstall the task killer and see what happens to my battery life. The other suggestions about turning off auto updates makes sense also.

Donot use setcpu or set profiles with cm7!

why not? I know it has built in monitoring, but it seems to me they work together.

cm7 already has profiles built into it under the cyanogenmod settings in the settings app! if you run both you are running the same thing twice and wasting both performance and power.

Uninstall and reinstall the modded launcher? I'm not familiar with it, so I really have no idea what the problem is. Does your phone lag anywhere besides the launcher? If not, it's probably the launcher itself.
As for an automated task killer, that is useless. Android (Linux) manages ram differently from Windows: it loads things into RAM so you can use them faster, and it kills things when it needs more space. This means that RAM is being taken up by essentially background processes—no CPU cycles are being used, and no battery is being drained, they are simply held in RAM to ensure later usability. Killing these applications, even while not in use, simply makes Android launch more apps to utilize free RAM in the background. Therefore, by closing them, you're forcing Android to open more, which consumes CPU cycles, drains your battery, etc.
If you're interested in making your phone more responsive, and have been looking towards memory management to do so, I would strongly suggest using the 'V6 SuperCharger Script'.

I use the MegaRam setting, which leaves plenty of memory free at any given time. I believe this is what you were wanting to accomplish with the task manager; however, again, Linux does not work like Windows. It has amazing benefits, though. Give those links a look.

That was awesome dude!!
nice post!
hey soudy1994 try the above post, i was gonna post that but he got it
topped with some extra easy tutorial !
These may also help you in boosting your SGS !
Build.prop tweaks (only if your ROM support for build.prop & init.d).
SAS Tweak.!
i think the above tweaks may have Juwe's Ramhack,i recommend go through em once and if the ramscript is not present you can have it, use the script manager (from the above tutorial )if you are a newbie !
I have phone patched with SAS tweaks+Juwe's script !
and finally would say try Jetpack ROM it has SAS tweaks built in and Solid kernel based on CF-root (semaphore)!
try my sign !
