About Android multitasking.. - Android Q&A, Help & Troubleshooting

Hello
First of all, Sorry for my bad english
I am using Galaxy S Plus i9001 (has 1.4 ghz proceesor and 512 mb ram)
and i wonder why Android cant multitask ?
If someone calls me while downloading some files from internet, Opera is killed and opening from beginning.. And my downloads are being corrupted..
Same for messaging too..
Its really annoying even Symbian could multitask with 680 mhz + 256 mb ram on my c6-01...
Thanks.

Strange isn't it? My old Omnia with WM6.1 was better at multitasking than Android!

Its not android blame...
The problem is in the application, on this case Opera.

nah, had it happen to me also, almost all the time.
It does this with almost every application, except those that elevate their priority themselves (i.e Titanium Backup, Better Terminal Emulator, and somehow the Android Market as well -ever noticed how the auto-updates go on even though you've started 3 or 4 other apps in the meantime ?).
The problem lies more in the way Android is configured by default for RAM-management. Using a memory optimizer like the V6 supercharger helps a lot, just use the "multitasking" setting, and it'll be much better you'll see
And if you're still not happy, just use the "bulletproof" script on the app you want to stay open, it'll be almost unkillable by the process manager then..

Sorry to restart very old thread, but this concerns me a lot.

I did not understand what is V6 supercharger, and I didnt understand "bulletproof" script either
Second of all in no way Android has "true multitasking", true multitasking is about giving control to users as to which apps he wants to stay open and which to be closed. Android however prefers to close my browser app(may be because it has holds more memory), and keeps apps running such as facebook which I don't use neither do I intend to use any day,
however its the closure of running app bothers me a lot, specially as it causes browsers to reload data.
There is android blog on "Multitasking the Android Way" by Dianne Hackborn.
If you read that blog it mentions how multitasking occurs on android, it brutally kills app when it needs memory, and the reasons they have posted are rather correct,
But this poses another question, symbian S60 had true multitasking, I ran more than 15 apps on my most basic symbian device and it took all that without sweat.
How did symbian handle this memory issue??

probably because symbian os doesnt eat ram as much as our stock rom? aosp roms like cm and miui give me superb multitasking..

[Q] Task Manager/Killer Apps - Good or Bad after 2.1 update for X10?

Hi All,
I came across a few articles online that suggest that the task managers/killers actually do more harm than good. As far as I know, the Android OS is pretty good at multitasking and managing apps when it is needed to free RAM/CPU.
Would like to hear input specifically regarding the X10 and how these apps affect the system and/or phone specially after the 2.1 update?
Thanks!
Well aince I got to 2.1 Ive havent found the need to download a task killer. Its been stable with 100-140mb constant no matter how many apps I open. But in 1.6 I was getting 20mb if I didnt use task killer lol im guessing the need for task killer as the os upgrades gets less and less as 2.2 really gets ****ed by it lol

I've read online about how closing some apps such as mediascape will affect your other media applications cos these services are tied together. But I've always killed all of the ones I don't see myself needing in the next hour or so, and nothing's ever really crashed for me heh.
But I do make it a point to close all apps before running quadrant. Very very pleased with my 730 score

Dumb question, how do you check the RAM?
Best get something like autokiller memory optimizer.
You generally don't need much ram free and if you don't use apps that will eat the hell out of your system in the bg then there's no problem at all.
I haven't used a task killer since switching to 2.1 and there's no performance problems.
I still facing ram problem even after upgrade 2.1, hope no need any task killer anymore once we get 2.2

Not sure if the X10 will get 2.2. Looks like 2.1 is the end of the road for us.
By automatism, after I updated to 2.1 I installed advanced task killer, and at one point I noticed that, whean I had killed apps ammount of free RAM decereased ? So at that point, I uninstalled task killer to check will I notice any change in performance, and there was NONE I could notice, together with same battery duration.
So, so far I vote for no task killers.

