Android :: Multitasking / Task Killing Apps
Feb 17, 2010
I am considering getting a Motorola Milestone, which should ship with Android 2.something.I have a Nokia, and I really like the multitasking of the Symbian environment. How is it going to be different with Android? Is it a true multitasking os like Symbian or is it not, like the iphone? How do I switch from one application to another? Is there a button which shows all running apps? I read comments that, on some phones, switching from the web browser to another app and then back to the browser causes the page to reload from scratch. Is this still true or was it a limitation of older versions? Is there a task killer? I read very contradicting opinions on this, but I must say I do not understand why I should leave open an app I don't need, and how much an app left open uses system resources (battery life and RAM): I would have thought that its impact on system performance might have been minimal, but still > 0, right? Then why not close it altogether? Or am I missing something here?

I have tried 3 different task killers but each one do not seem to be killing the task even though it says it is. When i open the "killed" apps, they open to the last screen before they were killed. I am using the froyo ROM. On 2.1, when the apps were killed and then re-opened them, it always went back to the main screen.

I downloaded advanced task killer and select all the extra apps that I want to stop running however I can clearly see from the status bar that the app is still running. Things like brightness slider and stuff. Greenify seemed to actually really work but since I'm not rooted I cannot use that anymore.

I've been using a Task killer without problem since I got the Desire but since yesterday when reading through one of the threads on here and downloading a load of stuff the Task Killer has started behaving badly, I've tried two different Task Killers and they're both doing the same.
When killing some apps the screen seems to restart, like it killed the Sense UI but I've put all the system processes on the ignore list.

I just read this article:
Android Developers Blog: Multitasking the Android Way
and it talks about how Android itself handles multitasking. The problem I'm running into is this: I stopped using Advanced Task Killer because people are saying that it's not healthy for your device, which makes sense to me as it seems like you're using CTRL ALT DELETE to close a program every time, and that just doesn't seem like a good idea.I understand that this isn't windows and it works completely different, but I still stopped using it because it seemed a bit harsh.After reading the above article I realize that this is how Android itself closes apps, by "brutally killing them" as the article says.If this is how Android itself closes apps when it needs more memory, why are task killers not a good idea?
If somebody could dumb it down for me so I can understand I'd appreciate it, as I'm a total Android n00b.

Our application is defined to launch a SplashScreenActivity from Intent { action=android.intent.action.MAIN categories= {android.intent.category.LAUNCHER} . After the SplashScreenActivity does its work, it launches another intent to launch MainMenuActivity and finish() is called on SplashScreenActivity.
When we run our app for the first time on our phone, the SplashScreenActivity launches OK, and correctly launches the MainMenuActivity.
However, if we kill the app using TaskKiller, LOGCAT indicates that the application has been killed. I can't debug the app, because launching it from eclipse with the debugger makes it work OK, because it reinstalls the app. Perhaps there is a way to launch the app without reinstalling it?
Here is the Log of us killing our app...
When we launch the application again, the LOG messages for SplashScreenActivity are not logged and it looks from LOGCAT that Android is launching the MainMenuActivity instead. Here is the log...
Can someone Romaine, Diane help us understand what is happening? We saw this happening because some variables are initialized in SplashScreenActivity that aren't available with MainMenuActivity and we were getting NPEs.

Ok after seeing the somewhat heated threads on here about whether or not to use a task killer to help mange memory and improve performance on the droid Eris I decided to run my own little unscientific test.
So just a bit of background, Ive been in enterprise wide IT for 10 years now. I will say that my O/S knowledge is not exactly current but that may not be a bad thing for this. I will also state that what I report is just my own experience and I have not repeated is several times to validate anything. YMMV!
About four weeks ago my Eris was running like poo. Slow, lag city and getting almost unusable. I had been using Advanced Task killer quite liberally during this time trying to keep the device usable. Short term it seemed to help restore some of the response issues but it didnt take long before I was trying reboots to get the phone working well. Here is a list of apps I had installed at the time.
Pandora
Weather Bug
Shop Savy
Google Sky
Daily Dilbert
Bloom County
WiFi Analyzer
Silent Mode Toggle
Taskiller
SpareParts
battery Widget
Robot Guitarist
keyring reward
tv.com
NPR News
Movies
Shazam
Zedge
ip-calc
aldiko
JogTracker
UnitConverter
Backgrounds
photoshop mobile
plink art
Weather channel
Radar now
Last.fm
Plus a few others that had been removed.
That quite a few apps but not overboard in my book, and most seem to be pretty stable.
Anyway I decided to wipe the device and start over again, but with the debate raging I decided that I was not going to run any sort of task killer or other memory manager. And that I was going to run for at least four weeks and report the results. I will say I trimmed some of the redundant apps (weather bug replaced all the other weather apps nicely)
I have to say that over all I dont feel like I need a memory manager or task killer. It would be hard to say that the phone is a zippy as it was right after I wiped it, but as of now its no where near as laggy as it was before I wiped it. I feel my battery life is just fine, but I am not one who thinks that battery is an issue anyway. If there is 10% left when my head hits the pillow at night then I am a happy camper.
So this does beg the question what does using a memory manager really do for your experience on the phone? I cant for sure state that using a task killer caused my lag issues before, but it was not helping at the time either. My apps and usage have not changed very much other then not using a task killer and as of now my phone is running pretty darn well.
For me I am pretty firmly in the do-not-need-a-task-killer-camp for now. And before you flame or argue with me I challenge you to try it both ways for a while (with a clean wipe). I am sure that others have had a different experiences and maybe using one works for them.

