I am not saying it isn't loaded but it can't use the GPS, 3G or anything else on the phone.
To check which programs are running in the background use pTerminal.
Run "ps" for a list of processes
Run "kill <pid>" to terminate a process

We do make a good team LOL... I was thinking the same thing when I saw it... but I couldn't remember where I posted how to use pTerminal since everytime I try to kill a process it tells me I am not allowed LOL

What kind of processes you trying to kill? I didn't have any problems with the apps I launched... hrm
That's ODD, I just tried it and it threw an error, and it killed the app too. Wow interesting, i could have sworn it didn't throw that error before, but it killed the app. What about for you, does it kill the app anyway?

Do you use myfaves cuz if you don't then you can just uninstall it.

When I type in Run "ps" it doesn't show nothing.

It is ok... I thought the same thing and even cleared the data and still have issues.

Can anyone give an example of what the <pid>'s look like ?? Thanx

The PID is the number after the user that is running the file or service.
The first one in the line should look like this.
root 1 0 264 136 c00a5cd0 0000c36c S /Init
So root is the user and the PID is 1, they go in numeric order and on my phone go up to 3716
so if i wanted to kill /Init(which you can't) i would type in kill 1
which right now will throw me an Operation not permitted.

Thank u. U were very helpful and didn't take the "know it all" approach I am a technician more on the harware aspect of things so software sometimes gets tricky for me . Thanks alot

Changing apps the startup on reboot?

Now i have modded my phone i can see using the task manager for root how many programs automatically startup when i start the phone up.
Is this an issue? How can i change which apps startup when the phone starts up?

as far as i'm aware, you can't.
which does kinda suck, i must agree.
i can't imagine the apps will be much of an issue. most of them should be google apps anyway, so they should be fine left alone.

actually, a lot of apps on the market start at boot.

yeah, but as long as you don't have a stupid amount of apps installed, i can't see it causing much of a problem.

It could be very beneficial to control what starts at boot.
Hopefully we'll find a way quick.
Can't see it being too hard.
You should be able to append it to init.rc

Close program??

How do i close a program in the magic, i dont want it running in the background. Is there a prog like a taskmanager or something..??

Hi ,
Download "advance task manager lite" off the Market. This is a very very helpful app which can close all your programs running and very simple to use. And it is Free.
If you need anymore help feel free to post back

There is no such app in my market. Can anyone share a free version? Thanks

It's a free version. The actual name is "Advanced Task Manager Lite" so do a search on "Advanced".

I did do a search and can't find it. Anyone else managed to find it under Rogers in Canada?

I can easy find it. I use it every day, but i find it a bit strange that you cant close apps in any other way! And alot of programs doesnt have a "Quit/Exit" function.
Does anyone have any explanation to why its not possible to close programs without download extra programs?

you know,
I think i heard Something about when you leave the app , it does actually sort of close.
It saves the state you left it in (freezes) and unfreezes when you enter it again. So really the App is not running or using any comsumption at all until you are in the app.

This is true.
It is because android is awesome at app management. There is no real need for closing apps. It leaves apps kinda open (saves their state in ram) but not running. That`s why most apps open so fast. And even though more ram is "in use" it doesn`t cost you battery life.

Thanks for confirming ,
What a fantatic way , The OS is fantastic and I can guarantee that Android has alot of potential and Can only get better and come up with more technological breaking idea's!!

Oh i didnt know that!! Sounds really fantastic. I have to get used to a whole new way of thinking then, i think im too used to windows
Anyway. I love Android more and more. But i was shocked when i found out that you cant send or receive files via bluetooth. I hope this is their number 1. priority in the next released. I mean, comon .. phones have been able to do this for 10 years now!

i did not find it either. i m using rogers too
but you can download Close Everything at Market for free.
i think those apps are similar. the only difference is you have to close EVERYTHING instead of choosing an app to end it.
anyway, the system is not getting slower even i open lots apps.
maybe, the "freeze" thing is true

yesterday I had my phone fully charged before i got to sleep, in the morning 8 hours later the battery was almost empty. GPS and WIFI was disabeld, so I think all the programs in the "background" ( a lot ) killed the battery.
Or what do you think killed the batt?

that did not happen to me yet
if you disable background data usage in data sync that will save batt life and lower data usage too.
do not know if that helps at all

alarms still work (tested just now)
i do not know how that app works ~oops~
maybe it does not work at all hahaha

not all programs stop running. some are designed to run in the background
the only real way to check what is running is to use a task manager
I paid $0.99 for advanced task manager. Its a good, but basic app. And hardly breaks the bank at that price!
The other issue I get is "go slows" sometimes on the phone. It doesn't seem to crash, just response times go into the seconds. I switch off and on to soft reset and its fine.

