Hi,
some of the applications does not have a exist option (maybe i didnt figured this out!). in this case how can i close them (i.e. can i do that by using back button).
I can press and hold the home button to see which applications are running and switch between them. but this does not allows me to close them.
please help

This has been answered many times before, but just to make it easy, you can use apps from he market. Personally, I've tried TasKiller and Advanced Task Killer. The latter I find to be the best.

HI,
but the problem with the advanced task killer is it gives huge list (i.e. I have not even started them.. i think it gives a list what ever i got in my program list)
for example, if i press and hold the home key i will icons of application i am running, however if i run advanced task killer i will get morethan what i have in previuos method.
i maybe doing something wrong.. but cant figure it out. please help
thanks ooo7
Yes,
I do have the same issue, there are a lot of applications listed which I haven't opend before.... I also want to close applications on a regulair base.
It seems the hero will slow done a bit when having a few apps open, which ofcourse is logical.
Advanced task killer lists all the processes that are running.
All devices (Mobiles, PC's and PDAs) have processes running that you haven't opened. these are the OS, and other apps that need to be running the whole time, like Gmail (or you dont get any push mail), calendar (Or you dont get any reminders), messaging, and many more. this is basic stuff and you need to understand it. just cos you haven't opened it, doesn't mean it is not running.
try opening task manager on a windows pc, and most have 20-30 processes running. Did you start all of them?
Also, holding the home key does NOT show you running programs, it only shows you the last 6 programs YOU accessed. Android has NO way of showing you what processes are running without a third party program. (or not that i know of anyway)
gotta agree with jamesking420 though, advanced taskiller is the best of the bunch at the moment.
Android closes applications when it needs the memory, but until then it keeps them cached in memory. So unless you hit some sort of bug, there is no reason to manually close applications. How did you get into the habit of manually closing applications on your cell phone, anyways?

probably from years of dealing with the antichrist of Mobile operating systems. Otherwise known as Windows mobile!
From what I've learned begin new to Android is that it is self monitoring. It will automatically close programs as needed ulike WinMo devices. You can just hit the back button or home button. It might store in the cache but the device will shut the program down as it is not needed.

Truly idle apps won't affect performance, but misbehaving apps still cause problems. Ex: Peep drains the battery in no-time when it has no account preferences and thus can't possibly do anything useful. Give it valid twitter credentials, or kill it, and the battery lasts a lot longer. I.e. if you don't want to use twitter you either have to kill Peep every time after boot, get rid of it completely, or connect an external battery-pack

rught, and if you add the android 'Task Bar' widget you can see, how much memory is free. You can also observe, that there are changes, because the operating systems frees memory by itself.
As others have written, there is no need to manually interfere, plus, if you switch off your device from time to time (I do it every night), you'll probably never have any problems with resources.
The known speed issues, that some users experience, should be solved by HTC and not with extensive use of Taskkillers and alike ...
Is there anyway of stopping peep and other things i don't use from starting up automatically?
I hear about people using different taskiller apps and now I have been reading that these apps are the cause of some problems and that the phone "knows" when to close apps if it needs the memory.
So what is the verdict??? Are Taskiller apps evil or necessary or do they have any value at all???
I use Taskiller. It's a great app but I have to admit, I wonder about its effectiveness. I tend to 'close all apps' if there are a lot running but I've found that this often causes more problems than it solves. As an example, I use the footprints widget on one of my screens. If I close the footprint app using Taskiller, sometimes it causes the whole touchflo process to terminate unexpectedly. I've also found problems closing processes with Taskiller which are related to the social networking/mapping features. If you know what processes to put in the 'ignore' list then fine, but closing some processes can hinder the phone's overall function.
Sometimes, however, if you want to close an app, there's no way other than to use a task killer. Take Peep for instance. No way to close it other than killing it. So yeh, task killers; generally unnecessary but sometimes handy.
Most applications do not properly handle shutting themselves down on Android. Android itself does not close many applications automatically, so a task manager is needed. How ever the automatic task managers have a tendency to kill system services as well and can cause a lot of problems on the phone.

