Hello guys;
just received my phone yesterday and i have a question regarding open programs
does the back button until home screen close the program or it still run in memory?
some people advise the use of task killers to kill unwanted tasks to save battery
while others say that Linux is handling this automatically and using task killers is no use
some people claims that after they stopped using task killers their battery life was better
i am new the Android as i am an ex WinMo user so please enlighten me
Thanks for huge efforts guys
Yes, they are. Android does a poor job of managing tasks, even to the point it auto starts like everything in your phone and very few of them turn themselves off.
You can manually manage them in applications, running processes, but task killers are so much easier.
I have owned 3, and the one that is easiest to use, that I have never found a bug with is Advanced Task killer (Little green droid icon). The purchased version is expensive, but worth it as it gives you one click widget to kill tasks.
Advanced Taskiller is known for crashing the home screen and stopping vital system services requiring a reboot. I own the full, and I have no use for it.
Okay, let's see how many questions I can answer here....
First of all, using the back button does not close the program. Neither does the home button. Android does handle this natively, but it does so automatically. It doesn't matter how you exit a program, it stays running until it needs to close. Whenever too many apps are running, slowing the system down, it will close the older ones as needed. All automatically. Nice, huh?
Task killers let you do this more aggressively, or manually. You may want to do this if you want your system to be "extra" fast, or to save battery. Most of them have extra features, too, like switching to running apps, or uninstalling them, etc. Beyond that, you don't need it. Some people say that task killers actually drain battery, but in my experience, they help slightly. And they do improve performance slightly too--as long as you are smart about not killing the wrong apps. (HINT--if it's a widget or a background service, never kill it)
So really, it's up to you. Get a free one, or a trial, and try it out, see if it makes things better or worse. Just take into account the learning curve before you give up on it--you have to exclude widgets, background processes, and maybe a couple other apps, too... takes a bit of trial and error to figure out which apps get bugs when you kill them.
It's not necessary but highly recommended. I use Taskiller the paid version. I mainly use it to kill apps that start to have problems and to kill a lot of the apps that boot with the phone.
on G1: i use it every time i reboot, because on boot/startup, some apps open automatically that are not needed (e.g. maps, Documents To Go, alarm, etc.)
clears up a lot of memory
on Nexus One: not sure yet whether that's really necessary considering more RAM available
I use Advanced Task Manager purely because I bought it on my G1 and so thought I might as well. It has a kill-all widget (you can set exclusions of course) but I don't use that. I normally only use it to kill apps that I want to restart or just to monitor what apps are doing what.
I have tried running the phone without using it at all and using its automation feature to kill everything except widgets and background processes every 30 mins. I honestly didn't notice any battery life difference or performance except that abviously apps were slower to open if they'd been killed rather than when they were in the background.
In my opinion and based on anecdotal experiments, task killers are not necessary on the N1 and certainly nothing like as vital as they were on G1

Bull****. Prove your statement. This isn't Windows we're talking about. Android manages tasks and memory very well, if only people let it... but for some reason people can't understand that Android WILL automatically free memory AS NEEDED. Instead they open a task killer and **GASP** see open programs!! Autostarting certain apps is actually a good thing, since often those are the apps that people tend to use often, so they load very quickly. There is always some free memory with Android, and it never lets it get to a point where that drops to 0.

This.
I thought a task killer was necessary and went out and spent the dollar something on Advanced Task Killer. It made me feel "good" to know what I control what apps are open. But you know what? Ever since a factory reset, I have not put the Task Killer back on my phone and it's been about a week and a half if not more of letting android control my memory... And like uansari said... Android does a very good job of it.
I have not had to close any apps because of short memory. Android does a great job. Save your money.
Android (and Windows for that matter) has great memory management, but it's mostly a problem of rogue apps that don't sleep properly. I have Advanced Task Manager, and I've noticed with the Nexus One I see more "applications" running (like Launcher) that didn't show up on my G1 (running Enom's 1.6 before I got my N1). I found that I had to block a bunch of apps to keep them from being closed, and I got a couple of weird bugs that seemed to stem from closing apps. One of them was this problem with the audio not be routed properly to my BT or wired headset when connected. I use the task manager much more sparingly now, and only kill apps when they act up.
I really wish we had "Cards" like the Pre, so we could always know exactly what was open. Plus, the ability to "alt-tab" (swipe back and forth) is a million times better than this "hold home button" crap. Sigh. Need better alt tabbing.
while i do not disagree that Android does a ok (yes, ok! just that...) job to manage tasks & processes, I disagree that it opens or keeps open apps that are necessary or frequently used. That's not Android that does it, it's the apps that tell it to do it.
for instance (as i mentioned a few posts up), everytime i boot, it opens "Documents To Go"... an app i most infrequently use, almost never, but like to have in case i have to review a doc or excel sheet on the go.
It doesn't have to open on startup, it is not frequently used, but it still opens on start up.
so yes, i do use task killer, on startup. but i use it sparingly thereafter