Yeah I know we have custom ROMs. I was referring to the official update from SE. I know we will get the UXP update sometime in the future but, not sure if they will go as far as releasing a 2.2 update for the X10?
I don't use it anymore since on 2.1, when using it on 2.1 there's a lot of glitches and it DOES do more harm than good. I get better overall performance without it.
I use it, facebook, skype start by themselves and drain my battery

Yes but, according to Android developers, 2.1 automatically closes these idle programs to prevent that. They claim that android is capable of handling this and that any task manger apps are useless.
Read this article http://androinica.com/2010/05/07/go...-imply-task-killermanager-apps-are-pointless/
Since upgrade to 2.1, I installed Task Killer. It cleaned my memory to have available mem from 80MB to 150MB. However, it got some weired behaviour such as
- X10 got lag for a moment when the screen is just back on.
- when the screen is just back on, Wifi cannot reconnect. I have to disable and enable it again.
So I read to post of Android multitasking and I try it by disable AutoKill but keep the widget on the sceen to see the available mem.
My mem keep available around 70-80MB and X10 performance is increase. No more lag or have to re-enable wifi after screen is back on.
I already remove Taskkiller but installed Watchdog instead. Because there are some bad coding software out there which comsume the battery and CPU even you've exited. In such a case, I have to kill those apps manually.
------------------------------------
X10i Generic Android 2.1, rooted, JIT enable.
You want the memory to be as full as possible!!! This means that those often used tasks are there, waiting. This is not Windows! Stop forcing Android to reload everything from scratch! No wonder things are lagging for you.
I've done many experiment about it.
Here's few conclusion, everything you guys claims are all true.
Android is nix base, fulfilling ram mean more cache, more speed.
However, more process mean more CPU usage in some service.
Some softwares are not properly coded, it, unfortunately, doesn't release the resource when it exits
And it's also true that force killing it, will eat more battery because without properly closing, it will eventually open up again
I suggest, instead of killing a task using ATK.
try this one.
http://andrs.w3pla.net/autokiller
It teaches android how to deal with the memory, so it's android who do your dirty job.
Hmm.... I take a look at at autokiller. I think it's better to let Android handle the mem for me. What I'm looking for is an apps that monitor backgound processes/apps that consumes CPU and memory which they should not.
Once identify those apps, I need to kill them individually.
Watchdog paid version suits me well on this purpose. I can put those apps in the blacklist. If they consumes more CPU in the background process, Watchdog will kill them automatically.
I may consider autokiller when I have of low memory warning from my X10 which is currently I have not.

I do without but my phone is seriously laggy at times, it drops under 20mb free ram within seconds after rebooting, extremely annoying! I heard things about jit, but I really have no idea how it works. Also I have a mac, so all those adb needed programs I can't run.
Is there any good application which can make my phone quicker? Now I have some times half screens by sliding through pages in the launcher, that can't be normal!

Try install these app
1. RamDroid
2. Advance Task Killer- set the killing frequency to 'switch screen off'
3. CpuTuner (setcpu)- i prefer use the 'ondemand' frequency cos i wan to conserve battery.
all free app.. and need rooted phones. it quite user friendly. jus play with it awhile, u'll know how to use.

I'm using minfreemanager from market with aggressive option, what gives me ~70MB free RAM by the Android's native taskkiller. It's the best choice as of the 2.1 have a lot services running in backround and nobody should harm them.
Trust me, minfreemanager is your weapon against slowness

[Q] Task Killer?

I've noticed that on my Nokia Lumia 800, you can not exit programs or close them down, its seems i can only press back or the windows button.
Are these now running in the background and causing my battery to suffer?
If so are there any sort of task killers or enders.
Also 2 other issues i've noticed are that when i ring people my phone just goes black and does not give me a key pad any sort of button to end the call.
Also when i play my music, it does not have a stop button just a pause, and when i exit it just starts playing from paused. Only time i can get it to stop is when i turn my phone off/on.
Any feedback will help greatly.
WP7 has no real multitasking. So even if an app is "open" in the background it is paused and won't do anyting. Except spotify and the music app that can run in the background.
Task killers is an evil thing on Android and so would be on windows phones. They are not needed as the system handles these things better themselves.
If the screen is black after a call, press power button and it will light up. This is a bit buggy, to end calls at times. Usually I just wait till the other person ends the call so it quits automatically.
This isn't android. There's no need to worry about apps once you exit them, or worry about the music player. If it isn't playing then it isn't doing anything.
That's one of the joys of iOS and WP7. You do what you need to do and never have to worry about what the phone is doing. What's the point of a phone where you need to constantly worry about task killing?

