hi i have only just got the hero and was wondering how to close apps properly. i have noticed that when you hold the home key for a while a window pops up showing some apps ...is this how you close them? or is simply pressing the home key shutting them .
The long press on home just brings up a list of apps that have been recently run. It's almost a task switcher, but not quite!
Many apps will exit if you "back" out of them - i.e. when in the app keep pressing back until you get back to the home screen. However, this isn't the case for all applications. Some may have an explicit exit or close button, whereas others may have nothing at all.
However, Android is pretty good at managing its own applications, and will kill/exit them as necessary. In my experience, there's little to be gained from explicitly killing applications using a task killer, but some people swear by it.
Regards,
Dave

Most Task Killers free up memory thats used by background apps.
so basicly back out of the app and let android do the rest of the worring. thanks for advise

Yes, but the point is that Android itself will start killing applications if it starts to run low on resources. (see http://developer.android.com/guide/topics/fundamentals.html)

I'll attempt to sum it up once and for all, to try and set the record straight.
In Android's virtual machine, there is no functional differentiation between "closing" an app and "switching away from" an app. They are the same (the exception is things like music players which need to keep playing after you switch away from them, but even then only the 'service' part needs to keep running).
Whenever you switch away from an app, its current state is remembered so that even if it is effectively "killed" it can be returned to in just that state next time it's opened. Then Android either kills the process or it keeps it open, killing it when it needs the memory. You won't notice any difference between either scenario, except maybe that an app loads a little bit faster if it was kept in memory. At any rate, "closed" apps do not "run", and they do not take RAM or CPU cycles from other apps.
In terms of process/memory management, Android's VM has more in common with a web browser than a desktop OS - sure it can remember your state when you switch apps (like switching tabs, going back/forward/home in a browser) but whether behind the scenes it loads it all into and out of memory when you switch back and forth, or it all stays in memory is irrelevant to the user. Nobody worries that a long forum page on another tab or in their back button history is occupying 80 megs in the background or not, the browser takes care of loading/unloading it from RAM as needed, and that's just like how Android's VM works when switching between various pages of various apps.
Once you understand this you understand that all these 'task killer' apps are really unnecessary - all they'll do is make it slower to restart an app once closed. They don't reclaim RAM that was previously unavailable to other apps.
To cut a long story short, pressing "home" is a great way to close an app, whether you want to return to it later or not.

that is not true for me, my firefox can eat a lot of resources as long as it is open. and i can see a performance difference when having a lot of apps open on my hero. not that it would be a problem, but you can see the menus scrolling more "fluid" after killing all bg apps, for example.

I would wager that's the placebo effect. It feels faster because you believe it should. If you understand how the OS works you realise that apps you've switched away from do nothing to slow down or take memory from any other app (see my exception above about apps that launch background services such as music player).

I do notice this too. There is a general 'sluggishness' with my Hero when there are lots of app sleeping/running/hibernating/whatever in the background. As soon as I kill off a few unwanted ones, all the menus scroll faster and home screens change quicker.
And this is not the placebo effect either. The menu's DO scroll more fluidly after I have killed a few apps, regardless of how you describe the RAM management...

exactly, you can tell easily if it is one motion or looks like it is "skipping frames". even it is only because it takes the device some cpu cycles to kill other apps, it does make a difference. like i said a rather cosmetic one, since it doesn't really effect the general usage. nevertheless i like to know what is running and what's not, and so far im running good with advanced task manager free.
WOW i didnt expect a massive response for my question but i thank you all for your responses

that's not true, my phone gets so sluggish sometimes that i can't answer a phone call, the phone doesn't register that i press the answer button. and when that happends i usually have like 20 mb of free ram.

Just as a matter of interest, do you use swapper or AppsToSD?
My phone never gets into the situation you've described, but even though I do have the full version of TasKiller, I almost never use it, and I don't see a need at present to use AppsToSD.
In addition, I'd imagine that having a swap partition would cause an issue with Androids own memory management, since I guess it can't distinguish between real and "virtual" memory. So where a "non-swap" device would start killing processes, a "swap" device would just continue on regardless because it thinks it still has physical memory available.

Yesterday I downloaded "Advanced Task Killer Free"... anyone who has experiences with this? Is is better than just "Task Killer" or is it just an updated version of "Task Killer" ?
thanks!
have been using atk free for a while (lol 2 weeks since i got the hero) now, i really like it. its advantage over all other task managers IMHO: it has an ignore list, things you ignore are not shown in the running tasks list. in the list you have check boxes, where you can select the tasks that will be killed, and this list is remembered. for example "htc sense" is on my ignore list, but "music" is only checked, so i can uncheck it when i don't want to kill it while listening to music. next time i want to kill music i just have to tap the checkbox, no dealing with the ignore list here...

I get this problem a lot, and in answer to fox meister, I don't have AppsToSD.
I don't know if the problem is RAM or CPU related, but the CPU often jumps to 100% when things are really slow.
Is the issue likely to be background apps, or widgets even?