I set my min free values on my phone so that it would be more aggressive in killing apps. But I don't want to kill juice defender when I hit kill all. Is there a way to make HTC task killer on sense 4 to avoid killing the app or setting juice defenders oom values lower?

I cannot figure out how to refresh a web site or facebook without killing the internet with a task killer. I can go back to the web or facebook hours after closing them and the same page comes up. Any tips for how to fix this?

Iv'e had nothing but weird problems since day one of my DroidX. I just received a DX hoping it was Hardware issue's (even though I was convinced it was software related). Everyone kept telling me it was because I rooted my droid, but I disagree.
Come to find out it was Advanced Task Killer causing my problems. I had it set to "Auto Kill" and set the level to "Crazy" and set it to "When Screen Turns Off".
It was killing my alarms, Killing Txt, VM, missed call Notifications, and restarting my phone because it was killing an important process....
IDK if anyone has already posted something about this (I didnt see anything) so I figured i'd throw it out there. Im still currently using ATK but the Auto Kill is turned off. Sending New DX back to Verizon.

I set my screen to use HOME versus Sense UI. Well, I put the ATM widget on my screen for single click app ends...when I do this, though, it kills home.
Anyway I can exclude Home from this. It doesn't appear to be an option in my Apps list when i open Advanced Task Manager
I have YET to receive a single email from androidforums.com when I use "Instant Email Notification" for thread replies.

Is there any difference between what happens when you use a Task Killer App to kill an app vs. what happens when the Android OS kills an app due to scarce resources? The Android SDK says that the Application.onTerminate() method isn't called when the OS kills an app due to scarce resources. So it sounds like the OS doesn't cleanly close apps and that it does exactly what the much-debated task killers do. If they do the same thing, then task killers don't do any more harm than the OS itself, right?

I installed it on my Droid and when I open the list and long press on an app it gives me the option to Auto-Kill. I assume this means I won't have to kill this app any longer so I select this option but I find that I keep having to kill the same apps over and over again. What's the point of Auto-Kill or what am I doing wrong? There are lots of programs (most I didn't even install) that run all the time and I'm having battery issues so I don't have battery to waste on programs I'm not using and will probably never use.

Does anyone think some of the issues people could be having are flash running in the background when you navigate away from a webpage to another app?
Since Android is a multitasking OS wont those mini apps continue running?

How do I jump between running/open apps? Yesterday I was playing spades and chatting with a friend on google talk. It was terrible. I could not jump between the game and the chat. I had to hit home button, then menu then Google talk, to go back to spades I could hold the down home button and jump back to spades from the popup window. I could not do this with google talk from spades because google talk was not in the recently opened apps popup window.

I'm a new Droid Eris user and I am constantly having to kill my apps in order to free up memory to keep my lag time and speed adequate. Will I continue to have to do this throughout the life of my phone? Why if I kill the Apps with Advanced Task Killer do the apps keep activating?

There are some apps like the NASCAR one that I will never need. Is it a problem to kill apps that are pre-installed on the EVO using ATK or one of the file/task manager apps? Any apps I should not kill for stability reasons?

I am a complete iphone guy but love the android equally considering I am a linux user But I love the simplicity of the iOS vs the android. Android still had some ways to go but I think I am going to get the evo 4g. My Q was, I love the way apple implemented switching of open apps on the iOS, whats the way of doing it on the android? Is it holding the home button as well?

I just installed Froyo tonight and reinstalled my apps and use Advanced Task Killer free and when I kill my apps it seems as though I always have some running or they will start running without me doing anything. I have News and Weather, Slacker, Voice search, and Skype mobile running and when I click on KILL selected apps It leaves Voice search running. If I click Kill again Slacker, News and weather and voice search are running. Why are these apps running when I'm not actually running them? Any ideas?

I have an EVO and I have a problem with it. I downloaded the app Advanced Task Killer to take care of apps running in the background. However sometimes when I pull it up I find that things like Sprint Navigation, Qik, Voice Dialer, and sometimes others are running without me pulling them up. My question is, how do I keep these apps from doing this, because they kill my battery when they come on and I don't know it?

I was wondering if anyone had any advice on which applications I should avoid/uninstall to try to conserve some battery. For example, does it use up a ton of battery to have location aware apps running or is it pretty nominal?

The app Clean Master claims it can extend battery life and device performance by killing apps--even offering a button to kill all apps. I thought killing apps was unnecessary since Android does this automatically when RAM is full and that killing apps manually actually drains battery life. What's the deal? Is swiping an app away from the Recent Apps List the same as killing an app? I currently do this often because the list is usually packed.

I want to change the limit android uses for killing apps when ram isn't enough. Now it seems to kill apps when free ram is less than ~30MB and i want to set it to 15 for example.
