I don't mind using a task killer to get rid of needless programs but after reading all of this it seems like the verdit is still out whether it works or is even needed. My problem as a new user was that unless the ATK listed what an app or process did, I had no idea if it needed to be killed or not. I mean how are you suppose to know if Process: com.sec.android.app.sns should or shouldn't be killed?
Anything that combines "process" and "android", you want to leave alone. I use ATK as a memory manager...any app showing running that I'm not currently using, I kill it.
Example -- Current list and what I would do:
(Free Memory = 74MB)
Android System -- leave it
Dialer -- leave it
android.process.media -- leave it
AutoKiller -- kill it last
Swype -- leave it
SNS -- leave it
com.drweb:monitor -- leave it, Dr Web is my anti-virus
IcsService -- leave it
DRM protected content -- kill it or leave it
BatteryLife -- I can kill it, but it will continue to run since it's a monitor app on my home screen
com.google.process.gapps -- leave it
Angry Birds -- kill it
Jewels -- kill it
Device Management -- leave it
Calculator -- kill it
Settings -- kill it
android.process.acore -- leave it
messaging -- kill it
(Free memory now 186MB)
