HTC EVO 4G : Task Killers / Special Calls
Jul 25, 2010
I understand the concept behind not needing to use them when it comes to ram usage; if a program isn't active its ram can be released so it can be used by other applications.however, how does the android OS deal with cpu use by applications not active? this is the only reason i would think apps should be killed; there's nothing preventing them from using up cpu cycles while in the background.do they need to make special api calls to use cycles if not active?

I used to use Advance Task Killer and Auto Task Killer on my 2.1, but I think I read somewhere that with Froyo (CM6 flash) they are not needed?Do I need to worry about apps that I'm not able to close out normally, or will Froyo run fine or even faster without a task killer?

I have an app on my daughters phone that will not allow her to text and drive. The problem is she can use any task killer and kill the app and bypass the application. So my question is, is there a way to hide an app from the task killers, or have the app check to see if it is running, and if not restart its self?

I've read around alot about people saying task killers aren't needed because Android is Linux based (not windows) and can handle all the apps in the background so theres not need for a task killer. My question is arent there apps or services that take up alot of memory and shouldn't be constantly running (without you knowing that is) For example there are apps that constantly update (recieve data) like Mail or twitter or Anti-virus (which constantly is on the guard for new apps or settings being changed). I also noticed that after taking pictures with my phone camera it said the camera was running when i already closed it. i checked running services under the settings and the camera was taking 74% of my usage (i did refresh many times to make sure it was running). I've came to the conclusion that task killer is good for a few apps that are constantly running in the background but not as much for apps that don't constantly run in the background (like games, after you close them)

On froyo I have noticed that app killer is not killing the apps properly. When I kill the apps and then reopen them, it goes back to the last screen.

I searched for previous posts of this and found no less than 4 separate threads.I decided to post this anyway because all of the other threads I found were inexplicably in device-specific forums.An interesting article on Lifehacker with more information to backup the argument than I have seen elsewhere (above-referenced posts excluded).

I'm very new here and am not tech savvy at all. I'm about to get my HTC evo, but I have read some people say get a app or task killer while others say its bad for an adroid phone. So, let's say I don't get a task killer app at all, how do you close applicatons?

I've been reading a lot about the task killer and AV apps here, but I am wondering if
1 - are TK apps really nessessary? Does it help with battery life and why would you want to kill an app? I've read somewhere that TK apps are not nesscessary b/c android is a linux system.
2 - Can we get viruses on our phones? Are the Free AV apps we get here in Canada, since we cannot buy apps, good? Do they really protect our phones?

One thing i have noticed since i have made the jump to 2.2 is that apps keep restarting back up. I use Advanced Task Killer, and before i could open it up kill all my designated tasks after a reboot, and they would stay dead until they i restarted them again. But since the jump to 2.2 i kill all me designated apps, and 20 or 30 mins later, they are back up an running again.what gives?Is a better task killer needed?

I get that some of you are strongly convinced that task killers are of the devil. But the simple fact is this. When I got my Evo I was told to download ATK by the rep at Sprint. I put the widget on my home screen and used it like a dope fiend. And maybe I was self medicating, but my battery life sucked, and using it made my battery life suck less. Then, along came froyo, ATK stopped working, I read all the forums and got rid of ATK. Now my battery is worse than its ever been. I want to be able to look my apps and have them remain dead until I say so because its MY phone. That being said are there ANY task killers that work with froyo?

I've read enough to understand that task killing under froyo is not necessary to save the battery. However, I do not like the way applications tend to open in the exact same place that I "closed" them. More often than not, when i open an app, i would much rather start with the "home" page.This is especially true with the calendar and the web browser.Is there any app out there that can help with this?

I have had Advanced task killer installed about a week and its not really improving battery life noticeably. Also, when I look at open apps, random things like Sprint Navigation is open most the time, I haven't used it in weeks and if I keep killing it, how does it keep opening? Not really sure this thing does too much.

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.

My battery has never been worse since upgrading to Froyo. I don't use an auto task killer but I did use SystemPanel to manually close applications once in awhile. Now that I can't kill tasks easily, I just let everything run to see how it would turn out. I'm not saying the battery life is horrible, but it is noticeably worse now. I realize users experience will vary based on how many applications they have installed and running. I have not installed any new applications since Froyo.

