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.

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.

I have advanced task killer installed and even after I kill all apps and my phone is just sitting some programs still start up and run.
Such as sprint navigation. It always seems to be running even though i dont use it. I do have an icon for it on my home screen.
Also my visual voice mail is always running even when i have had no voicemails.
Does anyone know why these programs keep running and slowing down my phone?
I don't have the answer to your problem, but I can confirm that you are no the only person experiencing this. I have yet to use Sprint Nav since purchasing my Hero on the 11th, and it always finds a way to creep back onto my running programs list.
I've seen that Sprint Navigation opens with some apps that use GPS, it's weird and I don't understand that, but it doesn't open "on it's own" for me, just with some GPS based applications.
Hi there,
I've seen this also, through using Advanced Task Killer and Task Panel X also. Here are some of the ones I see that pop up a lot in my situation. Please note my comments after them, as sometimes they're fairly vital to keep running.
-HtcIQAgent - HTC something, leave running as negligible RAM gain if killed.
-OMADM - not sure, but think this is a system app also
-Peep - can't kill this at all without it coming back, in ATK anyway.
-Stocks - will keep coming back too, OK to kill tho
-Footprints - also OK to kill
**app.vnotes - this is Visual Voicemail, DONT kill it unless you're OK with not getting notifications!!
**Mail - default Exchange mail app, DONT kill unless you're OK with not getting notifications
**Touch Input - System app, can kill but phone feels a little sluggish if done, so I normally have this one excluded
**providers.htccdma - System app, negligible gain when killed. Leave it be.
This isn't an exhaustive list of course, but some of the apps I've commonly dealt with using both aforementioned apps.
It started driving me mad. If I minimize browser, I can't be sure it won't close. Not only minimizing for longer periods, but short ones as well - wanted to reply an sms when a page was loading, but when I got back to it, it started over. And all the loaded tabs were gone! Saving states my ass, it takes time to load a page from zero and only the active browsing window remains. How to make this "multitasker" multitask?
does this also happen if you return to the browser by holding home?

Yes, that's the only way I switch betwen apps.
Have you installed the 'system-based' taskiller mod by any chance (you know, the one that was announced here that automatically keeps memory free by modifying the default thresholds for killing apps)?
If so, I reckon that's the issue! Either that, or you have too much running, so popping the browser into the background makes it a background task and it gets killed cos you're really short of RAM.
Let us know if you have used the tweak though...
@kengdong...
it doesn't matter how you change the apps.
For android it's the same, whether you tap an icon on a homescreen/list or whether you select it from the "task switch" thing... all that does is listing the last recently used applications but still tapping them results in the same internal action.

I've had pretty much the same issue since I got the phone back in November (I guess I've just gotten used to it by now). I'm never really sure when I switch back to the browser if it will retain the page loaded and any other windows, or if it will reset, close the other windows, and have to reload the active page. I'm on the stock Telus ROM, no custom ROM, not rooted, no tweaks, nothing extra (I've been waiting patiently for 2.1 to come out before messing with custom ROMS).

No, I have stock rom and I have never used any task killer or related app / tweak.
And I don't run too much stuff.. only music player, messaging and sense's facebook perhaps. If music player is paused, why can't it quit it instead... I prefer multitasking of my past htc s730 which had like 7 megs of free ram after booting.
Even after a hard reset, this behavior remains.
i dont know.. it works fine for me....
1.. maybe there is a setting in the browser.. to always refresh.
2.. you have a repair issue.. Need to take it in to your local service provider repair center. Let them see your issue.

Come on, it's no hardware issue. Most of the time the browser stays, but u just can't be sure about that because it sometimes just closes. I think that it's an issue with Android's STUPID memory management, which also has a scheduled "quit all" script.
Yesterday I opened up a few articles on the browser and decided to read them later. This morning they all remained and I was pleasantly surprised I could read them. This very moment, though, they are gone by now even though I haven't quit the browser - probably that 'quit all' script kicked in.
There could be something in settings, where you could chose apps which would not close ever unless quit..
I would love if Android apps were quitable without any automatic mem management.
Suggest to grab AutoKiller or MinFreeManager, which are just frontends to Android's memory management (also they reapply settings at boot time, as the system file that's being modified is reset every boot.)
See what your current settings are, and lower them (e.g. use "moderate" preset). Just search XDA for autokiller or minfreemanager for more info.
Pressing home should only move that application to the background (pressing back should close it).
If you are pressing home and applications are still closing then there must be a task killer of some sort in place closing it for you.

