Stop or close an app - Nexus One Q&A, Help & Troubleshooting

What has everyone been doing to close apps since Froyo doesn't work with task killers? For me its not a matter of my Nexus getting bogged down sometimes I just want an app closed when I don't use it.

So lets ignore the fact that stopping normal running apps will slow down your phone and increase battery usage and assume you must have a good reason.
That reason must be the app is not behaving well, so just stop it from the Manage Applications section in settings.

Cool. Thanks.
Question though: how does stopping an app slow down the phone? Other than I guess the initial action. I have often wondered why a self shutdown isn't written into most apps such as on a desktop OS.

Android will keep the app in memory, but it will not run. So keeping it 'running' isn't using any battery. But if you decide to switch back to it, it is already loaded and ready to go.
If you force close it, then it needs to reload completely again when you go back.
When it is in memory it is not slowing down the phone, or taking any battery. If a new app needs the memory, Android closes the old app instantly without any noticeable performance issues.
So by forcing them closed you are forcing Android to spend more time and battery to reload it every time you go back. By leaving it open, you let Android do the best thing with it. Which means when you go back to it, it could still be there waiting.

[Q] I have 2 questions about my Captivate

I love my Captivate but 2 things bother me.
1) Why does the music player start every time I unplug the wired headset? I've tested and it's not running BEFORE I plug the headset in.
2) Why do so many apps automatically start in the background? I will use Process Killer to bring it down to 1 or 2 apps running and next thing I know, there are 7 or 8 and I haven't started any of them! This especially bothers me with the AT&t bloatware apps that cost extra to use.
Any info/fixes would be appreciated!

1) I have never heard of this happening to anyone before
2) there are allot of applications and processes that have dependencies on other applications and processes - they will need to be running for your phone to operate properly.
Don't fall into the idea that you need to manage the memory on your android phone the same way you would a windows machine. unless you have installed a bad acting or poorly coded application your android phone will shut down what ever processes need shut when they need shut down all on its own.
The only reason you should use or need any kind of task manager or task killer is to check every now and then to see if you do have a bad acting memory/cpu hog causing problems. too many people use task killers have them running in auto without knowing what they are doing and a dependent needed processes get killed and they can't figure out why their phone acts so buggy.
Thanks for the reply

Well then, Youtube running for no apparent reason at all would be a dependancy of exactly what?
Maybe the only reason YOU would need a task killer is what you stated above, I am using it to see what's going on on my phone and if I am in danger of ending up with charges I'm not willing to pay for. But thanks for the reply.

Using it to watch what your phone is doing learn what's going on is a good idea - but I would avoid shutting anything down until you do know why or what process started it - if you shut them down without knowing why they are running then you will continue to see them restarted for apparently no reason.
As for youtube, if you had been recently browsing the web one of the pages you visited may of contained a link to a file your phone has associated with youtube. Also you may have installed some app that triggers youtube, but just killing it without knowing why it is running may keep you from finding out what is going on and cause some other unexplained strange bug.
I have seen more than one person have their phone go from being buggy to running well when they stopped killing processes and turned off any auto killing functions of their task killer/manager and just watched their phone run for a couple days while letting the phone handle shutting processes down.
But as far as watching your phone closely and learning what it is doing, I am all for this - at the same time I don't want to be promoting paranoid behavior - but being informed and having a good idea what's going on with your phone wil definitely make you more capable of trouble shooting if and when the need arises.
And just be sure to check you bill every month and see what your being billed.
I found that removing the AT&T bloat to be almost mandatory to have a great running phone.
Couple that with the custom ROM's found here - and the device is awesome. I have no need to kill any processes. I do open up System Monitor to see what is going on with the device - but that is the beauty of Android - you can actually see EVERYTHING that is running on it.. and based on any errant process - you can kill it.
But.. there are a million articles on if Task Killers are a benefit or a hindrance to your phone's battery life and performance.
Bottom Line - be smart with your phone like your computer... don't download a bunch of crap, watch where you browse, and keep an eye on your sys monitor to see how your phone is behaving.

