Close apps properly?

I was messing trying to figure out which is the correct method to close apps, back and home do the same thing, holding HOME (i just found out) brings up a list of recently used apps, but i can't figure a way to properly close them. I have Advanced Task Manager to close them now and again but I don't want to keep it running all the time.
Is there any proper way if the app doesn't provide an exit function?

Because an app is on that list does not mean it is not closed. That list is just the history of the last 6 apps you used.
A lot of people say that you do not need to worry about whether or not an app is fully closed because the software manages that to ensure that it has enough free memory. I don't know enough to know whether that is correct or not.

Yes, sorry, the apps I'm referring to are shown by the Advanced Task Manager, I merely found the Recent list when trying to find a way to exit apps.
I sometimes have 15-20 apps in there filling up my RAM even on startup things like Shop Savy will be there twice and Photoshop.com.
They, amongst others don't seem to provide options to prevent them starting at boot so I simply uninstalled them, but all the running apps do severely affect the performance when it's filling up.

I have been experiencing the same problem.
Advanced Task Manager lists a whole load of apps that start on bootup and each one of those doesn't have an option to disable this.
After a while (about 3 hrs or so) of using my Hero I am down to about 40mb of RAM which if I don't use Advanced Task Manager to kill unused apps my Hero begins to lag big time.

On the Android it is better to leave them resident in memory than stop them, unless they are 'background' processes and there is something wrong with them (a bug) making them slow down your phone.
Don't judge your Android on amount of free memory left; if anything, the the less memory left over the better as it means the memory is being used effectively to make it nice and speedy.
Processes aren't allowed to consume CPU cycles/consume battery/slow your phone down when they are not focused; the exception is background processes which need to keep going, like the music player etc. What's more, if an app is not focused then its state is preserved allowing your phone to free up its memory when needed; its memory effectively becomes 'cache' allowing it to restart quicker if it happens to have stayed in memory.
So don't worry about wiping an app from memory; for many apps there is simply no distinction between closing it and switching away from it; as soon as you switch away from it it's as good as closed; it's not slowing your phone down or taking up any memory that couldn't be freed instantly if needed, but if it is lucky enough to stay in memory it will re-open quicker.

On my experience, if you press the back button to exit an app, then the app is closed properly, running the code in the app that will release the memory and objects. This is the best way.
The only app it will not work on is the browser as the back button will send you back through the history.

I understand how and why this should be true, but for me it doesn't seem to be, if my memory falls to less than 40 the phone becomes increadibly unresponsive, I get crashes and have to wait forever for it to do things like open the phone. Immediately after killing all with advanced task manager it goes back to normal.

I have tried both methods, more often than not though, back doesn't seem to do much either, I have experimented with free RAM and using back or Home, it seems the Home certainly isn't the correct way to do it, but back doesn't work very often either, maybe people aren't coding their apps properly to respond to the back button as an exit method?

this is the never ending discussion whether task manager make sense for android or not.
i'm one of those who say: definetly YES! USE TASKMANGER.
I understand that Android works in a way that taskmanager shouldnt be needed because it handles the tasks on its own, but sadly the concept just doesn't seem to work.
When my ram fills up i can cleary see that the device is getting slower, even just opening apps takes more than 5 seconds. After closing some apps the hero is fast again.
now i don't care whether ANDROID is the reason or some POORLY programmed background apps, because the outcome for me as a user is the same. I#m using advanced task manager and im very happy with it, whenever Android starts to slow down i close the open and unneeded apps, and everything is fast again...don't know how people can claim that Android does handle task management perfectly on its own.

The point is, Task manager of any kind is another 3rd party app taking up more memory, and quite frankly on such a high end phone i shouldn't have to worry about this problem. I noticed another thread about changing the values at which the internal task manager kills apps etc, if it becomes more of a problem i'll look into this method of fixing it.

yes, in theory we shouldn't worry about tasks in the background, but in reality as you said, the device WILL slow down. so there is no other way around than closing apps manually and defining apps to be kept alive by the 3rd party task manager.
changing values for the internal task manager sounds like something which would only work on a rooted device, but im not sure...

Why are so many programs starting on their own?

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.

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.

Apps keep opening in background

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.

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.

[Q] step by step instructions to delete All unnecessary files from rooted play

OK so my built in memory is always too loo and I'm really getting sick of it. could someone please tell me, with step by step instructions, which files I can remove from my play without crashing the phone. I know that's asking slot but it would greatly appreciate it. thanks in advance.

step 0, open the "safe list" thread at the top of this forum
step 1, download Titanium Backup
step 2, within the app, tap on which App you want to delete
step 3, tap on delete app
step 4, what model phone are you asking about?

Infact it's the oposite, people say you should use task killers as it interfears with androids native memory management, Android is a linux based os and thus "pools" memory, so although the memory may appear to be used, infact it's not, it is pooled waiting to be used by the os, this gives much quicker random access.
http://lifehacker.com/5650894/andro...ed-what-they-do-and-why-you-shouldnt-use-them
"In Android, processes and Applications are two different things. An app can stay "running" in the background without any processes eating up your phone's resources. Android keeps the app in its memory so it launches more quickly and returns to its prior state. When your phone runs out of memory, Android will automatically start killing tasks on its own, starting with ones that you haven't used in awhile.
The problem is that Android uses RAM differently than, say, Windows. On Android, having your RAM nearly full is a good thing. It means that when you relaunch an app you've previously opened, the app launches quickly and returns to its previous state. So while Android actually uses RAM efficiently, most users see that their RAM is full and assume that's what's slowing down their phone. In reality, your CPU—which is only used by apps that are actually active—is almost always the bottleneck."

really, thanks for letting me know. but I do notice when I use advanced task killer games run smoother, though I find five minutes after I closed an app it automaticaly reopens.

there a lot more things showing up in titanium backup, anymore suggestions? Rogers xperia play Canada. my phone is starting up alot faster.

when I try to uninstall certain things it just hangs and says uninstalling but it never finishes. this happened with gmail and liveware manager.

No trouble just know that android has a memory threshold, it will let processes run until it reaches that threshold, then it will start killing background processes, you can remove/stop all the processes you want, but another app will just take over as the os wont stop it, the only way in reality to have more free ram is have no apps anyway you should search for an application called "mini free manager" this lets you edit the values of the native memory manager, you can set it to be more agressive, android will allow less background processes to run and thus free up more ram

I was bored so i went and found it for you
http://forum.xda-developers.com/showthread.php?t=630262
give it a try before you gut your phone trust me

are you sure it's mini free manager and not mini task manager, cause I can't find mini free manager anywhere.

how do you use task killer? like, to set it up? I heard it can put your phone into an automatic restart loop if you don't know what your doing.

U can go into ur text messaging settings and lower the amount of text messages thats phone keeps in thread to like 50 or less. That help me before I rooted to free up memory and stop phone from locking up

Enable usb debugging under applications development settings before starting titanium backup app - this definitely solves hanging when freezing apps so suspect same for uninstalling