There's a thread similar to this on one of the Hero forums. I tried to stop using the task managers on the hero, but I noticed a quite a bit of lag once stuff kept building up. On the Moment, I was running into several issues with apps, and I figured it was due to the task manager (i use advance task manager). So to test my theory I stopped using the task manager and the device works as it should. What i found was that even with a lot of usage, this device does not slow down. Not sure if it's the lack of the sense ui (i'm using open home), the fast processor, both or what but this phone can handle everything I'm throwing at it.My advice, stop using whatever task killer you're using. One less thing to worry about makes for a better phone experience.

I'm receiving a few emails per week with complain that my widget stopped working. In all cases when we do investigation the cause is some kind of task killer. What is worse that not everybody contacts me by email bug gives bad rating even if my application is not working incorrectly. I made remedy: wrote it to documentation (http://android.hubalek.net), wrote it to application main screen and wrote it do application description but people either don't know what exactly task killers do and how they work or just don't read doc.I think that Google should prohibit all task killers as they are malicious and are breaking other apps.

I notice there are a number of apps for dealing with turning off apps that are running in the background and using memory
1. Which is the best task killer app out there?
2. How much memory should you generally as a rule of thumb keep available at anytime?

I wanted to ask everyone what their experience is with task killers, because alot of people say their battery lasts longer with one but others say it does not make a difference.Can everyone post what task killer they use, and what difference it makes on their phone, or state that you do not use one, and why.
I used Advanced Task Killer Pro and when people were saying they were not needed, I uninstalled it, after 2 weeks I have noticed that my battery does not last as long as it did when I had the task killer installed, so I will be re-installing it.

When i first got my hero i was told to install a taskiller.I found this annoying and bothersome and my phone had several issues such as force closing and awake time.Then i read somewhere online that Android "is a smart os" and you don't need a task killer.So I uninstalled.Everything got better.My phone will lag or slow down here and there, but i think that's more the insufficient hardware of the hero.Usually I just wait a second and it's fine.Or press the home key.But here's the thing.I bought my wife an Intercept, and two best buy mobile employees told me to install a task killer - that this is how you "manage" android.Honestly, if this were true.Which I don't believe it is.I would not like the Android OS.But then a Sprint employee told me to also install a task killer.Only HTC has confirmed my earlier understanding that they're not necessary.So I've heard mixed things.In my own limited experience, it's not necessary.But i still see articles and forum posts talking about using them.So what is it? Are task killers a nagging and persistent myth.Or is there any real net benefit from using them? Or is it that they were more useful to version 1.5?

Question: My wife and I both have an Evo 4g. We live in the US. She will be traveling Europe for three months and I would like for her to be able to call me free through WiFi access. What app would be best for this situation? Something that is most like a normal phone call would be ideal. Also I would much rather be able to receive calls without running a special app. Simple and easy is important.

The so called "task killers" are sort of pain in my *** as users keep using it w/o understanding it, so I decided to check installed apps to find out if TK is installed and if so, warn the user about the potential consequences. Anyone got by any chance list of such apps (or packages) to share?

I saw a post today and was wondering if there is any truth behind this:"Task killers are pointless. Android powered phones have one built in, dont use one on my rooted nonsensikal froyo. Runs better then when I had it."

I've been using Task Panel X and Advanced Task manager to kill unneeded tasks and keep memory at a maximum.
Recently, every time I open Task Panel X and then revert back to Home screen I get the HTC logo and then a loading screen while the device sets itself. This happens even if I kill NO tasks.
So my solution was to uninstall Task Panel X and then use just Advanced Task Manager. All the sudden, same result.
Everytime I open either of these apps and then go back to home screen I get a BLACK SCREEN WITH HTC LOGO, THEN A BRIEF (10 SECONDS) LOADING SCREEN. THEN ALL IS NORMAL.

I'm writing an android program for adding task and deleting task in listview. I've add an onClickListener to the delete button so it can delete the task. However I was told I should not have the listener in the adapter violating mvc. how I can remove a task in my TaskListItem class. I got the method removeTask() in the adapter, but don't how I can use it in the TaskListItem class.
Code:
public TaskListItem(Context context, AttributeSet attrs) {
super(context, attrs);

I know this was talked about before at different times but I still have 3 questions.
1. what is the difference between a task killer and a task manager?
2. should we be using one of these apps or not?
3. when you look at the awake time if it is like 70% or 80% and you aren't using the phone a bunch I take it that means something is running,how can you find what is running.and is the awake time that big of deal?

Looking for a guide on how to use task killer. I had task killer on and deleted it. I think I was killing tasks that were needed to keep certain functions running that I use frequently. If someone would take the time to help me understand how to use one, I think I would be much more successful with it.
example - text messaging just stopped ( werrent receiving them ) . Once I took task killer off, everything started working again.