No task killers, tasks dont neceaarily close, its juast that u cant be sure they will remain in memory.

Yes - it's the standard Android process management rather than a 3rd party task killer.
I guess the browser is given a low priority and is one of the first apps to be killed.

Hi
Ive just got this app (really to save myself some battery time)
On launching for the first time it presents me with a whole bunch of stuff including my clocks
Now i'm sure this maybe a pretty dumb question but if i kill the htc clock App will that stop the time and weather updating correctly? (i have my weather set to update hourly) and also if i kill any app like K-9 or Peep (that i have an update schedule set for) will it stop that schedule till i manually launch the app again or will it auto launch when it reaches the sheduled update time?
Sorry for the (potentially) stupid questions
Cheers
The only thing you're going to achieve with using a task killer, is lowering performance and causing even worse battery drain. If that's what you want to do, fine, but otherwise, I wouldn't bother if I were you.
Here's why:
Android's memory management is nothing like Windows Mobile. Applications you've finished with are MEANT to stay in memory until they really are completely finished with, and just because YOU aren't using them, doesn't mean the phone has. If they've been inactive long enough, or some other program needs the RAM, Android will tidily close them down.
If you close them prematurely, then Android will have to load them back up again, so that whatever was using said program's services, can continue to function. This noticeably affects phone performance, and puts an extra load on your battery. Do you REALLY want to do that?
I'm not using any task killers, and my phone runs great, and battery is up to 2.5 days.
Hmm interesting, i might try that, im killing all instantly and repeately, thanks for the tip

Thats correct.
I installed it on the phone, and the battery was empty the same night
Uninstalled it, and all works fine now.
Greetz.
would an app like task panel work?
you can add apps that are system apps etc to the ignore list and have apps such as games on the force to kill list or is it just best not to have any task killer apps installed at all?
its strange that there are so many task killer apps and its bad to run on your device. There must be some reason as to why there is an app for this purpose?

They exist, because people think memory management on Android works like it does on Windows Mobile. It doesn't, and never has. Think if it like the so called "memory manager" tools you can get for XP that claim to be able to free all your RAM and speed up your system... Every single one of them is nothing but a placebo designed to part you from your cash, and often end up CAUSING problems, just like task killers on Android do.
Avoid them.

Guess thats a good enough reply lol
task killers can work fine, but you need to know what is running and what is using it.
for example, if you have the music widget on the homescreens, then the music player process will be opne in the background.
likewise friendstream will keep people, facebook and twitter open in the background.
if you kill those processes, they will just get opened again.
As long as you are careful, using task managers will not decrease battery life, you just need to know how to use them properly. randomly killing everything in the background is NOT the way to do it.
and you should never close clock if you want your alarm clock to actually go off!!
Might be worth making a list of what apps should be ignored and what apps can be forced killed?
When i had an app killer installed, i used to only force kill games and sat nav apps, the rest i asked it to ignore but after reading this thread, i decided to delete the app killer app =)
Ive put a bunch of stuff like clock, weather, Peep and facebook etc on the ignore list and have used the task killer to only kill off frivolous apps like Spark (for xbox friends) streamfurious, photos etc...Nothing Major!
I unhooked my phone from the power at 7:30 am on the 13th April, its now 16:36 on the 14th april and it still has 30% of the juice left, and i always have wifi and mobile data connection on too...phone is always left on with facebook connecting ever 4 hrs and peep once a day and mail set for every 2 hrs (besides which i do check and update them manually a couple of times a day)
I'll try all this without task killer installed and test how long the phone can run before charging
As you say, it could well be a combination of the battery coming up to speed and a placebo effect.
However, surely it cant do more harm than good to kill an app like Spark !
However, im no Phone Genius so im sure someone will soon tell me that im completely wrong
But so far so good....like i said, ill test things without task killer installed
I've stopped using the task killer now and my battery life has improved very noticably.

im not so sure about this.
im using a task killer when i want to close the browser or something using internet, as we all know internet drains a lot of battery and even if the browser or market is in the background it still probably has some active connections = draining battery