So true. I hated that about Android. Most tasks that kept starting were things I never wanted to use. Had to use Titanium Backup to freeze them. What a pain.

There is a backup for windows phone. It's in the WP7 section of this forum. I've used it before. It backs up the entire phone. (i'd have to search for it)

Coming from 2.3.5 and 2.3.7 I can say that a task killer was necessary. Processes opened up and did whatever they wanted whenever. I had to freeze a few things in Titanium Backup and then set a whole bunch others to autokill. It's annoying that apps can up and do whatever they want whenever they want on the Android OS.

That's just not true. The resource management on Android is problematic. The problem isn't that apps I'm using and switching between are still using resources in the background. If I opened an app and I expect it to still do something, that's fine. The problem is that after an hour or two, if you check any task manager, a ton of apps are listed as running.
You can say these apps aren't really running all the time and are frozen, but they were running at some point without me starting them. These apps do take resources, drain battery and make the phone's performance crap. Everytime I would kill those tasks, the phone would be snappy again. Setting a task killer to automatically kill these apps once an hour, increases battery life.
on ios and windows phone, only one app is really running and the others are suspended. There are a few exceptions (like music players)
on windows phone, you can completely control which apps are allowed to work in the background and start on their own and the OS controls when these apps can run to perform some operation and devs are very limited in what they can do. so apps don't start on their own without the user being able to control that and apps don't stay running in the background forever without the user ever knowing about it

I'm sorry, but if you actually use an app that uses AirPush ads, it's your fault.
Never ever support developers that use this useless piece of crap ad service.
I happen to know a thing or two about mobile development (not only Android but also iOS and WP7) and they are all designed to not have to care about task killers.
Also, if someone really has to bash an OS because of problem X or Y, take a look at how the system works and realize that everything is perfect (for example, Android keeps the VM running to make the app start up faster, but as long as no code has to run through, the VM is just sitting there. Why have all the RAM if you're not using it?)
Please guys, start to read things up if you have no clue. Nobody should have to care about task killers at all and that's what ALL of our current mobile OS's are designed for. Start to develop apps for every single OS if you really want to brag about restrictions and design problems.

Ok, this is great and all that no one should have to think about task killers, but the obvious truth is that Android allows things to run whenever they damn well want to.
For example: Google Books likes to run in the background. Why? I don't use it. I don't want it. Yet, it still does what it wants to.

The virtual machine is just sitting there, doing nothing. It helps speed up restarting the app in case it has been wiped off the memory. The VM still is in RAM, but no execution is happening as long as you start the app up again. Also, it might be itting in the background, doing nothing, waiting for the Google services to trigger a sync, in case a new book has been added to your library. If you have sync disabled in your account settings then it's just sitting there doing absolutely nothing and will finally be just wiped off the memory itself in case an app needs the resources.
With task killers, you kill a lot of apps that are flagged as "Don't kill me, I'll reapper as soon as possible", causing more trouble because the whole VM process has to be restarted, the app has to be reinitiated, code has to be reexecuted etc. That's the perfect way of working against how an operating system works.
To add a point,
it's important to note that there are 2 different things being discussed here:
1) Cached tasks that are suppose to not cause any lag, but do. We know this because we see immediate lag fixes after killing cached tasks but not services.
2) Services that are unnecessary, such as Google Books and Fring.
I think there's a reason why Apple chooses to disallow multitasking even if it's a quintessential as playing a tune while browsing on the iPad in 2012 - it may be a crude solution but it's simple.
Personally I'm tied to a battery hog app due to social means, so I'm looking for an automated service killer for Fring.
There is also the 3rd accusation
3) that the service 'Android OS' in ICS 4.0.3 causes drain in some circumstances for some people who have installed apps but also ruled out (1) & (2)... possibly wake lock related even though there should be no wake locks.
People rarely disagree on things enough to argue unless they're actually talking about different things without noticing. So be sure to clarify which of these 3 wakelock related things you are talking about to keep everyone sweet.
The best of course is to blank everything and start again for testing but failing that use a wake lock measuring app. Can anyone recommend one for me?

[Q] True multitasking?