Same for me with the processor.
When i reboot my phone i usually have 90 mb of free ram, after starting a few applications, like browser and phonebook, it plummets down to 20 mb.
I do have some extra applications that starts as services, like systray monitor and 3g watchdog.
when i open atk after a fresh reboot i see that some applications that i don't even use is started, like footprints, settings and calendar, even my webrowser is started, whats up with that, can it be disabled?
I think the issue is that we have some applications that autostart withous us using them, and also programs that we download that autostarts as services and maybe having memory leaks...
I came to chime in with my experiences of the CDMA hero and sluggishness.
I watch memory like a hawk (thanks Mogul) and I too have around 80-90mb free ram on start, but it can get down to around 30 rather quickly. Once it gets down here, I notice that screen transitions and random lag occurs in apps. If I go into Advanced Task Killer and kill many of the stragglers, my menus are as smooth as can be.
It is most certainly NOT a placebo effect.
One thing I really like about Advanced Task Killer (pay version) is that it has the "Auto End" feature, where it will kill all apps not chosen to be excluded at the interval that you choose. For example, I have determined the system applications that need to be on all the time, and I've excluded those. Every hour, ATK kills everything else. For the most part, my Hero hovers around 70MB now at all times, although it can get down there to around 30-40MB if I'm right around the 1 hour mark.
That feature alone makes it much better than Taskiller IMO. Totally worth 99 cents
This definition would imply that android works exactly like the iphone osx? I mean saving "screenshots" of the last state of an app. But NOT having real multitasking?
Because it's not possible to have multitasking and at the same time "inactive" background apps everytime you hit the home button...

No, you've not understood the explanation.
The iPhone will always* terminate an application that isn't on its list of "approved" multi-tasking apps once it isn't active any more (i.e. you've switched tasks).
Android will try to keep whatever it can in memory, but eventually will start killing processes in order to keep the system running.
So, if you're on an iPhone listening to something on Spotify and you want to browse something on the web, the iPhone will "kill" Spotify when you switch to the web browser. On Android this won't occur except in the most critical of resource low situations, but then again, I'd imagine other apps would get killed before Spotify.
Read this article, specifically the section from "Component Lifecycles" onwards specifically "Activity Lifecycle", "Saving activity state" and "Processes and lifecycles".

Dave

hi all, im an owner of a sam.charge. I use the app called "System" and it lists about a dozen apps that are stored in my cache or that are using memory when I have not innitiaited the service or app...
I'm most familiar with computers so I'll relate it to that; is there some type of command line that I can use to stop some of these apps from auto start and being stored. For instance on windows you can 'msconfig' what programs are allowed to start on boot up.
Here is a list of apps that I want to stop: AccuWeather.com, Android Booster, Google Voice, HeyTell, Amazon's Appstore, Market, Music, etc.
Most are cached/ inactive but none the less in my task manager when freeing up memory when I notice things to be lagging I'd imagine these to be guilty. Android Booster always lists these as killed apps as well when optimizing...
Im familiar somewhat with how android works being that it often fills a large portion of your memory with what it wants to and frees space as it is needed but these apps for me are rarely used...
Im big on battery life being Im in and out of Sales accounts and rely on my phone heavily so I dont want these things running in the background sucking up resources. Not to mention I like a snappy phone...
If anyone could educate me on this topic Id really appreciate it... I may be mistaken on a few things so call me out on it, since im sure I am... Also, I know their are app freezers and applications you can program to kill apps at a set interval but again I would like the least amount of garbage running as I can

Some of the basic services are must to be initiated/running all the time such as launcher, keyboard, google voice, market, etc.. so as to run your phone smoothly . This is the default setting of android os. And anyway why do you want to close/stop the services case restarting services uses more battery than kepping them running on the memory ....

If you find apps that you don't use, you can use a program to freeze them. Just search for freeze in the market. I personally use a free app called System Tuner. Freezing prevent them from starting up and therefore you cannot use them, but later on you can un-freeze them if you need to.
Optimize toolbox
I use this one, had a bunch of other features.https://market.android.com/details?id=cn.opda.a.phonoalbumshoushou&feature=search_result
Thanks all for the feedback...
To reply to the first response; I have read that about battery life. That, the more you kill apps and reopen them that it takes longer for the app to start up and thus sucking up battery life... I probably should not have mentioned battery life in my post being that I have a car charger and that it contradicts what im trying to accomplish (going over my post, it was stupid of me given what you just mentioned). Also, I'm not so much concerned with market apps or google voice as I am about the apps I installed myself. Those ones are the ones that bother me.
To the other posts thanks for the recommendations I will like into those options. I'm just trying to prevent extra apps from running in the background so freezing them is a last resort.
I'm looking for something that I can type in terminal possibly on program into the OS or app itself to keep it from auto starting... possibly a command line?!
Any developers input? Can this even be done. I'm still very much a beginner but its not beyond my comprehension to do something like this... I know its different but I play around with linux, web design, c++ stuff so if you post directions I can follow smoothly our atleast figure it out if you point me in the right direction