Why should I disable data usage? If i have an app that use data, then I only need to close the app. Please correct me if I´m wrong.

Closing open applications

Is there any special way to close an application that you are in, or does tapping the home button close it? I want to make sure that I am not using up processor with crap I'm not even using at the time.

To close apps you would need to download a task manager from Market. The way Android is meant to behave is that it leaves apps open until another apps needs it's memory and then it automatically closes other background apps.

I downloaded Advanced Task Killer. Any pros or cons to this app or is there one better?

That's what I use and it works well for me. As you can choose which apps to leave open and which ones to kill. And it remembers so you don't have to select everytime.
Is there a better one? Maybe, but that one works well, is simple, quick, and easy to use.

Here is why you DON'T NEED a task manager..... do yourself a favor and read..

I'll double confirm that YOU DO NOT NEED a task manager (unless u need to kill a crashing app if u dont wanna reboot)..
That's how Android is, "background running" apps do not affect phone's performance, cuz they're not really "running" in the background.
Some apps (like Dolphin HD browser) have EXIT/CLOSE button when u press menu

Also hitting back instead of home will usually "close" the app

Update: After actually reading the article and a related one linked at the bottom
http://androinica.com/2010/05/07/go...-imply-task-killermanager-apps-are-pointless/
The Android Market has dozens, possibly hundreds, of task killer apps all vying for attention. I’m sure some people may argue that there’s some short-term value to these apps; however, it appears that task killers are not necessary and in some cases do more harm than good. An additional 20 minutes of use or short bursts of freed RAM can be great, but users shouldn’t compromise experience and overall health of their device for that extra time.
Let me be clear in stating that apps like Advance Task Manager or TaskOS have great virtues like batch uninstall and app switching that many people can still benefit from using. With that said, it seems that constantly killing tasks, apps, and processes is not in the best interest of your phone. Android already has the natural ability to do this effectively, so let the phone do its job.

Good read. It reinforced my belief that I don't need to manage tasks myself.

Android system/HTC Checkin using over 90% CPU

The HTC Checkin service is talked about quite a lot, as lots of people seem to have issues with it running all the time, and sometimes twice. No-one seems to know what to do with it though.
My personal experience of it is that it takes over 90% of my CPU and I need to restart Android as I can't actually kill it. (If it does close then it's starting again straight away.)
I'm currently using Mdeejay FroYo HD v3.7 and this is the only problem I have with it (other than the obvious camera issue).
Does anyone have any advice on how I can kill this app/service and stop it restarting? I'd ideally like it removed from my phone unless it's really, really important.

You can try using Titanium Backup to freeze it. If everything works without it then you can use it to uninstall it completely.

how did it work out for you? process smd_tty is now taking up 90% for me. just curious. thanks.

I used the freeze option in Titanium,as suggested, and it didn't have any detrimental effects, so I removed it and have not had any side effects. I'd say try the same and see how you get on.
Sent from my HD2 using the XDA App

what "freeze" option? i only see the ability to back up programs... Titanium had a taskmanager-like feature? Can you tell me where i can find thid feature? thanks.

It's only available in the paid version, but I think you can still see it in the free one.
Bring up the app list by clicking on "Backup/Restore" and then click an application. There's a freeze option in there.

i can't see the process smd_tty as an app or process in titanium. no listing for it.

It may be running as part of some other process then. Without knowing what it actually does I don't know what you could do about it.

thanks. that is what i thought. I take it that you are happy with your fix? ar you still getting the high cpu burn now? is the check in service virtually useless then?