Is it possible to make Android NEVER automatically kills running apps, to have true multitasking like on Maemo and webOS?
I am really sick of it killing apps that I use.
I tried V6 supercharger, but that didn't help... I looked everywhere for an answer, but I never found one.
Surely there is a way to make Android multitask like a proper PC, where it's the user who manages apps?
(And please don't tell me that I should leave it to Android, that it knows better, and etc.)
Now, before you start defending Android:
Ever had your browser refresh the page by itself after switching to it?
Ever lost something you were writing when you switched to another app?
Ever had a video pause because you switched from the player?
That shows that Android does NOT have true multitasking.
Now, I see why Google did that - battery life. However there is a new class of devices, where battery life is not such a problem. Tablets.
And yet they still suffer from same issues.
Now, here's an example: the browser. Very often I'd come back to my browser, only to find that it is reloading the page I was on, wasting traffic, and losing whatever text I typed.
That's stupid, right?
I can even track back to what device did this first - the iPhone.
iPhone 1 had 8 times less RAM than your average high end device, yet they still have a similar problem.
So yeah. Not true multitasking. Even in the app switcher, notice that it never says "running apps", only "recent apps" - because it isn't a true multitasking app switcher, just a history of all recent apps you launched.
Go on, scroll to the very top, launch the oldest app on the list. I'm 99% sure that it has restarted. This would've never happened if Android had TRUE multitasking.
Now, there has to be a way to get that. Desktop Linux does it, so Android probably can too.
If you ever notice that the app restarts, it's the app that is badly implemented. All apps must be able to handle a restart by Android transparently to the user by saving its state. If not, tell the app developer to fix it.
Chrome, Dolphin, Boat, Maxthon, AOSP, ICS Browser+, Opera, Firefox.
That's a list of browsers that have this problem.
Do you really think that they all implemented multitasking wrong?
Again, it's a problem with Android - I don't want apps to save their state so that Android can kill them - I want them to never leave RAM at all.

Maybe dont answer all ur questions:
http://stackoverflow.com/questions/...lication-is-that-frowned-upon/2034238#2034238
Apps who properly implement onSaveInstanceState() can come back, in case of web browsers is more complex to use it properly, texts or images are simple to imagine how to OS save on "disk" to retrieve later, what about sockets or open files (can be deleted while in background).
Android keep on background until the resources are needed for another task (and maybe a time limit, but dunno for sure), if happen very often w/ u means ur OS r using more resources than what need to keep on background.
Android has true multitasking, but... eh here's a link. Read yourself.

But is it possible to make it so that apps do not get killed at all, just like in Maemo or a normal PC?
What you showed me is exactly why Android does not have true multitasking: it uses stuff like services to actually have less things running - and I don't want that. I want all apps to truly stay in the background - so a YouTube video would continue playing, just like when I minimize the browser on my PC, and etc.
I understand why that isn't the default behavior on phones, but it could be really useful on a tablet.
I don't want to be at mercy of app developers - since even Google messes up: every time I switch out of Google Talk, I lose what I was typing.
I'd much rather have a limited amount of apps that I can launch at a time, and be able to manage what I want to keep open myself.
What you are asking for is basically to completely change core Android behavior.
Sorry, but its just not possible

It is possible, because it's been done. There was a guy who did it over on the V6 supercharger thread, but I don't think the how he did it was ever released. Instead it was developed into a "kill apps only when ram is REALLY needed" method, which could run up to 20 apps at a time on some phones apparently

I get what you are talking about but I'd say is what device your using. My eVo 4g lte's was written screwed up by HTC. Maybe yours is like that too. My rom maker and other devs have done many fixes for it. It has got better but my eVo and eVo 3d still multitask better, and it is true multitasking. It doesn't work like I'm talking about on all devices, but for u to say it's all of Android.......... It's not.
Swyped from my eVo
The mulittasking in Android has some limits which are quite annoying. On my Droid 3 apps that I haven't used will start in the background and waste RAM so there isn't enough RAM to multitask and the device is laggy. I tried rooting and freezing bloatware, but other apps have just filled the void by automatically running in the background. I really wish the user had more control over multitasking. Unless I open an app I don't want it to start in the background, even if there is enough free RAM. But Motorola makes some pretty bad software so this could be the issue.
On my Touchpad with CM9 multitasking is quite a bit better. Not sure if its having 1GB of RAM, improvements in ICS, or just CM but you can actually run several programs at once without them closing, so my browser pages stay loaded.