I guess that is ultimately the question....is it really needed???
I used taskiller in the beginning but after I stopped using it I think my phone is generally more responsive and better. Why? Because it doesn't have to start apps everytime I change screen or whatever. However I do have taskiller to kill apps that crashes or similar just in case. I do not use it frequently though. Instead I let the phone handle killing apps and whatnot.
So in my opinion taskiller is not needed because the phone takes care of everything that's needed mostly.
advanced task killer screwed up my text messages so i havent bothered with one since. luckily the device is just as as quick and responsive without it. so my vote is 'a' and 'c'
My favorite has been Advanced Task Killer Free. It doesnt cost anything and doesnt get rid of any vital processes that Android needs, especially if youre using SenseUI. Also, I have seen noticeable performance increases afterwards. So yes, I would say it is needed.
I've been using advanced task killer with problems. It seems to do what it suppose to but it also closes the radio for some reason. The rx signal comes back but the evdo doesn't unless I do a reset... I even payed for the advanced task killer thinking it would have more options but only has a hourly function.
Linux has it's own scheduler which handles tasks very efficiently.
no its not needed. i use to use advance task manager and it totally screwed and lagged my phone. not to mention i wasnt getting my sms because of those apps...i stopped using it and my phone functions great. if i feel that the phone is bunddled up with alot of apps i previously opened, i simply reset it (i hardly do resets because the phone functions excellently).
so no to task killers.
I had Taskiller installed, but after initially using it, I found that I wasn't bothered to use it, but it was still there with the icon at the top of the screen.
I read that they can actually slow your system down, so as I wasn't using it, I uninstalled it and maybe it isn't but the system does seem a little more responsive now
Vince
i used advanced taskiller and it kept my phone awake even when locked/lcd off. that murdered my battery. i uninstalled and use task manager now with no issues. it is not as simple as dragging down the notifications bar but my battery life is fine now.
I've definitely found that there is pretty much zero benefit to regularly using a task killer. Other peoples mileage will vary of course, and I'm sure there will be combinations of applications that don't sit too well together and cause issues, but I'm pretty confident than Android handles resource management well enough for most users.
I do wonder how may of those who swear by task killers are also using swapper, as I can well imagine that swapper will cause problems with Androids own resource management.

Dave
HAHAHA guess you're not getting a clear cut verdict on task killers from this thread! seems like everyone has their own opinion....
There was an earlier debate on this topic. The thread is here... http://forum.xda-developers.com/showthread.php?t=569709&highlight=task+killer
and the android info is here (must read for understanding task killing) http://forum.xda-developers.com/showthread.php?t=569709&highlight=task+killer
They work well when set up properly. No reason to be closing widgets and programs on your sense ui that you use on a fairly often basis because it will take some time for them to load when you want to view them.
Leave the stuff you use regularly open and close the junk that takes up resources that you don't regularly use. Most of these programs have exception lists for a reason.
People that automatically end all and close sense, or their system dialer files will obviously run into problems and lag when all that stuff restarts at the same time.

Exactly. They are fine if you exclude ALL the necessary components, then just have a few remaining on the main page that you know can be quit. Advanced Task Killer has been fine for me with their 'ignore list'.
i found that since ive stopped using task killer m battery life has improved quite alot
now i leave all the work to the android system
I have had the hero from day one and have had taskiller installed for about as long. I DID use it but do not now... and have no slow downs...
how?.......
custom rom....?
service which frees memory?
no...
Simply press back to exit a program and not home... if you press home the program most likley will not catch the button press and close. click back to exit and the program closes properly.
Press Back ....... this ISNT an iPhone with only 1 button.

I'm going without on this hard reset. On the last go around, even with disabling native sms app and using a 3rd party I was still getting the 100% awake time issue on the sprint hero.
FWIW, On a sprint hero make sure you ignore htiqagent, iqrd and omadm. Killing these will cause a radio reset, and ignore htcsense if you are using sense, which btw you can disable by removing its default setting in settings-apps-manage apps.
I think it is safe to say that I'm pretty ignorant about Android/Linux/etc. Nevertheless, I have Advanced Task Manager and I like to use it. I do use it judiciously, only ending certain programs/apps yet leaving most of that business to Android. And, of course, I use it to end the program itself.