If you want to close fast the browser or any app, you should have a try at taskOS and launch it with the search key whenever you want...
Binned this app in favour of Juice defender, my new battery saving app of choice, seems to be working as it should too...nice

but then that works pretty much like a task killer
can anyone correct me about the apps i.e. browser using internet while not active(in background) is this true or not? of course having the sync/updates turned off
Task killers can be handy for those times when apps seem to have crashed but aren't forcing close. for example, i've had times where ebuddy just doesn't want to even try to sign in. Task kill it. Try again. all is well. And last my internet browser wouldn't let me click any buttons. Again, killed it - restarted - all is ok.
I've had to use such an app countless of times due to unwanted/unneeded apps running, hanging FCs and black screens, checking/closing net related or sensor using apps, and numerous times when 300KB apps wouldn't install citing 'low memory' when I have more than 70MB free, but it was the RAM being near full causing FCs in apps like Market, and halting the installs. I only use Androids built-in TaskPanel widget for this though. Everything routine is set over to the ignore list so that I don't accidently hit and close that (single hit closes the app). Additionally I use this app to check and to switch to an opened application that is running (when it's not in the recent list).

This is the route I've taken naturally. I'm using jkAppSwitch on my longpress search key, mainly used for switching but can be used to kill problem apps.
Full task killers are being proven to be useless on the Desire.
I would recommend using an app that monitors the cpu usage(watchdog etc.). This way your can see which apps put a drain on your phone.
Thank you for the information. But I do notice a considerable improvement in battery power with Advanced Task Killer.
I hope someone can provide me an answer.
I downloaded Advanced Task Killer Free, and things like Sprint Navigation, Facebook, Voice Dialer, etc, the list gets 20 programs long after about 15 minutes... this makes no sense.
Can someone who has used Android longer please explain this to me? It seems that this OS needs much more babysitting than even WM, if it's really auto-starting all this crap for no reason.
It seems like all of the applications you described are system apps that were on the phone when you got them. They may be set to automatically run. I know you wont be able to remove any of them without the phone being rooted and having su access - but i may be wrong.
When you close them, it seems like the OS is just automatically reloading them.
Careful when you kill apps, it could cause some unwanted issues.
So many of these programs have nothing to do with day-to-day operation... this is bizarre.
Does Android supposedly have built-in memory-management? IE, you exit the camera app, it eventually FORCE closes it? So far, I haven't noticed that behavior at all. That's what caused so many issues on my old WM HTC devices.
Android does have built-in memory management. It is how the OS was developed.
If you have a program running on your screen, it will use whatever amount of memory it needs in order to run it.
If the program gets pushed into the background, but is still running, it will still use the memory, even though another program is being ran using up even more memory.
Having free memory will not make the phone run any faster. Eventually the program in the background will close if not used. It will also be force closed if the system is in dire need of memory.
Android knows when it is need of memory.
There are several threads already which explain memory use if you search. Since I'm using my phone I won't go into detail but I will say that task killers are not recommended. It's much better to let Android manage the memory and processes.
My personal experience bears this out as I had a lot of strange issues like losing wireless connectivity when I was using a task killer. Now I let Android handle things and my phone runs smooth. Using a Sprint Hero with Fresh 2.1.2 ROM.

Interesting... all my friends who use Android have task managers... Most engadget posts mention that too. Hrm... I guess I'll make sure auto-kill is disabled and just watch and see how the OS holds up.
I just got the phone this morning and was killing apps left and right. I started to get a lot of Force Close errors.
I rebooted the phone which would clear the memory anyways and I'm letting the OS handle everything now - Havent had any problems since.
good luck!

Honestly, if you are worried about a particular program running away and have reason to believe it, sure a task manager/task killer can be handy for that one program but historically, giving people task managers on Android causes more problems than it helps. Voice Dialer is your phone app for example and at the CDMA Hero forums, we've seen the phone do some crazy things when we removed it from the phone right after we got root (turns out that thing is hooked to more than just the "making phone calls" feature).
All that said, it's quite informative to google around about android's method of memory management. It's kinda cool!
I had a hero, and it least made it through the day. The Evo is way worse. I have no idea why some things run in the background that I've never used and have no reason to be running in the background. I'm using ATK and Auto Task Manager, which kills app once your phone goes to sleep. You just have to know what apps you shouldn't be killing. As a rule of thumb, I didn't kill any native google or HTC services. I did kill all Sprint services. Following this guide as well:http://www.mobilecrunch.com/2010/06...attery-life-and-what-this-says-about-android/
here is why you don't really need a task killer.
with that, i can say that i do have one but, i don't have any autokill going. i only use it as a last resort to kill things if i have like multiple things producing sound at once.
Honestly I can tell you from experience, that sprint bloat wear will launch on its own all day long. Even if you set ATK or AMM to nuke it, it eventually will cost more batt. in the long run because of the system resources required to launch and kill over and over again. The only way to successfully deal with the issue is to rm the crap, which requires root.