Did you patch services.jar with the multitasking mods?
Yes, with "Jelly ISCream Automatic Patcher".
V6 script showed me that I'm 100% supercharged.
well...I didn't experienced these kind of problem before. android indeed has good multitasking stuff. the number of app running on background depend on the ram size. you can't expect to run such heavy app with huge ram consumption on such device with low ram. anyway, you can try to play with minfree stuff. try to minimilize the value
The Note 10.1 can have side by side applications, is this what you kinda mean?

Well the latest one is actually called Ultimate Jar Power Tools so if you ran that, and enable Maximum Multitasking Mods, then you should be getting better multitasking/app reloads.
The windows exe would do the same thing of course and is up to date.... well until I update it later cause I'm adding the Sense 4 mod.
Any idea about how many apps you can run before vs after?

Galaxy S3-Hopeless multitasking?

I did use the search function. There was a similar thread posted a day ago but I'd like to do a more in-depth query here. The more extensive one has been dormant since April so I figure that I might as well open a new one.
I'm sorry if this sounds like a rant, but I want to do a serious investigation of the multitasking woes in the S3.
Just some background of my experiences:
Having flashed the latest official (ending with MF6), I must say that multitasking is just atrocious and my apps close for every 3rd one I open. RAM is always full, and once cleared it is bogged down again. And again. And again. The iPhone 4, with 512 MB RAM, can manage better than this. The RAM heavy ones (Facebook, Chrome, YT, etc.) are the worst of all-as they close down even when you don't touch the phone for a period of time.
What exactly is using up my RAM? Please don't come back to me with the Free RAM=Wasted RAM argument. I have seen no speed improvement of apps "cached in memory" compared to those that I just opened up.
I remembered back in the days of the S2 release people called 1 GB RAM unnecessary, and to an extent this is true, as the S2 was able to do some serious multitasking of 8-9+ apps without having to close any of them. Other flagships (HTC Sensation) did fine with 768 MB RAM. Heck, the Galaxy S1 seemed fine with 512 MB RAM. The OS can run, camera works fine, I can play videos fine. So where exactly did this 512 MB of extra RAM go, when the Galaxy S3 is upped to 1 GB of RAM?
I have tried zRAM 300 MB, 400 MB, 600 MB. They all make the phone remarkably slow. Initially it does prove to be somewhat useful, but over time multitasking becomes completely hopeless again.
Is there ever going to be a solution to this, or do I really have to get a 2 GB RAM phone to actually be able to use it?
Well, mate, this has been discussed over and over as you may be aware. Honestly, i've lost hope for stock firmwares on multitasking. Some people swear by zram or even swap and while it does work i didn't find the results very good. Someone may come up with a more thorough explanation on how all the ram is being actually used (and it has been written already, i've seen it around) but at this point i just don't really care much.
Bottomline, you have 3 options:
- install some aosp rom and never see this problem again (some others may come up due to lack of sources for exynos)
- compromising speed for multitasking purposes with zram, swap and there were some atempts at plain better multitask management with supercharger and others
- ignore and live with it and try to change your phone for anything else asap - samsung botched this and is making no effort i can see for a fix. If they don't care about you it's only fair you don't care about them either.
I'm aiming for a nexus4 when i find one cheap around. Plenty of power, 2Gb, fastest updates in the business. Should come down in price even more when any new phones hit the market.
This is a really big issue with this phone.
First of all, don't compare it to the iphone, cause the iphone doesn't actually multitask as it freezes apps in the background.
Start downloading something with safari and open another app in iphone. Then the download stops until you switch back to safari.
iOs multitasking philosophie is completely different to android.
Now, having paid 600euros and being unable to multitask is really frustrating. I've tried several things like different roms, external swap, internal swap, zram blah blah.
The truth is that although the stock touchwiz roms offer stuff like multi-window, they are really REALLY laggy in my opinion. I once decided to flash a cm10.1 (aosp) based rom. I haven't regretted since. I felt as if i had a completely new phone. I suggest you try such a rom. you wont regret it.
Also, there are some apps that allow you to freeze background processes. I use Rom Toolbox pro for example and i have frozen many background apps so I've reduced the amount of ram being used. Search on xda, there is a thread about which backgroung services are safe to be frozen.
Also, use greenify. Greenify stops apps from running in the background when you dont need them. Maps for example keep running in the background consuming 20mb for no reason. Greenify such apps so that they consume your ram only when you need them to do so.
Plus, change your LMK settings. The Low Memory Killer is an android service that kills apps when the amount of ram falls beneath a limit. Use an app such as Rom Toolbox to lower your limits so that apps don't get closed so often.
Finally, try zram with the appropriate settings. I use Googy-Max kernel which has bult-in zram support. I use 600mb of zram with 80% swappiness.
Having these things altered i can run at least 5 apps simultaneously without any problems. For example i run facebook and messenger along with whatsapp and skype. When i open the browser to search for something, none of the other apps gets closed.
Ofcourse if you try to run many apps, you may experience app-closing or lags. But remember, the key, is to close apps that you dont need.
Also, if your phone feels laggy just reboot it. For the next 24 hours you ll be fine without any lags.
Hopeless multitasking continues even on CM11 4.4.4. I don't understand what the reason for bad multitasking. When I switch from Dolphin browser to any other app and come just after 5 seconds I find it killed. Even I can't upload a photo to a browser. While I am selecting the, browser page was shut down.