That's fine... so Document to Go opens at boot, along with other apps. My point is that as you start opening other apps, and Documents to Go stays latent, it will get closed automatically as other apps demand memory. I'm not directing this specifically at you, shmigao... just responding to a concern a lot of people seem to have. Apps automatically opening at startup is common and don't cause a performance decrease.
I have yet to experience any slowdowns on my N1, and I never use the task killer that's built into Astro.
i use "automatic task killer" free from the market and my phone runs fine. I dont even have to think about it, because it clears memory when phone goes to sleep. I think it was more needed on htc magic than nexus.

Exactly.
I stopped using task killers on my N1 because it cause more problems and hosed my battery faster. I haven't used it in almost two weeks, and the phone is smooth and the battery lasts a lot longer.
No need for task killers on the N1, IMO.

HA! Tell me how you really feel....LOL. I have tested my wifes G1 and my old MyTouch and found it gave me about 30% more battery time.
Yes it will auto close programs when it needs the resources, just like a Palm pre, but running processes are just that.....RUNNING.

I am perfectly happy with android managing my open applications and I have no concerns about RAM. My primary problem is that I am given *no* way to actually close an application if I really want to. An open application could still be polling, syncing, or updating and if I don't want that anymore how can I close it without the application developer explicitly coding an option for me to do so?
(an) Automatic task killer gives me the peace of mind that I can close applications that I use only once in a while and start with a clean slate every time I unlock the device.
I am not one of those users who places every single program there and requires a minimum amount of free ram, but I do have it cleaning up programs that have no business staying resident.
Wouldnt it by wise to use the "ignore" list many of these apps have.
That way you can have your frequenly used apps always able to quick load and the ones that you never use killed off.
I understand that Android has good memory management but I dont see the point of having some apps sitting there when I have no intention of opening them up on a regular basis.
Wow! Such heated debate over something so simple!
This isn't Android 1.0 or 1.5 or even 1.6(pretty darn good at auto closing)... this is Android 2.1 on 1ghz w/512mb RAM! The auto scaling of the CPU and the auto task closing is very, very, very good! There is no need for a task manager unless you want to use it to close something very specific because you want it closed NOW!
But there is no NEED for it, especially on the Nexus One. All it will do, if used regularly, is decrease battery life (yes, decrease, because it takes a lot more CPU power to open up an app than it takes to hold that program in the RAM's cache). As well, it will slow down your Android experience... Hero users found this one out, at least smart ones did, that the best way to keep it zipping along was to not use a task killer, except for media rich apps like youtube, music player, video player.
On a G1 running a Hero ROM, slightly different story in terms of speed, it was beneficial for several reasons; 1. Android 1.5 doesn't have nearly as good auto task management as 2.1. 2. A G1 used almost all of it's RAM to boot up the Hero ROM, and thus the auto settings were no where nearly as agressive as they would need to be.
But we are not talking about a G1 running a Hero ROM... we are talking about a Nexus One running stock Android 2.1...
If the OP, or anyone, wants a task killer, get Astro file manager, and use that. Kill the select few apps that you really want to when you get done, but don't bother getting an auto killer that messes with the already amazing job Android 2.1 and the Nexus One do!
it can be useful... i use it to close certain app that autostart or keep running in the background and use the GPS franticly trying to get a location
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.
This is obvioulsy my first android device and although cool. its a lot to get use too. I am used to having a taskmanager to close any open applications or ones running in the background. How do you to that with the Droid X? Everytime i opened an app, i just hit the home button and assume it closed. How do you close a program or an running app? Sorry if its a dumb question
You can download an app manager from the market. However, you probably don't even need to worry about that since the processor can more than likely handle the open apps. The android os is pretty good at managing your apps for you. Some people even say that the app manager messes the phone up.

thank you...i'll just keep it the way it is then and assume the app closes when i exit to the home screen.
Another question for all the Droid X users. Is there a way to remove that little green droid that give you tips on the home screen. He is as annoying as the paperclip dude in microsoft word
nevermind...i just had to drag it down into the waste basket. i did try it before, must just not have draged it far enought donw before
Just to tell you, btw, apps in Android are notified when they get minimized so they can release resources. So say you're in a game, and you hit home, the game knows that you aren't playing anymore, so it's not just sitting on the menu eating resources.