Im using advanced task manager to kill tasks so too many are not running. I used it all the time with the mytouch. Now using it with new Vibrant
Question,
I have excluded TwLauncher from being killed when I press end all, or press the widget. but when i kill all tasks (except for the excluded ones) I has to reload my home screen. What other process should I be exclude from being killed so that it does not reload my home screen?
Thanks
the better question is what else did you kill? Keep killing apps often so the list is small and see what app it is. Even better would be to close the one at a time and go back to the home screen each time.
In all reality, with the amount of ram and how good android is at killing apps itself, taskkillers are not needed. Infact google does not recommend them.
Like previously stated, do not use a task killer. Uninstall, reboot and you will have no issues.

precisely.
forcing your phone to constantly kill apps only causes your phone to restart the services which were running in the background. While your phone is now being forced to RE-start those services it uses more clock cycles than simply leaving the services running would have done.
There's more than enough literature and evidence that task-killing in Android is at best useless, and at worst counter-productive.
So Samsung for whatever reason, decides it's a good idea to include an easy to access task manager with a giant "kill all tasks" button in TouchWiz. It seems like everyone I know, that has a Galaxy S II, has adopted a certain behavior due this. What they do is, every time they put their phone away, they will automatically go to this task manager and kill all tasks, before locking the phone. When I ask them why the hell they're doing that, the answer is usually something like "wasting battery blah blah blah" or "wasting CPU blah blah blah"... NO!
For starters:
http://geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
http://lifehacker.com/5650894/andro...ed-what-they-do-and-why-you-shouldnt-use-them
http://www.infoworld.com/t/smartphones/myth-android-devices-need-task-killers-609
http://androinica.com/2010/05/googl...-imply-task-killermanager-apps-are-pointless/
People that are doing this, educate yourself. And Samsung, well done for encouraging this.
Just because a task is in memory, doesn't mean it's doing anything, and certainly doesn't mean it's using up battery. If it's staying in memory, it's because there's no need to release it just yet. If you start it up again, it will already be there, and load up faster. The alternative is, you keep killing it, and every time you run it again, it will have to reinitialize and reload everything. Which option do you think is actually going to cost more battery?
The whole thing with people saying "oh no it's using CPU, i must kill it"... what?! If it's using CPU, it's probably doing something. Why the hell are you killing a process while it's in the middle of doing something? Do you not care about data integrity at all? It could have been in the middle of syncing, or in the middle of a write operation who knows.
If you run other applications and your memory runs low, then Android will close it. And it will close it properly, as opposed to you force killing it, denying it of any chance to clean up.
Obviously there are rare exceptions with dodgy programs. But most of the time, the tasks being killed are system apps, or trustworthy apps, properly written by Google or Samsung.
If you're not a developer, you probably won't understand the whole Android application lifecycle.
http://developer.android.com/reference/android/app/Activity.html
By force closing an application, you're not allowing it to run its onStop() and onDestroy() functions. This is where apps do all the clean up, releasing resources, unregistering things, closing connections etc.
Do you do this on your PC. Open up Windows task manager, and just kill any task that's using CPU. Or hell, just kill all tasks every 2 minutes! Good luck with that.
This has probably been said hundreds of times, but a lot of people i know are getting GSII's and I see them doing this constantly. It's stupid. Do you really think they designed the operating system so that you have to kill everything each time you touch it?
TLDR: Stop "killing all tasks" (unless theres actually something wrong) and well done Samsung for encouraging this. Just stupid.
Damn your right, I never used a task killer on previous android phones, but for some reason I have got into the habit of doing it now. So I'm going to kill that habit. Well noticed
Well according to the user guide (the full one from Samsung's website)... though personally I don't bother killing anything
Use the task manager › ›
Your device is a multitasking device. It can run more than one application at the same time. However, multitasking may cause hang-ups, freezing, memory problems, or additional power consumption. To avoid these problems, end unnecessary programs using the task manager.
1 In Idle mode, open the application list and select Task manager → Active applications.
The list of all the applications currently running on your device appears.
2 To close an application, select Exit.To close all active applications, select Exit all.
i like the placebo effect and stop telling me what i have to do or not to do!