Joe, where is the System Monitor?
I've not come up with the nads yet to root the phone and remove the bloat. I'm not in any hurry, the phone runs great. As I tried to explain before, I'm curious as to why these applications end up running at random, without my even touching the phone. I will clear all apps from running and lay the phone down and not touch it. On my last look, 2 messaging apps were running, Youtube, AT&T Navigator, Where's my Droid and Gallery. Bear in mind, I had not touched the phone. I just cleared it again and will look after bit to see what has started.
I am also looking for any theories as to why my music player starts when I pull the headset out from being on a phone call.
Although appreciated, I am not looking for opinions on what I should and shouldn't be doing with my phone.
Lol. I just to trying a piece of advice - I know it is your phone and you can do with it what you please.
But go ahead and keep killing processes without knowing what your doing and see if you have more or less strange buggy behavior.
FYI - messaging apps are generally coded to almost continually sync in the background - to see if you have any new messages and will restart every time you stop them - if you want to know instantly of any new messages they will have to run
Att navigator - att is trying to shove this app on you so they have it set to start any time your phone starts any locating process - and your phone will almost continually be trying to figure out its location
Wheres my droid - is either trying to figure out where it is or preparing to figure out where is to be ready to let you know when you ask - if this program did not have something triggering it to keep it running all the time it would be a pretty useless piece of software don't you think
Gallery - pretty much any media syncing process wil start gallery - and allot of media processes have some type of background media sync process
As for youtube - I'm not sure yet

[Q] Select which apps run at start up???

Is there a way to select which apps you want to start up and run when the phone is booted? Since I've rooted I've had a lot more apps running right after turning the phone on (15-25 apps running). It is sluggish at start up, I'm assuming this is because the phone is trying to start and run a whole bunch of apps at the same time as well as obtain signal, check verify media on the SD card etc. and the processor is bogged down. Is there a way to select which apps I'd like to run at start up?
If you want to reduce lag try roms. Any app that tries to control what Is starting up will largely be ineffective
Any speculation as to why I never experienced this until after I rooted my phone?
Rooting should not cause programs to just start running.
Are you certain you have not added something else since root that may be causing lag?
I wouldn't describe it as general lag. It's only at start up. Once everything has loaded it runs the same it did the day I got it. It's just that it takes longer to boot initially. And when I use my task killer once everything is loaded it typically kills off 20-25 apps. Before I rooted I had a max of 6 apps running at start up. Currently I have 80 apps installed. Before I rooted I might have had 10 less apps.
Go to market, put startup in search, you should find several apps that claim to help with this
Thanks, I'll give that a try.
Startup Auditor. Works for me, give it a shot.

Sluggish and slow..

Suddenly my phone seems so sluggish and slow. Is there anything i can do except rebooting?
My iphone never got sluggish like this and i think i didnt reboot it for several months.

have a look and see what app/programs are running in the back ground, with android you can multi task and run several progrms at once, with the iphone you cant only one app at a time.
Some androind apps stay open and use up atlot of memory which could be slowing your phone down,
Download a free app called Auto memory Optimizer and stop all unwanted apps running in the background
Hope this helps
Thanks, but you need root for auto memory optimiser. Is there a way without rooting?

Try memory booster its free an can't see anything about needing root

What apps do you have running? The most likely cause is a badly coded app that is hogging CPU cycles, or memory, or both.
Froyo is pretty good at closing apps when they are not needed. A task killer won't help if the problem app just restarts itself.

I think i have found the problem. Juice defender. I've uninstalled it and the phone fells faster and without the slowdown when i unlock the phone for about 30 sec.
Anyone else have problems with juicedefender?
yep. don't install that. i've been hearing reports that it does slow-down or cause freezes on your phone.
Ok. Generally NO taskkillers or battery savers from now on :-D
Sent from my LG-P990 using Tapatalk
you can use watchdog. it monitors apps and can tell you what app are misbehaving. not necessarily a task killer but its definitely a useful app. does not slow down your phone.
Does anyone else's music get laggy and choppy when you listen? Cuz mine does and its annoying as hell. Definetely not something. I was expecting from a super phone. If I reboot then it stops for a while but back at it in no time. I'm on cm7 and use winamp and this also happened on the stock player. I have a minimal amount of apps and plenty of ram free but music still lag arghhh!!! Oh and this mostly happens at times when I either lock or unlock the phone or scroll thru the menu.
Edit: it just stopped randomly out of nowhere but I know it will come back I can just feel it.