It's not exactly what your asking for but have you tried Gemini App Manager:
https://market.android.com/details?id=com.seasmind.android.gmappmgr
You can use it to disable/re-enable an app's autorun settings. When you first open it it will list all user apps currently in memory. Clicking menu then expert mode will give you a list of all apps. Long press an app then click configure autorun.
Just be careful with changing the autorun settings of system apps like market.
"preventing apps from autostarting"
I like this topic a lot!
I think the question(s) and "assumptions" the OP holds are all valid. So I'd really like to hear the answer to the actual question, not a spew of why the question isn't valid.
How do you stop apps from starting up on their own? (like microsofts msconfig)
Pretty simple question and I cannot find the answer! I've been in software for many year and I'm rather stunned by the responses people are giving - which basically say "who cares, android O/S handles it for you".
Well, lets face it:
*If* the user didn't call for the app, and had no desire to use it, then the "system" loading it even ONCE, is one too many.
*If* the app is a DESIRED app, (OR device required), *BUT* uses data - then if the user didn't want to use it; "yet" - then thats DATA & BATTERY life --> **WASTED**
If the user suspects the APP is misbehaving; one sure fire way would be to SEE it running, when they didn't ask it to!
If you are pure paranoid, or simply want extreme app control....
The kinds of answers people are giving is truly along the the lines of "we dont know, but you're silly for caring"
SOYLENT GREEN!!!!!!!!!!!!!!!!!!!

Hello!
I installed ES task manager today on my new Nexus 7 and I was shocked to see that several apps are consuming 20mb+ of RAM when I don't even have them open, such as Titanium Backup, Facebook Messenger, PIE Controls, Auto Hide Softkeys. Even apps like YouTube, Gallery, Chrome, Currents and Hangouts seem to be running and using RAM and I have never opened any of these applications before. The actual app switcher shows that I have no apps open, yet ES Task Manager reports that 25% of my CPU is being used. All in all, an almost fresh install of Android idling is consuming 1GB of ram and 1/4th of my CPU time.
I have Googled this issue and discovered that many people are annoyed at developers who have background services, and sometimes even refuse to use an app that has such background services, but I haven't been able to discover why these background services use so much RAM (or even why titanium needs a background service), and I would really like to be able to just kill Chrome, Youtube, Currents etc because I never use these, but of course when I kill them in ES Task Manager they re-open within several minutes.
Can anybody shed some light on what's going on here? From what I can gather after searching around the forums, some people advocate the use of task killers, and some people also say killing all these services and apps just makes battery life even worse.
Edit: google+ is using 20mb of ram and I never even use it-- why!
If you are rooted you can use apps like Greenify to pause them temporarily until you run them. You can also use apps like Clean Master that will kill all task on every screen off. Ultimately you can remove these apps that are taking up a lot of ram as the best solution.

Wow, didn't know something like greenify existed, thank you!
I understand the whole approach Android uses to memory management as opposed to Windows etc....
I also found this blurb below
It's important to note that Greenify is not a task killer (which you shouldn't use anyway), and it doesn't "freeze" apps. The apps that Greenify hibernates are still usable if you want to switch to them, and you can still pass data to them as though they were running. When you switch back to them, it's like you never left. Greenify just keeps those apps from launching new background processes (a problem with task killers) and you don't have to unfreeze or thaw an app to use it when you want to (a problem with "frozen apps").

But here is what I don't understand:
1) Even though it isn't a Task Killer per-say, it sure sounds like an advanced task killer to me. If it is preventing something from starting up, it is killing it.
2) What benefit is Greenify supposed to have? Having all (by all I mean maybe 5 at most) desired apps hibernating, I have 700MB of free memory (using xposed method). If I remove Greenify I have 1.5GB of free RAM. These numbers are with ALL applications already open since boot that I use on a daily basis.
While full memory is not a bad thing in Android, how can it be better having 1 app hog all of the memory vs having 5 apps running in the background using less memory. Can someone shed some further light on this?

Sounds completely weird.
the main benefit of greenify is the point that it prevents apps from starting (they are frozen untill you open them) this way the apps can't force wakelocks and your device kann stay in deepsleep state longer

As I understand, greenify to me is more to battery saver depends on stopping unwanted and unneeded wakelock when app is Greenified. Also as I understand, when an apps launch or relaunched, it will consume more ram in normal way (without being Greenified).
Try this, its not a solution, more to suggestion. Try use Wake Lock Detector along with Greenify, one app will detect the problem and another will execute an action to prevent "unwanted battery and RAM usage".
Above all, it depends on how and what method of modding you perform on your device.
Its just my logic thought(not black n white proven). Hope it will help us a little.

Well - not my experience; defaults work well on most devices. There are brief in-app explainations for many options with expanded material in FAQs, XDA forum and G+ pages. Best consider an iDevice if you need/want handholding; genius bars everywhere.