For me, it is worth to have the clear memory option because I already faced the glitch or bugs program which cause my phone to run constantly at 1.2ghz and this will cause my phone become extremely hot. I can't see what application is running but for some reason, the cpu gone crazy. It drain battery in no time. With the simple one click button, I can closed the programs without need to restart the phone. Yes, generally I will let the android system to handle the application by itself but I still think it was a good moved by samsung to have task manager if we use it in proper way...

Well it's not all that bad, with 2 cores one core can easily come into a deadlock and the device will continue to function albeit much slower and consuming a lot of power, when this happens in the taskmanager the processes are listed red
Thanks ever so for much for this post I have just got my first Android phone and thought by doing this it would increase the battery life a tad but did kinda think it was a bit daft having a system that required manually killing tasks. Coming from a Windows 6.1 XDA Zest I am still getting my head round an OS that's doesn't require hours on Internet to work out how to do things.
Sad, but true, I was getting onto Android from Symbian, and first thing after I realised that I do not have option of killing all apps, I have installed the task killer and kept using it for like a week, then I've read one of the articles about it, that its wrong, and that Android is not working as Symbian nor Windows, so I realised that I dont need to do that... unninstalled it and not using it at all since
You don't need Task manager / killer if only all android applications are developed by good programmers that implement Android application lifecycle properly.
The problem is not all applications are developed this way. Some application may buggy / in beta stage that still consuming processing time even they are in background.
Task manager is still useful to close nasty program manually. But I do agree, auto-kill is useless and can cause battery drain and system instability.
Yep .. it's mostly services what eats battery. And there is poor control over that. It would be interesting to see what service was active at what time, or even how much battery did it use. All battery discussions are about guessing what is running in the background and how often and how much. We should not guess such things.
As far as I'm concerned an in built task manager is just as important as an in built modem right now. There are far too many unstable applications out there that hang up and Android can never fully deal with them(despite what research may or may not have been done in the past).
I have a few games installed on my S2(namely Pool Break Pro & TNA iMPACT!) that crash quite often and require the use of the task manager to manually end those programs(they are in the task manager highlighted in red when they have stalled).
However, what I will say is that the button to clear memory in the RAM manager really shouldn't be there at all. The task manager alone is more than enough to manually exit necessary apps that crash and stay open for no reason.
I like to have the ability to close programs easily at hand. It gives me better control over "rogue" apps. I only use it for a few programs though, like the Engadget app. It seems to be poorly coded, often using 40-50% CPU when running in the background.

Lol yes. Not to be taken too seriously.
Force closing apps with the task manager when somethings wrong with the phone or closing broken apps makes sense. I'm just talking about people that instinctively press the close all apps button every time they use the phone for a second. It's just silly. Basically doing what those automatic task killing apps do.
I use to kill opera everytime i'm done with browsing because even in idle mode the phone gets very hot when opera runs in the backgtound. But after these explanstions i stop force killing every app

If a program is badly written and won't stay idle, then kill it.
I am very selective about what I install, and never kill or need to kill anything.
You have 1 GB of ram on this phone. If you want best battery and speed, don't kill anything. loading a running app from ram uses less power than starting from scratch and booting it from nand, then starting it up.
So if apps are well written, don't kill them. If stuff stays around causing drain, kill it individually but find a better app
This thread is spot on... for the most part. Like Pulser said, there are apps when idling/cached, cause detrimental effects like the one I detailed here causing your phone to stay Awake constantly and draining battery:
http://forum.xda-developers.com/showthread.php?t=1094666
ATK isn't the most elegant method, but it allows you to put everything else on ignore and have it actively kill the apps that love to stay cached and cause issues even after you've exited out of them.
Is there a way to "lock" some apps into a memory so they never quit by the android OS except if I would decide to?
Sent from my GT-I9100 using Tapatalk
You have a valid point, but most of the time those apps don't do anything critical that it would hurt to interrupt. I usually prefer to exit them normally, but sometimes I just kill it, like when I forgot the Messages / Internet open. No need to paranoia though, leaving a few open won't kill your battery.