[Q] What is the Best Android 4 or upper ROM for Legend?

I'm running B 0.8.4 Rom by BlaY0 on my HTC Legend for so long.
It is a very good Rom with no problem at all.
I want to change it to Android 4 ! but there are plenty of them here, each of them has some issues,
Could you please introduce the best STABLE Rom which its Android version is 4 or upper for HTC Legend?
Thank you in advance
I'm using Zeubea's CM10 rom (4.1.2). It's pretty stable and works great, I almost never have problems. Not sure if it's the best or most stable JB rom for Legend though. http://forum.xda-developers.com/showthread.php?p=33684845
That said it is a big rom so you may need to prune some useless system apps. There are lots that are just junk, I deleted 20-30 apps haha. Lots of room now and runs much smoother with less overhead.
I also recommend NOT flashing the gapps Zeubea provides. Just get them from Play. Some of the latest Jelly Bean apps are almost useless for me, like Maps. I installed an old version—I think the one from Blay0's rom in fact. Works much better. I find the stock browser way too heavy, too. Camera app is way too heavy, deleted. But all these can be replaced with stuff from Play.
Remember too that JB apps are bigger in general so RAM will be limited. Just opening Settings eats 30MB.
JB roms may also trash your wifi and gps. I had problems with both but it's working ok now. Legend wifi was never legendary though haha.
Anyway, just try it!
What you probably should look at is, what base do those "other roms" use, I think you will find more often than not they are based on zeubea's roms anyway, with some tweaks here and there. The op really should tell you in the thread so just have a read...

GPS problems:
You need to edit /system/etc/gps.conf
Use a root explorer like Root Browser to go to that file, and open with RB text editor. Or better yet, copy it to your computer and edit it there.
Change the file so it contains the information found here http://www.modaco.com/topic/331446-mod-all-roms-gps-fix/
Remove the # from the NTP_SERVER closest to where you live. If you want to add more servers you can look here http://forum.xda-developers.com/showthread.php?t=1200089
Removing apps:
If you have Link2SD (and you should!!!) you can try freezing stuff for a few days and then if nothing goes wrong, delete it.
As for what to delete, certainly the stock mail program, the CM file browser (USELESS), music app... I sorted by size and deleted anything that didn't sound useful / critical. I also deleted the AOSP keyboard. It's good but doesn't have Chinese which is a must for me. I just installed another keyboard from Play. If you delete those few things your system space will free up a bit and be more than enough to give it some breathing room. I'm not sure you need more than 20-30 MB free (or any free at all, I'm kinda talking out my ass a bit haha). But it seems to stand to reason that system apps need room to store data, cache, etc., and if they don't things will get choked up real quick.
What does matter is freezing useless apps and utilities that load automatically and sit in RAM. Legend RAM is very limited and while it's true that unused RAM is wasted RAM and that task killers are worse than useless, having stuff load automatically and keep themselves in RAM is just taking up space for useful apps that will use that RAM, without question.
That said anyone with a better understanding is more than welcome to jump in!
Don't talk to me about gps my threads on the topic are enough. Basically gps either works or it doesn't, if it doesn't your out of luck my friend!