Music lagging seems to be a problem in CM7 for some, on some builds. I have it sometimes, but it disappears after a while. CM7 is not stable atm, it'll probably be solved in the future.

Slow Performance?

Is anyone experiencing lag issues with the Note as it keeps apps open chewing up memory?
Galaxy Note
No. I have root and use Autorun Manager to to stop apps starting when they feel like it. There is no lag any more.
i think we have to keep killing apps when they are not in use in order to avoid lagging.

That will just waste more battery as the apps just pop up again.
If you don't need them, stop them starting. If they are no longer 'active', Android will dump them when required.
I truly believe the only way is to stop the ones you don't want starting from starting when they want to. I immediately increased battery life by 50%.

[Q] Z1 Keyboard and App Minimising Issues!!! ARGH!

Basically, I have a Z1 I'm running Android 4.3 On it. (and I in no way intend to get 4.4 anytime soon by the way).
It has started to get a bit buggy and laggy, a few white screens and slow loading times here and there but I can generally deal with that, what I can't deal with however is that:
1. Apps will randomly minimise and I'll go back to the home screen, when I try to go back to the app sometimes it works but usually it will come back for a few seconds and then minimise again or even just do it right away. This happens particularly when using Chrome, more particularly when I am zooming or trying to type.
Which brings on to issue 2:
The keyboard takes ages to load, like up to a minute after I've clicked in a text box, this can also cause apps to then minimise again, very frustrating not being able to type. This has also started to occur when trying to text, but it's mainly in chrome.
This would lead me to think that the RAM isn't coping very well, but I do try to clear caches and stop apps from running but still I generally only have between 120-150mb of free RAM, so what can/should I do?
I'm tempted to factory reset to be honest.
Thanks in advance for your help, I know that this forum is the place to be for Androiders. :fingers-crossed:

Factory reset is the only logical thing j could recommend, short of an update. Any reason as to why you're avoiding the kitkat update? It's running like a dream on my Z1

Yeah I thought that a reset might be the best option.
Well I've often regretted doing OS updates on my phones in the past, and KitKat has some funny privacy and content management rules that I thought might stop me from really benefitting from the freedoms that I originally loved so much from Android, or am I wrong? Can I still move Apps around? My girlfriend got 4.4 on her S4 and it really ruined it, UI got clogged with Apps she couldn't use or delete! :silly:
I don't really want to root my phone either so It's a tough decision! :
Thanks for your help.
KK to sdcard saving is easy
root takes 3 minutes
benefits ? 300000000000000 minutes of your life saved from the stress and headaches
keyboard and apps dont minimize (which is just a bonus)
For issue no.1, I used to have that. I ended up reinstalling my rom, ROMAUR 9.1, and actually reloaded all my apps via titanium backup but without their data. This helped my phone out a lot.
Before I did this, pressing the recent apps softkey button would minimize to my home screen and pressing it again would do nothing. I'd have to wait some seconds before the function would work properly. My ram would be ok as well. But I noticed it more while I was using Swype. Switching to Google keyboard made it act up less.
For issue no.2, as I said, Swype would be the main cause of lag. In some cases, it was responsible for my softkeys not being responsive. I'd have to press home and go to settings and switch the keyboard. Then it would function properly.
I think what it comes down to is the active apps running. Swype is a large apk so utilizes more ram than other keyboard apps. There may be other apps I can't narrow down to that help bog the device down.
I hope this helps!

SD Card management IS a pain. But, the advantages outweigh the cons. Given your situation, just do a clean install