Sorry so are you saying that android automaticaly kills the program when you exit out or say hit home? If so is apps like taskkillers really necessary and why do people have them?
No, task killers aren't necessary, and generally people only have them because they don't know any better. Having loads of free memory will do nothing to increase your performance because most apps don't require much, and the very reason Android keeps them in memory is to reduce loading times. Unused RAM is wasted RAM. Android will automatically kill old tasks if it needs to free up memory, so trying to micromanage and preemptively kill tasks yourself is a waste of time and will only make your experience worse. Poorly designed "automatic" task killers from the Market can even decrease your battery performance, so be wary.
I may fall into the "don't know any better" crowd since this is my first android phone, but I'd had the voice recognition app lock up on me a few times and using the task killer to end the app and restart it was the only way I could get it running again.
Unless you have any way I could have done that, it seems to me that task killer has its uses.
You can kill tasks and services from stock Android's Applications menu under Settings.

Because whoever builds the ROMs for these phones thinks that having built in apps you never use running in the background is a good idea.
DroidX for instance launches a whole bunch of apps on boot you are not using, no need to have them tying up memory.
Even some relaunch themselves in the background when other apps are opened.
So to answer your question, the default ROMs that ship with the phones are generally sloppy. You dont NEED a task killer but it helps speed up the device.
Its like getting a cheap HP or Dell computer from Best Buy, they load it up with some much crap you have to re-image or uninstall all the software you dont need.
You can't unfortunately uninstall the programs that are locked by the ROM.
The only app manager I use is System Panel from the Market. I only used it before on my Eris to monitor memory and battery life. I use it on my X now for informational purposes, because the X is so much faster than the Eris was, which I loved by the way.
Tl;dr its good for monitoring, but above posters are right, mostly unnecessary.

Ok a very general question but why is it so hard to exit an application with android!
This is my first android phone and I love it, I will never use another phone type.
My previous phones where windows mobile and closing an application was pretty simple.
With android it's easier to just turn the phone off each night and back on but I would really like to end an application when I want to.

You need to read up on the subject a lot more.
In a nutshell, Android keeps programs in memory for quick retrieval. If a program goes unused, it eventually gets killed to make room for other executed programs.

as some of the other users have said, android isn't same as windows or iphone ... its based on linux and unlike windows, the memory management is much different in linux
whereas in windows, it is better to have extra free memory and this actually speeds up applications etc, in linux it is the exact opposite ... linux will take care of memory management itself and likes to keep things in memory for longer in case you ever decide to open the same application again.
so in a nutshell, as you're new to android stay away from 'app killer' apps, as your'e doing more harm than good ... it might look nice having 300megs of free memory, but you'll notice a considerable decrease in speed as every time you will doing anything, the OS has to load that app into memory ... whereas if you leave it alone, you will only notice decreased performance once in a blue moon when you open up some ridiculously big app that the linux OS has to remove more than normal amounts of stuff from memory to make room for this obnoxious app ...
anyways, to answer your main question ... this is the main reason why you can't really exit an app ... and that is why multitasking is awesome ...
Thanks for the advice. I have a much better understanding of it now.
I was looking at a task manager app but will avoid them now based on your explanation.
Sorry for the delay in getting back. Couldn't access xda.

what about apps you dont want to use but are always active? like msn messenger or palringo ?
@Psycho
In this case you can use a taskmanager to kill a specific app, not all thing in the memory.
like a do.
I think it's been confirmed, that task killing applications aren't necessary--and infact, use more cpu/battery power; opening and closing an app is far more intensive, than reopening it from memory.
You're best bet is to just leave the phone the way it is, in regards to application/task management. My fascinate did however come stock with a task manager, to force close anything I don't want--I use it rarely.

even in this case, if the app was developed properly you can simply leave them alone. because the app would be running in 'background' mode it wouldn't be using negligible battery if any at all.
however, there is the rare case where the developers will act idiotic and force the app to run in 'foreground' mode even when its in the background, and in that case you can either use a task manager to only kill that specific app or go into the application settings and force close that app manually.
you can, on most occasions, figure out which app was developed with background and foreground running in mind when you check the battery usage. no one app should be higher than 1 or 2 percent over a long period of time, unless its an app that you're actually using exclusively for a long time, such as a game or maps app.
if you see any app that is higher than 5%, either simply get rid of it or use the task manager to kill it whenver you're done with it because thats a pretty good indicator that the developer didn't code it properly and is forcing the OS to keep the app running.
hope that helps

like a do.

