YES, you need a task killer app for the Eris. PERIOD.

The funny thing about that argument is that people seem to think that it means that Linux has some kind of magical "memory is unneeded distortion field". Running Linux with a GUI, touch screen support, music, internet, etc. on 128MB or RAM won't exactly be a smooth and fluid experience even if the apps are open and not doing anything.

Free memory = wasted memory.

Harhar.
 
I don't have a task killer downloaded anymore, but I do use that 'Running Services' thing that on the 2.1 now. Even have a widget for it on my home screen. Works fine, but I rarely use it. In fact, I only use it cuz some game I downloaded for my son to play just keeps running on its on, even though he barely even plays it.
 
lets not continue this convo if you want a task killer coo if you dont then let it go simple and plain.
i not goin to say what i have or dont have because this is a useless thread for now until someone can actually say and prove that a spefic way makes EVERYONES phone run better there is no reason for this thread to continue thank you have a nice thread.
 
Java?!?! Seriously? :eek: no, DEFINITELY not Java... Thankfully!

From Wikipedia, the free encyclopedia
Android is an operating system and software stack for mobile devices that includes middleware and key applications,[4] and uses a modified version of the Linux kernel.[5][6][7] It was initially developed by Android Inc., a firm later purchased by Google, and lately by the Open Handset Alliance.

The managed code is Java which is the device controls, but it's sitting on a Linux Kernel
 
I have it installed, not running, just in case. I actually just had to use it today to kill Pandora since it locked and wouldn't respond. Killed Pandora and TK and went about my merry way and resumed enjoying Pandora

I have a DROID and I'm still up in the air about using one. I have TasKiller installed. (personal preference over ATK)...anyway...I have mine set to kill the TasKiller app as well when I kill the other things running. I also ignore some stuff from being killed so it won't affect much. For me personally, I do see longer battery life when using it. But honestly, not a HUGE difference. Maybe...an extra hour of standby time. I haven't really done any scientific trials to see what is better..with or without using one. It's kind of hard to duplicate the exact same usage on a day to day basis. Therefore, I can't really say it is totally beneficial. I still get my gmail sent on-time. I have background data set to sync automatically, i.e. FB..etc.
I understand that Linux allocates memory different than Windows...kills processes not being used to free up CPU and memory for something that may need it more at the specific time a new app is trying to run....blah blah blah.
I agree with hattrick that if you feel you need to use a task killer, then use it. If your phone works fine for your set-up and you don't think you need to use a task killer, then don't worry about it.
I don't do an extreme amount of multi-tasking at any given time so I probably don't need to use one at all. My memory never gets below..~70mb available free memory (or at least that's what the task killer tells me is available) so my performance never really suffers. The only time I have lag issues is if a specific app isn't working properly (bad coding by the dev). And to fix that I either update the app or get rid of it and try something different or simply make do without it.
Some of you ask to see proof that you truly NEED a task killer. I ask to see proof that you really DON'T NEED to use one. Just because Linux is supposed to free/kill and allocate memory differently, doesn't necessarily mean it does it, especially on mobile devices. While it may be true that better hardware reduces the need for such apps, lower spec'd hardware may need it..regardless of how well Linux is supposed to do it's job. There are probably a couple hundred billion possible combinations of apps/device settings that can be configured and throw in hardware as a factor and it's just too damned impossible to figure out what works and what won't.
Like I said earlier, if you wanna use one...then do so.
But it's probably not benefitting anyone to make a claim that you absolutely MUST HAVE one.

Sure, if you're just using it a regular phone you probably dont but this is a smart phone and most people use it for more than just a phone and checking Emails....there is no arguing here, multitasking without task killer apps is really slow.

The Eris and it's underlying OS are not multitasking. Neither is any version of Windows, mobile or not. Learn how something works before you start to make judgements on how it works.

here is my proof and source, i REALLY want to be disproved:

from my research, programs are going to run in virtual memory...if u have apps like i use (keepscreen, google maps, pandora) runnning in virtual memory...they are still running. using less (or no) memory...but still using battery. the OS has to maintain the state they are in...if the state is using gps or streaming...thats battery power being wasted.

"Linux uses a Least Recently Used (LRU) page aging technique to fairly choose pages which might be removed from the system. "

so it does kill processes by default...
however!
"When physical memory becomes scarce the Linux memory management subsystem must attempt to free physical pages. This task falls to the kernel swap daemon (kswapd).
The kernel swap daemon is a special type of process, a kernel thread. Kernel threads are processes that have no virtual memory, instead they run in kernel mode in the physical address space. The kernel swap daemon is slightly misnamed in that it does more than merely swap pages out to the system's swap files. Its role is make sure that there are enough free pages in the system to keep the memory management system operating efficiently. "

therefore...it can get to the point of OPERATING IN-EFFICIENTLY.
which would lead to sluggishness...even in the desktop OS.
and much like windows (mobile) linux does use virtual memory...having ALOT in common.
android is based off of linux kernel.

You have actually no idea how the OS runs or uses memory. Read a good text on the Android OS before you start spouting.
 
You don't need a task killer it just screws up your phone read the forum on why you don't need them. My phone has been running way better since I got rid of it trust me

Uh what lol??

Oh course they are multitasking..

No they are not. They give the appearance of it but they are not. Learn about how an OS operates before you make judgements about it. If you actually believe they are multi-tasking, you have no idea what that means.
 
Yes as apps are open but not used they will slowly swap memory with needed apps that are open. Look up why you don't need a task killer it will explain everything

Multitasking is keeping apps open to be used again when needed that's how your phone runs. Like having your music playing or the radio than checking email and texting pretty much at the same time. There is a forum on why you don't need em look it up

This is contrary to how electronic devices work. I am an electronics design engineer and an Android developer.

More items in memory do not take more energy. The memory still needs to be powered. More items in virtual memory do not take more energy. The virtual memory (disk) still needs to be powered.

There is not a selective shutoff switch on either device. It is either on or it is off.

If someone can define to me how a task killer works, I might believe them. What I do know is that Android and the underlying Linux OS manage all of this pretty efficiently.

I am new to the Android OS. Been using it since Jan. I currently have a G1 and my friend has an Eris. I use TaskPanel on my G1 when it starts to lag. The lagging I get on the G1 is on incoming calls the display can take 5-10 seconds to show who is calling and with scrolling through menus and such.
I started messing around for the first time on her Eris yesterday. I noticed that it lagged a lot when the keypad pops up and flipping through menus and such. I checked her download history on the Market and she only had 2 apps installed. She doesn't really dwell to much into the market, just got the phone cause it looked cool. I asked if it is always slow like this and she says yes and that's why she hates the phone. I installed TaskPanel and ran it to shutdown all the apps running in the background. I gave the phone to her and she was impressed on how much it improved the Eris. She went from having 28mb free memory to 70mb.
Its weird to me that there is no correct way to shut down apps on the Android OS. I recently switched from RIM OS and each app had an exit or quit option in the menu to fully shut it down. From reading this thread I realize that its not do to the Android OS but the developers fault for not putting in the code to shut down an app you won't be using for a while and leaving it running in the background.
I definitely like the Android OS. Very different from RIM's OS. Still think it needs more tweaks to it, but I see lots of forward progress happening.

Clean apps shut down using the "back" button. "Home" puts them in park. Learn how to use the phone by reading the instructions! Somebody went to a lot of trouble to put it all down in words.
