Advanced Task Killer Questions please

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.

Quick question on using Advanced Task Manager

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.

RANDOM APPS OPEN ALL THE TIME *curses at phone*

Hello XDA, this is my first post. I've had the EVO since launch and I just installed the early rooted Froyo build when it was released but that's irrelevant because this problem was there from the start. I use Advanced Task Killer and see that random apps are opening without my prompting, things like Google Voice, Gmail, Voicemail...very annoying.
On another note I have much more available memory running this unofficial Froyo, even with these apps opening at their will, than I did originally. Thanks for that, XDA.

Since you're rooted, you have two options that I know of.
Download Titanium backup and when you click on the backup/restore tab, you can click on the apps that frequently pop-up in ATK (e.g., voice dialer) and chose to freeze them. This will render the app inoperable. If you have any functional problems you can simply defrost it.
If you find that you're frozen apps are not causing any problems and you don't use them, you can then uninstall them with root explorer (or another file explore with root access).

I have Titanium Backup and didn't know I could do this, thank you very much. is there any way I could stop the apps from opening without rendering them useless?

Get Autostarts. Configure it.

If I download Autostarts, will it stop my apps from opening by themselves even if I use them occasionally?

I know StartupAuditor does, but its a paid app...

I suppose I'll go for that then

Some of the apps need to be running in order to work as they should. Unless and app is chewing up a lot of CPU you won't notice a drain on the system. A lot of these apps have services that are running constantly so they can poll the system for updates in state, say like receiving a text, call or email. Likely many of the apps are set to auto-refresh so they have to start every so often to complete a task.

ITS FINEEE!!!!
Ok, I am pretty good with computers and electronics but not so much on Android.
But I have done research from people who do know android, and will tell you what to do.
1. Don't use a task killer!!
2. Android is based off of Linux OS.
3. When you turn your phone on and launch Advanced task killer, all of your apps will most likely be "opened" however they are not running.
4. The way the OS works is by technically having all of those apps opened, but they are most likely not wasting CPU or battery, so don't worry about them, thats the way everyone's android device works.
5. Using a task killer is bad, because when you shut down the apps, eventually you will get a lot of force closes, because apps that were supposed to be open were closed and their for not running the way they should.
6. Apparently the OS runs better with more apps open, however its not like windows mobile where if you have 3 apps running at once, it will make the phone slower. Android is designed to have all apps "opened" Again it does not mean they are running.
However,
If you notice that a certain app is hogging CPU or causing poor battery life, delete it, but if you really need the app, then you can use the task killer to kill that app.
And no if used a task killer, your phone will not be ruined or anything.
Hope this helps.

agreed, don't use a task killer, they are essentially useless and just end up causing problems on the evo
What your seeing is most likely the app 'process' so it will actually work correctly.

[Q] Why do apps keep popping up in my "Advanced Task Killer"?

I don't know if this is an issue with android.. or galaxy s... or "Advanced Task Killer".... but apps keep popping up after i "Kill" them....
when i say apps pop up... i mean random apps that i have not touched...
for example I never touched the Visual Voicemail as i don't have use for it.. and amazong mp3.. the list just keeps going ...
i don't know why it keeps reloading after i "kill" them..i did google this problem and could not find any one else complaining... maybe i didn't do a good job of searching... this is wayy too frustrating
is there a "Fix" for this?

well first you shouldn't be using a task killer. Second they show up there because some apps run in the background occasionally without you even opening them.

Because the apps are doing stuff and you keep killing them so they restart. Stop using a task killer and let android handle the running programs like google programmed the os to do. The google programmers are really talented I promise.

As said above. Apps auto run in background. Android deals with this efficiently, best not to use a task killer

Don't use task killers.
It's really that simple.

Task killer is a no no for Phones with 128+ RAM

Most stuff needn't be killed, but T-Mobile includes some bloatware that has absolutely no right to be running at all, much less all the time (hi, daily briefing). The "don't use a task manager" meme is fine for a stock android phone where presumably you're only installing things that you actually want to use, but when you buy a branded phone you really *don't* want the carrier garbage running all the time. At best, it sits around doing nothing until Android kills it on its own, but at worst it can drain your battery life and cause instability.
The only surefire solution I've found is to actually remove the offending bloatware using root explorer or titanium backup.

^^TL;DR Remove bloat, don't use a task killer.

Ok, I'll ask if no one else will, why not run a task killer? What is the downside?
There are any number of applications on the phone that I literally never use like Amazon MP3, Slacker, and Visual Voicemail, why would I want to leave those running when I have no use for them, and there is an easy way to kill them off when they spawn themselves?

I think its ok to use Task Killers for occasionally stopping apps that are giving you issues (running slowly, frozen). The problem with using Task Killers is that it can make your system unstable, it can mess up widgets, and Android doesn't really need it. Android will close apps on its own when it needs more memory . Most apps, if programed correctly, will use little to no battery power when idle in the background. It can take more battery power to start up an app again rather than opening it from idle.

We're finding more and more that on higher end phones, such as the Vibrant, when a task killer is running the Android OS isn't being allowed to control the apps to it's full potential and some of the task killers are causing problems. After we remove the task killers, problems can occasionally be resolved. Not always, it's just something we're seeing. At least in my store and when I can in to support.

Because when an app is running in the background, it uses practically no battery. Most of the time it is not using any processor clock cycles just taking up some ram space. You don't have to worry about the ram being used because android will automatically end apps when it needs more ram. A lot of the time, ending an app via task killers will actually slow the phone down because when you go to open the app again it has to totally reopen rather than just awake from an idle state. Android 2.2 is even better at managing background tasks and running a task killer will almost guarantee a slower phone.

VVVVVVVVVVVVVVV

Smart Bars not a bad one that you can start up and kill a task that wont exit out. However i wouldn't use it to "free up RAM"

When you start up the phone on stock rom w/ all the bloatware you have like 20+ random apps already running by default. If you ran a quadrant test now your score wouldn't be as high as if you killed all those apps then did the test. I went from 1900 to 2250 by killing all the apps. Not a huge difference but personally I don't like things like Slacker or GoGo running in the background when I never use them.
I don't like using task killers though, I just wish all these stupid apps wouldn't start when the phone is booted up. It can really make the phone slower. Killing all apps + lagfix means load times are almost non existant. Having all those apps running + lagfix means you will get some stutters in load times.

Task killers often show cached apps. They are not running just on stand by until you open them.
Sent from the best phone from TMO... Vibrant

There is an app called "Start Up Auditor" It disables any app you want (yes including the bloatware) Form starting up when you boot up and randomly while the phone is on.
For example I have all my bloatware that I don't want set to do not start at boot up unless I physically choose to open that app.
Better than any task killer out there. So you NEVER have to worry about the bloatware other than it taking up some memory.

That's really the best explanation right there. It explains just why Android does what it does.
Sorry, no tl;dr for the lazy.

I had my task killer on auto kill cuz i was frustrated..... but i'm gonna go download that "Star up Auditor"... sounds like the most efficient way... since i actually do use Slacker..
anyhow..thanks alot guys for the suggestions..

Why shouldn't use task killer?

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.