I just uninstall such apps. I understand that Titanium Backup can uninstall "system" applications. I just use a shell script. But then, I've been a UNIX junkie for 20 years.
sign out of messenger apps, don't kill them..
Should I Use a Task Killer?
@psycho.. and everybody else:
Check out an app in the market called autostarts. It's not an task killer, it's an task preventer. Once you set it up it just keeps the apps you specify from even running in the first place.
Android does a great job of managing the background but if I don't need an app but maybe once every week or two (gmaps) I'd prefer it didn't even start every time I boot my phone. Another example is that I love the photobucket app, but I don't actually need it to start up every time I take a picture.
I don't kill apps with a task killer, but I still think all apps should have an Exit option.
There are times when you know you're done with an app, don't want the state preserved for next time, and want to make damn sure all its resources are released.
If you want to preserve the state and come back later, back out or hit Home.
If you don't, then use Exit.
Nothing to do with task killers, just a simple app design decision.
I'm seeing maybe 20% of apps have this.
The OS does a pretty good job of deciding which apps should possess which recourses. If an app is particularly hungry for resources and is of the type that is should relinquish those resources when able, the developer should take that into account. A wise developer will know this and develop his or her app accordingly. A foolish developer assumes his or her app is the only app in the universe and doesn't give a damn about the user. In an open environment like the android platform, where the user gets to decide what is best, the wise developer wins.
I have a lot of apps opening up in the background on their own and eating up my memory. Things like qik, skype, city id, vz navigator open on their own even though I barely use them, if at all. My free memory keeps dropping down to around 30mb. Is there anything I can do?

The best remedy I came up with was rooting my phone, and then installing Titanium Backup and Autostarts. Titanium can freeze the apps you never want to use like some of the crapware that comes preinstalled. For the apps that you do use, but don't want automatically opening all the time, you can use Autostarts to choose which conditions must be met for the app to open, or not open in this case. For both of those applications, you need to be rooted, and unfortunately that's the only way I know of to stop some of the apps you mentioned (especially Skype and CityID).
You can root to remove the bloatware, but that's it. Also, memory on android isn't the same as on a PC. With a PC, clear memory means a faster system, but the opposite is true for android. Because of the way it manages applications, you want to keep the memory as full as possible.

This is the answer. There is a difference in night and day with my X since installed Autostarts and Fission.
If you install Autostarts and use Advanced Task Killer you will be able to kill the apps and they won't continue to run/open in the background. It's extremely worth it.

Search android task killers on these forums. Then listen to the posts and let android do its thing.
Task killers bog down the system because these apps are shut down while attempting to do something (sync, send data, etc). The app then realizes that it needs to complete the process and restarts. This continues over and over hogging your cpu resources and slowing down the system.
Stop paying attention to the free memory and open apps. This is not an iPhone.

Except you can put exceptions into what apps to kill.

You're missing the point. Autostarts doesn't allow the app to start in the first place so it doesn't bog down the system or hog resources.
Correct me if I'm wrong but is it not Gingerbread that has added the addition of a task killer.
It's not about the free memory, my phone runs faster. I can tell a difference.
It's possible we may be talking about different things.
I'm pretty sure closing Angry Birds when it's still open because I Home Screen buttoned out of it won't make a big difference.
If you're referring to closing services while they're running, it's a different story. I skimmed through the article, it looks interesting, but I honestly fail to see how closing an app that's running... even one that might be doing something I don't want it to (like using GPS because it didn't close when I back-arrowed out of it).
When I bought my phone, I installed Weather Bug. Weather Bug kept trying to get my GPS location while I was at work. My phone barely made it through work. Anytime I checked the weather, I had to close the program through a task killer, or I'd have no battery because the phone was trying to use my GPS all day.
How does not closing that save my battery?

That's not a valid comparison. The android system manages apps, but it doesn't monitor everything that they're doing to prevent a runaway (like weatherbug). Actually read the article, then comment on it. And you do know you can turn gps off, right?
I happen to like GPS, and as long as I don't have any runaways, it doesn't drain battery since it's not used.
I'm just saying, for programs like that, Task Killers are great.
I'll read it tomorrow most likely.
I tried Watchdog and a few other task killers before finally shelling out the money for the full version of Titanium. I found that often times, the biggest cpu hog and battery killer was the task killer itself since it has to be constantly running in the background. For apps that you use on a regular basis, the best remedy for saving battery life is to just change the update interval period. By default, a lot of widgets (especially weather) update every 15 minutes, which can be a little tasking on system resources at times. I set mine to 1 hour and that helped tremendously. The main reason I went to the full version of Titanium is because it accomplishes what task killers can't by freezing apps to deny their access to open at all. Instead of removing the bloatware like CityID, VZ Navigator, and others, which will keep your phone from receiving OTA updates, just freeze them and you'll never have to worry about them. Autostarts takes care of the rest for me by allowing full control over the condition changes on the device which trigger certain applications to open. For example, I may use Google goggles occassionally, but I don't want it to automatically open in the background just because I enabled GPS. Before rooting my phone, I would normally average between 14 to 18 hours on moderate usage (with a task killer running I might add). Now, with those two applications managing things more meticulously, and chaning the update interval for all of my widgets, I get around 30 to 36 hours easily.