That's exactly what I needed. There are some apps, like SetCPU, TB, Root Explorer, which can be added to SuperUser authorization and it won't get killed by anything unless someone manually kills it. I'd really really like to know how to add an app under SuperUser or anything which will do the job to add the app in to the OS and which can't be killed by any Task Killer or anything.
Besides I also hate those Task Killer apps, they are meaningless unless an user do nothing regularly with his/her phone.
I've no Task Killer installed but once I used the built in Memory Clear feature and next day my schedule app got closed. From then I never touched it. But one thing if RAM usage goes above 400 MB I think sometime its good to clear the memory as it will help to refresh it. But Samsung should had put the Memory Clear feature more precisely.

I develop Android apps so I'll explain why a task killer isn't needed on an Android system.
Activities Android apps use activites to preform tasks. For example, if you use a file manager to send a picture via email, the file manager calls the send activity within an email app, passes the file name to it and the email app sends the picture.. not the file manager. This will result in seeing the email app as "running" even though the user didn't actually launch that email app.
Smaller apps Using activites helps developers design smaller apps. A file manager app that contains every bit of code needed to do everything a file manager does would likely be so large that no one would want to install it. Developers know that an android phone more than likely has an email app so there is no need for the developer to include email code in his/her file manager to send a picture when he/she can call an activity in an existing email app to do the job. This results in a smaller file manager app since there is no need to include email code or any other code for an activity that can be done via an app that is already present on the phone. This also alleviates redundant code. When you install an app outside of the android market, also known as sideloading, the file manager app calls the package installer (already present in Android) to install the requested app.
Running apps vs. cached apps The "Manage Applications" list included in many android devices lists running apps as well as cached apps. Cached apps don't use any CPU or battery, they're cached so they will load faster the next time you need them. Killing cached apps results in those apps requiring more time to load the next time they are launched.
System management By default, every android application runs in its own Linux process. Android starts the process when any of the application’s code (activities) needs to be executed, and shuts down the process when it’s no longer needed and system resources are required by other applications.
* Android is hard coded to automatically kill a task when more memory is needed.
* Android is hard coded to automatically kill a task when it’s done doing what it needs to do.
* Android is hard coded to automatically kill a task when you haven’t returned to it in a long time.
* Most services (while possibly running in the background) use very little memory when not actively doing something.
* A content provider is only doing something when there is a notification for it to give. Otherwise it uses very little memory.
* Killing a process when it isn’t ready only causes it to have to reload itself and start from scratch when it’s needed again.
* Because a task is likely running in the background for a reason, killing it will only cause it to re-spawn as soon as the activity that was using it looks for it again. And it will just have to start over again.
* Killing certain processes can have undesirable side effects. Not receiving text messages, alarms not going off, and force closes just to name a few.
* The only true way to prevent something from running at all on your phone would be to uninstall the .apk.
* Most applications will exit themselves if you get out of it by hitting “back” until it closes rather than hitting the “home” button. But even with hitting home, Android will eventually kill it once it’s been in the background for a while.
If you see an app running that you didn't launch, it's most likely because an activity within that app was called by another app to perform a task. If you kill the app you didn't launch, the system has to relaunch that app in order to complete its task. This is why some people kill a task and then see it immediately running again. Constantly killing that app creates a situation where the user is battling the system resulting in wasted system resources.
Android is Linux Android is not a Windows-based OS, it is based on Linux. Many of the apps you think are running aren't actually running, they're cached, this is typical with a Linux operating system and is much more efficient than other systems. Cached apps don't use any CPU or battery, they're cached and will load faster the next time they're needed.
Let the system manage resources.

I have had many apps running and my system gets slow, and when I look to the available memory is super low like 25mb. In order to get the system nice and smooth I used Advanced Task Killer to close all those apps that don't automatically close like you say. Maybe its just my NC, or maybe its a problem with the apps I used, but I do find it useful to use a task killer. I can select which apps to close so I normally close games, media, etc. The other system and necessary apps I leave running.
In my experience with the NC having a Task Killer has been better.

I am sure that the previous developer, koopakid08, is correct about the way Android handles memory and apps, and I really enjoyed and appreciated his detailed post. I just have to believe what he says is accurate, as others also say the same thing. But I totally agree with you that using a task killer absolutely helps my Nook Color run better whenever the available memory gets below, say, 75mb. Without killing tasks, my Nook Color may not respond for many minutes, or may self-restart on it own. Perhaps there is something about using task killers after all.
